安全传输

当要和服务器安全传输时，可以使用v2fly。

1. 官网

2. 文档

js 生成UUID

crypto.randomUUID();

服务端安装

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

启动

启动 V2Ray:
# systemctl start v2ray

停止 V2Ray
# systemctl stop v2ray

查看服务状态
# service v2ray status

设置开机自启动 V2Ray:
# systemctl enable v2ray

配置

1. 修改配置文件：

vim /usr/local/etc/v2ray/config.json

2. vmess 配置如下

{
  "inbounds": [
    {
      "port": 9901,
      "protocol": "vmess",
      "settings": {
        "clients": [
          {
            "id": "使用生成的UUID",
            "alterId": 0,
            "security": "auto",
            "level": 0
          }
      ]
      }
    },
  ],
  "outbounds": [
    {
      "protocol": "freedom"
    }
  ]
}

配置文档 : https://www.v2fly.org/config/protocols/vless.html#outboundconfigurationobject

3. 开放端口, 阿里云还需要开启安全组的端口，并重启服务器

# centos系统 开了防火墙才使用
firewall-cmd --zone=public --add-port=9900-9999/tcp --permanent
firewall-cmd --zone=public --add-port=9900-9999/udp --permanent

# 刷新规则
firewall-cmd --reload

4. 启动成功的样子

# systemctl status v2ray
● v2ray.service - V2Ray Service
   Loaded: loaded (/etc/systemd/system/v2ray.service; disabled; vendor preset: enabled)
   Active: active (running) since Sun 2020-08-16 23:17:13 CST; 41min ago

    Tasks: 6 (limit: 2359)
