教育实施步骤

表1 etcd集群软件安装
在master1上安装cfssl	wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64 chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 mv cfssl_linux-amd64 /usr/local/bin/cfssl mv cfssljson_linux-amd64 /usr/local/bin/cfssljson
安装etcd二进制文件	# 创建目录 mkdir -p /data/etcd/bin # 下载 cd /tmp wget https://storage.googleapis.com/etcd/v3.3.25/etcd-v3.3.25-linux-amd64.tar.gz tar zxf etcd-v3.3.25-linux-amd64.tar.gz cd etcd-v3.3.25-linux-amd64 mv etcd etcdctl /data/etcd/bin/
创建ca证书，客户端，服务端，节点之间的证书	Etcd属于server ,etcdctl 属于client，二者之间通过http协议进行通信。创建目录创建ca证书生成客户端证书 cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=client client.json \| cfssljson -bare client - 生成server，peer证书 cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=server etcd.json \| cfssljson -bare server cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=peer etcd.json \| cfssljson -bare peer 将master01的/data/etcd/ssl目录同步到master02和master03上 scp -r /data/etcd etcd2:/data/etcd scp -r /data/etcd etcd3:/data/etcd
etcd systemd配置文件	vim /usr/lib/systemd/system/etcd.service 三台主机配置不一样用的时候把注释尽量删除
启动etcd集群	systemctl daemon-reload systemctl enable etcd systemctl start etcd systemctl status etcd
