ec2ssh is a shell script that makes connecting to ec2 servers ridiculously easy.
ec2ssh displays your instances in a simple digest-like menu and prompts you to enter the server number. Once you enter it, the script opens an ssh connection to the server.
Parameters are optional, but very handy if you run many sites. The parameter acts as a filter to narrow down the list of servers.
$ ec2ssh No. Instance Sec. group Domain name Tag 1 i-af23fa32 sg-223af233 ec2-107-20-76-111.compute-1.amazonaws.com LIVE Web A 2 i-232abc23 sg-223af233 ec2-107-22-12-222.compute-1.amazonaws.com LIVE Web B 3 i-892a98b3 sg-ccca2223 ec2-107-22-12-223.compute-1.amazonaws.com DEV MySQL A 4 i-123ab23c sg-ccca2223 ec2-107-22-12-224.compute-1.amazonaws.com DEV MySQL B 5 i-98ca2532 sg-ccca2223 ec2-107-22-12-225.compute-1.amazonaws.com DEV MySQL C Enter server number, server range (e.g. 3..5) or list of servers (e.g. 2 3 4 8 9): 1 Ssh-ing to ec2-107-20-76-111.compute-1.amazonaws.com
If you include a parameter the list would be narrowed down to servers whose instance, security group, domain name or tag matches the parameter. This is extremely useful if you run lots of instances. Example parameters:
ec2ssh live- lists all servers whose tag contains 'LIVE'
ec2ssh mysql- lists all servers whose tag contains 'MySQL'
ec2ssh sg-223af233- lists all servers in the specified security group
ec2ssh i-98ca2532- lists a specific server matched by its instance id.
Note: Matches are case insensitive.
When prompted for the server(s) you can enter one or more numbers in the following format:
3- Ssh to third server in the menu
1 4- Ssh to first and forth server
1..4- Ssh to all servers in the range from 1 to 4, i.e. 1, 2, 3 and 4.
When you specify multiple servers, it connects you to the first one. When you exit, it ssh's you to the next, etc.
ec2ssh is a bash script that requires Amazon EC2 API tools and awk (comes with most Mac, Unix and Linux systems by default).
- Manual deployments
- Server (instance) maintenance
- One-off tasks that take less time than writing deployment scripts
- You ♥ ssh.
