我编写了这个脚本，它现在在未安装 SElinux 的系统上完美运行。
echo Enter server IP:
read server
scp /home/Zenoss/.ssh/authorized_keys random@$server:/home/random
sshpass -p randompassword ssh -t random@$server sudo -i 'useradd zenoss; sudo mkdir /home/zenoss/.ssh; sudo mv /home/random/authorized_keys /home/zenoss/.ssh/;
sudo chmod 700 /home/zenoss/.ssh;
sudo chmod 600 /home/zenoss/.ssh/authorized_keys;
sudo chown -R zenoss /home/zenoss/.ssh;
sudo chgrp -R zenoss /home/zenoss/.ssh;
exit'
因此，在没有 SELinux 的服务器上，脚本可以运行，然后 Zenoss 可以通过 SSH 登录到远程服务器并开始监控。但是在启用了 SELinux 的系统上，脚本可以运行，但 Zenoss 无法通过 SSH 连接到远程服务器，调试信息显示它没有看到已成功设置的 authorized_keys 文件。

有谁知道是什么原因造成的，以及我该如何解决它，禁用 SELinux 不是一个选择。

答案1
很可能是文件的上下文.ssh有.ssh/authorized_keys误。请执行sudo restorecon -R -v /home/zenoss/.ssh并重试。
