Mysql查看sql是否走事务 - 数据库编程

登陆进入服务器

[root@gzmtest_25 ~]# su - mysql

[mysql@gzmtest_25 ~]$ mysql.local

可以看到监控日志是否开启的选项（off是关闭）on是开启

root@localhost:(none)>show global variables like 'general_log%';

+------------------+---------------------------+

| Variable_name    | Value                     |

+------------------+---------------------------+

| general_log      | OFF                       |

| general_log_file |/data/mysql/log/mysql.log |

+------------------+---------------------------+

2 rows in set (0.01 sec)
 
root@localhost:(none)> 

root@localhost:(none)>set global general_log=on;

Query OK, 0 rows affected (0.02 sec)

查看当前系统日志大小

root@localhost:(none)>system du -h /data/mysql/log/mysql.log

1.7M   /data/mysql/log/mysql.log

开启日志成功

接下来就可以直接进入shell中根据sql特征来查看我们sql会话信息

[root@gzmtest_25 ~]# grep "forupdate" /data/mysql/log/mysql.log 126002192 Query select pk fromT_GANTT_CHART where pk =47 for update

//忽略其他的数据了。

执行看当前会话的信息

 [root@gzmtest_25~]# grep 126002192 /data/mysql/log/mysql.log

                   126002192Connect         test@11.104.32.115 on test
