1、修改my.cnf

#整体的效果，全局开启表和日志文件都写，但是对于general_log只写表，对于slow_query_log，表和日志文件都记录。

general_log=1#开启mysql执行sql的日志 slow_query_log=1#开启mysql慢sql的日志

#设置之后会影响general_log和slow_query_log，

log_output=table,File#日志输出会写表，也会写日志文件，为了便于程序去统计，所以最好写表

#这里没配置general_log_file，那么general_log就只会写表了

#在mysql5.1.29以上，设置以下即可打开mysql将执行的sql记录在文件中

#general_log_file=/log/general.log

#5.1.29以以前为：

#log=/var/lib/mysql/sql_row.log

long_query_time=1#设置mysql的慢查询为超过1s的查询 slow_query_log_file=/log/slow.log

2、修改mysql的日志表(在mysql库中)的格式

#默认general_log是csv的格式，修改为MyISAM格式查询效率会高很多

set global general_log = off;

alter table general_log engine = MyISAM;

set global general_log = on;

#默认slow_query_log是csv的格式，修改为MyISAM格式查询效率会高很多

set global slow_query_log = off;等于0效果一样

alter table slow_log engine = MyISAM;

set global slow_query_log = on;等于1效果一样

3、因为mysql的日志表：general_log和slow_query_log不允许修改，所以需要新建出一个便于删除修改的表(这个日志表太大，需要定期清理n天前得数据)

建立slow_log_dba的表

CREATE TABLE `slow_log_dba` (

`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

) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='Slow log for dba';

建立general_log_dba的表

CREATE TABLE `general_log_dba` (

`event_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

`user_host` mediumtext NOT NULL,

`thread_id` int(11) NOT NULL,

`server_id` int(10) unsigned NOT NULL,

`command_type` varchar(64) NOT NULL,

`argument` mediumtext NOT NULL,

KEY `user_host` (`user_host`(200)),

KEY `event_time` (`event_time`)

) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='general log for dba op';

4、因为程序最终使用的general_log_dba和slow_log_dba的表，所以需要定时的将general_log和slow_query_log的数据拷贝到general_log_dba和slow_log_dba之中

因为报告是每天生成一次，所以这个动作只要每天操作一次即可

#脚本是保存10天得数据，每天将general_log和slow_query_log的数据拷贝到general_log_dba和slow_log_dba之中

#做定时任务每天执行一次 mysqllogtable.sh

#!/bin/sh

NDaysAgo=$(date -d '-10 days' "+%F %H:%M:%S")

/usr/local/mysql/bin/mysql -uXXXX -p'xxxxxxxx' -D'mysql' -e "insert general_log_dba select * from general_log;

truncate general_log;

delete from general_log_dba where event_time < \"$NDaysAgo\";

insert slow_log_dba select * from slow_log;

truncate slow_log;

delete from slow_log_dba where start_time < \"$NDaysAgo\""

5、python脚本写统计每天sql操作和每天的mysql的慢查询(脚本中有部分是可以抽象的方法，请自己酌情处理)

统计mysql每日执行记录的脚本
