如何显示在 MySQL 上执行的最后一个查询?

How to show the last queries executed on MySQL?(如何显示在 MySQL 上执行的最后一个查询?)

问题描述

Is there any query/way to show the last queries executed on ALL servers?

For those blessed with MySQL >= 5.1.12, you can control this option globally at runtime:

1. Execute SET GLOBAL log_output = 'TABLE';
2. Execute SET GLOBAL general_log = 'ON';
3. Take a look at the table mysql.general_log

If you prefer to output to a file instead of a table:

1. SET GLOBAL log_output = "FILE"; the default.
2. SET GLOBAL general_log_file = "/path/to/your/logfile.log";
3. SET GLOBAL general_log = 'ON';

I prefer this method to editing .cnf files because:

1. you're not editing the my.cnf file and potentially permanently turning on logging
2. you're not fishing around the filesystem looking for the query log - or even worse, distracted by the need for the perfect destination. /var/log /var/data/log /opt /home/mysql_savior/var
3. You don't have to restart the server and interrupt any current connections to it.
4. restarting the server leaves you where you started (log is by default still off)

For more information, see MySQL 5.1 Reference Manual - Server System Variables - general_log
