• Linux halts every few seconds

  - by Zeppomedio

  We're having an issue where one our Linux boxes (Ubuntu 10.04 LTS, running on EC2 with a quadruple-large size, 68GB of RAM and 8 virtual cores with 3.25GHz each) freezes up every few seconds. Typing in an ssh session will freeze, and running strace on one of the Postgresql processes that's running usually shows: 02:37:41.567990 semop(7831581, {{3, -1, 0}}, 1 for a few seconds before it proceeds (it always gets stuck at that semop). OProfile shows that most of the time is spent in the kernel (60%) versus 37% in Postgresql. The result of these halts (which began suddenly a day ago) is that load on the box has gone from 0.7 to 10+, and causes our entire stack to slow done. Any ideas on how to track down what's going on? iostat doesn't show the disks being particularly slow or overloaded, and top shows user cpu % spike from 8% to about 40% whenever these back-ups happen.

• Keeps "SSH timeout" error in our AWS instance- how do i diagnose?

  - by ming yeow

  I am befuddled by this error. We keep failing to SSH into our AWS instance, whether it is is deployment or via console. I have tried rebooting a few times, but it does not seem to be helping. Here are a couple of error messages i keep getting. connection failed for: HOST.NAME.amazonaws.com (Errno::ETIMEDOUT: Operation timed out - connect(2)) 111.222.333.444: ssh connection failed at 2010-07-02 03:39:37 I also SSHed in when it was up, and monitored "top" when ssh times out. looking at the memory logs, it does not look like any program was hogging

• Create an AWS HVM Linux AMI from an Existing Paravirtual Linux AMI

  - by javacavaj

  Is it possible to create a hardware virtual machine (HVM) AMI from an existing paravirtual (PV) AMI. My initially thought was to start a new PV instance and use the ec2-create-image command to create a new image while specifying HVM as the virutalization type. However, ec2-create-image does not have a command line parameter to specify the virtualization type. Is there another way to go about doing this?

• java.lang.OutOfMemoryError on ec2 machine

  - by vinchan

  I have a java app on a large instance that will spawn up to 800 threads. I can run the application fine as user "root" but not as another user which I created. I get the deadly. java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:657) at java.util.concurrent.ThreadPoolExecutor.addWorker(ThreadPoolExecutor.java:943) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1325) nightmare. I have tried increasing the stack size already in limits.conf to no avail. Please, help me out. What is different here for the root and other user?

• AWS EC2 can't execute user-data script

  - by Bloodnut

  I'm pretty new to AWS and EC2 but I want to run instances with a user script after it's booted from another instance. I have installed ec2 tools and ran the command as it's explained in various examples like here http://www.turnkeylinux.org/blog/ec2-userdata and Eric Hammond's tutorials. however when I actually use the command: "ec2-run-instances --key my-key --user-data-file myscript my-ami" it only runs the new instance but doesn't execute the script myscript contains: #!/bin/bash echo "hello" ~/output.txt I'm running ubuntu server 12.04 AMIs. the target AMIs are duplicates of the initiating instance. if I run curl http:// 169.254.169.254/latest/user-data the imported script is there.

• AWS forwarding email to a gmail account

  - by user2433617

  So I registered a domain name. I then set up a static webpage using aws (S3 and Rout53). Now what I want to do is forward any email I get from that custom domain name to a personal email address I have set up. I can't seem to figure out how to do this. I have these record sets already: A NS SOA CNAME I believe I have to set up an MX record but not sure how. say I have the custom domain [email protected] and I want to redirect all email to [email protected]. The personal email account is a gmail (google accounts) email address. Thanks.

• How can I do an SELINUX filesystem relabel without rebooting first?

  - by Skaperen

  I can touch the file /.autorelabel and reboot and during the initialization coming back up it will do the SELINUX relabel for me. But I want to do this in a different situation where the system has just been copied to a hard drive image. I can chroot to the originating file tree, or chroot to the just populated device image and run it. I just can't find anything that says what to be run. This image is being made into an AMI on AWS EC2, and contains CentOS 6.3. But the time it takes to relabel is too long (6 minutes or more). I want to move the relabel to the image build where the extra time is not an issue (because it happens once instead of every time an AMI is launched). I can make this relabel be the very last thing just before the filesystem is unmounted for the last time until it becomes an AMI and will launch. I just need to know what to call to do it. I have searched man pages with no luck. I have searched system init scripts but where /.autorelabel is detected, it is unclear what is happening. Documents like http://www.centos.org/docs/5/html/5.2/Deployment_Guide/sec-sel-fsrelabel.html only tell how to do things that still really do the work after a reboot. I need to have the work doing BEFORE the "reboot" (unmount, build AMI, and launch ready to go). The big point is ... yes there will be a reboot ... but I want the relabel work to be done before that so it won't be done every time an AMI is launched (because it takes so long).

• Good/Better config for MySQL on an EC2 Large Instance

  - by Tim Reynolds

  I have an EC2 Large instance dedicated to MySQL. It will be serving a Joomla/Magento combo so it has a blend of InnoDB and MyISAM tables. I have only worked with MyISAM in the past and am therefore unfamiliar with the settings InnoDB uses. Experiments so far have been less than fruitful, as I keep causing the InnoDB engine to be disabled. My instance is running Ubuntu 10.04 64 bit server edition and has ~7.5G of ram. MySQL is currently using ~0.6% of that, with somewhat poor performance. I would like to configure it to use as much of the system RAM as is reasonable. Testing some settings I learned that the InnoDB logs can't collectively be larger than 4G. Would anyone be able to provide some base InnoDB and MyISAM settings to get my started. Thank you Tim

• EC2 custom topology

  - by Methos

  Is there any way to create a desired topology of EC2 instances? For example, can I create a 3 node topology of nodes A, B, C where C gets the public IP address and B and A are connected to it. Something like: Internet <-- C <-- B <-- A B and A only get private IP addresses and there is no way for the traffic to reach A before hitting B and C. This means I can install whatever I want to install on C and B to filter, cache etc. I'm going through EC2 documentation but so far I have not seen anything that talks about it. I will really appreciate if anyone knows how to do this on EC2

• How can I poll different aws sqs in the same process?

  - by Luccas

  What is the right way to poll from differents AWS SQS in the same process? Suppose I have a ruby script: listen_queues.rb and run it. Should I need to create threads to wrap each SQS poll or start sub processes? t1 = Thread.new do queue1.poll do |msg| .... end t2 = Thread.new do queue2.poll do |msg| .... end t2.join I tried this code, but the poll is not receiving any of the messages available. When I run only one of them (t1 or t2), it works. But I need the 2 running. What is going on? Thanks!!

• Can I use nginx to start EC2 instances on demand?

  - by Gabe Hollombe

  TL;DR - Is there a way to make nginx act as an elastic load balancer that will spin up EC2 instances on demand, allowing for the case when periods of no demand mean no instances will be running? Longer explanation - I have an nginx server that proxy_pass'es requests to a server on EC2. This server doesn't get many requests, so I'd like to keep the server spun down during periods of inactivity (I already have a script to do this). Then, when the instance is spun down and nginx gets a request for that instance, it will time out when trying to get a response from it. At this point, can I somehow trigger a shell command on the server to use EC2's command line tools to spin up the instance, then re-try the user's request after it has started?

• How do you create large, growable, shared filesystems on Linux at AWS?

  - by Reece

  What are acceptable/reasonable/best ways to provide large, growable, shared storage at AWS, exposed as a single filesystem? We're currently making 1TB EBS volumes ~biweekly and NFS exporting with no_subtree_check and nohide. In this setup, distinct exports appear under a single mount on the client. This arrangement does not scale well. The options we've considered: LVM2 with ext4. resize2fs is too slow. Btrfs on Linux. not obviously ready for prime time yet. ZFS on Linux. not obviously ready for prime time yet (although LLNL uses it) ZFS on Solaris. future of this combo is uncertain (to me), and new OS in the mix glusterfs. heard mostly good but two scary (and maybe old?) stories. The ideal solution would provide sharing, a single fs view, easy expandability, snapshots, and replication. Thanks for sharing ideas and experience.

• EC2 instance store cloning or to ebs via gui management console

  - by devnull

  I have found similar questions here but the answer are either outdated or are from the command line. The case is this. I have an EC2 instance using instance store (this was the only AMI available for Debian 6 in Ireland). Now through the AWS GUI I can do a snapshot of the instance volume and/or even create a volume. But an image made from the snapshot doesn't boot. What is the best solution to either clone an EC2 instance that uses instance store OR from the created snapshot of the instance store to launch a new EBS instance (identical clone) FROM the gui aws management console and not command line ? Before turning this down consider that there is not similar question on how to do it via the aws management console. hint can't be done is not an appropriate answer. As you can create a snapshot of the instance store backed instance and/or a volume and create an AMI from that snapshot.

• What ports to open in aws security group for aws?

  - by HarrisonJackson

  I am building the backend for a turn based gamed. My experience is mostly with a lamp stack; I've dabbled in nginx on a node side project. I just read Scaling PHP Applications by Stephen Corona of Twit Pic. He recommends an nginx server over apache. He says that his ubuntu machine has 32768-61000 ports open. On AWS do I need to modify my security to group to allow access to those ports? How do I ensure nginx is taking full advantage of this configuration?

• Intermittent 404 on select assets, LAMP stack

  - by Tom Lagier

  We have a LAMP stack WordPress server that is serving most assets correctly. However, one plugin's CSS file and several images are returning soft 404s roughly 20% of the time. I can't find any reference to the 404 in the access logs, but the browser is definitely receiving a 404 response from somewhere (WordPress, I would assume). When I use an alias URL that does not match the site URL but does resolve to the asset path, the resource loads correctly 100% of the time. However, using the site url only resolves for the select, problematic assets 20% of the time. You can test one of the problematic assets here: http://www.mreco.org/wp-content/uploads/2014/05/zero-cost.jpg However the alias link always resolves correctly: http://mr-eco.wordpress.promocampaigns.com/wp-content/uploads/2014/05/zero-cost.jpg Stranger, if I attempt to access outdated content that definitely does not exist on the server, at the live URL it returns the content roughly 50% of the time. Using the alias link, it 404s 100% of the time - the correct behavior. Error log and PHP error log are clean. A sample access log (pulled from grep 'zero-cost.jpg' /var/log/httpd/mr-eco-access_log) from several refreshes of the live direct link (where I am not seeing any 404's): 10.166.202.202 - - [28/May/2014:20:27:41 +0000] "GET /wp-content/uploads/2014/05/zero-cost.jpg HTTP/1.1" 304 - 10.166.202.202 - - [28/May/2014:20:27:42 +0000] "GET /wp-content/uploads/2014/05/zero-cost.jpg HTTP/1.1" 304 - 10.166.202.202 - - [28/May/2014:20:27:43 +0000] "GET /wp-content/uploads/2014/05/zero-cost.jpg HTTP/1.1" 304 - 10.166.202.202 - - [28/May/2014:20:27:43 +0000] "GET /wp-content/uploads/2014/05/zero-cost.jpg HTTP/1.1" 304 - 10.176.201.37 - - [28/May/2014:20:27:56 +0000] "GET /wp-content/uploads/2014/05/zero-cost.jpg HTTP/1.1" 200 57027 Chrome's dev tools list the following network activity before displaying 404 page content: zero-cost.jpg /wp-content/uploads/2014/05 GET 404 Not Found text/html Other 15.9?KB 73.2?KB 953?ms 947?ms My Apache configuration is standard, I've listed the virtual host entry and .htaccess file below.

In the past, inconsistently 404ing assets have been because of out-of-sync instances behind a load balancer. In this case, it is a single instance behind the load balancer. Because of the inconsistency, it feels like a caching issue. We don't make use of Apache caching, and as far as I know WordPress should not be caching either. What I've done so far: Reset WordPress permalinks Disabled WordPress plugins Re-generated WordPress .htaccess file Swapped ServerName and ServerAlias directives Cleared browser cache Confirmed disk location of resources Checked PHP, access, and error logs Confirmed correct DNS setup (can post if necessary) I'm at a total loss. Thanks for helping me out!

• Should EC2 server self register or have admin server

  - by hortitude

  I'm creating AWS servers using chef. I am also planning on enabling auto-scaling. While we have automatic monitoring setup already (server density or nagios etc), I was also going to setup the cloud watch alarm for the status check on the server. This led me down the path of trying to decide whether to install the ec2-command-line tools on the server itself (which then requires me to install java on the servers -- despite no other need for Java in our environment) or to possible have an "admin" box that will check periodically for servers and make sure they have their alarms set. I expect this paradigm to carry over to other things we want to configure (perhaps ensuring that termination protection is setup on production servers?). Any thoughts as to why to go one direction or another?

• Does cloud storage replicate the data over many datacenters if so it means i benefit content delive

  Let's assume that i want to use cloud storage service from one of the cloud storage provider, i got X gb structured and unstructured data and i will use this data as my contents of my interactive web page. And now i have some doubts about this point.I have many users and they are all visiting my web page from various countries.To be more specific first; does my data stored only of the Cloud Storage data center ? or Does my data replicated over many data centers of my provider? second if so; how can i benefit from content delivery network? (matching and placing users’ content nearest storage data centers)

• How can I automatically cycle a new image in an AWS Auto Scaling Group?

  - by JustinY

  I have a web application setup with a load balancer and auto scaling group to manage scaling. The source code is in a git repository so I don't have to update the images when the code changes, but occasionally the environment changes so we create a new image. Then that image needs to be cycled into the auto scaling group. Is there a way to cycle the images automatically? Right now I schedule a scale up and scale down action which gets rid of the old instances.

• How do I handle mysql replication in EC2 using private IPs?

  - by chris

  I am trying to set up a mysql master/slave configuration in two EC2 instances. However, every time I reboot an instance, the IP address (and hostname) changes. I could assign an Elastic IP address, but would prefer to use the internal IP address. I can't be the first person to do this, but I can't seem to find a solution. There are a lot of "getting started" guides, but none of them mention how to handle changing IP addresses. So what are the best practices to manage master/slave replication in EC2?

• Choosing between cloud (Cloudfoundry ) and virtual servers - for developers

  - by Mike Z

  I just came across some articles on how to setup your own cloud using Cloudfoundry and Ubuntu, this got me thinking, choosing our infrastructure, if we want to use our own servers what's the advantage of cloud on virtual servers vs just using virtual servers, VPN? If we now develop for the cloud later if we need help we can quickly move on to a cloud provider, but other than that what's the advantage and disadvantage of private cloud in these areas? speed of development, testing, deployment server management security having an extra layer (cloud) will that have a hit on server performance, how big? any other advantage/disadvantage?

• AWS Autoscaling issue with existing nodes in ELB

  - by Ram Prasad

  I already have a ELB setup called MyLoadBalancer. I already have 2 nodes running on it with health checks (that checks a URL on the node to see if they are up) Created an autoscaling group (min 2, Max 10) Associated launchconfig mylaunchconfig that provisions a node using an AMI Created a trigger, that checks for avg min connections of 100 and Max of 500 (checks the load balancer and it is support to increase the node count by 1, if avg connections are 500 and decrease by one if less than 100) as-create-or-update-trigger MyTrigger --auto-scaling-group MyAutoScalingGroup --namespace "AWS/ELB" --measure RequestCount --statistic Average --dimensions "LoadBalancerName=MyLoadBalancer" --period 60 --lower-threshold 500 --upper-threshold 800 --lower-breach-increment=-1 --upper-breach-increment=1 --breach-duration 600 Now the issue is, as soon as I put in the trigger, it start 2 nodes .... but there are already two nodes in the LB. So, why is it provisioning 2 more nodes, when the nodes are there ? is it because it is not recognizing the existing 2 nodes ? then how do I add the existing nodes to the AutoScaling group ?
