4、配置文件
采用VMess-TCP模式

vi /usr/local/etc/xray/config.json
{
    "log": {
        "access": "/var/log/xray/access.log",
        "error": "/var/log/xray/error.log",
        "loglevel": "info"
    },
    "routing": {
        "domainStrategy": "AsIs",
        "rules": [
            {
                "type": "field",
                "ip": [
                    "geoip:private"
                ],
                "outboundTag": "block"
            }
        ]
    },
    "inbounds": [
        {
            "listen": "xxx.xxx.xxx.xxx",
            "port": 12340,
            "protocol": "vmess",
            "settings": {
                "clients": [
                    {
                        "id": "a4ee4ff1-2c5c-421b-aa3d-b8a748638d84"
                    }
                ]
            },
            "streamSettings": {
                "network": "tcp"
            }
        }
    ],
    "outbounds": [
        {
            "protocol": "freedom",
            "tag": "direct"
        },
        {
            "protocol": "blackhole",
            "tag": "block"
        }
    ]
}

5、创建日志文件
touch /var/log/xray/access.log
touch /var/log/xray/error.log
chmod 777 -R /var/log/xray

6、客户端使用v2rayN工具配置
TCP模式，伪装类型选none
