sudo systemctl start caddy sudo systemctl status caddy
看到绿色的Active,说明启动成功
安装V2ray
核心的东西来了!!!,使用官网的一键安装脚本。首先切换到root,并在root下新建文件夹保存脚本
1 2 3 4 5 6 7
sudo su cd ~ mkdir scripts cd ./scripts curl -L -s https://install.direct/go.sh > v2ray.sh chmod +x v2ray.sh bash v2ray.sh
使用crontab每周运行该脚本,以定期更新v2ray,在末尾追加以下一行
1 2 3 4
crontab -e 21 10 * * sun /bin/bash /root/scripts/v2ray.sh
