kubernetes(k8s)+kubesphere部署
查看执行情况kubectl get pods --all-namespaces所有状态为Running。2.5> 在其他的分支节点执行(k8s-node1 k8s-node2)多执行几次 保证删除干净 如果master 卸载不了 重启机器再尝试删除。NFS_SERVER 设置为安装nfs服务的服务器ip地址。volumes中的nfs同样需要配置对应的nfs环境信息。NFS_PATH 即安装nfs服

1.7.4 配置 docker 加速器(自己去阿里云镜像加速器粘贴 下面是例子 不一定好用)
1.7.5 动 docker & 设置 docker 开机自启
1.8 安装 kubeadm，kubelet 和 kubectl
2.5 在其他的分支节点执行(k8s-node1 k8s-node2)
1.1.3 创建storageclass的deployment
一 装备三台机器linux(centos)
ip hostname
192.168.49.101 k8s-master
192.168.49.102 k8s-node1
192.168.49.103 k8s-node2
二 准备前置环境并安装kubernetes
1 三台机器都要做如下操作
1.1 关闭防火墙：
systemctl stop firewalld
systemctl disable firewalld1.2 关闭 selinux：
sed -i 's/enforcing/disabled/'
/etc/selinux/config setenforce 01.3 关闭 swap
swapoff -a #临时
sed -ri 's/.*swap.*/#&/' /etc/fstab #永久
free -g #验证，swap 必须为 0；1.4 添加主机名与 IP 对应关系
vi /etc/hosts
192.168.49.101 k8s-master
192.168.49.101 k8s-node1
192.168.49.101 k8s-node21.5 date 查看时间 （可选）
yum install -y
ntpdate ntpdate time.windows.com 同步最新时间1.6 卸载系统之前的 docke 命令自行百度不做说明
1.7 安装 Docker-CE
1. 7.1 装必须的依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm21.7.2 设置 docker repo 的 yum 位置
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo1.7.3 安装 docker，以及 docker-cli
sudo yum install -y docker-ce docker-ce-cli containerd.io1.7.4 配置 docker 加速器(自己去阿里云镜像加速器粘贴 下面是例子 不一定好用)
sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart dock1.7.5 动 docker & 设置 docker 开机自启
systemctl enable docker1.7.6 添加阿里云 yum
cat > /etc/yum.repos.d/kubernetes.repo << EOF [kubernetes] name=Kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=0 repo_gpgcheck=0 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg EOF1.8 安装 kubeadm，kubelet 和 kubectl
yum list|grep kube
yum install -y kubelet-1.19.0 kubeadm-1.19.0 kubectl-1.19.0
systemctl enable kubelet
systemctl start kubele2 部署 k8s-master
2.1 master 机器上执行
kubeadm init --kubernetes-version=v1.19.0 \
--apiserver-advertise-address=192.168.49.101 \ # apiserver-advertise-address 改成你自己的IP
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.1.0.0/16 \
--pod-network-cidr=10.244.0.0/162.2 等待上诉命令执行完成
执行打印的日志
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.49.101:6443 --token 8alqa1.28d3n8pjzxlmex1q --discovery-token-ca-cert-hash sha256:a3883e22dbdbca2ce3c1de98b5e58379e38d3750abfb7d82bd014526b834061e 2.3 master执行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config2.4 在master节点上安装网络

vim kube-flannel.yml
在master上执行
kubectl apply -f kube-flannel.yml
查看执行情况 kubectl get pods --all-namespaces 所有状态为Running
查看主机运行状态 kubectl get nodes 如图:
2.5 在其他的分支节点执行(k8s-node1 k8s-node2)
kubeadm join 192.168.49.101:6443 --token 8alqa1.28d3n8pjzxlmex1q --discovery-token-ca-cert-hash sha256:a3883e22dbdbca2ce3c1de98b5e58379e38d3750abfb7d82bd014526b834061e
分支节点执行上述命令等待所有机器加入master
查看所有机器状态如下为成功
如果到此时 等待时间过久 或者是2.1 kubeadm init..... 失败
重装k8s 再次尝试
卸载k8s的命令
systemctl stop kubelet
systemctl stop etcd
systemctl stop docker
kubeadm reset -f
modprobe -r ipip
lsmod
rm -rf ~/.kube/
rm -rf /etc/kubernetes/
rm -rf /etc/systemd/system/kubelet.service.d
rm -rf /etc/systemd/system/kubelet.service
rm -rf /usr/bin/kube*
rm -rf /etc/cni
rm -rf /opt/cni
rm -rf /var/lib/etcd
rm -rf /var/etcd
yum -y remove kube*
yum clean all
yum -y update
yum makecache多执行几次 保证删除干净 如果master 卸载不了 重启机器再尝试删除
删除成功后 再执行 1.8 -2.5 小结的操作
到此k8s 安装成功 自己可以创建pod service 验证下 百度有
三 安装 kubesphere
1.1 创建StorageClass存储
1.1.1 创建kubesphere-system命名空间
vim ks-namespace.yaml
apiVersion: v1
kind: Namespace
metadata:
name: kubesphere-system
labels:
name: kubesphere-system
kubectl apply -f ks-namespace.yaml
1.1.2 创建rbac授权
vim sc-rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: nfs-client-provisioner
namespace: kubesphere-system
---
apiVersion: rbac.authorization.k8s.io/v1

roleRef:
kind: ClusterRole
name: nfs-client-provisioner-cr
apiGroup: rbac.authorization.k8s.io
kubectl apply -f sc-rbac.yaml
1.1.3 创建storageclass的deployment
vim sc-deployment.yaml
NFS_SERVER 设置为安装nfs服务的服务器ip地址
NFS_PATH 即安装nfs服务的时候创建的挂载目录
volumes中的nfs同样需要配置对应的nfs环境信息
vim sc-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nfs-client-provisioner
namespace: kubesphere-system
spec:
replicas: 1
selector:
matchLabels:
app: nfs-client-provisioner
strategy:
type: Recreate
template:
metadata:
labels:
app: nfs-client-provisioner
spec:
serviceAccountName: nfs-client-provisioner
containers:
- name: nfs-client-provisioner
image: registry.cn-beijing.aliyuncs.com/xngczl/nfs-subdir-external-provisione:v4.0.0
env:
- name: PROVISIONER_NAME
value: nfs-storage-class
- name: NFS_SERVER
value: 192.168.16.40
- name: NFS_PATH
value: /root/data/nfs/storageclass
volumeMounts:
- name: nfs-client-root
mountPath: /persistentvolumes
volumes:
- name: nfs-client-root
nfs:
server: 192.168.16.40
path: /root/data/nfs/storageclass
kubectl apply -f sc-deployment.yaml
1.1.4 创建StorageClass
vim sc-resource.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: nfs-storageclass
provisioner: nfs-storage-class
allowVolumeExpansion: true
reclaimPolicy: Retain
kubectl apply -f sc-resource.yaml
1.1.5 查看StorageClass
[root@master kubersphere]# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
nfs-storageclass nfs-storage-class Retain Immediate true 33s
sc-nexus3 kubernetes.io/no-provisioner Delete WaitForFirstConsumer false 88d
1.1.6 设置默认的StorageClass
kubectl patch storageclass nfs-storageclass -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
再次查看，可以看到此时已经设置好默认的StorageClass了
[root@master kubersphere]# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
nfs-storageclass (default) nfs-storage-class Retain Immediate true 2m6s
sc-nexus3 kubernetes.io/no-provisioner Delete WaitForFirstConsumer false 88d
[root@master kubersphere]#
1.2 部署最小化Kubersphere
1.2.1 下载kubersphere的配控文件
