今天在centos 6 64位测试安装vsftpd时 发现能正常启动，但用本地用户登录时，发现出现vsftpd 530 login incorrect，出现这种错误会有很多原因。于是开始查看日志/var/log/vsftpd.log，也没发现有价值的信息。再查看/var /log/secure，发现问题了。部分错误代码如下：

    Dec  1 08:07:30 localhost vsftpd: PAM adding faulty module: /lib/security/pam_listfile.so
    Dec  1 08:07:30 localhost vsftpd: PAM unable to dlopen(/lib/security/pam_unix.so): /lib/security/pam_unix.so: cannot open shared objec
    t file: No such file or directory

    Dec  1 08:10:12 localhost vsftpd: PAM adding faulty module: /lib/security/pam_unix.so

错误的意思是相关的安全验证文件找不到，通过find查找发现都在/lib64目录下，于是打开文件/etc/pam.d/vsftpd把/lib全部替换成/lib64，重启vsftpd，再登录就正常了。
