mysql 查询日志开启

1. 查看当前是否已经开启了与log保存路径

mysql> show variables like 'general_%';
+------------------+-------------------------------+
| Variable_name    | Value                         |
+------------------+-------------------------------+
| general_log      | OFF                           |
| general_log_file | /usr/local/mysql/data/YSM.log |
+------------------+-------------------------------+

2. 修改OFF为ON

mysql> set global general_log=ON;
Query OK, 0 rows affected (0.03 sec)


mysql> show variables like 'general_%';
+------------------+-------------------------------+
| Variable_name    | Value                         |
+------------------+-------------------------------+
| general_log      | ON                            |
| general_log_file | /usr/local/mysql/data/YSM.log |
+------------------+-------------------------------+
