What is the recommended way to connect to MySQL remotely on DigitalOcean?

The recommended way to connect to MySQL remotely on DigitalOcean is to use SSH tunneling for secure and encrypted communication between your local machine and the MySQL server. This involves setting up an SSH tunnel to forward the MySQL port from the remote server to your local machine.

Here are the steps to connect to MySQL remotely on DigitalOcean using SSH tunneling:

1. Enable remote access to MySQL on the DigitalOcean server by editing the MySQL configuration file to allow connections from remote hosts. You can do this by locating the 'bind-address' line in the MySQL configuration file (usually located at /etc/mysql/my.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf) and changing it to the IP address of your server or to 0.0.0.0 to allow connections from any remote host.
2. Restart the MySQL server to apply the changes by running the following command:

1

sudo systemctl restart mysql

1. Install and configure an SSH client on your local machine if you haven't already.
2. Establish an SSH connection to your DigitalOcean server using the following command, replacing 'your_username' and 'server_ip' with your actual username and server IP address:

1

ssh -L 3306:127.0.0.1:3306 your_username@server_ip

1. The above command creates an SSH tunnel that forwards the remote MySQL port 3306 to your local machine's port 3306. Keep this SSH connection open in one terminal window.
2. In a new terminal window on your local machine, connect to the MySQL server using the following command, replacing 'db_username' and 'db_password' with your MySQL database username and password:

1

mysql -u db_username -p -h 127.0.0.1

1. You should now be connected to the MySQL server remotely through the SSH tunnel. You can run SQL queries and manage your databases as needed.

Remember to close the SSH tunnel and connection when you are done using the MySQL server. The SSH tunneling method ensures secure and encrypted communication between your local machine and the remote MySQL server on DigitalOcean.
