下列mysql的选项影响安全:

--allow-suspicious-udfs

该选项控制是否可以载入主函数只有xxx符的用户定义函数。默认情况下,该选项被关闭,并且只能载入至少有辅助符的UDF。这样可以防止从未包含合法 UDF的共享对象文件载入函数。

--local-infile[={0|1}]

如果用--local-infile=0启动服务器,则客户端不能使用LOCAL in LOAD DATA语句。

--old-passwords

强制服务器为新密码生成短(pre-4.1)密码哈希。当服务器必须支持旧版本客户端程序时,为了保证兼容性这很有用。

(OBSOLETE) --safe-show-database

在以前版本的MySQL中,该选项使SHOW DATABASES语句只显示用户具有部分权限的数据库名。在MySQL 5.1中,该选项不再作为现在的 默认行为使用,有一个SHOW DATABASES权限可以用来控制每个账户对数据库名的访问。

--safe-user-create

如果启用,用户不能用GRANT语句创建新用户,除非用户有mysql.user表的INSERT权限。如果你想让用户具有授权权限来创建新用户,你应给用户授予下面的权限:

mysql> GRANT INSERT(user) ON mysql.user TO 'user_name'@'host_name';

这样确保用户不能直接更改权限列,必须使用GRANT语句给其它用户授予该权限。

--secure-auth
