小编给大家分享一下Linux下怎么查看mysql数据库操作记录，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
Linux下查看mysql数据库操作记录具体方法
MySQL中的参数general_log用来控制开启、关闭MySQL查询日志,参数general_log_file用来控制查询日志的位置。所以如果你要判断MySQL数据库是否开启了查询日志，可以使用下面命令。general_log为ON表示开启查询日志，OFF表示关闭查询日志。
mysql> show variables like '%general_log%';+------------------+------------------------------+| Variable_name | Value |+------------------+------------------------------+| general_log | OFF || general_log_file | /var/lib/mysql/DB-Server.log |+------------------+------------------------------+2 rows in set (0.00 sec)另外，MySQL的查询日志支持写入文件或写入数据表两种形式，这个由参数log_output控制，如下所示：
mysql> show variables like 'log_output';+---------------+-------+| Variable_name | Value |+---------------+-------+| log_output | FILE |+---------------+-------+1 row in set (0.00 sec)开启MySQL查询日志
mysql> set global general_log = on;Query OK, 0 rows affected (0.11 sec)mysql> show variables like 'general_log';+---------------+-------+| Variable_name | Value |+---------------+-------+| general_log | ON |+---------------+-------+1 row in set (0.02 sec)关闭MySQL查询日志
mysql> show variables like 'general_log';+---------------+-------+| Variable_name | Value |+---------------+-------+| general_log | ON |+---------------+-------+1 row in set (0.01 sec)mysql> set global general_log=off;Query OK, 0 rows affected (0.01 sec)mysql> show variables like 'general_log';+---------------+-------+| Variable_name | Value |+---------------+-------+| general_log | OFF |+---------------+-------+1 row in set (0.00 sec)设置日志输出方式为表
如果设置log_output=table的话，则日志结果会记录到名为gengera_log的表中，这表的默认引擎是CSV）。
mysql> show variables like 'log_output';+---------------+-------+| Variable_name | Value |+---------------+-------+| log_output | FILE |+---------------+-------+1 row in set (0.00 sec)mysql> set global log_output='table';Query OK, 0 rows affected (0.00 sec)mysql> show variables like 'log_output';+---------------+-------+| Variable_name | Value |+---------------+-------+| log_output | TABLE |+---------------+-------+1 row in set (0.01 sec)查看查询日志信息。
mysql> select * from mysql.general_log;+---------------------+---------------------------+-----------+-----------+--------------+----------------------------------+| event_time | user_host | thread_id | server_id | command_type | argument |+---------------------+---------------------------+-----------+-----------+--------------+----------------------------------+| 2017-07-06 12:32:05 | root[root] @ localhost [] | 1 | 1 | Query | show variables like 'general%' || 2017-07-06 12:32:28 | root[root] @ localhost [] | 1 | 1 | Query | show variables like 'log_output' || 2017-07-06 12:32:41 | root[root] @ localhost [] | 1 | 1 | Query | select * from MyDB.test || 2017-07-06 12:34:36 | [root] @ localhost [] | 3 | 1 | Connect | root@localhost on || 2017-07-06 12:34:36 | root[root] @ localhost [] | 3 | 1 | Query | KILL QUERY 1 || 2017-07-06 12:34:36 | root[root] @ localhost [] | 3 | 1 | Quit | || 2017-07-06 12:34:51 | root[root] @ localhost [] | 1 | 1 | Query | select * from mysql.general_log |+---------------------+---------------------------+-----------+-----------+--------------+----------------------------------+7 rows in set (0.02 sec)以上是“Linux下怎么查看mysql数据库操作记录”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注编程网行业资讯频道！
