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

#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
EOFcat <<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

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

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

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- master3control-plane: - master1- master2- master3worker:- node1controlPlaneEndpoint:## Internal loadbalancer for apiservers ## internalLoadbalancer: haproxy# 阿里云的负载均衡domain: lb.kubesphere.localaddress: "1xx.xx.xx.xx"port: 6443kubernetes:version: v1.22.12clusterName: cluster.localautoRenewCerts: truecontainerManager: dockeretcd:type: kubekeynetwork:plugin: calicokubePodsCIDR: 10.233.64.0/18kubeServiceCIDR: 10.233.0.0/18## multus support. https://github.com/k8snetworkplumbingwg/multus-cnimultusCNI:enabled: falseregistry:privateRegistry: ""namespaceOverride: ""registryMirrors: []insecureRegistries: []addons:- name: nfs-clientnamespace: kube-systemsources:chart:name: nfs-client-provisionerrepo: https://charts.kubesphere.io/mainvaluesFile: /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

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

./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）

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
