MariaDB [xxx]> 

  

先查看一下二进制的记录日志是否打开。

MariaDB [xxx]> show variables where Variable_name="general_log";
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| general_log   | ON    |
+---------------+-------+
1 row in set (0.01 sec)

  

我这里看起来是打开的,如果是OFF。则需要打开这个选项:

set global general_log=on;

  

然后确认一下默认的log产生在哪里:

MariaDB [xxx]> show variables where Variable_name="general_log_file";
+------------------+-----------------+
| Variable_name    | Value           |
+------------------+-----------------+
| general_log_file | 10-0-236-38.log|
+------------------+-----------------+
1 row in set (0.00 sec)

  

然后搜索一下它,得到日志路径:

[root@10-0-236-38 ~]# find / -name "10-0-236-38.log"
/var/lib/mysql/10-0-236-38.log

  

大功告成。

[root@10-0-236-38 ~]# vim /var/lib/mysql/10-0-236-38.log
