mysql打开general log的办法

 

mysql打开general log之后,所有的查询语句都可以在general log

文件中以可读的方式得到,但是这样general log文件会非常大,所以默认

都是关闭的。有的时候为了查错等原因,还是需要暂时打开general log的。 

   

 

mysql@localhost.(none)>show global variables like "%genera%";

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

| Variable_name | Value |

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

| general_log | OFF |

| general_log_file | /data1/mysql9999/etch171.log |

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

2 rows in set (0.00 sec)

 

mysql@localhost.(none)>set global general_log=on;

Query OK, 0 rows affected (0.02 sec)

 

mysql@localhost.(none)>set global general_log=off;

Query OK, 0 rows affected (0.00 sec)
