Auto Deploy AWS

new_gist_file_0.md

This guide setup Apache2/Passenger/Ruby/Rails/Nginx on CentOS 6.6 64bit

Pre-deployment

# Use ec2-user mode
rvm gemset create <gemset>
rvm gemset use <gemset>

Next, we need to setup the SSH for Capistrano to access the Git:
```ruby
test -e ~/.ssh/id_dsa.pub || ssh-keygen -t dsa # Enter 3 times
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

# Need to do this for CentOS
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys 
restorecon -Rv ~/.ssh

# Accepting host authenticity for user
# Test it (you need to accept the host authenticity):
ssh localhost
# if you did not see any prompt for password, it is done!

# Test: accept host authenticity for git
git ls-remote ssh://ec2-user@[domain]/~/git/[app].git master

Access SSH via authorized_keys

# Your localhost iTerm:
vi ~/.ssh/id_rsa.pub # Copy local ssh key (Command + C)
# ec2-user mode:
vi ~/.ssh/authorized_keys # Paste local ssh key to AWS (Command + V)
