Setup keyless login

1. On local make an RSA key if you haven't already (ssh-keygen)
2. Copy that key into .ssh/authorized_keys on the first (i.e. bastion) server (ssh-copy-id [email protected]) 2b. Test that you can ssh [email protected] and connect without password
3. ssh to first.server and create an RSA key on first.server if you haven't already (ssh-keygen)
4. ssh-copy-id to the server you want to access (what I am calling second.server) 4b. test that you can ssh from first.server to second.server without entering a password

To copy from server to local

rsync -e "ssh [email protected] ssh" [email protected]:/path/to/file /path/to/local/dest

Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

• How long is your average request?
• What is the maximum number of simultaneous visitors the site(s) get?
• How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

• sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log
