V2ray官方一键安装脚本(2021/10)

v2ray一键安装脚本（21/10新）：

之前一直用SSR，但最近两天发现SSR老是自动掉，然后就重新做了个vmess
记录以下过程，以免以后要用到的时候找不到了

执行官方安装脚本：

apt-get install -y curl
bash <(curl -L https://raw.githubusercontent.com/v2fly/fhs-install-v2ray/master/install-release.sh)

编辑配置文件：

# 这是我使用的配置文件，你可以拿去做模板，然后自己修改
wget --no-check-certificate https://teadan.com/all_bash/v2_s.json  -O -> /usr/local/etc/v2ray/config.json
# 下载的配置文件放在     /usr/local/etc/v2ray/config.json
# 其中    port：是你客户端连接的端口
# id：是你客户端连接时用的UUID，这个你网上搜以下，‘‘随机生成UUID’，就可以生成了

重启服务：

# 设置开机自自动
systemctl enable v2ray.service
# 如果你不想开机自启动了，可以删除
systemctl disable v2ray.service
# 重启v2ray服务
service v2ray restart

常用命令：

service v2ray restart   # 重启
service v2ray force-reload  # 强制重启
service v2ray start   # 启动
service v2ray stop   # 停止
service v2ray status  # 状态查看
service v2ray reload   # 重装

测试V2Ray配置文件：

/usr/local/bin/v2ray -test -config /usr/local/etc/v2ray/config.json

安装成功：
