  • How to reset mysql's replication settings completely, without reinstalling it?

    - by user38060
    I set up mysql replication by adding references to binlogs, relay logs etc in my.cnf restarted mysql, it worked. I wanted to change it so I deleted all binlog related files including log-bin.index, removed binlog statements from my.cnf restarted server, works set master to '', purge master logs since now(), reset slave, stop slave, stop master. now, to set up replication again, I added binlog statements to the server. But then I hit this problem when restarting with: sudo mysqld (the only way to see mysql's startup errors) I get this error: /usr/sbin/mysqld: File '/etc/mysql/var/log-bin.index' not found (Errcode: 13) Because indeed, this file does not exist! (I deleted it, while trying to set up a new replication system) Hmm, if I change the config line to: log-bin-index = log-bin.index I get a different error: [ERROR] Can't generate a unique log-filename /etc/mysql/var/bin.(1-999) [ERROR] MSYQL_BIN_LOG::open failed to generate new file name. [ERROR] Aborting The first time I set up replication on this system, I didn't need to create this file. I did the same thing - added references to a previously non-existing file, and mysql created it. Same with relay logs, etc. I don't know why mysql insists on trying to read the old folder. Should I just reinstall the whole package again? That seems like overkill. my my.cnf: [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] user = mysql socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp skip-external-locking bind-address = IP key_buffer = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 myisam-recover = BACKUP table_cache = 64 sort_buffer =64K net_buffer_length =2K query_cache_limit = 1M query_cache_size = 16M slow_query_log_file = /etc/mysql/var/mysql-slow.log long_query_time = 1 log-queries-not-using-indexes expire_logs_days = 10 max_binlog_size = 100M server-id = 3 log-bin = /etc/mysql/var/bin.log log-slave-updates log-bin-index = /etc/mysql/var/log-bin.index log-error = /etc/mysql/var/error.log relay-log = /etc/mysql/var/relay.log relay-log-info-file = /etc/mysql/var/relay-log.info relay-log-index = /etc/mysql/var/relay-log.index auto_increment_increment = 10 auto_increment_offset = 3 master-host = HOST master-user = USER master-password=PWD replicate-do-db = DBNAME collation_server=utf8_unicode_ci character_set_server=utf8 skip-character-set-client-handshake [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] #no-auto-rehash [myisamchk] key_buffer_size = 16M sort_buffer_size = 8M [mysqlhotcopy] interactive-timeout !includedir /etc/mysql/conf.d/ Update: Changing all the /etc/mysql/var/xxx paths in binlog & relay log statements to local has somehow solved the problem. I thought it was apparmor causing it at first, but when I added /etc/mysql/* rw, to apparmor's config and restarted it, it still couldn't read the full path.

  • can't delete some files or change their attributes on my FTP server

    - by Revolter
    I've installed a CMS on a shared host running Apache, now when I was deleting the root directory with FTP, some folders left with a "Permission denied" error and I can't change their attributes. the best explanation I've got is that the CMS installer has placed the files and has assigned its ownership to the Apache server instead of my user name. (i don't know it can be done) Ijust haven't use the uninstaller because I've lost my admin password - -" so how to delete those folders ?

  • Photobooth Program for Windows, and Cannon XSI that outputs to Picassa instead of a printer.

    - by Justin Dearing
    I am looking for a program that will allow a windows computer or a Windows CE device tethered to a Cannon xsi to act as a DIY photobooth. Price is not necessarily a factor, but I'd be quite interested in an open source solution. Instead of printing the photos I'd like to write them to a single Picassa album. If the software could be controlled by the Cannon's remote control. It would be a self serving photo booth for a wedding.

  • Server 2012, ADFS 2.1, and Office 365

    - by Matt Bear
    Has anyone gotten ADFS 2.1 on Server 2012 working with o365 SSO? I have it working up to a point, I tweaked the registry to allow the powershell commands to run, user accounts syncs fine. Even the remote connectivity analyzer shows no errors. But SSO itself does not seem to be passing the credentials correctly. Microsoft claims that ADFS 2.1 is not supported to work with o365, but I'm just being stubborn and not giving up that easy.

  • Our embedded linux system won't recognize a USB Device if it is plugged in before powerup. Suggestions?

    - by Blaine
    We are developing on a small embedded device. This device us a gumstix overo board running OpenEmbedded linux. We have our development almost completely done, and have run into the strangest of bugs that we can't figure out. We have a USB Device (Spectrophotometer) that has a USB2.0 Connection and an external power supply for the light source. Typical behavior is that you plug in the power supply, then the USB connection to a host. When the usb connection is detected by the device, the device boots up and enables the light source and fan. The device is then able to be used by the host system. The problem is that if the device is plugged into the Gumstix before we turn on the Gumstix, the USB Device apparently is not probed by the system (and hence does not turn on). Under a normal situation, when the connection is initialized by plugging in the usb cable, the spectro turns itself on and becomes available to the system (this can be seen via "lsusb" typically). Neither of these things are happening. There is no device detected via "lsusb" and no dmesg errors of any kind that we can see. It is as if the device is not plugged in. The device does show up and work fine if we unplug the USB cable and plug it back in once the system is booted up. It turns on and shows up on the usb bus, and we can access it with our driver. On any other desktop or laptop, it does not matter if the host system is on or off when we plug in the spectrometer. This behavior is what I would consider to be "normal" - that the usb system is probed and initialized at boot time, and the usb devices come online. In other words, our system is fully functional as long as we plug in the usb device after the system is booted up. Unfortunately this isn't possible in our final product - everything comes on at once. Additional Info: 1) We have tried a flash drive attached to the system when the system is turned off. Booting up the system brings the flash drive online, as expected 2) There are no messages regarding the spectro or usb device (using dmesg). "lsusb" only lists the USB hubs / controllers. It is literally as if the device is not present and not plugged in. 3) We have tried a brand new image from gumstix and an older image from last year. Both images have this problem. This problem exists on all 3 gumstix devices we use. Does anyone have any suggestions? From what I can tell it isn't really possible to do a complete "reboot" of the usb system that is a complete emulation of "unplugging" and "replugging" a usb device. I feel like what is happening is that there is no initial probe on the usb bus that would trigger the usb handshaking, but this is somehow specific to the spectro. This seems to be a kernel issue or at least an issue in how the kernel is initializing the usb subsystem. I'm not really sure though. I have tried the gumstix mailing list, but there doesn't seem to be anyone who has seen this issue before. Any advice or suggestions on where to start looking would be fantastic. Thank you!

  • Is it generally a bad idea to have other types of virtual appliances installed along side a firewall

    - by MGSoto
    I want to run my Firewall/NAT software (pfsense) and an internal NAS (looking at freenas right now) for my SOHO on one machine. Right now I have them separated on two different machines, but I'd like to consolidate them. Is this generally a bad idea? I see the security concern where if the firewall or host OS is compromised, then your data is essentially screwed. But is it really a concern for me?

  • Tomcat with virtual hosts - 404

    - by Thardas
    I have a CentOS 5.2 server set up with Apache 2.2.3 and Tomcat 5.5.27. The server hosts multiple virtual hosts connected to multiple Tomcats. For instance we have one tomcat for development and testing and one tomcat for production. project.demo.us.com points to dev tomcat and project.us.com points to production tomcat. Here's the virtual host's configuration: <VirtualHost *:80> ServerName project.demo.us.com CustomLog logs/project.demo.us.com/access_log combined env=!VLOG ErrorLog logs/project.demo.us.com/error_log DocumentRoot /var/www/vhosts/project.demo.us.com <Directory /var/www/vhosts/project.demo.us.com> Allow from all AllowOverride All Options -Indexes FollowSymLinks </Directory> ########## ########## ########## JkMount /project/* online </VirtualHost> JkMount line defines that we use online worker and our workers.properties contains this: worker.list=..., online, ... worker.online.port=7703 worker.online.host=localhost worker.online.type=ajp13 worker.online.lbfactor=1 And tomcat's conf/server.xml contains: <Connector port="7703" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" URIEncoding="UTF-8" maxThreads="80" minSpareThreads="10" maxSpareThreads="15"/> I'm not sure what redirectPort is but I tried to telnet to that port and there's no one answering, so it shouldn't matter? Tomcat's webapps directory contains project.war and the server automatically deployed it under project directory which contains index.jsp and hello.html. The latter is for static debugging purposes. Now when I try to access http://project.demo.us.com/project/index.jsp, I get Tomcat's HTTP Status 404 - The requested resource () is not available. The same thing happens to hello.html so it's not working with static content either. Apache's access_log contains: 88.112.152.31 - - [10/Aug/2009:12:15:14 +0300] "GET /demo/index.jsp HTTP/1.1" 404 952 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2" I couldn't find any mention of the request in Tomcat's logs. If I shutdown this specific tomcat, I no longer get Tomcat's 404 but Apache's 503 Service Temporarily Unavailable, so I should be configuring the correct Tomcat. Is there something obvious that I'm missing? Is there any place where I could find out what path the Tomcat is using to look for requested files?

  • Making application behind reverse proxy aware of https

    - by akaIDIOT
    https in tomcat being the hassel it is, I've been trying to get an Axis2 webapp to work behind a reverse proxy for ages now, can't seem to get it to work. The proxying itself works like a charm, but the app fails to generate 'links' (or ports as it concerns SOAP) using https. It would seem I need some way to let Axis2 know it is being accessed through https, even though the actual transport to it is done over http (proxied from localhost). The nginx config that proxies https to localhost:8080: server { listen 443; server_name localhost; ssl on; ssl_certificate /path/to/.pem ssl_certificate_key /path/to/.key; ssl_session_timeout 5m; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv3:+EXP; ssl_prefer_server_ciphers on; location / { # force some http-headers (avoid confusing tomcat) proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; # pass requests to local tomcat server listening on default port 8080 proxy_pass http://localhost:8080; } } The proxy itself works fine, the info pages of the webapp work. The problem lies in the ports generated in the .wsdl: <wsdl:service name="WebService"> <wsdl:port name="WebServiceHttpSoap11Endpoint" binding="ns:WebServiceSoap11Binding"> <soap:address location="http://10.10.3.96/axis2/services/WebService.WebServiceHttpSoap11Endpoint/"/> </wsdl:port> <wsdl:port name="WebServiceHttpSoap12Endpoint" binding="ns:WebServiceSoap12Binding"> <soap12:address location="http://10.10.3.96/axis2/services/WebService.WebServiceHttpSoap12Endpoint/"/> </wsdl:port> <wsdl:port name="WebServiceHttpEndpoint" binding="ns:WebServiceHttpBinding"> <http:address location="http://10.10.3.96/axis2/services/WebService.WebServiceHttpEndpoint/"/> </wsdl:port> </wsdl:service> The Host header does its job; it shows 10.10.3.96 in stead of localhost, but as the snippet shows: it says http:// in front of it in stead of https://. My client app can't deal with this... Adding proxyPort and proxyName to the tomcat6 server.xml in the default <Connector> doesn't help; I'm at a loss on how to get this to work properly.

  • Cloud computing?

    I'm an analyst and intermediate programmer working for a consulting company. Sometimes we are doing some intensive computing in Excel which can be frustrating because we have slow computers. My company does not have enough money to buy everyone new computers right now. Is there a cloud computing service that allows me to login to a high performance virtual computer from remote desktop? We are not that technical so preferrably the computer is running Windows and I can run Excel and other applications from this computer. Thanks

  • Link aggregation with freebsd8 and a cicso 3550, what am i doing wrong?

    - by Flamewires
    Hey, I am trying to setup Link Aggrigation with LACP (well, anything that provides increased bandwidth and failover using my setup will work). I'm running FreeBSD 8.0 on 3 machines. M1 is running 2 10/100 ethernetcards setup for link aggrigation using lagg. for reference: ifconfig em0 up ifconfig tx0 up ifconfig create lagg0 ifconfig lagg0 laggproto lacp laggport tx0 laggport em0 192.168.1.16 netmask 255.255.255.0 I plugged them into ports 1 and 2 of a Cicso 3550. then ran: configure terminal interface range Fa0/1 - 2 switchport mode access switchport access vlan 1 channel-group 1 mode active (everythings in vlan 1) Now Im able to connect the other computers to other ports on the switch and failover works great, i can unplug cables in the middle of a transfer and the traffic gets rerouted. However, im not noticing any speed increase. My test setup: load balancing: i tried dst and src on the switch, neither seemed to give me a speed increase. I am SCPing 2 500 meg files from the lagg computer to other computers (one each) which are also running 10/100 full duplex cards. I get transfer speeds of about 11.2-11.4 Mbps to a single host, and about half that (5.9-6.2) Mbps when transferring to both at the same time. From what I understood with destination load balancing the router was suppose to balance traffic headed for 1 computer over 1 port and traffic headed for another over a diff(in this case) the other port. With destination-MAC address forwarding, when packets are forwarded to an EtherChannel, the packets are distributed across the ports in the channel based on the destination host MAC address of the incoming packet. Therefore, packets to the same destination are forwarded over the same port, and packets to a different destination are sent on a different port in the channel. For the 3550 series switch, when source-MAC address forwarding is used, load distribution based on the source and destination IP address is also enabled for routed IP traffic. All routed IP traffic chooses a port based on the source and destination IP address. Packets between two IP hosts always use the same port in the channel, and traffic between any other pair of hosts can use a different port in the channel. (Link) What am i doing wrong/what would i need to do to see a speed increase beyond what i could do with just a single card?

  • Forefront UAG vs. Server 2012 Direct Access

    So I'm working on bringing my company into the 21'st century, with virtual servers, active directory, ADFS, SSO etc. Its a huuuuge project, with a future goal of ISO 27001 cerification. The current question is, does the Direct Access role offered by Server 2012 perform the same role as Forefront Unified Access Gateway 2010 does? I'm sure there are many differences, but my primary concerns are Sharepoint publishing, ADFS proxy, reverse proxy, remote connection, and o365 syncronization.
