无法连接到 Centos 7 服务器（PAM）

尝试安装 PAM 模块（我的第一个模块）后，我遇到了这个问题。我最终将其删除，因为模块损坏，导致用户无法访问系统。现在的情况是，即使删除它，我也无法访问它。

我该如何解决 PAM 的这个故障？

答案1

每个未找到的文件名#015末尾都有一个。这不正常。由于八进制数015是回车符 (CR) 的 ASCII 码，所以在我看来，你可能/etc/pam.d以某种方式编辑了里面的某个文件，使其进入 DOS/Windows 模式（行末为 CRLF，而不是 Linux/Unix 的 LF 行末）。

\015您需要启动救援模式并从备份中恢复损坏的文件。您也可以使用命令删除角色tr。
