  • Can I host multiple sites with one Amazon EC2 instance [duplicate]

    - by user22
    This question already has an answer here: Can you help me with my capacity planning? 2 answers I currently have VPS server and I pay around $75 per month and I get: 40GB HD 2Gb RAM 100GB BW 6 core cpu (but i dont use much) I have only one live website running and traffic is only max 100 user visit per day. I mostly do the my testing stuff and some of my inter sites for playing with coding. But I do need one server. I am thinking of moving to Amazon EC2 if the price diff is not so much because then I can learn some more stuff. I am thinking of getting the 3 years Heavy utilization Reserved instance because my server will be running all day and night. I tried their online caluclator with Medium Instance Heavy reserved for 3 years for EC2 it comes $31 per month(effective price) and for EBS and S3 , I think even if thats it $40 for all other stuff. I will be at no loss for what I am getting at present. Am i correct or I missed something?? Now In my current VPS I have Apache for PHP sites and MOD wsgi for python sites. I am not sure if I will be able to do all that stuff in Amazon EC2. Can I host python and PHP sites both in Amazon EC2 instance using Named Virtual Hosts and Ngnix

  • some HTTPS sites getting blocked on one machine in network

    - by shadowfoxmi
    I have a few computers connected to the internet via a router. I have been having some trouble with this one Windows 7 desktop. I can browse most of the sites without any trouble but some sites where the sign in page switches to a secure connection (https), the page does not load. It's not all of the sites though. I'm able to sign into gmail and a few other services that I know use https . The sites I'm having trouble with; yahoo's sign in page and the one that I have been using to test across different systems, http://iforgot.apple.com (which switchs to https) ;this particular site, i can access from other computers on the network and my phone. I only have windows firewall running and AVG. I even tried to stopping windows firewall but it did not help. Everything was fine last week. All I have installed in the past week is VOIP softwares namely skype, ooVoo and windows live messenger. I'm not sure how to find out what's being blocked and why and how to unblock it? Any suggestions would be greatly appreciated.

  • Upon reboot, Linux software raid fails to include one device of a RAID1 array

    - by user1389890
    One of my four Linux software raid arrays drops one of its two devices when I reboot my system. The other three arrays work fine. I am running RAID1 on kernel version 2.6.32-5-amd64 (Debian Squeeze). Every time I reboot, /dev/md2 comes up with only one device. I can manually add the device by saying $ sudo mdadm /dev/md2 --add /dev/sdc1. This works fine, and mdadm confirms that the device has been re-added as follows: mdadm: re-added /dev/sdc1 After adding the device and allowing the array time to resynch, this is what the output of $ cat /proc/mdstat looks like: Personalities : [raid1] md3 : active raid1 sda4[0] sdb4[1] 244186840 blocks super 1.2 [2/2] [UU] md2 : active raid1 sdc1[0] sdd1[1] 732574464 blocks [2/2] [UU] md1 : active raid1 sda3[0] sdb3[1] 722804416 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 6835520 blocks [2/2] [UU] unused devices: <none> Then after I reboot, this is what the output of $ cat /proc/mdstat looks like: Personalities : [raid1] md3 : active raid1 sda4[0] sdb4[1] 244186840 blocks super 1.2 [2/2] [UU] md2 : active raid1 sdd1[1] 732574464 blocks [2/1] [_U] md1 : active raid1 sda3[0] sdb3[1] 722804416 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 6835520 blocks [2/2] [UU] unused devices: <none> During reboot, here is the output of $ sudo cat /var/log/syslog | grep mdadm : Jun 22 19:00:08 rook mdadm[1709]: RebuildFinished event detected on md device /dev/md2 Jun 22 19:00:08 rook mdadm[1709]: SpareActive event detected on md device /dev/md2, component device /dev/sdc1 Jun 22 19:00:20 rook kernel: [ 7819.446412] mdadm: sending ioctl 1261 to a partition!

  • (Fluent)NHibernate: Mapping an IDictionary<MappedClass, MyEnum>

    - by anthony
    I've found a number of posts about this but none seem to help me directly. Also there seems to be confusion about solutions working or not working during different stages of FluentNHibernate's development. I have the following classes: public class MappedClass { ... } public enum MyEnum { One, Two } public class Foo { ... public virtual IDictionary<MappedClass, MyEnum> Values { get; set; } } My questions are: Will I need a separate (third) table of MyEnum? How can I map the MyEnum type? Should I? What should Foo's mapping look like? I've tried mapping HasMany(x = x.Values).AsMap("MappedClass")... This results in: NHibernate.MappingException : Association references unmapped class: MyEnum

  • Why do I have to specify the -i switch with a backup extension when using ActivePerl?

    - by Zaid
    I cannot get in-place editing Perl one-liners running under ActivePerl to work unless I specify them with a backup extension: C:\> perl -i -ape "splice (@F, 2, 0, q(inserted text)); $_ = qq(@F\n);" file1.txt Can't do inplace edit without backup. The same command with -i.bak or -i.orig works a treat, but also creates an unwanted backup file in the process. Has anyone else faced similar issues? Is there a way around this?

    The following script will delete files in a named directory that are older than 14 days and write to a .txt with the path and the files deleted (found this script on another forum..credit to shay): dir c:\tmp -recurse | where {!$.PsIsContainer -AND $.lastWriteTime -lt (Get-Date).AddDays(-14) } | select LastWriteTime,@{n="Path";e={convert-path $_.PSPath}} | tee c:\oldFiles.txt | Remove-Item -force -whatif I have 3 questions: What is -lt and what is -le and what is -gt? When would I use each one The script above only deletes file...how can I delete folders as well? The script above is based off of LastWriteTime .. what about CreatedDate or LastAccessed time?

  • Get the ID of a Child in a cascade="all" relationship, while adding it to a collection, in Hibernate

    - by Marco
    Hi, i have two Entities, "Parent" and "Child", that are linked through a bidirectional one-to-many relationship with the cascade attribute set to "all". When adding a Child object to the Parent children collection using the code below, i can't get the ID of the persisted child until i commit the transaction: Parent p = (Parent) session.load(Parent.class, pid); Child c = new Child(); p.addChild(c); // "c" hasn't an ID (is always zero) However, when i persist a child entity by explicitly calling the session.save() method, the ID is created and set immediately, even if the transaction hasn't been committed: Child c = new Child(); session.save(c); // "c" has an ID Is there a way to get the ID of the child entity immediately without calling the session.save() method? Thanks

  • How to set up a has-many relationship in Cocoa?

    - by SphereCat1
    I'm building a (very) simple FTP app in Cocoa, and I need to store information on the different types of servers that are supported. So, I've created a ServerType class, which stores all of the relevant information about a single type of server. I then have a ServerTypes class which is designed to manage all of the ServerType classes that are created. My question is how to set up the relationship between the two objects. Is there a preferred method to do so? Also, since Objective-C doesn't support non-instance classes, where should I create an instance of ServerTypes that will have to be used throughout the entire program? Or is there a better way to do that? I need it to be KVC compliant so That I can bind one of the ServerType properties to an NSPopupBox. Sorry about the large volume of questions, I'm fairly new to Cocoa and Objective-C. If you need to see code, just ask and I'll be happy to add some. :) SphereCat1

  • has_one update problem

    - by Kalyan M
    I have two models, User and Account. Each user may have one account. Creating an account for a user works fine. My problem is that when I try to update the account, the previous accounts user_id is nullified and a new account row is created with the user_id. I do not want this happening. I want to update the existing row with the changes to account. How do I do this? Thanks.

  • has_many conditions or proc on foreign key

    - by ere
    I have a has_many association between two models using a date as both the foreign and primary key for each model. It works perfectly one way but not the other. Works has_one :quiz_log, :primary_key => :start_at, :foreign_key => :start_at Doesn't work has_many :event_logs, :primary_key => :start_at, :foreign_key => :start_at The reason being (i think) because the start_at on QuizLog is a date and the start_at on EventLog is a datetime. So it returns nil trying to match the exact datetime on a simple date. How can I cast the foreign_key start_at on the second statement to convert it first from datetime to simply date so it will match the second model?

  • BPA scan did not complete for one or more servers

    In Windows Server 2012 RTM, I am trying to run the BPA. It fails, saying "BPA scan did not complete for one or more servers" Try #1: Try #2: So, I decided to enable the Turn on Script Execution (with Allow all scripts) in Local Group Policy Editor, now I get a very nice exception message :) Clicking on ignore button, BPA logs the following error message: Try #3: So, I decided to go ahead and set the execution policy for all the scopes in PowerShell to unrestricted. Again no luck. What is going on?

  • 3Ware 9650SE RAID-6, two degraded drives, one ECC, rebuild stuck

    - by cswingle
    This morning I came in the office to discover that two of the drives on a RAID-6, 3ware 9650SE controller were marked as degraded and it was rebuilding the array. After getting to about 4%, it got ECC errors on a third drive (this may have happened when I attempted to access the filesystem on this RAID and got I/O errors from the controller). Now I'm in this state: > /c2/u1 show Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ------------------------------------------------------------------------ u1 RAID-6 REBUILDING 4%(A) - - 64K 7450.5 u1-0 DISK OK - - p5 - 931.312 u1-1 DISK OK - - p2 - 931.312 u1-2 DISK OK - - p1 - 931.312 u1-3 DISK OK - - p4 - 931.312 u1-4 DISK OK - - p11 - 931.312 u1-5 DISK DEGRADED - - p6 - 931.312 u1-6 DISK OK - - p7 - 931.312 u1-7 DISK DEGRADED - - p3 - 931.312 u1-8 DISK WARNING - - p9 - 931.312 u1-9 DISK OK - - p10 - 931.312 u1/v0 Volume - - - - - 7450.5 Examining the SMART data on the three drives in question, the two that are DEGRADED are in good shape (PASSED without any Current_Pending_Sector or Offline_Uncorrectable errors), but the drive listed as WARNING has 24 uncorrectable sectors. And, the "rebuild" has been stuck at 4% for ten hours now. So: How do I get it to start actually rebuilding? This particular controller doesn't appear to support /c2/u1 resume rebuild, and the only rebuild command that appears to be an option is one that wants to know what disk to add (/c2/u1 start rebuild disk=<p:-p...> [ignoreECC] according to the help). I have two hot spares in the server, and I'm happy to engage them, but I don't understand what it would do with that information in the current state it's in. Can I pull out the drive that is demonstrably failing (the WARNING drive), when I have two DEGRADED drives in a RAID-6? It seems to me that the best scenario would be for me to pull the WARNING drive and tell it to use one of my hot spares in the rebuild. But won't I kill the thing by pulling a "good" drive in a RAID-6 with two DEGRADED drives? Finally, I've seen reference in other posts to a bad bug in this controller that causes good drives to be marked as bad and that upgrading the firmware may help. Is flashing the firmware a risky operation given the situation? Is it likely to help or hurt wrt the rebuilding-but-stuck-at-4% RAID? Am I experiencing this bug in action? Advice outside the spiritual would be much appreciated. Thanks.

  • Vista install works on one computer, but bluescreens another (on which Vista is known to work)

    - by Ken
    I hope my explanations make some sense -- please ask for clarification if they don't. I had a computer running Windows Vista (Ultimate, 64-bit). All was well! Then one day there was a nasty power surge at the office, and it died. (We didn't have surge protectors at the office, unfortunately. I assumed our lines were conditioned elsewhere, or was not an issue here. Oops.) After some testing, it was determined that the PSU, motherboard, and RAM were bad. While waiting for new hardware to arrive, I put my hard disk in a spare PC which had identical parts (mobo/CPU/RAM/PSU/video). Everything worked perfectly. The only way I could even tell it wasn't my computer is because Vista asked to re-activate itself with the new hardware, which worked fine, too. So the hard disk seems OK. Then the new parts arrived. The old motherboard model is no longer manufactured, so it's a new one with the same CPU/RAM/videocard/etc. slots. The PSU is also new, while the RAM I'm using is from the spare PC mentioned above. When I put it together and tried booting with my old hard disk, it starts to boot Windows, and then (fairly early in the process) gives a bluescreen and immediately reboots (so I can't see whatever the bluescreen is trying to tell me). I tried "safe mode", which also bluescreened. I tried booting the Vista DVD and running the repair utility, which found a Vista install, confirmed that it would not boot, and, eventually, declared that it was unable to repair it. I installed Vista fresh on a new hard disk, with the new mobo/etc., and it works perfectly. (That's what I'm running now.) I've also booted a Linux CD here, which ran great, and I've run Memtest86+ for a while, which found no errors. So all the hardware apart from the old hard disk seems OK, too. I don't think the problem is with my old Vista hard disk, since I used that with another mobo/CPU just fine. I don't think it's any other part of the new hardware, since I'm able to use it (and test it) with no trouble. It's just the combination of my old Vista install plus the new PC hardware that's not happy. I can get my data off my old hard disk and onto my new hard disk, and reinstall my apps, but it would be nice if I could fix things so I could continue to use my old hard disk as before. The latest hypothesis I've heard is that Vista had trouble with the new hardware (i.e., motherboard), but we have no idea what to do about that (except Safe Mode, which didn't work). Suggestions? Hypotheses for what's not right about this combination of Vista install and motherboard? Thanks!

  • Redirect request from https domain to https subdomain with only one certificate

    - by Sean K.
    I'm trying to redirect users to a subdomain in server2 if they make an https request to server1. I only have one certificate, and that's installed on server2. So for instance, from (server1) https://www.example.com to (server2) https://ssl.example.com My best guess is that I will need a certificate for https://www.example.com as the hostname is encrypted inside the HTTP header so my server won't know to redirect until it's decrypted. However, I'm curious if this is possible without two certificates?

  • Samba creates two files on copy of one file

    - by Rudiger
    Hi, I've set up Samba share on a Centos system and all works fine except whenever I copy a file to a share it makes two files, the actual file and what looks to be a log file, which has an appending ._ on the front of it. So for example if I copy index.php it copies that one, plus it creates ._index.php with semi looking log info in it. How do I stop Samba doing this? I'm sure its in smb.conf somewhere but can't find it. Cheers

Update: While some of the settings are stored at HKEY_CURRENT_USER\Software\TortoiseSVN as stated below, there are other settings that are not. Comments seem to indicate these are Subversion specific settings as opposed to TortoiseSVN, but I cannot find where these are located.

  • Linux (Ubuntu 12.04) two gateways one nic

    - by David
    I have Ubuntu 12.04 Server edition Two gateways, both on 192.168.0. network, let's make them 192.168.0.1 and 192.168.0.2 I've read you should be able to add second gateway into /etc/network/interfaces, that it will build out all the routing automatically, but I get "duplicate option" error. So if I have one default gateway, let's say 0.1, and a connection comes through from the 0.2 gateway, my understanding is that it still tries to respond through 0.1 gateway. Can we change this behavior?
