在Port 22下面加一行，以端口50000为例，Port 50000</p>
<p>
然后保存，重启ssh服务systemctl restart sshd.service</p>

如果是yes就是添加成功，如果是no就是没成功</p>
<p>
成功后重载防火墙firewall-cmd –reload</p>
<p>
<strong>【关闭selinux】</strong></p>
<p>
查看selinux状态sestatus，如果是enabled就是开启状态</p>

<p>
修改SELINUX=disabled</p>
<p>
然后重启vps试试用新的50000端口登录，如果登录成功再vi /etc/ssh/sshd_config把Port 22端口删除，再重启ssh服务就好了。</p>
