systemctl使用
systemctl unmask firewalld #执行命令，即可实现取消服务的锁定
systemctl mask firewalld # 下次需要锁定该服务时执行
systemctl start firewalld.service #启动防火墙
systemctl stop firewalld.service #停止防火墙
systemctl reloadt firewalld.service #重载配置
systemctl restart firewalld.service #重启服务
systemctl status firewalld.service #显示服务的状态
systemctl enable firewalld.service #在开机时启用服务
systemctl disable firewalld.service #在开机时禁用服务
systemctl is-enabled firewalld.service #查看服务是否开机启动
systemctl list-unit-files|grep enabled #查看已启动的服务列表
systemctl –failed #查看启动失败的服务列表

firewall-cmd使用
firewall-cmd –state #查看防火墙状态
firewall-cmd –reload #更新防火墙规则
firewall-cmd –state #查看防火墙状态
firewall-cmd –reload #重载防火墙规则
firewall-cmd –list-ports #查看所有打开的端口
firewall-cmd –list-services #查看所有允许的服务
firewall-cmd –get-services #获取所有支持的服务

/usr/lib/firewalld/services

#区域相关
firewall-cmd –list-all-zones #查看所有区域信息
firewall-cmd –get-active-zones #查看活动区域信息
firewall-cmd –set-default-zone=public #设置public为默认区域
firewall-cmd –get-default-zone #查看默认区域信息
firewall-cmd –zone=public –add-interface=eth0 #将接口eth0加入区域public
#接口相关
firewall-cmd –zone=public –remove-interface=eth0 #从区域public中删除接口eth0
firewall-cmd –zone=default –change-interface=eth0 #修改接口eth0所属区域为default
firewall-cmd –get-zone-of-interface=eth0 #查看接口eth0所属区域

用例
firewall-cmd –query-port=8080/tcp # 查询端口是否开放

firewall-cmd –add-port=80/tcp –permanent #永久添加80端口例外(全局)
firewall-cmd –remove-port=80/tcp –permanent #永久删除80端口例外(全局)
firewall-cmd –add-port=65001-65010/tcp –permanent #永久增加65001-65010例外(全局)
firewall-cmd –zone=public –add-port=80/tcp –permanent #永久添加80端口例外(区域public)
firewall-cmd –zone=public –remove-port=80/tcp –permanent #永久删除80端口例外(区域public)
firewall-cmd –zone=public –add-port=65001-65010/tcp –permanent #永久增加65001-65010例外(区域public)

firewall-cmd –reload #重启防火墙(修改配置后要重启防火墙)

打开命令行(管理员权限)，输入
netsh winsock reset
重启电脑即可

一次成功

先安装了nginx+ssl，再安装v2ray，调整配置。

yum -y update
bash <(curl -L -s https://install.direct/go.sh)
systemctl enable v2ray
