求助Pam_mysql+vsftp认证的问题

liooge

小弟最近整一个vsftp，想用网上说的那个pam_mysql+vsftp的方法，做了很长时间，仍无法成功！！
总结一下有以下几点：
1、权限问题，我检查了/var/lib/mysql目录的权限owener都是mysql啊！！
2、mysql.sock 文件问题，在错误信息中说是无法使用，但经查路径正确啊！！
3、密码类型，在pam_mysql的配置文件 里我分别试了各种类型的仍不能成功啊，而且在mysql中对应的user表里有一个用户名添加不加密、mysqly方式加密、MD5加密

我的是Federa 11用yum update 一次，但因为剩余空间不足失败了，
值 得一提的是，mysql.sock文件是0字节，但大侠都说OK！！
在我的例子中，各种服务都能启用！！匿名用户也可登录！！唉！！！大家帮下吧！！
