1. 准备三台centos7机子，机子的ip分别为192.168.110.128,192.168.110.129,192.168.110.130，其中128为master节点，129为node1，130为node2，修改主机名并关闭三台机子的防火墙

hostnamectl set-hostname master
hostnamectl set-hostname node1
hostnamectl set-hostname node2

systemctl stop firewalld
systemctl disable firewalld

2. 在master机子上，下载KubeSphere 2.1.1安装包，并修改kubesphere-all-v2.1.1/conf/hosts.ini文件

curl -L https://kubesphere.io/download/stable/v2.1.1 > installer.tar.gz \
&& tar -zxf installer.tar.gz && cd kubesphere-all-v2.1.1/conf

由于我们用的用户名都是root，密码都是123456，则下面的配置即可

master ansible_connection=local  ip=192.168.110.128
node1  ansible_host=192.168.110.129  ip=192.168.110.129  ansible_ssh_pass=123456
node2  ansible_host=192.168.110.130  ip=192.168.110.130  ansible_ssh_pass=123456

如果不是root用户，只是又root权限的话，则需要按下面的配置

master ansible_connection=local  ip=192.168.0.5  ansible_user=ubuntu  ansible_become_pass=Qcloud@123
node1  ansible_host=192.168.0.6  ip=192.168.0.6  ansible_user=ubuntu  ansible_become_pass=Qcloud@123
node2  ansible_host=192.168.0.8  ip=192.168.0.8  ansible_user=ubuntu  ansible_become_pass=Qcloud@123

3. 安装
   安装前先配置镜像加速，修改common.yaml文件

docker_registry_mirrors:
  - https://zoo2pivc.mirror.aliyuncs.com

最好是先将镜像拉取下来，记得三台机子都需要拉取，所以可以事先每台机子都安装好docker
首先新建一个叫images的文件，将需要下载的镜像写入里面

然后执行下面两句，也就是从qing容器仓库中拉取镜像

docker login -u guest -p guest dockerhub.qingcloud.com
for line in `cat images`; do docker pull $line; done

镜像拉取好了以后，执行kubesphere-all-v2.1.1/scripts/install.sh
