  • How to configure Apache and Tomcat with vhosts?

    - by Umar Farooq Khawaja
    I have a server with a static, public IP address. I also have a registered domain name. For the sake of illustration, let's suppose they are IP Address: 12.34.56.78 Domain Name: example.com I have a single machine on which I am running the following: A website (over IIS7) available locally at localhost:80 A JetBrains TeamCity instance (over Tomcat) available locally at localhost:1234 A VisualSVN Server instance (over Apache) available locally at localhost:5678/svn I have set up an A record for example.com and the following CNAME records: www.example.com builds.example.com sources.example.com I would like to configure Tomcat and Apache such that: if I point my browser at builds.example.com, I end up at the JetBrains TeamCity instance and, if I point my browser at sources.example.com, I end up at the VisualSVN Server instance. I thought I could configure the Apache to vhost example.com:5678/svn to point to sources.example.com and added the following lines to the Apache httpd.conf file Listen 5678 NameVirtualHost *:5678 <VistualHost *:5678> ServerName sources.example.com DocumentRoot /svn </virtualHost> That broke the VisualSVN instance, so I had to revert that to Listen 5678 Help!

  • os x 10.4 Old, deleted user mail account problems

    - by Chris
    Hello- A while back I tried to add a user 'david' as a mail user on my OS X 10.4 server using dscl (I only had terminal access at the time, no ability to use workgroup manager). I could never get this account to work properly, so I deleted it. dscl . -list /Users no longer shows 'david' as an entry. I have since gained access via Workgroup Manager, and I am trying to re-create the 'david' account. Workgroup manager creates the account fine, along with an email account, which I can then log into via IMAP ('login david password' returns 'OK user logged in'). However, this mail account does not have an inbox, and I can not create one thru a mail client, IMAP or cyradm (they all say 'system I/O error'). When I re-delete this user, I can't find any record of him in any of the mail spool locations. Creating a user with any other name works fine (Inbox, mail access, everything). Any ideas on how I can get this user up and running again? -Chris P.S. - to create this user in the first place, I used dscl . create, then dscl . append /Users/david "some XML I found on the 'net" to add email privileges, if this helps...

  • Firebird 2.5 Database Corrupt

    - by BrendanH
    We have an issue where a database hangs the server when: a backup is performed (Hangs on a specific table) selecting * or count(1) from a specific table or viewing data that is related to the table (FKs, etc) We could browse the table to a certain point (using IBExpert) however after about 2900 records the machine just spikes and hangs. Performing a gfix -m does not work, and the validation reports back Record level errors = 4 (no matter how many times we run gfix -m, -v, etc. The Firebird.log file reports back these types of messages: Relation has 91631 orphan backversions (9214273 in use) in table BINS (137) - {Which is apparently just a warning} Unable to complete network request to host "MHPLZA1". Error reading data from the connection. INET/inet_error: read errno = 10054 SERVER/process_packet: broken port, server exiting Shutting down the server with 1 active connection(s) to 1 database(s), 0 active service(s) - {If we leave the backup to run while hanging, it eventually logs this error message} The setup is: The table is question has about 7000 records. The Firebird version is 2.5 Classic Server x64 install. The OS is Windows Server 2008. This is a virtual machine (VMWare) running on a massive server. (Does anyone have issues with VMs and Firebird?). We have the same setup running fine on other servers (However they are not virtual machines). Is there anyway to pin point the issue and or the cause?

  • unreadable corrupted ntfs partition - lost clusters reported

    - by Eduardo Martinez
    partition magic is reporting multiple 'bad file record signature' and 'lost clusters' errors on my 250GB samsung sata disk (connected via usb on a xp sp3). Unfortunately PM is unable to fix. PM shows the drive as being NTFS, detects used space ok and also drive name. But PM browser (right click on partition, browse...) won't show anything (as if disk was empty) Windows Explorer is not even picking the drive name and reports 'the file or directory is corrupted and unreadable' PTDD partition table doctor demo tells me the boot sector is fine, and I can see all disk content on its browser - but crucially cannot copy that content over to a new disk (PTDD browser is pretty arid to say the least) Also tried - photorec-6.11.3 - it actually started to extract files but wouldn't keep file names or any folder structure (maybe I missed sth on the configuration options) - find and mount - intellectual scan went well, the only partition on the disk was detected, then tried to mount into p: but got this error on windows explorer: 'p:\ is not accesible. The media is write protected'. Find and mount allows you to create an image from partition but I don't have a disk big enough at hand. Does anyone know if this will keep the extracted files/folders structure intact? I'm starting to think the disk is pretty screwed and my chances to recover this data are slim. Please someone enlighten me with that marvellous piece of software I am missing :-) Thanks in advance

  • mysql master-master setup as a way to simply master-slave promotion

    - by Chris Go
    I'm trying to see if the following plan is viable. Goal here is to be able to do HA (uptime) and not necessarily for load -- writes are fine on one MySQL 5.5 server (with innodb) but not really possible when the database is down. Currently, I have a master-slave replication setup which works fine except it doesn't have automatic promotion (obviously). what I am planning on doing is setup master-master replication to possibly do this "automatic promotion" using Amazon Route 53 DNS Failover (Health checks). What I am trying to avoid is to NOT have to do the auto-increment trick because the "business folks" got used to the auto-incrementing PK as consecutive numbers (yeah, I know this is bad but data is from 2004). So, setup the master-master replication WITHOUT the auto-increment collision prevention bit. The primary master is db1.domain.com and secondary master is db2.domain.com In Amazon Route 53, setup DNS Failover record for db.domain.com - primary failover is db1.domain.com - with a TCP healthcheck on IP address port 3306 - secondary failover is db2.domain.com - with a TCP healthcheck on IP address port 3306 Most of the time (99%), unless tcp://db1.domain.com:3306 is dead, db1.domain.com will be served up on DNS hits to db.domain.com. In fact, hopefully this is 100%. The possible downsides of this is the loss of a primary key (collision) and I think I am OK with losing one order. We are a low data volume B2B business and can just call our client up if this occurs (like an order disappearing). Does this sound like a good plan? Then I will also run another slave replication on db1.domain.com as "master" to a slave-db1.domain.com -- not sure why, maybe for heavy SELECTs?

  • cpanel dns only / rdns questions

    - by Clear.Cache
    I started getting IPs from ARIN directly, instead of the data center I'm colocated at. Now I have to start applying rdns myself for my clients upon request, instead of having the NOC at the DC do this. That is obvious, since I am in full control over the IP delegation and therefore have nameserver authority. The question is, how do I "create" ptr / rdns records for my clients? My current server uses Cpanel / WHM with ns1/ns2.mycompany.com I also applied those as dns nameservers in the ARIN IP's whois record. How do I create rdns for my clients? Should I install Cpanel DNS Only on a entirely separate server and use this method instead? http://layer1.cpanel.net/ If so, how can I seamlessly transition over the dns records to that new dns server, retaining my ns1/ns2.mycompany.com and their ns1 and ns2 IP addresses? Even more important: I have to change the ns1/ns2 IPs to the new ones I retrieve from ARIN. How can this be done, avoiding downtime during the dns transition? On a side note, would it be easier to just install Cpanel DNS Only on a dedicated server and just use dns1.mycompany.com and dns2.mycompany.com with their own dedicated ns1/ns2 IPs from ARIN - and utilize this dns server for customers who request rdns? Would this be a more viable solution than using our current ns1/ns2.mycompany.com Nameservers? Is Cpanel DNS Only a standalone software that does not require Cpanel/WHM on another server? Is it possible to have redundant dns servers setup using this software solely, ns1 on one server and ns2 on another? Thanks.

  • Amazon AWS EC2 + Puppet, get Puppet to know AWS instance tags

    - by Piotr Jasiulewicz
    I am having a problem with my AWS deployment, fairly new to AWS and Puppet. So coming to my question - can you distinguish puppet nodes with AWS machine tags or CNAME domains? A little background about the plan: have multiple clusters of machines, one php cluster, one legacy php cluster, one java cluster, one perl cluster control configuration with puppet - still pretty new to puppet but as a developer I like the idea of being able to version control configuration of servers have autoscaling enabled on those clusters - obviously the main benefit of the cloud that makes the much hight cost when it comes to any reasonable performance worth it (those amazon machines are slower than my phone...) deployment controlled by Capistrano, this makes things a lot easier So in AWS you get those super nasty public/private machine dns's... no way you can identify machines on those. In order to easer the problem, seams like AWS want's you to tag everything - so I did. Found a script that makes a CNAME record for each machine with the tag "ShortName" thanks to the Route53 API. Every machine has a ShortName tag that becomes its CNAME, unfortunately puppet still resolves the private dns name. I'd like to have node 'perl-cluster'{} in puppet, anyone any clue ho to achieve this? Thanks

  • How can i link a oracle user to a business objects user

    - by Robert Speckmann
    I have a problem with linking the oracle user to a business objects user. I will try to explain it as detailed as possible; I have a Oracle database (10g) where a couple of users are defined. These users can query on information with application X. Those records will then be written into the oracle database. The records that is written into the database has a ID that links to the person that has run the query. I also have a active directory in wich a couple of users are made; testuser1, testuser2. When those users log on, and want to load a report in Business Objects XI i want them to see the information that was created when the report was activated by that same user that had runned the query before with application X. The name of the person in the active directory and the name in the oracle database are not the same but i dont think that would be a problem in this stage. So the steps i took: First, i run a report in application X (with a account prodpim_rs) wich fills my Oracle database with a record. The second step is logging on as testuser1 (from the AD) and then login on Business Objects XI with the account. Now i want to load a report with the information in my Oracle database. So the prodpim_rs user and the testuser must have a link between them. I am wondering how to forfill this. Can i link the account, wich is made in a Oracle database, with the user of BO wich is linked to my AD? Thank you in advance for your reply Robert

  • Our application is responding different on client server

    - by WtFudgE
    I have an application running on our local server and it works perfect. However when I deploy my application to our client's server there are problems. If i copy all the sources to another local from their server, it works fine again.... I am talking about an ASP.NET application talking with windows server 2008. The server specs of our client are: intel Xeon 2.13 GHz 6 GB RAM 300 GB HDD windows server 2008 R2 Although I think it's not that important I will describe the problems I am talking about to give u a better idea: It is related to upating and deleting fields in the sql server. Whenever there is more than one user running the application, and updates or deletes (not even the same record!0, there seems to be fields updating/deleting wrongly. But as I said before, if we copy the source to another server it is not the case. So I assumed it is more configuration related. Do you guys have any idea what the issue could be? Thanks a lot EDIT: my client old me he disabled the sql related accounts Could this be related?

  • How should secret files be pushed to an EC2 (on AWS) Ruby on Rails application?

    - by nikc
    How should secret files be pushed to an EC2 Ruby on Rails application using amazon web services with their elastic beanstalk? I add the files to a git repository, and I push to github, but I want to keep my secret files out of the git repository. I'm deploying to aws using: git aws.push The following files are in the .gitignore: /config/database.yml /config/initializers/omniauth.rb /config/initializers/secret_token.rb Following this link I attempted to add an S3 file to my deployment: http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/customize-containers.html Quoting from that link: Example Snippet The following example downloads a zip file from an Amazon S3 bucket and unpacks it into /etc/myapp: sources: /etc/myapp: http://s3.amazonaws.com/mybucket/myobject Following those directions I uploaded a file to an S3 bucket and added the following to a private.config file in the .elasticbeanstalk .ebextensions directory: sources: /var/app/current/: https://s3.amazonaws.com/mybucket/config.tar.gz That config.tar.gz file will extract to: /config/database.yml /config/initializers/omniauth.rb /config/initializers/secret_token.rb However, when the application is deployed the config.tar.gz file on the S3 host is never copied or extracted. I still receive errors that the database.yml couldn't be located and the EC2 log has no record of the config file, here is the error message: Error message: No such file or directory - /var/app/current/config/database.yml Exception class: Errno::ENOENT Application root: /var/app/current

  • "A disk read error occurred" when booting XP disk image in VirtualBox

    - by intuited
    I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

  • Setting up dnsmasq for a local network

    - by WishCow
    Me, and a small group of developers have just moved to a new office, and I'd like to set up dnsmasq on our development server, so when we deploy web apps there, we don't have to edit our own hosts files. We have a router at 192.168.3.1 which we don't have access to. I figured I'd install a DNS server on the development box, and we all record it's IP as a secondary DNS server. Unfortunately I'm strugling to make this work. The name of the devel server is devbox, it's IP is 192.168.3.99, and it's running the latest Ubuntu Server (Karmic) My computer is running Ubuntu Desktop (Karmic) What I'd like to achieve Let's say I have three websites, website1, website2, website3, running on the development box. I'd like to access them by the urls: http://website1.devbox http://website2.devbox http://website3.devbox So I have configured Apache on the devel box, installed dnsmasq, and put the following lines into it's hosts file: 192.168.3.99 website1.devbox 192.168.3.99 website2.devbox 192.168.3.99 website3.devbox and edited my own resolv.conf file to include the devel box as a nameserver: nameserver 192.168.3.99 It's working fine, I can access the sites. The problem is that it doesn't scale well. I'd like all the domains ending with .devbox forwarded to the development box, and this is what I'm struggling with. I have tried putting 192.168.3.99 devbox into the hosts file, and editing the line in dnsmasq.conf: # Add local-only domains here, queries in these domains are answered # from /etc/hosts or DHCP only. local=/devbox/ But I cannot get it working. If I try any url that is not explicitly present in the development box's hosts file, the dns lookup fails. Is the local directive for something else? Am I looking at the wrong place?

  • Apache Virtual host not recognized

    I've been using one server, then I reinstalled everything on another server, and the mod_jk stopped working. Here is the situation: apache 2.0 sitting "in front" mod_jk used to connect to the apache to tomcat tomcat 6.0.26 used to server the actual requests I followed this tutorial. The result is: accessing http://mysite.com opens the index.html in /var/www/ accessing http://mysite.com:8080/ works OK the logs at /var/logs/apache2 show everything is OK: [Mon Mar 29 22:01:53.310 2010] [28349:3075389184] [info] init_jk::mod_jk.c (2830): mod_jk/1.2.26 initialized [Mon Mar 29 22:01:53 2010] [warn] No JkShmFile defined in httpd.conf.

The domain name is the same (I updated the DNS record today, and it has refreshed successfully) So the question is, what can go wrong? Is there another place where problems would be logged, if such occur? Update What I can be almost certain of is that the virtual host is not recognized. It is always forwarded to the default virtual host. So, how to make sure the virtual host is recognized and working?

  • Can IIS (Ideally Azure) do SSL Proxying?

    - by Acoustic
    My team has been asked to add a new feature to a project we're working on, and none of can find authoritative details on whether it's possible with Windows/IIS. The short of it is that we're hoping to have customers update their DNS with a CNAME record to point their website to our server instead of theirs (they why's are trivial - it's what the app does on behalf of your site). We're using a reverse proxy with several custom modules to serve particular content from the original servers. So far everything works perfectly until we encounter SSL. Is there a way to have IIS serve up an SSL certificate from another server? In other words, is there a way to be a trusted man in the middle? I'm hoping that's possible so that we don't have to require all our clients to re-issue their SSL certs. Frankly, we don't want to have to manage hundreds of certs. I'd also like to avoid a UCC situation if there's a way to because it seems to require re-creating the cert each time a client is added. So, any pointers on proxying/hosting SSL (or even dynamic SSL hosting like http://www.globalsign.com/cloud/) would be appreciated.

  • AjaxControlToolkit JavaScript is not pointing correctly on IIS7 running behind Apache mod_proxy

    - by sohum
    So here's my setup. I've got a DynDNS account since I have a dynamic IP. I have Apache listening on port 80 and IIS7 on port 8080. I don't want users to have to enter in mydyndns.dyndns.com:8080 to get to IIS7, so I've added the following code to my Apache httpd.conf file to enable a proxy/reverse proxy: <VirtualHost *:80> ProxyPass / http://localhost:8080/myASPSite/ ProxyPassReverse / http://localhost:8080/myASPSite/ ServerName myaspsite.mydomain.com </VirtualHost> I've got a CNAME record set up on my DNS so that myaspsite.mydomain.com redirects to mydyndns.dyndns.com. When I type in myaspsite.mydomain.com into my browser, everything works beautifully... mostly. IIS7 serves up the ASPX pages and visitors to the site don't know any better. A problem arises, however, when I add Ajax Control Toolkit controls into my ASPX website, because these generate JavaScript and apparently mod_proxy_html isn't geared to handle the JS URIs properly. Sure enough, when I open up the source of my ASPX page, it has script elements as follows: <script src="/myASPSite/WebResource.axd?xyz" type="text/javascript"></script> <script src="/myASPSite/ScriptResource.axd?xyz" type="text/javascript"></script> Sure enough, these scripts are attempting to be resolved at http://myaspsite.mydomain.com/myASPSite/WebResource..., which through the proxy translates to localhost:8080/myASPSite/myASPSite/.... How can I solve this problem. The couple of websites I found suggested turning on ProxyHTMLExtended but when I tried doing that, the server did not start. I'm guessing I didn't know how to do it properly. Anyone has a handy couple of config lines that I can add to my Apache conf file to get this working as I need? I'm using Apache 2.2.11. Thanks!

So, I've installed nginx-extras on Ubuntu 12.04 (it's built with PAM module), and write to site config: location ^~ /restricted_place/ { auth_pam "Please specify login and password from main_site"; auth_pam_service_name "nginx"; } Afterwards, in /etc/pam.d/nginx: auth required pam_script.so dir=/path/to/my/auth_scripts And wrote simplest /path/to/my/auth_scripts/pam_script_auth (also I've tried to write complicated scripts) #!/bin/sh exit 0 # should allow anyone Doesn't work. The script is launched (I've wrote full functional script, that successfully executes, check credentials, writes to its own log and returns correct exit code, and executes noticeably long). But no access granted. Only rejected. In /var/log/nginx/error.log appears next record: 2012/09/13 10:44:42 [alert] 1666#0: waitpid() failed (10: No child processes) If I'm specify in /etc/pam.d/nginx: auth required pam_unix.so and grant for www-data user right to read /etc/shadow, unix authorization works fine. But script auth doesn't work. Can't understand, where is trouble. In nginx module, or in pam_script module.

  • Is my dns server being attacked? And what should I do about it?

    - by Mnebuerquo
    I've been having some intermittent dns problems with a web server, where certain isp's dns servers don't have my hostnames in cache and fail to look them up. At the same time, queries to opendns for those hostnames resolve correctly. It's intermittent, and it always works fine for me, so it's hard to identify the problem when someone reports connectivity problems to my site. In trying to figure this out, I've been looking at my logs to see if there are any errors I should know about. I found thousands of the following messages in my logs, from different ip's, but all requesting similar dns records: May 12 11:42:13 localhost named[26399]: client 94.76.107.2#36141: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#29075: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#47924: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#4727: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#16153: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#40267: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63507: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63721: query (cache) 'burningpianos.org/MX/IN' denied May 12 11:43:36 localhost named[26399]: client 82.209.240.241#3537: query (cache) 'burningpianos.com/MX/IN' denied I've read of Dan Kaminski's dns cache poisoning vulnerability, and I'm wondering if these log records are an attempt by some evildoer to attack my dns server. There are thousands of records in my logs, all requesting "burningpianos", some for com and some for org, most looking for an mx record. There are requests from multiple ip's, but each ip will request hundreds of times per day. So this smells to me like an attack. What is the defense against this?

  • Changing Domain Name DNS to Redirect web traffic to one server, and leave mail to original server

    - by David S
    Hi there, Ok, quite the idiot with DNS.. apart from the basics. I have a domain name hosted with a domain registrar. It seems to have full DNS control (i.e. ability to view/edit A Records, Mail etc..) We have recently setup a server at Rackspace which hosts the new website The original/existing server (where the old website still is and Mail) is on another shared hosting companies server I went to the domain name registrar, and checked out the DNS management as follows: click here to view the DNS screenshot So obviously the A Record is pointing to the actual server where the website/mail is I figure, and the CNAME is pointing (alias?) to the website url. So my question is this: If I want the web traffic portion to go to the Rackspace/new server, but keep the mail going to where it is now, what do I have to change? Also, should I even change this info at the domain registrar? the rackspace server account has full DNS which seems to suggest I can point to their nameservers and then re-direct the MX (Mail) traffic to where the mail server is? Sorry if that was a bit confusing.. obviously in need of DNS training ;) Any help very appreciated. David.

  • Port forwarding for samba

    - by EternallyGreen
    Alright, here's the setup: Internet - Modem - WRT54G - hubs - winxp workstations & linux smb server. Its basically a home-style distributed internet connection setup, except its at a school. What I want is remote, offsite smb access. I figured I'd need to find out which ports need forwarding and then forward them to the server on the router. I'm told in another question on SF that multiple ports will need forwarding, and it gets somewhat complicated. One of the things I need to know is which ports require forwarding for this, and what complications or vulnerabilities could arise from this. Any additional information you think I should have before doing this would be great. I'm told SMB doesn't support encryption, which is fine. Given I set up authentication/access control, all this means is that once one of my users authenticates and starts downloading data, the unencrypted traffic could be intercepted and read by a MITM, correct? Given that that's the only problem arising from lack of encryption, this is of no concern to me. I suppose that it could also mean a MITM injecting false data into the data stream, eg: user requests file A, MITM intercepts and replaces the contents of file A with some false data. This isn't really an issue either, because my users would know that something was wrong, and its not likely anyone would have incentive to do this anyway. Another thing I've been informed of is Microsoft's poor implementation of SMB, and its crap track record for security. Does this apply if only the client-end is MS? My server is linux.

  • Can't Login to phpPgAdmin

    - by Devin
    I'm trying to set up phpPgAdmin on my test machine so that I can interface with PostgreSQL without always having to use the psql CLI. I have PostgreSQL 9.1 installed via the RPM repository, while I installed phpPgAdmin 5.0.4 "manually" (by extracting the archive from the phpPgAdmin website). For the record, my host OS is CentOS 6.2. I made the following configuration changes already: PostgreSQL Inside pg_hba.conf, I changed all METHODs to md5. I gave the postgres account a password I added a new account named webuser with a password (note that I did not do anything else to the account, so I can't exactly say that I know what permissions it has and all) phpPgAdmin config.inc.php Changed the line $conf['servers'][0]['host'] = ''; to $conf['servers'][0]['host'] = '127.0.0.1'; (I've also tried using localhost as the value there). Set $conf['extra_login_security'] to false. Whenever I try to log in to phpPgAdmin, I get "Login failed", even if I use successful credentials (ones that work in psql). I've tried to go through some of the steps noted in Question 3 in the FAQ, but it hasn't worked out well so far there. It likely does not help that this is my first day working with PostgreSQL. I'm farily familiar with MySQL, but I have to use PostgreSQL for the project I'm working on. Could anyone offer some help for how to set up phpPgAdmin on CentOS 6.2? If I've done something terribly wrong in my configuration so far, it's no big deal to blow something/everything away, as it's not like I've stored any data there yet! I appreciate any insight you may have!
