If you want to output to the log file: SET GLOBAL log_output = “FILE”; SET GLOBAL general_log_file = “/path/to/your/logfile.log” SET GLOBAL general_log = ‘ON’; Restart MySQL to apply the changes if you edit the config, e.g. /etc/mysql/my.cnf Now, if you’d like you can tail -f /var/log/mysql/mysql.log。
