  • Supervisord doesn't stop nginx process

    - by Lennart Regebro
    I'm using Supervisor a lot, and in this project I have an nginx process managed by Supervisord. The relevant parts of the configuration is this: [supervisord] logfile=/home/projects/eceee-web/prod/var/log/supervisord.log logfile_maxbytes=5MB logfile_backups=10 loglevel=info pidfile=/home/projects/eceee-web/prod/var/supervisord.pid ; childlogdir=/home/projects/eceee-web/prod/var/log nodaemon=false ; (start in foreground if true;default false) minfds=1024 ; (min. avail startup file descriptors;default 1024) minprocs=200 ; (min. avail process descriptors;default 200) directory=/home/projects/eceee-web/prod [program:nginx] command = /home/projects/eceee-web/prod/bin/nginx redirect_stderr = true autostart= true autorestart = true directory = /home/projects/eceee-web/prod stdout_logfile = /home/projects/eceee-web/prod/var/log/nginx-stdout.log stderr_logfile = /home/projects/eceee-web/prod/var/log/nginx-stderr.log The /home/projects/eceee-web/prod/bin/nginx command will start nginx in the foreground, it does not deamonify itself. Still, stopping it will fail: supervisorctl stop nginx Will not give any answer, but the process will continue. Any idea what? This is on OS X Darwin, with Supervisor 3.0a9 and nginx 0.7.65.

  • Has anyone managed to build php5-xapian on Ubuntu 12.04?

    - by jetboy
    As Xapian's been dropped from the Ubuntu repositories, I'm attempting to build my own .deb from the instructions here: http://article.gmane.org/gmane.comp.search.xapian.general/8855 http://beeznest.wordpress.com/2011/07/06/howto-build-your-own-binaries-of-php-xapian-bindings-for-debian/ I can only get things to progress beyond the first few seconds by leaving out 'rm debian/control', but if I do, it looks as if the Python and Ruby bindings are building and passing their versions of smoketest correctly. However, the PHP part of the build is failing with this error: /home/charlie/xapian-bindings-1.2.8/php/smoketest.php:38: include(xapian.php): failed to open stream: No such file or directory FAIL: smoketest.php There's a xapian.php file in /home/charlie/xapian-bindings-1.2.8/php/php5/ but if I copy it to /home/charlie/xapian-bindings-1.2.8/php/ or change the path to it in smoketest.php, the build fails right near the start with: dpkg-source: error: aborting due to unexpected upstream changes Unfortunately I'm out of my comfort zone building from source. Anyone got any ideas? Edit post James' answer: Builds fine if I follow instructions exactly. I built it on a test VM initially, but that didn't build the PHP package as PHP itself wasn't installed. Obvious gotcha, but worth mentioning. Installing generated the following error: Setting up php5-xapian (1.2.8-1) ... Processing triggers for libapache2-mod-php5 ... dpkg (subprocess): unable to execute installed post-installation script (/var/lib/dpkg/info/libapache2-mod-php5.postinst): Permission denied ssion denied dpkg: error processing libapache2-mod-php5 (--install): subprocess installed post-installation script returned error exit status 2 Errors were encountered while processing: libapache2-mod-php5 It's only a script for restarting Apache. Stopping Apache before running sudo dpkg -i php5-xapian_*.deb prevents the error. Xapian now shows up in phpinfo(). Job done. Thanks.

  • How to create partition when growing raid5 with mdadm.

    - by hometoast
    I have 4 drives, 2x640GB, and 2x1TB drives. My array is made up of the four 640GB partitions and the beginning of each drive. I want to replace both 640GB with 1TB drives. I understand I need to 1) fail a disk 2) replace with new 3) partition 4) add disk to array My question is, when I create the new partition on the new 1TB drive, do I create a 1TB "Raid Auto Detect" partition? Or do I create another 640GB partition and grow it later? Or perhaps the same question could be worded: after I replace the drives how to I grow the 640GB raid partitions to fill the rest of the 1TB drive? fdisk info: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe3d0900f Device Boot Start End Blocks Id System /dev/sdb1 1 77825 625129281 fd Linux raid autodetect /dev/sdb2 77826 121601 351630720 83 Linux Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc0b23adf Device Boot Start End Blocks Id System /dev/sdc1 1 77825 625129281 fd Linux raid autodetect /dev/sdc2 77826 121601 351630720 83 Linux Disk /dev/sdd: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x582c8b94 Device Boot Start End Blocks Id System /dev/sdd1 1 77825 625129281 fd Linux raid autodetect Disk /dev/sde: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xbc33313a Device Boot Start End Blocks Id System /dev/sde1 1 77825 625129281 fd Linux raid autodetect Disk /dev/md0: 1920.4 GB, 1920396951552 bytes 2 heads, 4 sectors/track, 468846912 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000

  • Intel ICH9/10R raid 5 drive failure

    - by davpen
    About a year ago I was using the native Intel ICH9R Raid 5 an Intel P35 based motherboard. The system was running Vista x64 and when one of the drives failed Vista blue screened on boot until I had figured out which drive had failed and removed it (a rather nerve racking hit and miss affair). The same thing happened some months later on another similar system so it wasn't a once off. This wasn't the robust raid 5 drive failure behavior that I would have hoped for and expected. I moved to Highpoint Rocketraid 2300 and haven't had any problems although I have yet to have a drive fail with this set up. But I am now looking to build a new system based on an i7 and Windows 7. At the moment Highpoint doesn't have drivers for Windows 7 so I am considering moving back to the on board Intel Raid. Yes I know I that I might get away with using the Vista drivers but I don't really want to take that chance with critical data. The question then is has anyone else experienced a drive failure with Intel raid and how did the OS and drivers handle it? Is it safe to go back?

  • Why is my mono/XSP site loading slow?

  • Network Load Balancing, intermittent port problem on Windows Server 2008

    - by Jimmy Chandra
    Trying to troubleshoot an intermittent problem on a Windows Server 2008 NLB. I think it might be related to an NLB issue. We are using Windows Network Load Balancing to balance load for our multiserver SharePoint front ends. Say... Web Front End 1 IP is 192.168.1.100 and Web Front End 2 IP is 192.168.1.101, the NLB is setup to load balance both WFE servers on any incoming traffic to the IP 192.168.1.200. Sometimes we got an intermittent issue where when we try to access the SharePoint site using 192.168.1.200:8080 (say the site is set up to run on port 8080) from a remote client, it will display page not found. Pinging the 192.168.1.200 will give responses, but when trying to telnet to 192.168.1.200:8080 it just won't connect. However, browsing the SharePoint site directly on individual WFE (192.168.1.100 and 192.168.1.101) show no problem whatsoever. My guess also (we didn't get a chance to try it yet, but I think it should work), if I try connecting remotely to individual server, it will respond just fine. But any attempt on trying to connect using the virtual IP (192.168.1.200) will fail miserably. Funny thing is, after a while it will return back to normal. Anyone had similar experience with this type of problem while implementing NLB before? We are doing this in a virtual environment.

  • APC (php accelerator). What situations should I use this?

    - by matthewsteiner
    So I've just got a small vps. I've installed apc, which sped up normal pages by 20% - 30%. I was reading about memcached and came to the conclusion that I can use apc for the same thing (caching objects from database results) if I'm not distributing over other servers. Since I only have the one server, apc will be just as beneficial for caching things in memory. I'm still in development mode, and I'm sure it's hard to tell what would be best for production mode. The thing is, my database queries seem pretty fast (between .0008 and .02). None of my pages are way database intensive. Would it be beneficial to me to cache results in memory? If the database is running well right now, is it going to be having a hard time later? Also, is connecting to the database at all something that costs speed (even if I cache most of my queries, every page has to have a little database interaction for session data). So, basically if I have a limited ram, and one machine, will using apc rather than just letting the database be uncached be much faster? Ideas?

  • Install a KVM guest with LVM partitioning on an LVM partitioned host using virt-install fails, volume group already exists

    - by Rilik84
    our setup consists of a ubuntu 10.04 kvm host server with LVM, on top of which we install the ubuntu 10.04 virtual machines via virt-install and preseed. Each VM has a dedicated logical volume which we pass to virt-install via the "--disk path=/dev/sysvg/vm-name" parameter. The virtual machines themselves are using LVM as well. Virt-install seems to have a few issues with this setup. Say we want to install two virtual machines in parallel. The first vm installs correctly while the second halts during the partitioning, complaining with this error: "volume group name already in use". I tried removing the logical volumes, recreated them, rebooted the kvm host to clear any leftovers but the issue perists. The preseed is telling the vms to create a volume group named "sysvg", which is the same name used by the volume group of the kvm host. Considering this I did another test: I got rid of the preseed part taking care of the partitioning/lvm creation and started the creation of two vms in parallel. If, when prompted, I instruct the vms' installer to do a guided partitioning of the disk with LVM, it will still fail giving this different error on both the vms: Physical Volume /dev/sda5 is already in volume group sysvg. As I wrote, sysvg is the volume group used by the KVM host. So I thought the name clashing was the issue. By removing the preseed part I skipped the volume group naming. I can't understand how the virtual machines would be aware of the presence of that volume group since they're supposed to be isolated from it, especially after I removed and recreated the logical volumes dedicated to them. That detail should not be exposed at all to them! Thanks for the help. I'm clueless.

  • Apple Magic Trackpad 3-Finger Drop Lag

    - by activestylus
    After enabling three-finger dragging for my Trackpad, I notice that it drags well, but when I release there is about 1-2 seconds of lag before it actually drops. I understand this is supposed to be a feature so when you run out of space to drag, you have time to move your hand. But, for those of us powerusers, who move really fast, this is a BUG, not a feature. There should be some way to turn it off! For some perspective, I personally own a Fingerworks trackpad as well (the company Apple bought to make the Trackpad) and it does not suffer this problem. Drops are instantaneous no matter what program I am in. This is hugely frustrating for me, because I thought I was upgrading here and Apple's version does not perform as well as the Fingerworks model (which I purchased in 2004) I actually made a short video illustrating the problem, and why it is so frustrating for anyone who uses the pad as an artistic tool. Anyone here face this problem? If not, how would you recommend that I address Apple directly about this? PS - Already looked at this thread and the conclusion does not help me. I do not have one-finger drag enabled. PPS - I understand that for most people this is not an issue because they use the 'click' feature of the Trackpad. However, after years of using Fingerworks and not having to click ever, I find that it slows me down.

  • How do I ensure a process is running, even if it kills itself? (it needs to be restarted then)

    - by le_me
    I'm using linux. I want a process (an irc bot) to run every time I start the computer. But I've got a problem: The network is bad and it disconnects often, so I need to manually restart the bot a few times a day. How do I automate that? Additional information: The bot creates a pid file, called bot.pid The bot reconnects itself, but only a few times. The network is too bad, so the bot kills itself sometimes because it gets no response. What I do currently (aka my approach ;) ) I have a cron job executing startbot.rb every 5 minutes. (The script itself is in the same directory as the bot) The script: #!/usr/bin/ruby require 'fileutils' if File.exists?(File.expand_path('tmp/bot.pid')) @pid = File.read(File.expand_path('tmp/bot.pid')).chomp!.to_i begin raise "ouch" if Process.kill(0, @pid) != 1 rescue puts "Removing abandoned pid file" FileUtils.rm(File.expand_path('tmp/bot.pid')) puts "Starting the bot!" Kernel.exec(File.expand_path('./bot.rb')) else puts "Bot up and running!" end else puts "Starting the bot!" Kernel.exec(File.expand_path('./bot.rb')) end What this does: It checks if the pid file exists, if that's true it checks if kill -s 0 BOT_PID == 1 (if the bot's running) and starts the bot if one of the two checks fail/are not true. My approach seems to be quite dirty so how do I do it better?

  • Errors in Homebrew on OS X Lion

  • Backup Exec 10 - Network connection to the remote agent has been lost

    - by jherlitz
    Okay, so I have 4 remote offices, all running off of a 3mb ethernet connection. Two sites are part of a WAN and 2 sites are using 3mb connections over a site to site tunnel. I am using Backup Exec 2010, I have the remote agent installed on all the remote servers. For the past few weeks now, on the two sites running over the site to site tunnel have been failing with the following error message now. "The network connection to the Backup Exec Remote Agent has been lost. Check for network errors" We used to be on a DSL connection site to site tunnel, now we changed to the 3mb ethernet connection using site to site tunnel. I have to find out, has it been failing ever since we changed, or just recently. Backup exec support is telling me it is a network issue. My communication or connection to the server is solid, we don't have any issues, or outages. So I am baffled on why this continues to fail. And why just those two sites.. Any advice?

  • High load average due to high system cpu load (%sys)

    - by Nick
    We have server with high traffic website. Recently we moved from 2 x 4 core server (8 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 5.x, to 2 x 4 core server (16 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 6.3 Server running nginx as a proxy, mysql server and sphinx-search. Traffic is high, but mysql and sphinx-search databases are relatively small, and usually everything works blazing fast. Today server experienced load average of 100++. Looking at top and sar, we noticed that (%sys) is very high - 50 to 70%. Disk utilization was less 1%. We tried to reboot, but problem existed after the reboot. At any moment server had at least 3-4 GB free RAM. Only message shown by dmesg was "possible SYN flooding on port 80. Sending cookies.". Here is snippet of sar 11:00:01 CPU %user %nice %system %iowait %steal %idle 11:10:01 all 21.60 0.00 66.38 0.03 0.00 11.99 We know that this is traffic issue, but we do not know how to proceed future and where to check for solution. Is there a way we can find where exactly those "66.38%" are used. Any suggestions would be appreciated.

  • Do any well-known CAs issue Elliptic Curve certificates?

    - by erickson
    Background I've seen that Comodo has an elliptic curve root ("COMODO ECC Certification Authority"), but I don't see mention of EC certificates on their web site. Does Certicom have intellectual property rights that prevent other issuers from offering EC certificates? Does a widely-used browser fail to support ECC? Is ECC a bad fit for traditional PKI use like web server authentication? Or is there just no demand for it? I'm interested in switching to elliptic curve because of the NSA Suite B recommendation. But it doesn't seem practical for many applications. Bounty Criteria To claim the bounty, an answer must provide a link to a page or pages at a well-known CA's website that describes the ECC certificate options they offer, prices, and how to purchase one. In this context, "well-known" means that the proper root certificate must be included by default in Firefox 3.5 and IE 8. If multiple qualifying answers are provided (one can hope!), the one with the cheapest certificate from a ubiquitous CA will win the bounty. If that doesn't eliminate any ties (still hoping!), I'll have to choose an answer at my discretion. Remember, someone always claims at least half of the bounty, so please give it a shot even if you don't have all the answers.

  • Fix Video timelines

    - by Josh
    So, I have been going through and riping all of my DVD's and it seems that the way to get the highest quality out of these is to have DVD Shrink de-encrypt, rip, and decompress, the DVD's. After that I usually end up with a high quality (high size) set of .vob files in a classic DVD structure. Then I use a python script that I wrote to automate the process of finding the title sequence and then combining all of the title sequences' .vob files together into one file(similar to the "copy /b" command in windows), and then changing the extension to .mpg (a more widely supported format then .vob). This allows me to get a high quality rip in about 40 min. The problem comes in playing the files. I need all of the ripped dvd's to play on my media computer using windows media center but windows media center (and vlc for that matter) all think that the video files are anywhere from 5 min. to 0 min. which is not a problem (the video will still play all the way through) but if you want to pause it, when it is unpaused the video will start all the way over (Also fast forward and rewind don't work). I suspect that it is something wrong with the way the timeline is encoded in the video file, various forums on the internet recommended using virtualdub to fix the errors. But when I try to open the file virtual dub says that the file is not in mpeg-1 encoding and may be in mpeg-2. Is there any way to fix this? PS: I am aware that there was a similar question but it hasn't had any activity for 2 months and is dealing more with wmv files.

  • Redis as substitution for Memcache

    - by Boban P.
    We have distributed web app, and for now, as session handler, we use two separate instances of memcache in redundancy, so everything that is written in one memcache is also written in other. Memcache is fairly easy to install, use, and maintain but we have one problem: if one memcache fail, everything is fine, php comunicate with other instance which has all data (although, half of connections have a delay because they try to use failed one, wait a little, and then contact other memcache). When failed instance comes back to life again, it starts up empty. If established session request data from that instance, session fails, and user logs out, and that happens to half of users.So, we are thinking about to switch to redis for session handling, and maybe keep memcache for cache only. My questions are: If we setup redis instances as master-slave, and if master fails, can sentinel promote slave as new master and when old master comes back to life, will it stay as slave or not? Is redis call malloc at startup to allocate part of memory, like memcache or varnish, or it calls malloc for every key inserted? And what are pros and cons of that?

  • What steps to take when CPAN installation fails?

    - by pythonic metaphor

  • Getting Dell E6320 with I7 to work with 3 monitors at 1920x1080p x 3

    - by MadBoy
    I want to buy Dell E6320 which comes with Intel Core I7-2620M (2.70GHz, 4MB cache, Dual Core) with Intel HD Graphics 3000. Laptop will come with docking station. I want to connect 3 monitors to that docking station so that working at home would give me some additional boost. Docking station will allow me to connect only 2 monitors so I'm looking at following other options: Matrox TRIPLEHEAD2GO DIGITAL Edition or TRIPLEHEAD2GO DP Edition. But reading Matrox Support Page intel GPU can't run the highest resolution with 3 monitors connected, it even gets worse since it seems monitors would have to be able to work at 50hz. Also I'm not sure but it seems that Matrox doesn't split the monitors as 3 separate monitors but simply as one big space (which is a bit opposite to what I need) Buy 2 or maybe just 1 USB based monitor but it would also mean having 1 or 2 different monitors then the main one, unless I buy 3 USB based monitors which would mean more money to spend. Also I found only couple of models and most of them require USB 3.0 and no other cables to plug in (nice but costly - couldn't find decent monitor with only USB for sending signal and having power connected normally) . But docking station has only one USB 3.0 port. Can I use hub and still get it to work? Find some converters from Digital to USB (I think DisplayLink does some?) Buy different laptop but what kind? I need it to be I7, small (13"), fast and lightweight. At same time it requires docking station that I can use at home to connect 3 external monitors. Some other suggested solution... Edit: I need 3 monitors for work in terms of coding in Visual Studio or having word/excel/outlook open. Nothing fancy. Maybe some movie once in a while.

  • Time Drift on VM servers, need a reliable solution

    - by zeroasterisk
    We have some windows server 2008 VMware instances on multiple physical servers (hosted) and an application which requires the time to be synced across the server instances. Obviously, VMware has problems with this and we really have never gotten it working any better, we have setup the servers to poll for an NTP update every minute which mitigates the problem (in a fairly crude way). Except that every once in a while, the update will fail (because there's already too much drift) and then windows never does an NTP update afterwards which eventually allows the servers to drift far enough apart that our application breaks, and we notice. We are thinking about changing hosts to Xen servers on approximately the same setup, and I anticipate similar problems. can anyone tell me if Xen has the same time-drift issues VMware does, for guests? can anyone tell me what the best windows server settings are for syncing with an external NTP server to keep things in sync: how frequently do you recommend syncing? (assuming every minute) do you recommend running our own NTP server - even if it has to be on a virtual instance? (assuming not) is there any way to tell windows to sync with the NTP server no matter what the time difference is? any other suggestions for keeping windows servers time in sync? I have become familiar with [ http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1318 ] and it's helped, but it's not been totally effective (see above). thanks much!

  • Get Illegal Instruction error when booting Linux in VirtualBox, works fine when booted directly

    - by rkjnsn
    I have a computer on which I am dual booting Windows 7 and Gentoo Linux (both 64-bit). I want to be able to load up my Linux installation in a VM while I am booted into Windows. I have installed VirtualBox and followed the instructions for creating a raw disk VMDK. When I start the VM, Linux starts booting, but then fails with the following error when unlocking my root partition: truecrypt[441] trap invalid opcode ip:373615538e0 sp:3dd0e0dfb60 error:0 in libpixman-1.so.0[373614d6000+8d000] Everything works fine when I boot into Linux directly. What could cause an illegal instruction to be hit in libpixman only when booting in VirtualBox? Update: As a troubleshooting step, I recompiled pixman without "-march", and no longer get an illegal instruction error in that library. (The boot fails in the same spot with the same error in a different library, however.) How can I determine the specific opcode that isn't working in VirtualBox so I can disable it in my CFLAGS without having to disable all CPU-specific optimizations? I am still confused as to why there would be any user-mode instruction that would fail to work in a VM. Is this a known limitation? My CPU is an Intel Core i7 3720QM, and I have hardware virtualization support enabled.

  • How do I fix a super slow MacBook?

    - by MakingScienceFictionFact
    I'm running a black MacBook 4.1. Intel Core 2 Duo @ 2.4 GHz, 2 GB RAM, 250 GB hard disk drive, bus speed is 800 MHz. It's about three years old in excellent shape externally. I treat this thing like a baby. It used to run awesome, but now it's super slow at everything. I get the spinning pizza of death constantly. It takes a long time to boot up or load any program, even Safari and iTunes. iPhoto is terribly slow. The Internet doesn't work properly and it reminds me of a buggy PC. I've formatted it and re-installed Mac OS X 10.6 (with all updates), and I've done the disk repairs process. As an iOS developer this is driving me crazy, but luckily I have an iMac to work on in the day which is fast. I'm ready to format it again, but that didn't work last time. After the last format, I copied back files from an external drive so maybe the offending files were hidden in there somewhere. Here are the hard disk drive and RAM specifications. It is upgrade-able to 4 GB of RAM. Hard disk drive: The Fujitsu Mobile MHY2250BH is a 250 GB, standard hard disk drive. Its burst transfer rate is 150 Mbyte/s. This is a 5400 RPM drive and comes with an 8 MB buffer. RAM: two sticks of 1 GB DDR2 SDRAM, speed: 667 MHz.

  • How to grant read/write to specific user in any existent or future subdirectory of a given directory? [migrated]

    - by Samuel Rossille
    I'm a complete newbie in system administration and I'm doing this as a hobby. I host my own git repository on a VPS. Let's say my user is john. I'm using the ssh protocol to access my git repository, so my url is something like ssh://[email protected]/path/to/git/myrepo/. Root is the owner of everything that's under /path/to/git I'm attempting to give read/write access to john to everything which is under /path/to/git/myrepo I've tried both chmod and setfacl to control access, but both fail the same way: they apply rights recursively (with the right options) to all the current existing subdirectories of /path/to/git/myrepo, but as soon as a new directory is created, my user can not write in the new directory. I know that there are hooks in git that would allow me to reapply the rights after each commit, but I'm starting to think that i'm going the wrong way because this seems too complicated for a very basic purpose. Q: How should I setup my right to give rw access to john to anything under /path/to/git/myrepo and make it resilient to tree structure change ? Q2: If I should take a step back change the general approach, please tell me.
