### V2Ray官方提供了一个在 Linux 服务端 自动化安装脚本。
```
###  V2Ray官方一键脚本
bash <(curl -L -s https://install.direct/go.sh)
```

### 显示官方服务端默认配置(TCP协议vmess)
```

### 修改服务端配置换成UDP协议kcp，先复制上面v2ray配置

```
vim /etc/v2ray/config.json
# Esc键 :set paste  回车 ggdG i shift+Insert Esc键 :wq
```

### 重启v2ray服务端和显示服务器IP
```
systemctl restart v2ray
curl -4 ip.sb
```

### 方法1: 客户端 vmess协议导入，再修改成实际服务器IP
```
vmess://ew0KICAidiI6ICIyIiwNCiAgInBzIjogIlYyUmF5IiwNCiAgImFkZCI6ICIxODguMTg4LjE4OC4xODgiLA0KICAicG9ydCI6ICI4MDAwIiwNCiAgImlkIjogIjUyMDU1MzUyLTM0ZTgtNDUzYy1iNmY2LTIyZWFjNjMwYjZlMSIsDQogICJhaWQiOiAiMTYiLA0KICAibmV0IjogImtjcCIsDQogICJ0eXBlIjogInNydHAiLA0KICAiaG9zdCI6ICIiLA0KICAicGF0aCI6ICIiLA0KICAidGxzIjogIiINCn0=
```
### 方法2: 添加[vmess]服务器-->导入配置文件-->导入服务端配置-->再修改成实际服务器IP
- 导入有个Bug，伪装类型不会识别，使用上面的mKcp配置，伪装类型srtp要按实际设置

### 下载v2ray for Windows 客户端地址如果被墙，可以先用vps下载
### 借用vps中转，开临时网页服务器 访问 http://1.2.3.4:8000  (1.2.3.4实际vps的ip)
```
wget https://github.com/2dust/v2rayN/releases/download/2.22/v2rayN-Core.zip
python -m SimpleHTTPServer 8000
```
