etcd叢集部署文檔

1.部署的伺服器ip位址
   172.16.0.151
   172.16.0.173
   172.16.0.220
2.etcd版本
   wget  https://github.com/etcd-io/etcd/releases/download/v3.5.0/etcd-v3.5.0-linux-amd64.tar.gz
3.三台伺服器安裝目錄 /data/ 
4.啟動腳本
   cd /data/etcd-v3.5.0
   [root@im-03 etcd-v3.5.0]cat etcd.sh
   #For each machine
   TOKEN=my-etcd-token-1
   CLUSTER_STATE=new

   CLUSTER=${NAME_1}=http://${HOST_1}:2380,${NAME_2}=http://${HOST_2}:2380,${NAME_3}=http://${HOST_3}:2380

   # For node 1
   THIS_NAME=${NAME_1}
   THIS_IP=${HOST_1}
   /data/etcd-v3.5.0/etcd --data-dir=/data/etcd-v3.5.0/data.etcd --name ${THIS_NAME} \

   --initial-cluster ${CLUSTER} \
   --initial-cluster-state ${CLUSTER_STATE} \
   --initial-cluster-token ${TOKEN} > /data/etcd-v3.5.0/etcd.out 2>&1 &

5.三台伺服器分别執行etcd.sh賦予執行權限并啟動
   chmod +x /data/etcd-v3.5.0/etcd.sh
   /data/etcd-v3.5.0/etcd.sh
6.三台伺服器分别執行建立軟連接配接
[root@im-05 etcd-v3.5.0]# ln -s /data/etcd-v3.5.0/etcd /usr/local/bin/etcd
[root@im-05 etcd-v3.5.0]# ln -s /data/etcd-v3.5.0/etcdctl /usr/local/bin/etcdctl
[root@im-05 etcd-v3.5.0]# ln -s /data/etcd-v3.5.0/etcdutl /usr/local/bin/etcdutl
7./usr/local/bin/加入環境變量
    vim /etc/profile
   export PATH=/usr/local/bin/:$PATH
   
8. 執行指令 source /etc/profile
