mysql跟踪日志

第一步 创建以下两个 日志表

  CREATE TABLE `slow_log` (
   `start_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP 
                          ON UPDATE CURRENT_TIMESTAMP,
   `user_host` mediumtext NOT NULL,
   `query_time` time NOT NULL,
   `lock_time` time NOT NULL,
   `rows_sent` int(11) NOT NULL,
   `rows_examined` int(11) NOT NULL,
   `db` varchar(512) NOT NULL,
   `last_insert_id` int(11) NOT NULL,
   `insert_id` int(11) NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `sql_text` mediumtext NOT NULL,
   `thread_id` bigint(21) unsigned NOT NULL
  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='Slow log'

  CREATE TABLE `general_log` (
   `event_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
                          ON UPDATE CURRENT_TIMESTAMP,
   `user_host` mediumtext NOT NULL,
   `thread_id` bigint(21) unsigned NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `command_type` varchar(64) NOT NULL,
   `argument` mediumtext NOT NULL
  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='General log'

第二步 在数据库上开启 查询日志

SET global general_log = 1;
SET global log_output = 'table';

第三步 查询日志

select * from mysql.general_log

第四步 在数据库上关闭 查询日志

SET global general_log = 0;

 

第五步 清除数据库 日志

truncate table mysql.general_log;
