最近把自己的膝上型電腦安裝成ubuntu18.04作業系統，為了更方便的查詢文件，所以需要配置一下機場(v2ray)的客戶端方便上google查詢資料，以下是配置步驟：

1、下載並執行一鍵指令碼：

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

這個是安裝v2ray的一鍵指令碼

#!/bin/bash

# This file is accessible as https://install.direct/go.sh
# Original source is located at github.com/v2ray/v2ray-core/release/install
 
-release.sh

# If not specify, default meaning of return value:
# 0: Success
# 1: System error
# 2: Application error
# 3: Network error
