我编写了这个脚本,它现在可以在没有安装 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'
所以在没有 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 SELinux 的系统上,脚本可以工作,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。

有谁知道这是什么原因以及我如何解决它,禁用 SELinux 不是一个选项。
韩国
.ssh
和文件的上下文很可能.ssh/authorized_keys
是错误的。做一个sudo restorecon -R -v /home/zenoss/.ssh
然后再试一次。
