重启sshd服务,导致ssh连接不上服务器,经过排查,查看日志发现出现一下错误

Oct 25 12:59:00 kdgcapp-58-106 sshd[7413]: PAM unable to dlopen(/usr/lib64/security/pam_stack.so): /usr/lib64/security/pam_stack.so: cannot open shared obje... directory
Oct 25 12:59:00 kdgcapp-58-106 sshd[7413]: PAM adding faulty module: /usr/lib64/security/pam_stack.so

解决方法:

经过排查发现是ssh rpm 升级后会修改/etc/pam.d/sshd 文件,如下:

#%PAM-1.0
auth       required     pam_stack.so service=system-auth
account    required     pam_nologin.so
account    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth

修改为之前的即可。修改后的文件如下:

#%PAM-1.0
auth       required     pam_sepermit.so
auth       include      password-auth
account    required     pam_nologin.so
account    include      password-auth
password   include      password-aut
# 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    optional     pam_keyinit.so force revoke
session    include      password-auth
