Windows下安装Etcd集群及etcd-viewer

前言

最近在研究etcd，用于解决一个服务的主备切换的问题，工欲善其事必先利其器，先把本地所需的所有环境搭建好。涉及到本地Windows环境的etcd集群的搭建，以及etcd可视化web工具etcd-viewer的搭建。etcd使用go语言开发的，在Windows平台上最终编译成了可执行的exe文件，部署非常容易。

安装etcd集群

下载etcd

下载地址：https://github.com/etcd-io/etcd/releases

选择对应的版本下载即可，Windows版本解压后文件目录如下：

在同级目录分别创建如下三个启动脚本：

• cluster-2380.cmd ```powershell @echo off echo Starting etcd-cluster-1: 2380 “../etcd.exe” —name etcd01 ^ —data-dir ../data/etcd01 ^ —advertise-client-urls http://127.0.0.1:2379 ^ —listen-client-urls http://127.0.0.1:2379 ^ —listen-peer-urls http://127.0.0.1:2380 ^ —initial-advertise-peer-urls http://127.0.0.1:2380 ^ —initial-cluster-token etcd-cluster-1 ^ —initial-cluster etcd01=http://127.0.0.1:2380,etcd02=http://127.0.0.1:2381,etcd03=http://127.0.0.1:2382 ^ —initial-cluster-state new

pause

- cluster-2381.cmd
```powershell
@echo off
echo Starting etcd-cluster-1: 2381
"../etcd.exe" --name etcd02 ^
--data-dir ../data/etcd02 ^
--advertise-client-urls http://127.0.0.1:3379 ^
--listen-client-urls http://127.0.0.1:3379 ^
--listen-peer-urls http://127.0.0.1:2381 ^
--initial-advertise-peer-urls http://127.0.0.1:2381 ^
--initial-cluster-token etcd-cluster-1 ^
--initial-cluster etcd01=http://127.0.0.1:2380,etcd02=http://127.0.0.1:2381,etcd03=http://127.0.0.1:2382 ^
--initial-cluster-state new
pause

• cluster-2382.cmd ```powershell @echo off echo Starting etcd-cluster-1: 2382 “../etcd.exe” —name etcd03 ^ —data-dir ../data/etcd03 ^ —advertise-client-urls http://127.0.0.1:4379 ^ —listen-client-urls http://127.0.0.1:4379 ^ —listen-peer-urls http://127.0.0.1:2382 ^ —initial-advertise-peer-urls http://127.0.0.1:2382 ^ —initial-cluster-token etcd-cluster-1 ^ —initial-cluster etcd01=http://127.0.0.1:2380,etcd02=http://127.0.0.1:2381,etcd03=http://127.0.0.1:2382 ^ —initial-cluster-state new

pause

- start-cluster.cmd
```powershell
@echo off
echo Starting Cluster: 2381-2383
pushd %~dp0\Cluster
@start "Etcd (Cluster): 2380" /min cluster-2380.cmd
@start "Etcd (Cluster): 2381" /min cluster-2381.cmd
@start "Etcd (Cluster): 2382" /min cluster-2382.cmd
popd

然后在同级目录下创建好对应的data-dir，如/data/etcd01、/data/etcd02、/data/etcd03,创建好后,依次启动cluster-2380.cmd、cluster-2381.cmd、cluster-2382.cmd三个脚本，然后使用.\etcdctl.exe member list,当输出如下信息时，代表集群创建成功了。

 .\etcdctl.exe member list

如果出现如下的信息，代表可能etcd启动过程阻塞住了，只要在cmd窗口里按下回车键就ok了E:\runtime\

E:\runtime\etcd-v3.3.12-windows-amd64>etcdctl.exe member list
client: etcd cluster is unavailable or misconfigured; error #0: dial tcp 127.0.0.1:4001: connectex: No connection could be made because the target machine actively refused it.
; error #1: client: endpoint http://127.0.0.1:2379 exceeded header timeout

安装etcd-vieweretcd-viewe

etcd-vieweretcd-viewer是一款同时支持v2和v3版本接口的etcd可视化web服务，使用java开发，底层基于jetcd和Apache cxf。etcd-viewer也是etcd官方推荐的一个可视化组件

项目地址：https://github.com/nikfoundas/etcd-viewer

1. etcd-viewer已经提供了docker镜像，并上传到了中央仓库，使用如下docker脚本可以直接运行：

   docker run -d -p 8080:8080 nikfoundas/etcd-viewer

2. 或者下载源码后，导入到IDEA，使用mvn jetty:run运行3、打包成war包后，丢到tomcat中运行

3. 安装成功后，界面如下

etcd-latest.zip
