A.  进入防火墙配置文件:/etc/firewalld/zones/public.xml里,删除<servicename="ssh"/>

使用命令firewall-cmd --add-port=22/tcp增加端口，并通过命令firewall-cmd--list-all查看端口是否增加成功. netstat -ano|grep 22测试是否通过.

B.使用systemctl status sshd.service查看ssh服务, 使用命令systemctl stop sshd.service结束ssh服务.

C.使用systemctl statussshd. service查看服务状态，再使用命令systemctl disable sshd.service开机禁用ssh服务，
