５步完成etcd单机集群部署

## 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 ```shell #!/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 ```shell chmod +x start.sh ./start.sh ``` ## 五、检验集群是否启动成功
