我是靠谱客的博主贤惠大门，这篇文章主要介绍etcd静态集群部署(Centos 3节点)，现在分享给大家，希望可以做个参考。

当确定集群的成员个数及其信息，可以使用静态模式(Static)部署集群，具体步骤如下：

一、机器信息

hostname	ip	系统版本
infra0	172.17.0.2	CentOS Linux release 7.4.1708 (Core)
infra1	172.17.0.3	CentOS Linux release 7.4.1708 (Core)
infra2	172.17.0.4	CentOS Linux release 7.4.1708 (Core)

二、下载etcd二进制包

wget https://github.com/coreos/etcd/releases/download/v3.2.10/etcd-v3.2.10-linux-amd64.tar.gz
tar -xf etcd-v3.2.10-linux-amd64.tar.gz
sudo mv etcd-v3.2.10-linux-amd64/etcd* /usr/local/bin/
etcd --version 
--------------------------------
etcd Version: 3.2.10
Git SHA: 694728c
Go Version: go1.8.5
Go OS/Arch: linux/amd64
--------------------------------

etcdctl --version
------------------------------
etcdctl version: 3.2.10
API version: 2-
------------------------------

三、启动节点

1.infra0节点执行命令

mkdir -p /data/etcd/data_dir
nohup etcd --name infra0 --data-dir /data/etcd/data_dir 
  --initial-advertise-peer-urls http://${NODE_INFRA0_IP}:2380 
  --listen-peer-urls http://${NODE_INFRA0_IP}:2380 
  --listen-client-urls http://${NODE_INFRA0_IP}:2379,http://127.0.0.1:2379 
  --advertise-client-urls http://${NODE_INFRA0_IP}:2379 
  --initial-cluster-token etcd-cluster-1 
  --initial-cluster infra0=http://${NODE_INFRA0_IP}:2380,infra1=http://${NODE_INFRA1_IP}:2380,infra2=http://${NODE_INFRA2_IP}:2380 
  --initial-cluster-state new >> /data/etcd/etcd.log 2>&1 &

2.infra1节点执行命令

  --initial-cluster-state new >> /data/etcd/etcd.log 2>&1 &

nohup etcd --name infra2 --data-dir /data/etcd/data_dir 
  --initial-advertise-peer-urls http://${NODE_INFRA2_IP}:2380 
  --listen-peer-urls http://${NODE_INFRA2_IP}:2380

  --initial-cluster infra0=http://${NODE_INFRA0_IP}:2380,infra1=http://${NODE_INFRA1_IP}:2380,infra2=http://${NODE_INFRA2_IP}:2380 
  --initial-cluster-state new >> /data/etcd/etcd.log 2>&1 &

四、检查集群状态

etcdctl cluster-health #在任意节点执行

member 9198227ac1a2c055 is healthy: got healthy result from http://172.17.0.3:2379
member 983274ac8c0149ec is healthy: got healthy result from http://172.17.0.2:2379
member ab3fbede047aa1ac is healthy: got healthy result from http://172.17.0.4:2379
cluster is healthy
