ETCD初体验

1. 安装 

1.1  下载

https://github.com/etcd-io/etcd/releases

找到对应的版本下载下来 解压到指定目录下 

这里我创建   /home/etcd目录 文件解压在这里 

1.2 创建目录

mkdir node1 node2 node3

1.3 创建shell脚本

vim node1/start.sh

/home/etcd/etcd-v3.5.0-linux-amd64/etcd --name infra1 --initial-advertise-peer-urls http://127.0.0.1:2381 \
--listen-peer-urls http://127.0.0.1:2381 \
--listen-client-urls http://127.0.0.1:2379 \
--advertise-client-urls http://127.0.0.1:2379 \
--initial-cluster-token etcd-cluster-1 \
--initial-cluster infra1=http://127.0.0.1:2381,infra2=http://127.0.0.1:2382,infra3=http://127.0.0.1:2383 \
--initial-cluster-state new

vim node2/start.sh

/home/etcd/etcd-v3.5.0-linux-amd64/etcd --name infra2 --initial-advertise-peer-urls http://127.0.0.1:2382 \
  --listen-peer-urls http://127.0.0.1:2382 \
    --listen-client-urls http://127.0.0.1:2378 \
          --advertise-client-urls http://127.0.0.1:2378 \
            --initial-cluster-token etcd-cluster-1 \
                  --initial-cluster infra1=http://127.0.0.1:2381,infra2=http://127.0.0.1:2382,infra3=http://127.0.0.1:2383 \
                    --initial-cluster-state new

vim node3/start.sh

/home/etcd/etcd-v3.5.0-linux-amd64/etcd --name infra3 --initial-advertise-peer-urls http://127.0.0.1:2383 \
  --listen-peer-urls http://127.0.0.1:2383 \
    --listen-client-urls http://127.0.0.1:2377 \
          --advertise-client-urls http://127.0.0.1:2377 \
            --initial-cluster-token etcd-cluster-1 \
                  --initial-cluster infra1=http://127.0.0.1:2381,infra2=http://127.0.0.1:2382,infra3=http://127.0.0.1:2383 \
                    --initial-cluster-state new

1.4 启动 

我这里使用的nohup 启动 有时间的话可以安装supervisor管理

nohup sh /home/etcd/node1/start.sh &

nohup sh /home/etcd/node2/start.sh &

nohup sh /home/etcd/node3/start.sh &

1.5 检查集群是否启动成功

 /home/etcd/etcd-v3.5.0-linux-amd64/etcdctl member list
