５步完成 etcd 单机集群部署

[xmge]

一、下载 etcd

相关版本在： https://github.com/etcd-io/etcd/releases/

这里以 ubuntu x64 举例:

wget https://github.com/etcd-io/etcd/releases/download/v3.4.0-rc.3/etcd-v3.4.0-rc.3-linux-amd64.tar.gz

二、创建如下目录结构

三、新增三个配置文件

etcd1/etcd.conf 配置文件:

name: etcd-1
data-dir: /home/xmge/show/etcd_cluster/etcd1/data   // 需要指定自己目录下的位置
listen-client-urls: http://0.0.0.0:2379
advertise-client-urls: http://127.0.0.1:2379
listen-peer-urls: http://0.0.0.0:2380
initial-advertise-peer-urls: http://127.0.0.1:2380
initial-cluster: etcd-1=http://127.0.0.1:2380,etcd-2=http://127.0.0.1:2480,etcd-3=http://127.0.0.1:2580
initial-cluster-token: etcd-cluster-my
initial-cluster-state: new

etcd2/etcd.conf 配置文件:

name: etcd-2
data-dir: /home/xmge/show/etcd_cluster/etcd2/data   // 需要指定自己目录下的位置
listen-client-urls: http://0.0.0.0:2479
advertise-client-urls: http://127.0.0.1:2479
listen-peer-urls: http://0.0.0.0:2480
initial-advertise-peer-urls: http://127.0.0.1:2480
initial-cluster: etcd-1=http://127.0.0.1:2380,etcd-2=http://127.0.0.1:2480,etcd-3=http://127.0.0.1:2580
initial-cluster-token: etcd-cluster-my
initial-cluster-state: new

etcd3/etcd.conf 配置文件：

name: etcd-3
data-dir: /home/xmge/show/etcd_cluster/etcd3/data   // 需要指定自己目录下的位置
listen-client-urls: http://0.0.0.0:2579
advertise-client-urls: http://127.0.0.1:2579
listen-peer-urls: http://0.0.0.0:2580
initial-advertise-peer-urls: http://127.0.0.1:2580
initial-cluster: etcd-1=http://127.0.0.1:2380,etcd-2=http://127.0.0.1:2480,etcd-3=http://127.0.0.1:2580
initial-cluster-token: etcd-cluster-my
initial-cluster-state: new

四、新增启动脚本 start.sh 并启动

#!/bin/bash

CRTDIR=$(pwd)
servers=("etcd1" "etcd2" "etcd3")


for server in ${servers[@]}
do
        cd ${CRTDIR}/$server
        nohup ./etcd --config-file=etcd.conf &
        echo $?
done

启动集群

chmod +x start.sh
./start.sh

五、检验集群是否启动成功

[chennqqi]

一步搞定 yum installl.或者 docker run...

[zunceng]

装好了 k8s web UI 按一下 或者 helm install 了解一下

[xmge]

@zunceng 哈哈哈，ok

[xmge]

@chennqqi 看到啦，，

[xmge]

果然可以抛砖引玉。。。。
