K8s之二进制安装高可用集群

2.在每个节点安装依赖工具
apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y
# 安装python2
apt-get install python2.7
# Ubuntu16.04可能需要配置以下软连接
ln -s /usr/bin/python2.7 /usr/bin/python

3.部署节点安装ansible以及准备ssh免密登录
# 附上脚本
!/bin/bash
#目标主机列表

10.0.0.141
10.0.0.142
10.0.0.143

for node in ${IP};do
    sshpass -p 1  ssh-copy-id ${node} -o StrictHostKeyChecking=no
    if [ $? -eq 0 ];then
        echo "${node} 秘钥copy完成"
  else
        echo "${node} 秘钥copy失败"
