mysql general log開啓

#先查看當前狀態
mysql> show variables like 'general%';
+------------------+--------------------------------+
| Variable_name    | Value                          |
+------------------+--------------------------------+
| general_log      | OFF                            |
| general_log_file | /data/mysql/data/localhost.log |
+------------------+--------------------------------+
2 rows in set (0.00 sec)

#能夠在my.cnf裏添加,1開啓（0關閉）,固然了,這樣要重啓才能生效,有點多餘了
general-log = 1
log = /log/mysql_query.log路徑

#也能夠設置變量那樣更改,1開啓（0關閉）,即時生效,不用重啓,首選固然是這樣的了
set global general_log=1
#這個日誌對於操做頻繁的庫,產生的數據量會很快增加,出於對硬盤的保護,能夠設置其餘存放路徑
set global general_log_file=/tmp/general_log.log
