Securely Connect to a Remote MySQL Server over SSH in PHP
To establish a secure tunnel for PHP database connectivity, the following SSH tunnel solution offers a robust approach.
SSH Tunnel Setup
- Create an SSH tunnel to your MySQL database server. For this, use a command like:
ssh -fNg -L 3307:10.3.1.55:3306 [email protected]
- Choose a local port (e.g., 3307) and forward all traffic to the remote database server's IP and port (10.3.1.55:3306).
PHP Connection
Once the SSH tunnel is established, you can connect to the database securely through PHP using:
<code class="php">$smysql = mysql_connect( "127.0.0.1:3307", "dbuser", "passphrase" ); mysql_select_db( "db", $smysql ); </code>
This will establish a connection to the remote database via the encrypted SSH tunnel.
Benefits
- Encrypted Communication: Data is transmitted over an encrypted SSH connection, ensuring confidentiality.
- Security Enhancement: Limiting direct access to the database server reduces security vulnerabilities.
- Compatibility: Can be used with various PHP database functions, such as mysql_connect and mysqli_connect.
