本文简单介绍了影响mysqld安全的四个选项。

--secure

 

由gethostbyname()系统调用返回的IP数字被检查,确保他们解析回到原来的主机名。这对某些外人通过模仿其它主机获得存取权限变得更难。这个选项也增加一些聪明的主机名检查。

 

--skip-grant-tables

 

这个选项导致服务器根本不使用权限系统。这给每个人以完全存取所有的数据库的权力!(通过执行mysqladmin reload,你能告诉一个正在运行的服务器再次开始使用授权表。)

 

--skip-name-resolve

 

主机名不被解析。所有在授权表的Host的列值必须是IP数字或localhost。

 

--skip-networking

 

在网络上不允许TCP/IP连接。所有到mysqld的连接必须经由Unix套接字进行。这个选项对使用MIT-pthreads的系统是不合适的,因为MIT-pthreads包不支持Unix套接字。
