阿里云上kubesphere安装配置 - 使用阿里云负载均衡

教程参考

https://www.kubesphere.io/zh/docs/v3.3/installing-on-linux/public-cloud/install-kubesphere-on-ali-ecs/

环境配置

关闭防火墙
关闭selinux
关闭swap分区
时间同步
hosts解析
内核参数设置
检查DNS
安装ipvs
安装依赖组件
安装、设置docker

每台机器都需要操作

shell 复制代码

#安装工具
yum -y install net-tools

# 如果下载不行，设置一个repo
# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*


##关闭防火墙
systemctl   stop     firewalld.service
systemctl   disable   firewalld.service


##时间同步
yum install ntpdate -y
ntpdate  pool.ntp.org
timedatectl set-timezone Asia/Shanghai


# 将 SELinux 设置为 permissive 模式（相当于将其禁用）
sudo setenforce 0
sudo sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config


#关闭swap
swapoff -a  
sed -ri 's/.*swap.*/#&/' /etc/fstab


#允许 iptables 检查桥接流量
cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
br_netfilter
EOF


cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sudo sysctl --system

安装Docker

shell 复制代码

sudo yum remove docker*
sudo yum install -y yum-utils


#配置docker的yum地址
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo



#安装指定版本
sudo yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7 containerd.io-1.4.6


#安装 
sudo yum install -y socat conntrack nfs-utils


# 启动&开机启动docker
systemctl enable docker --now


# docker加速配置
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://m7qysq7c.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

完成后可以制作镜像

安装实例选择 k8s_base_image_2，已经完成部分设置

首次安装-选取一台master

shell 复制代码

export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.7 sh -
chmod +x kk
./kk create config --with-kubesphere v3.3.2 --with-kubernetes v1.22.12 -f config-sample.yaml

修改部分配置

config.yaml

yaml 复制代码

apiVersion: kubekey.kubesphere.io/v1alpha2
kind: Cluster
metadata:
  name: sample
spec:
  hosts:
  - {name: master1, address: 172.31.0.239, internalAddress: 172.31.0.239, user: root, password: "Hailiao$123"}
  - {name: master2, address: 172.31.0.237, internalAddress: 172.31.0.237, user: root, password: "Hailiao$123"}
  - {name: master3, address: 172.31.0.238, internalAddress: 172.31.0.238, user: root, password: "Hailiao$123"}
  - {name: node1, address: 172.31.0.243, internalAddress: 172.31.0.243, user: root, password: "Hailiao$123"}
  roleGroups:
    etcd:
    - master1
    - master2
    - master3
    control-plane: 
    - master1
    - master2
    - master3
    worker:
    - node1
  controlPlaneEndpoint:
    ## Internal loadbalancer for apiservers 
    ## internalLoadbalancer: haproxy

    ## multus support. https://github.com/k8snetworkplumbingwg/multus-cni
    multusCNI:
      enabled: false
  registry:
    privateRegistry: ""
    namespaceOverride: ""
    registryMirrors: []

  addons:
  - name: nfs-client
    namespace: kube-system
    sources:
      chart:
        name: nfs-client-provisioner
        repo: https://charts.kubesphere.io/main
        valuesFile: /root/nfs-client.yaml

没有全部复制，主要是完成了nfs初始化使用nas

nfs-client.yaml

yaml 复制代码

nfs:
  server: "xxx.nas.aliyuncs.com"    # 阿里云Nas地址.
  path: "/new_ks_data"    # Replace the exported directory with your own.
storageClass:
  defaultClass: true

运行安装

复制代码

./kk create cluster -f config.yaml

选择这个镜像后，只需要设置hostname和hosts

每台机器使用内网ip互通

每台机器配置自己的hostname 每个机器分别执行 hostnamectl set-hostname xxx （node1～6）

shell 复制代码

hostnamectl set-hostname node1  # node1 就是对应的主机名称

vim /etc/hosts

# 添加hosts信息
172.31.0.239   master1
172.31.0.237   master2
172.31.0.238   master3
172.31.0.243   node1
# 对应添加更多node主机名称
