X64 Linux无法从本地字符界面登陆解决 经常有怪事发生。话说,我有一台负责squid的服务器,远程登陆好好的就一直由她好好地。 今天要改个网关,于是就接了个显示器在本地操作。 当输入完用户名 root 密码 * 回车 哟,又让我再输一次?? 好了,我再输了,还是这样!死活就账号认证的界面登陆不上。 丫的,服务器被黑了?? 用笔记本登陆却一切正常。 查看服务器安全日志: tail -50 /var/log/secure 发现有以下错误: May 2 18:45:41 server1 login: PAM unable to dlopen(/lib/security/pam_limits.so) May 2 18:45:41 server1 login: PAM [error: /lib/security/pam_limits.so: wrong ELF class: ELFCLASS32] May 2 18:45:41 server1 login: PAM adding faulty module: /lib/security/pam_limits.so May 2 18:45:45 server1 login: pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=tty1 ruser= rhost= user=root May 2 18:45:46 server1 login: FAILED LOGIN 1 FROM (null) FOR root, Authentication failure May 2 18:46:05 server1 login: FAILED LOGIN 2 FROM (null) FOR root, Authentication failure May 2 18:46:15 server1 login: pam_unix(login:session): session opened for user root by LOGIN(uid=0) May 2 18:46:15 server1 login: Module is unknown 由于操作系统是 RedHat As5.3 X64 之前的经验暗示我,这很有可能跟 X64 类文件的存放路径有关。 于是编辑登陆配置文件: vim /etc/pam.d/login 把最下一行 session required /lib/security/pam_limits.so 修改为: session required /lib64/security/pam_limits.so 保存并退出。 再试试在本地登陆,成功!日志没再报错了。
修改后的/etc/pam.d/login文件
