一、环境配置

配置步骤一：关闭防火墙、selinux和swap

systemctl stop firewalld && systemctl disable firewalld
setenforce 0
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
swapoff -a
sed -i 's/.*swap.*/#&/' /etc/fstab

配置步骤二：配置内核参数，将桥接的IPv4流量传递到iptables的链

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

配置步骤三：配置国内yum源

mkdir /etc/yum.repos.d/bak && mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo
yum clean all && yum makecache

配置步骤四：国内Kubernetes源

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

配置步骤五：docker 源

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

[配置主机名]
hostnamectl set-hostname master
[配置映射]
cat <<EOF >>/etc/hosts
10.0.0.117 thinxz-master
10.0.0.113 thinxz-node1
EOF

二、安装软件

安装步骤一：安装DOCKER

：yum install -y docker-ce-18.06.1.ce-3.el7
：systemctl enable docker && systemctl start docker
：docker version
Docker version 18.06.1-ce, build e68fc7a

安装步骤二：安装 kubeadm、kubelet、kubectl

：yum install -y kubelet kubeadm kubectl
：systemctl enable kubelet

三、配置 Master

Kubernetes集群初始化

kubeadm init --kubernetes-version=1.15.0 \
--apiserver-advertise-address10.0.0.117 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.1.0.0/16 \
--pod-network-cidr=10.244.0.0/16
// kubeadm reset # 重置, 重新安装
// kubeadm init --kubernetes-version=1.15.0 --apiserver-advertise-address=10.0.0.117  --image-repository registry.aliyuncs.com/google_containers --service-cidr=10.1.0.0/16  --pod-network-cidr=10.244.0.0/16
// --apiserver-advertise-address=10.0.0.117 , master主机IP
// –image-repository 指定阿里云镜像仓库地址, 否则默认k8s.grc.io下载
// 集群初始化成功后返回语句, 用于在Node节点加入集群 [记录]
kubeadm join 10.10.10.101:6443 --token 49u7qy.b2qy8sg1c9v47fyb \

配置kubectl工具

mkdir -p /root/.kube
cp /etc/kubernetes/admin.conf /root/.kube/config
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl get nodes
kubectl get cs

五、检测集群状态

[master]

kubectl get nodes

NAME     STATUS   ROLES    AGE     VERSION

master   Ready    master   26m     v1.14.2

node1    Ready    <none>   3m10s   v1.14.2

node2    Ready    <none>   3m      v1.14.2

[创建Pod以验证集群是否正常]

kubectl create deployment nginx --image=nginx
kubectl expose deployment nginx --port=80 --type=NodePort
kubectl get pod,svc

部署Dashboard

// https://blog.csdn.net/qq_22917163/article/details/84527420

[master]

wget https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

[]

sed -i 's/k8s.gcr.io/loveone/g' kubernetes-dashboard.yaml

sed -i '/targetPort:/a\ \ \ \ \ \ nodePort: 30001\n\ \ type: NodePort' kubernetes-dashboard.yaml

[部署]

kubectl create -f kubernetes-dashboard.yaml

[检测]

kubectl get deployment kubernetes-dashboard -n kube-system

kubectl get pods -n kube-system -o wide

kubectl get services -n kube-system

netstat -ntlp|grep 30001

[查看令牌]

kubectl create serviceaccount  dashboard-admin -n kube-system
kubectl create clusterrolebinding  dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
kubectl describe secrets -n kube-system $(kubectl -n kube-system get secret | awk '/dashboard-admin/{print $1}')
