一步步查竟然发现时mysql log 文件占用了这几个G的空间.

[root@phpfans var]# mysql -u root -p

26 rows in set (0.00 sec)

可以看到从17-24这几个文件每个到到达1G左右.足足占了8G空间.非清理不可了

mysql> purge binary logs to 'mysql-bin.000025';
Query OK, 0 rows affected (11.69 sec)

删除 25 以回的log文件.

mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |

| mysql-bin.000025 | 692916366 |
| mysql-bin.000026 | 685 |
+------------------+-----------+
2 rows in set (0.00 sec)

mysql>

履行后可以看到25以回的log文件已经被排除
