通过基于密钥的身份验证通过PHP连接到EC2实例上的MySql

Question

I have an EC2 instance running a mysql server, and the server uses key-based authentication to connect to it. I am needing to connect to the mysql server on this EC2 instance through PHP from a different non-amazon server. Is this possible? If so, how do I do this? Do I need to use ssh2 connection functions in PHP? Obviously, I can't just use mysql_connect because the server uses key-based authentication. Any help anyone could give would be greatly appreciated.

Answer 1

I am going to assume that by key based authentication you mean ssh keys and not connecting to mysql with keys.

So you have a couple of options.

1. Use an SSH tunnel. This uses an ssh listener on your non-amzn server and forwards all communications to mysql instance via SSH. This is more secure, but not without some overhead.

2. If security is less of a concern you can open your security groups to the ip of the non-amzn server and set up a connection directly to port 3306 (or whatever port you are using)

In any case, you will end up with some latency running queries like this. Depending on the connection between your servers.
