官方安装脚本：

bash <(curl -L -s https://install.direct/go.sh)

报错：

Updating software repo /dev/fd/63: line 119: apt-get: command not
found Installing daemon /dev/fd/63: line 124: apt-get: command not
found Install daemon fail, please install it manually

问题就是安装脚本在创建守护服务的时候不支持CentOS6

解决办法

将下述代码保存为/etc/init.d/v2ray，并添加执行权限。

    #!/bin/sh
    #

开机启动：
加入开机启动，开启服务，问题彻底解决

chmod a+x /etc/init.d/v2ray
chkconfig v2ray on
service v2ray start

记得防火墙放行服务端口

查看配置

cat /etc/v2ray/config.json
