下载安装包：
~]# tar xf etcd-v3.1.20-linux-amd64.tar.gz -C /opt/
~]# ln -s /opt/etcd-v3.1.20-linux-amd64 /opt/etcd      ## 便于后期升级做软连
~]# useradd -s /sbin/nologin -M etcd           ## 添加运行etcd普通用户
~]# mkdir -p /opt/etcd/certs /data/etcd /data/logs/etcd-server     ## 创建数据目录以及日志目录

~]# vi /opt/etcd/etcd-server-startup.sh

安装管理工具supervisor

~]# yum install supervisor -y
~]# systemctl start supervisord 
~]# systemctl enable supervisord

supervisorctl update
etcd-server-7-12: added process group

备注：
另外两台服务器操作一样，拷贝证书，配置文件，安装管理工具并加入进去就可以了。

~]# supervisorctl status

验证集群是否正常：

etcd]# ./etcdctl member list
