systemctl reloadt firewalld.service ????????????#重載配置?
systemctl restart firewalld.service ????????????#重啟服務?
systemctl status firewalld.service ?????????????#顯示服務的狀態(tài)?
systemctl enable firewalld.service ?????????????#在開機時啟用服務?
systemctl disable firewalld.service ????????????#在開機時禁用服務?
systemctl is-enabled firewalld.service ?????????#查看服務是否開機啟動?

systemctl --failed ????????????????????????????????????#查看啟動失敗的服務列表?
3、firewall-cmd使用?
firewall-cmd --state ????????????????????????#查看防火墻狀態(tài) ??
firewall-cmd --reload ???????????????????????#更新防火墻規(guī)則 ??
firewall-cmd --state ????????????????????????#查看防火墻狀態(tài) ??
firewall-cmd --reload ???????????????????????#重載防火墻規(guī)則 ??
firewall-cmd --list-ports ???????????????????#查看所有打開的端口 ??
firewall-cmd --list-services ????????????????#查看所有允許的服務 ??
firewall-cmd --get-services ?????????????????#獲取所有支持的服務 ??
#區(qū)域相關(guān)?
firewall-cmd --list-all-zones ???????????????????#查看所有區(qū)域信息 ??
firewall-cmd --get-active-zones ?????????????????#查看活動區(qū)域信息 ??
firewall-cmd --set-default-zone=public ??????????#設置public為默認區(qū)域 ??
firewall-cmd --get-default-zone ?????????????????#查看默認區(qū)域信息 ??
firewall-cmd --zone=public --add-interface=eth0 ?#將接口eth0加入?yún)^(qū)域public?
#接口相關(guān)?
firewall-cmd --zone=public --remove-interface=eth0 ??????#從區(qū)域public中刪除接口eth0 ??
firewall-cmd --zone=default --change-interface=eth0 ?????#修改接口eth0所屬區(qū)域為default ??
firewall-cmd --get-zone-of-interface=eth0 ???????????????#查看接口eth0所屬區(qū)域 ??
4、用例?
firewall-cmd --query-port=8080/tcp ???#?查詢端口是否開放?
