配置和启动Kubernetes服务

• 安装etcd服务

1. 下载安装包

   wget https://github.com/coreos/etcd/releases/download/v3.1.3/etcd-v3.1.3-linux-amd64.tar.gz

   解压后将可执行文件复制到/urs/bin目录

   tar xzvf etcd-v3.1.3-linux-amd64.tar.gz 
   
   cd etcd-v3.1.3-linux-amd64 && cp etcd* /usr/bin/

   配置开机启动etcd.service

   vi /usr/lib/systemd/system/etcd.service

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

2. 创建工作目录

   mkdir /var/lib/etcd

3. 启动并加入开机列表

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