A. 進入防火牆配置文件:/etc/firewalld/zones/public.xml裡,刪除<servicename="ssh"/>
使用命令firewall-cmd --add-port=22/tcp增加端口，並通過命令firewall-cmd--list-all查看端口是否增加成功. netstat -ano|grep 22測試是否通過.
B.使用systemctl status sshd.service查看ssh服務, 使用命令systemctl stop sshd.service結束ssh服務.
C.使用systemctl statussshd. service查看服務狀態，再使用命令systemctl disable sshd.service開機禁用ssh服務，
