Shell脚本快速部署Kubernetes(K8S v1.1版本)集群系统
提醒：即使按照本篇文章一步一步做，也不一定部署成功。原因你懂得！如果失败，也建议你仔细看看脚本内容，从中寻找解决办法。同时，相信你也会从脚本中获取到其他有价值的信息。 实验环境： 操作系统：Ubuntu14.04_x64 master：192.168.1.150 minion01: 192.168.1.151 容器网段：172.17.1.0/24 minion02: 192.168.1.152 容器网段：172.17.2.0/24 安装包下载： etcd：http://pan.baidu.com/s/1c1wITMw kubernetes：http://pan.baidu.com/s/1kUoxgYb 相关脚本下载：http://pan.baidu.com/s/1o7nEaca 脚本说明： config_ssh_root_remote.sh #配置root SSH登录（默认ubuntu系统禁止root SSH登录） ssh_keypair_auth.sh #配置master主机与minion主机SSH免交互认证 kubernetes-install.sh #安装kubernetes的master端与minion端 config_gre_channel.sh #配置两台Docker主机容器实现跨主机访问（OVS） 安装步骤（请按照步骤做）： 1）在minion主机root权限开启root允许SSH远程登录 操作命令：$ sudo bash config_ssh_root_remote.sh 脚本内容：$ cat config_ssh_root_remote.sh 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 #!/bin/bash #Description:configurationrootaccountsshremotelogin if [$USER!= "root" ];
