小編給大家分享一下Linux下怎么查看mysql數(shù)據(jù)庫操作記錄，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
MySQL中的參數(shù)general_log用來控制開啟、關閉MySQL查詢?nèi)罩?參數(shù)general_log_file用來控制查詢?nèi)罩镜奈恢?。所以如果你要判斷MySQL數(shù)據(jù)庫是否開啟了查詢?nèi)罩荆梢允褂孟旅婷?。general_log為ON表示開啟查詢?nèi)罩?，OFF表示關閉查詢?nèi)罩尽?/p>
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的查詢?nèi)罩局С謱懭胛募驅(qū)懭霐?shù)據(jù)表兩種形式，這個由參數(shù)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)
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)
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)
如果設置log_output=table的話，則日志結果會記錄到名為gengera_log的表中，這表的默認引擎是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)
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)
