  • Amazon EC2 firewall rules & VPN connections

    - by John
    I'm moving from Rackspace to Amazon EC2. One thing I like about our Rackspace setup is that it is extremely secure. The MySQL box can only be accessed via internal IPs, and we have a Cisco VPN firewall that allows us to dial in remotely and access port 3306 as though we were on the internal network. I'd like to figure out how to replicate this setup with EC2. How can I make the MySQL box so that port 3306 can only be accessed on the internal network? What about the VPN piece of things? I know Amazon has the VPC service, but it seems like that's for the purpose of connecting to an existing network. I don't have an existing network. I want to essentially create one inside Amazon and connect to that. What are my options? Any good tutorials on how to get started? Thanks in advance for your help

  • FFMPEG Install on EC2 - Amazon Linux

    - by Oliver Holmberg
    Hello Serverfault friends, I am about two days into attempting to install FFMPEG with dependencies on an AWS EC2 instance running the Amazon Linux AMI. I've installed FFMPEG on Ubuntu and Fedora systems with no problems in the past, and have read reportedly successful instructions on installing on Red Hat/Fedora. I have followed a number of tutorials and forum articles to do so, but have had no luck yet. As far as I can tell, the main problems are as followed: The amazon linux (Most similar to red-hat/centos) yum repositories don't have ffmpeg available. I have found instructions to update the repositories to include the required packages, but adding these repositories cause yum to fail in updating packages. (Also, I've read some cautionary tales about adding redhat/centos repositories to amazon linux that lead me to believe it may be a bad idea) (https://forums.aws.amazon.com/thread.jspa?messageID=229166) I have tried a more complicated method of downloading the source tarball, compiling, and installing, but this always fails due to missing dependencies and other errors. On to my question: Has anyone successfully installed FFMPEG on Amazon Linux? Is there a fundamental incompatibility? If anyone could share specific instructions on installing ffmpeg on amazon linux I would be greatly appreciative. Any other insights/experiences would also be appreciated. Thanks in advance, Oliver

  • Hadoop on Amazon EC2 : Job tracker not starting properly

    - by Algorist
    Hi, We are running Hadoop on Amazon EC2 cluster. We start the master, slaves and attach the ebs volumes and finally waiting for hadoop jobtracker, tasktracker etc to start and we have timeout of 3600 seconds. We are noticing 50% of the time that job tracker is not able to start before the timeout. Reason being, hdfs is not initialized properly and still in safemode and job tracker is unable to start. I noticed few connectivity issues between nodes on EC2 as I tried manually pinging slaves. Did anyone face similar issue and know how to solve this? Thank you Bala

  • Amazon EC2 Creating Tunnel with OpenVPN

    - by nocode
    I have followed these instructions: http://aws.amazon.com/articles/0639686206802544 I can ping the VPN endpoints and I have the corresponding VPC CIDR pointing to the EC2 instance in the route table. Here is my config: port 1194 proto udp dev tun # Remote peer and network remote Elastic_IP route 10.0.0.0/16 # Configure local and remote VPN endpoints ifconfig 169.254.255.1 169.254.255.2 # The pre-shared static key secret /etc/openvpn/ovpn.key keepalive 10 120 persist-key persist-tun log /var/log/openvpn.log verb 3 When I look at my logs, I get this error: RESOLVE: Cannot resolve host address: 10.0.0.0/16: Name or service not known OpenVPN ROUTE: failed to parse/resolve route for host/network: 10.0.0.0/16 in VPC1, the CIDR is 172.31.0.0/16 which is targeting the EC2 instance also running OpenVPN. I'm getting the same error from the Instance in VPC2 with the corresponding CIDR. Just for testing, i stopped the IPTABLES service I am running the Amazon linux AMI image (x64) as specified in the article I linked.

  • What is the difference between a plain Amazon ec2 instance and beanstalk?

    - by Alex Ford
    I am a solo developer and the sites I'm deploying are very small, usually hobby sites and I have a few questions about the Amazon services. Is there a reason for me to use beanstalk or should I just stick with a single ec2 instance? Should I use RDS for database? I heard someone say that I could just install a database on my ec2 instance, making it cheaper. I'm trying to keep everything as cheap as possible. I need to point custom domains to my sites. Pretty sure that means I have to deal with elastic IPs. Do those work with beanstalk or only with individual ec2 instances? Thanks in advance!

  • NAT and NGINX on the same server

    - by Morten
    I'm setting up a VPC cluster for my collaborative todo list application www.getdoneapp.com. To have my servers on the private network I need a NAT server so my servers on the private network can connect to the internet to receive updates and what not. The NAT server will consume an elastic IP address, so I'm wondering if I can just have that NAT server run nginx to direct traffic to my internal servers for HTTP. So the question is, is it a bad idea to run NGINX and NAT on the same server, or should I go for consuming 2 elastic IP addresses?

  • Amazon EC2 instance was not available for few minutes (amazon showed that everything ok)

    - by Salvador Dali
    Few minutes ago my amazon Ec2 instance was unavailable for a few minutes. During this time neither I was able to connect to web-site with http, nor I was able to ssh to it. Also I was not able to connect to my amazon management console for some time (less than amount of unavailability of my instance). When I was able to connect to management console, it was showing me that everything is running smoothly (but I still was not able to connect to instance in any way for a minute or two). During this time I have checked their status page just to see that there is no issues (my instance is in Ireland and there is nothing wrong there today). After that I was able to log in. I checked my logins with last to see that no one except me was logging in. I also looked in apache logs and there was no errors or warnings during this time. Right now when I see my amazon monitor, I see a small spike in CPU in last 15 minutes (but this is from 10% to like 20%) I have no idea what can it be (I have never experienced anything like this before) and therefore I have no idea how scared should I be or what else should I look for. Can anyone give me a hint what my actions should be in such situation?

  • Setup of high-end web server and DB server cluster on Amazon EC2: Is this how it's done?

    - by user1086584
    Amazon is so technical, I want to confirm that my understanding is correct. We have a large 500 GB database. (OrientDB.) We will have it mirrored to one another in the same Availability Zone. We believe the database size will grow rapidly. The plan is: Get 4 large instances that are compatible types with Placement Groups (as well as ideally, Enhanced Networking) (2 for web, 2 for DB.) We use an EBS-backed instances to store our operating system. Discussion here: http://alestic.com/2012/01/ec2-ebs-boot-recommended We can set up ephemeral SSD instance storage as swap space. (But it is lost after even a reboot. I hear its hard to add ephemeral storage if booting from EBS, but possible.) For offsite backup, we will take periodic snapshots and store them on S3. Obviously we need to ensure the database is in a safe state when that snapshot happens to avoid corruption. (Any hints here, aside from shutting down the DB?) If the database gets too big, we need to create a EBS volume that's larger. We can use RAID to break the 1 TB limit: http://alestic.com/2009/06/ec2-ebs-raid Static assets on web servers will be stored on S3. Is that correct? Or am I missing something?

  • How do you get AWS VPC EC2 instances to be able to see the AWS APIs?

    - by Peter Mounce
    We're spinning up infrastructure inside of an AWS VPC via CloudFormation. We're using auto-scaling groups to bring up VPC-EC2 instances (so, we don't bring up instances directly; ASGs manage that). Inside of a PVC, EC2 instances only have a private IP; they cannot see the outside world without further work. When these instances spin up, we have some bootstrap tasks that require talking to the various AWS APIs. We also have some ongoing tasks that require AWS API traffic. How are you tackling this apparent chicken-egg problem? We've read about: NAT instances - but don't like this so much because it's another layer to our stack. assigning elastic-IPs to each VPC instance that needs to talk - but a) they all do, and b) since we're using ASGs, we don't know which instances to assign EIPs to at provision-time, and c) we'd need to set up something to monitor those ASGs and assign EIPs when instances are terminated and replaced spinning up an instance (actually, a load-balanced pair, probably spanning AZs) to act as an AWS-API proxy for all API traffic I guess I'm wondering whether there's some kind of back-door we can open that allows our VPC EC2 instances access to the AWS API endpoints, but nothing else, for cheap-complexity setup, that doesn't add another network-hop layer to our infrastructure for serving requests.

  • Amazon EC2 EBS volume scheduled backup/snapshots using puppet

    - by Ehrann Mehdan
    I am not a Linux admin, although I wish I was, and I have seen these questions Amazon EC2 Backup Strategy Amazon EC2 + EBS:: Regular backup plan? Simple Backup Strategy for Amazon EC2 instances / volumes? And this suggestion http://alestic.com/2009/09/ec2-consistent-snapshot I tried using command line + crontab (the command line works, but crontab for some reason, doesn't) But I'm still pretty lost, all I want is an automated, rolling backup of my amazon EC2 (EBS) data (by rolling I mean keep 3-4 weeks back, but delete old snapshots as new ones come for cost control) And as things usually go, if there is something that is hard and painful, someone creates a solution for it. My question is simple, is there a way using a tool like Puppet to do it without a painful learning curve? (or via other tools like http://ylastic.com) If yes, how?

  • How to secure a group of Amazon EC2 instances

    - by ks78
    I have several Amazon EC2 instances running Ubuntu 10.04 and I've recently started using Amazon's Route 53 as my DNS. The purpose of doing that was to allow the instances to refer to each other by name rather than private IP (which can change). I've pointed my domain name (via GoDaddy) to Amazon's name servers, allowing me to access my EC2 webservers. However, I noticed I can now access the EC2 instances which I don't want to be public, such as the dedicated MySQL Server. I was thinking Amazon's Security Groups would still be in effect when using Route 53, but that doesn't seem to be the case. Before I started using Route 53, I was thinking of having one instance run a reverse proxy, which would help protect the web servers behind it. Then IP-restrict all the other instances. I know IP restricting can be done using the firewall within each instance, but should I ever need to access them from another IP address, I'd need a way in. Amazon's control panel made it a breeze to open a port when necessary. Does anyone have any suggestions for keeping EC2 instances secure, but also accessible to their administrator? Also, what's the best topology for a group of EC2 instances, consisting of web servers and a dedicated database server, from a security perspective? Does having a reverse proxy server even make sense?

  • Using Amazon's EBS for MySQL hot backup

    - by flybywire
    What are your experiences using Amazons EBS snapshot features for MySql hot backups. I have a database running a batch processing job in ec2. I backup with EBS snapshot. So far the backups looks consistent. But I am afraid they "will stop being consistent as soon as I stop checking" (Uncertainty principle). What are your experiences with backuping relational databases (and mysql in particular) with ebs snapshot?

  • Amazon Web Services : Fault tolerant solution

    - by Algorist
    Hi, I am using Boto library to write scripts for automating our jobs on AWS. My script actually starts a hadoop cluster using cloudera scripts and then does some customization. I am having a problem with retries. Seems like very command in my script fails once couple of days. I started adding retry to all the commands, but then the code is very clumsy and difficult to maintain. what do people do in general. Thank you Bala

  • (Newbie) Amazon Web Services Apache Server

    - by Samnsparky
    Hello! I am trying to get a feel for the costs imposed by running apache on AWS continually. Assuming that the service is scarcely used, does anyone know how many cpu hours that would eat up in a month just by sitting there and running? I understand that this is slightly impractical but I am trying to figure out what the cost of entry is to deploy an application on this platform (as compared to GAE). I suspect it to be small but I would like to know. Thank you for your help, Sam

  • Amazon EC2 Nat Instance - goes out but not back in

    - by nocode
    I've followed Amazon's steps and list what I've done. I've created 6 subnets (4 private SN1: 10.50.1.0/24, SN2: 10.50.2.0/24, SN3: 10.50.3.0/24, SN4: 10.50.4.0/24) and 2 public (SN5: 10.50.101.0/24 and SN6: 10.50.102.0/24) -I have a Bastion host and a NAT instance on SN5 and assigned EIP's to both. I created a test instance on SN1. edit: -NAT instance has source/destination check disabled -On the NAT instance, I had enabled the following commands to be bootstrapped: echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -s 10.0.0.0/16 -j MASQUERADE -In my VPC, the private subnets have their own route table and configured 0.0.0.0/0 to the NAT instance with 4 subnets being associated with the route table. I have a second route table for my public subnets and 0.0.0.0/16 is pointed towards the IGW (with the other 2 subnets associated with it). -For Security Groups, I have the NAT instance accepting all traffic on each of the 4 subnets and all OUTBOUND traffic is allowed. For my test server, I have allowed all outbound access and have allowed all traffic from the public subnet of the NAT host. I can ping internally with no issues. On my test instance, if I try to ping google.com, DNS resolves however I don't get a reply back. On my NAT instance, I run a tcpdump and can see the request being requested to google.com but it's not sending the reply back. My NAT host can ping and receive a reply from google. From the test host, when I ping the NAT instance, the tcpdump shows a request and receive. Is there something I'm missing? EDIT: I've figured it out - I had to save the iptable config and restart the service.

  • Amazon EC2: possible to use elastic load balancing across web servers in multiple regions based on location of client?

    - by Tony
    Related to an another question I asked. This question seems similar but I'm wondering if there are any updates. To support a single site that has users all over the world, I will create EC2 web servers in the US, Asia and Europe regions. The web server instances in the US and Asia regions will be backed by RDS replicas. Is it possible to load balance across these three regions? So when a customer from Spain goes to example.com, she should be routed to the EC2 instances in Europe region, a customer in Miami should be sent to the instance in Eastern US region, etc. Is this possible to do this with just AWS features? Are there docs on how to set this up?

  • Understanding where an amazon ec2 instance run?

    - by kenzo450D
    I am currently using the aws api from my local desktop. I can successfully take backups of my amazon volumes, and even create an ami from it. Now when i wanted to run the instance to be built from this ami, where does the instance run? In their Elastic Cloud or the computer from which the command was issued. Suppose I want to create the new instance in a new region? (locations as defined in ec2-describe-regions) How would I do that? It seems i have a bad knowledge about how the relation between amazon volumes and instances? Please explain it. I am only allowed to use the CLI tools to do all of my work. I made a new snapshot of the existing instance, made an ami using ec2-register, made a keypair, and then followed these steps, http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/launching-an-instance.html#launching-an-instance-cli but i got an error as this Client.InvalidParameterValue: The requested instance type's architecture (i386) does not match the architecture in the manifest for aki-fc37bacc (x86_64) my local computer is 32bit. But I do not want to load instance on the local computer but on amazon servers?

  • Amazon AWS VPN how to open a port?

    - by Victor Piousbox
    I have a VPN with public and private subnets; I am considering only public subnet for now. The node 10.0.0.23, I can ssh into it. Let's say I want to connect to MySQL on the node using its private address: ubuntu@ip-10-0-0-23:/$ mysql -u root -h 10.0.0.23 ERROR 2003 (HY000): Can't connect to MySQL server on '10.0.0.23' (111) ubuntu@ip-10-0-0-23:/$ mysql -u root -h localhost Welcome to the MySQL monitor. Commands end with ; or \g. --- 8< --- snip --- 8< --- mysql> The port 3306 is not reachable if I use the private IP? My security group allows port 3306 inbound from 0.0.0.0/0 AND from 10.0.0.0/24. Outbound, allowed all. The generic setup done by Amazon through their wizard does not work... I add ACL that allows everything for everybody, still does not work. What am I missing?

  • Amazon EC2, fastest way to get a node into an existing cluster

    - by imaginative
    I'm new to Amazon AWS. A lot of the time I hear about people folks spawning instances and almost instantly putting them behind a load balancer and into an existing cluster. In the traditional world of managed machines, this would include provisioning hardware, installing an OS, configuring the network on the machine and once the network is available, use a tool of your choice such as CFengine, Puppet or Chef to bootstrap the machine based on its class. It seems like there are "shortcuts" that are able to get a server of a particular class up and running in Amazon EC2. If I have a particular stack running on my server, such as erlang, tomcat6 etc.. what's the fastest way to get these up and running and hooked into Amazon's load balancer? From network, to software stack to kernel tuning? Is it a combination of creating an AMI then running a tool like Puppet against the new instance? Any idea

  • Alias multiple DNS entries to one Amazon S3 Bucket

    - by Tristan
    I have a bucket on Amazon S3. Lets call it "webstatic.mydomain.com". I have a DNS alias setup for that bucket webstatic.mydomain.com CNAME - web-static.mydomain.com.s3.amazonaws.com. This all works great, however for some rather complicated reasons I now need: webstatic.myOtherDomain.com to point to that same amazon bucket so: webstatic.myOtherDomain.com CNAME - web-static.mydomain.com.s3.amazonaws.com. Fails, as the bucket is not called the same as the referring DNS. Can anyone tell me how to have two different DNS entries pointing to the same amazon bucket?

  • Challenges w.r.t. proximity between application hosted outside Amazon and Amazon persistence service

    - by Kabeer
    Hello. This is about hosting a web portal. Earlier my topology was entirely based on Amazon AWS but the price factor (especially for EC2) now makes me re-think. I'll now quickly come to what I have finally arrived at. I'll launch the portal that'll be hosted on Godaddy (unlimited plan on Windows). The portal uses SimpleDB for storing metadata and S3 for blobs. Locally available MySQL will be used for the ASP.Net provider services. Once the portal is profitable, I intent to move to Amazon in totality. Now considering the proximity between Godaddy & Amazon, would I face 'substantial' performance problems? Are there any suggestions to improve upon my topology.

  • ssh timeout issue connecting to an EC2 instance on OS X

    - by mamusr
    I am new to AWS and not a networking expert but curious to know more about it. I created a VPC with a public subnet only. Then i created an EC2 instance using an Ubuntu 14.04 64-bit pv AMI image (ami-e84d8480) as well generating the key pair needed to connect to it through ssh. I followed amazon's instructions to connect to an EC2 instance via ssh which did not work. Here is my attempted input and debug log: Running on OS X 10.9.4 user$ ssh -vvv -i key.pem [email protected] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 102: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 22. debug1: connect to address xxx.xxx.xxx.xxx port 22: Operation timed out ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out To attempt to resolve the issue: I enabled the SSH port. Tried different usernames other than ubuntu, like ec2-user and root. Initially set an inbound ssh rule in the security group to connect to only my ip address. When that did not work, i changed it to allow any ip to connect. But those actions did not fix the problem. Here are my guesses as to what i am missing in getting the EC2 instance connection to work. My etc/ssh_config file may be preventing the connection from taking place. I may have missed an important networking detail when setting up the VPC. I do not have a public ip address specified for the instance. I am connecting through the private ip address. My questions for the community: Am i going about it the wrong way connecting to the instance through the private ip address? if so, do i need to specify a public ip address for it to connect or some other method?

  • Amazon EC2 tools for Debian?

    - by Jonik
    What is the recommended way of getting command-line Amazon EC2 tools on Debian? So, basically the same as this question, but for EC2 instead of S3. Ubuntu has ec2-ami-tools and ec2-api-tools, but I couldn't find equivalent packages for Debian. A blog post titled "Install EC2 AMI & API tools in Debian" talks about installing Amazon's packages outside package management, but that seems a little clumsy.
