Enable MySQL Binary Logging: Quick Guide

To enable the MySQL binary logging feature, you need to follow the steps below:

1. Edit the MySQL configuration file my.cnf, locate and open the following configuration option, if it’s not there already, manually add it:

log_bin = /var/log/mysql/mysql-bin.log

The log_bin here specifies the path and filename of the binary log file.

1. Restart the MySQL service to apply the configuration changes.
2. You can connect to the MySQL server using MySQL command line tool or client, and execute the following command to check if binary logging is enabled:

SHOW VARIABLES LIKE 'log_bin';

If the output displays the value of log_bin as ON, it means that binary logging has been successfully enabled.

1. After enabling binary logging in MySQL, all update operations will be recorded in the binary log file, which can be viewed to perform data recovery, replication, and other operations.

It is important to note that enabling binary logging will increase the system’s burden, as MySQL will continuously record update operations to log files. Therefore, before enabling binary logging, it is necessary to evaluate whether the system’s performance and storage space can meet the requirements.
