在优化MYSQL配置时,加入 skip-name-resolve ,在重新启动MYSQL时检查启动日志,发现有警告信息

120726 11:57:22 [Warning] 'user' entry 'root@localhost.localdomain' ignored in --skip-name-resolve mode. www.2cto.com

120726 11:57:22 [Warning] 'user' entry '@localhost.localdomain' ignored in --skip-name-resolve mode.

skip-name-resolve是禁用dns解析,避免网络DNS解析服务引发访问MYSQL的错误,一般应当启用。

启用后,在mysql的授权表中就不能使用主机名了,只能使用IP ,出现此警告是由于mysql 表中已经存在有 localhost.localdomain 帐号信息。 www.2cto.com

我们把它删除就好了。
代码如下:
mysql>use mysql;
mysql> delete from user where HOST='localhost.localdomain';
Query OK, 2 rows affected (0.00 sec)

重启MYSQL ,发现警告已经没有啦。
