toxiproxy 安裝試用

備註：

   其實是一個代理工具，可是又不是簡單的進行代理（tcp，能夠配置策略，toxics 實現延遲，模擬故障，

   對於這個你們可能瞭解的就是netflix 公司的chaos monkey，實際的使用你們能夠參考相關文章，本次只是

   對於toxiproxy 的簡單安裝試用，同時這個工具能夠放到你們持續集成工具集中。

 

1. 安裝（爲了簡單同時安裝了server 以及cli）

// 下載地址
wget https://github.com/Shopify/toxiproxy/releases/download/v2.1.2/toxiproxy-server-linux-amd64 
wget https://github.com/Shopify/toxiproxy/releases/download/v2.1.2/toxiproxy-cli-linux-amd64 

// 配置安裝（實際上就是更名稱，拷貝文件）
mv toxiproxy-cli-linux-amd64  toxiproxy-cli
mv toxiproxy-server-linux-amd64  toxiproxy-server
chmod +x *
cp * /usr/bin/

2. 試用（爲了測試安裝了redis ）

// redis 環境準備
yum install -y redis 
systemctl restart redis

// 啓動toxiproxy (後臺進程)
nohup toxiproxy-server  -host "0.0.0.0" &

// 代理 redis
toxiproxy-cli create myredis -l 0.0.0.0:26379 -u 127.0.0.1:6379

// 配置toxic(讓redis 處理延遲1秒)
toxiproxy-cli toxic add myredis -t latency -a latency=1000

// 鏈接測試
redis-cli -h XXXXXX -p 26379

  測試效果
