RHEL 6.1字符界面无法登录SSH却能登录

1.具体版本：

2.具体现象：

每次输入用户名密码登录之后又跳到这个界面。但是用ssh却可以登录。

3.查看日志

[root@localhost ~]# tail -f /var/log/secure
Feb   :: localhost login: PAM adding faulty module: /lib/security/pam_limits.so
Feb   :: localhost login: pam_unix(login:session): session opened for user oracle by LOGIN(uid=)
Feb   :: localhost login: Module is unknown
Feb   :: localhost login: pam_unix(login:session): session opened for user root by LOGIN(uid=)
Feb   :: localhost login: ROOT LOGIN ON tty1
Feb   :: localhost login: pam_unix(login:session): session closed for user root
Feb   :: localhost login: PAM unable to dlopen(/lib/security/pam_limits.so): /lib/security/pam_limits.so: cannot open shared object file: No such file or directory
Feb   :: localhost login: PAM adding faulty module: /lib/security/pam_limits.so
Feb   :: localhost login: pam_unix(login:session): session opened for user root by LOGIN(uid=)
Feb   :: localhost login: Module is unknown

找不到目录/lib/security/pam_limits.so

百度了一下在64位机器下应该是/lib64/security/pam_limits.so,于是修改/etc/pam.d/login

4.修改/etc/pam.d/login,修改之后

[root@localhost ~]# cat /etc/pam.d/login
#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
# pam_selinux.so close should be the first session rule
session    required     pam_selinux.so close
session    required     pam_loginuid.so
session    optional     pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
#session    required     /lib/security/pam_limits.so
session    required     /lib64/security/pam_limits.so
session    required     pam_selinux.so open
session    required     pam_namespace.so
session    optional     pam_keyinit.so force revoke
session    include      system-auth
-session   optional     pam_ck_connector.so

5.修改之后重新登录
