在vmware中安装,创建三台centos服务器
主机 | ip | 配置 |
---|---|---|
master | 192.168.42.188 | 4核,6g内存,40g硬盘 |
node1 | 192.168.42.189 | 2核,2g内存,20g硬盘 |
node2 | 192.168.42.190 | 2核,2g内存,20g硬盘 |
vim /etc/hosts
192.168.42.188 master
192.168.42.189 node1
192.168.42.190 node2
先生成密钥,再复制到所有节点
ssh-keygen
ssh-copy-id master
ssh-copy-id node1
ssh-copy-id node2
#测试连接
ssh node1
kubelet要求必须禁用交换分区,所以kubeadm初始化时回检测swap是否关闭,如果没有关闭会报错,如果不想关闭安装时命令行可以指定
-ignore-preflight-errors=Swap,关闭Swap分区在所有节点上执行如下命令:
#临时关闭
swapoff -a
#永久关闭
echo vm.swappiness = 0 >> /etc/sysctl.conf
sysctl -p
#我在虚拟机中重启后状态仍然是开启,不知道是什么原因,没有影响流程,就没有继续查下去
systemctl disable firewalld
systemctl stop firewalld
modprobe br_netfilter
echo "modprobe br_netfilter" >> /etc/profile
tee /etc/sysctl.d/k8s.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
#重新加载配置
sysctl -p /etc/sysctl.d/k8s.conf
#安装日期插件
yum install -y ntp ntpdate
ntpdate cn.pool.ntp.org
systemctl start ntpd
systemctl enable ntpd
这里配置k8s的aliyun源
vim /etc/yum.repos.d/kubernetes.repo
#将以下内容复制进去
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=0
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate
配置阿里云的yum仓库地址,默认国外的下载速度比较慢
yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
yum-config-manager \
--add-repo \
https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce-20.10.9-3.el7 docker-ce-cli-20.10.9-3.el7 docker-compose-plugin containerd.io
#启动docker
systemctl start docker
#设置开机自启
systemctl enable docker
#验证安装
docker -v
配置阿里云镜像加速器
cat > /etc/docker/daemon.json << EOF
{
"registry-mirrors": ["https://p59n3y39.mirror.aliyuncs.com"]
}
> EOF
重新加载并重启
sudo systemctl daemon-reload
sudo systemctl restart docke
kubeadm:用来初始化k8s集群的指令。
kubelet:在集群的每个节点上用来启动 Pod 和容器等。
kubectl:用来与k8s集群通信的命令行工具,查看、创建、更新和删除各种资源。
yum install -y kubelet-1.23.17 kubeadm-1.23.17 kubectl-1.23.17
所有节点设置开机自启
systemctl enable kubelet
echo "192.168.42.188 cluster-endpoint" >> /etc/hosts
kubeadm init \
--apiserver-advertise-address=192.168.199.128 \
--control-plane-endpoint=cluster-endpoint \
--image-repository registry.cn-hangzhou.aliyuncs.com/google_containers \
--kubernetes-version v1.23.17 \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=172.20.0.0/16
成功界面
Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
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 cluster-endpoint:6443 --token e8enii.joiejbe3xoj6v9mt \
--discovery-token-ca-cert-hash sha256:5756518626710f38bc3b7d4a405990c6274b513628467df94d1aa0a5c5b6f196
kubeadm join cluster-endpoint:6443 --token e8enii.joiejbe3xoj6v9mt \
--discovery-token-ca-cert-hash sha256:5756518626710f38bc3b7d4a405990c6274b513628467df94d1aa0a5c5b6f196
查看token列表,可观察到每个token的剩余有效时间
TOKEN TTL EXPIRES USAGES DESCRIPTION EXTRA GROUPS
p2hjar.gvqyz2ip3nqyac2c 23h 2024-09-01T08:56:31Z authentication,signing system:bootstrappers:kubeadm:default-node-token
默认token有效期为24小时,过期之后token失效,可重新生成token

然后停止jenkins容器,记得是停止!
查找jenkins服务
docker ps -a|grep jenkins
docker stop
执行docker cp命令,将war拉取到jenkins容器内
docker cp jenkins.war :/usr/share/jenkins/jenkins.war
再启动容器
docker start
