KubeSphere官网

服务器信息

name	ip
master	192.168.40.153
node1	192.168.40.161
node2	192.168.40.162

准备工作 执行下列代码，在每一台服务器上

yum update -y 
yum install -y chrony 
systemctl enable chronyd
systemctl start chronyd
timedatectl set-ntp true
timedatectl set-timezone Asia/Shanghai
chronyc activity -v
iptables -F
systemctl status firewalld
systemctl stop firewalld
systemctl disable firewalld
yum install openssl openssl-devel -y
yum install socat -y
yum install epel-release -y
yum install conntrack-tools -y

生成配置文件

export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | VERSION=v1.0.1 sh -
chmod +x kk
./kk create config --with-kubesphere v3.0.0
vim config-sample.yaml

这时在当前目录下就创建一个config-sample.yaml
我们使用vim 将配置文件修改为

apiVersion: kubekey.kubesphere.io/v1alpha1
kind: Cluster
metadata:
  name: sample
spec:
  hosts:
  - {name: master, address: 192.168.40.153, internalAddress: 192.168.40.153, user: root, password: '8'}
  - {name: node1, address: 192.168.40.161, internalAddress: 192.168.40.161, user: root, password: '8'}
  - {name: node2, address: 192.168.40.162, internalAddress: 192.168.40.162, user: root, password: '8'}
  roleGroups:
    etcd:
    - master
    master: 
    - master
    worker:
    - master
    - node1
    - node2
  controlPlaneEndpoint:
    domain: lb.kubesphere.local
    address: ""
    port: "6443"
  kubernetes:
    version: v1.17.9
    imageRepo: kubesphere
    clusterName: cluster.local
  network:
    plugin: calico
    kubePodsCIDR: 10.233.64.0/18
    kubeServiceCIDR: 10.233.0.0/18
  registry:
    registryMirrors: []
    insecureRegistries: []
  addons: []

apiVersion: installer.kubesphere.io/v1alpha1
kind: ClusterConfiguration
metadata:
  name: ks-installer
  namespace: kubesphere-system
  labels:
    version: v3.0.0

vim保存退出 :wq!

./kk create cluster -f config-sample.yaml //开始安装

整个过程大概20分钟

kubectl patch users admin -p '{"spec":{"password":"123456"}}' --type='merge' && kubectl annotate users admin iam.kubesphere.io/password-encrypted- 

启用 kubectl 自动补全

yum -y install epel-release
yum install bash-completion bash-completion-extras -y
locate bash_completion.sh
updatedb
source /etc/profile.d/bash_completion.sh
logout //登出后重新登录
echo 'source <(kubectl completion bash)' >>~/.bashrc
kubectl completion bash >/etc/bash_completion.d/kubectl
