## 关闭防火墙 ##

systemctl disable firewalld
    systemctl stop firewalld

## Master上的etcd、kube-apiserver、kube-controller-manager、kube-scheduler服务 ##

### etcd服务 ###

etcd服务作为kubernets集群的主数据库，在安装Kubernets各服务之前需要首先安装和启动。从Github官网下载etcd发布的二进制文件etcd-v3.4.9-linux-amd64，将etcd和etcdctl文件复制到/usr/bin目录。

vim etcd.service

[Unit]
    Description=Etcd Server
    After=network.target
    
    [Service]
    Type=simple
    WorkingDirectory=/var/lib/etcd/
    EnvironmentFile=-/etc/etcd/etcd.conf
    ExecStart=/usr/bin/etcd
    
    [Install]
    WantedBy=multi-user.target

创建etcd数据保存目录/var/lib/etcd/

配置完成的后，通过systemctl start启动etcd服务，同时，使用systemctl enable命令将服务加入开机启动列表

systemctl daemon-reload
    systemctl enable etcd.service
    systemctl start etcd.service

etcd默认将监听http://127.0.0.1:2379地址供客户端连接  
通过etcdctl cluster-health验证etcd是否正确启动
