步骤一： 在/etc/pam.d/login 文件中末尾添加一行
[weblogic@kjgl-web ~]$ 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 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
session required pam_limits.so #要有这一行
步骤二：在/etc/pam.d/sshd 文件中末尾添加一行
[weblogic@kjgl-web ~]$ cat /etc/pam.d/sshd #这个文件就新建一个，添加如下内容
#%PAM-1.0
auth required pam_sepermit.so
auth include password-auth
account required pam_nologin.so
account include password-auth
password include password-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session required pam_loginuid.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open env_params
session required pam_namespace.so
session optional pam_keyinit.so force revoke
session include password-auth
session required pam_limits.so #要有这一行
步骤三：修改sshd的配置文件，开启PAM功能
[weblogic@kjgl-web ~]$ grep -n Use /etc/ssh/sshd_config
46:#AuthorizedKeysCommandUser nobody
52:#IgnoreUserKnownHosts no
82:UsePAM yes #开启
83:UseLogin yes #开启
91:#X11UseLocalhost yes
96:#PermitUserEnvironment no
100:#UseDNS no
114:#Match User anoncvs
步骤四：重启sshd 即可
/etc/init.d/sshd restart
