centos7安装kubernetes v1.16.0

一、资源

系统	ip	主机名	内核	说明
centos7	192.168.179.135	master	3.10.0-1062.el7.x86_64	k8s主节点
centos7	192.168.179.136	node1	3.10.0-1062.el7.x86_64	k8s从节点

二、系统配置

2.1 修改主机名（所有节点）

vi /etc/hosts
----------------------------------------------------------------------------------------------------------------------------------
192.168.179.135 master
192.168.179.136 node1
---------------------------------------------------------------------------------------------------------------------------------

vi /etc/hostname
---------------------------------------------------------------------------------------------------------------------------------
// 主节点配置master 从节点配置node1
master
---------------------------------------------------------------------------------------------------------------------------------

vi /etc/sysconfig/network
---------------------------------------------------------------------------------------------------------------------------------
// 主节点配置master 从节点配置node1
HOSTNAME=master
---------------------------------------------------------------------------------------------------------------------------------

修改完主机名需要重启一下机器才会生效

2.2 k8s环境准备(所有节点)

安装k8s的机器需要2核和2g内存以上

//关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
//关闭selinux
// 临时禁用selinux
setenforce 0
// 永久关闭 修改/etc/sysconfig/selinux文件设置
sed -i 's/SELINUX=permissive/SELINUX=disabled/' /etc/sysconfig/selinux
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
//禁用交换分区
swapoff -a
# 永久禁用，打开/etc/fstab注释掉swap那一行。
sed -i 's/.*swap.*/#&/' /etc/fstab
// 修改内核参数
cat <<EOF >  /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
//使配置生效
sysctl --system

2.3 安装docker （所有节点）

// 安装docker所需的工具
yum install -y yum-utils device-mapper-persistent-data lvm2
// 配置阿里云的docker源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
// 指定安装这个版本的docker-ce
yum install -y docker-ce-18.09.9-3.el7
// 启动docker
systemctl enable docker && systemctl start docker

2.4 安装kubeadm、kubelet、kubectl

由于官方k8s源在google，国内无法访问，这里使用阿里云yum源

// 执行配置k8s阿里云源
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

// 安装kubeadm、kubectl、kubelet
yum install -y kubectl-1.16.0-0 kubeadm-1.16.0-0 kubelet-1.16.0-0

// 启动kubelet服务
systemctl enable kubelet && systemctl start kubelet

三、安装k8s

3.1 初始化k8s（master节点）

以下这个命令开始安装k8s需要用到的docker镜像，因为无法访问到国外网站，所以这条命令使用的是国内的阿里云的源(registry.aliyuncs.com/google_containers)。另一个非常重要的是：这里的–apiserver-advertise-address使用的是master和node间能互相ping通的ip，我这里是192.168.179.135。 这条命令执行时会卡在[preflight] You can also perform this action in beforehand using ''kubeadm config images pull，大概需要2分钟，请耐心等待。

// 下载管理节点中用到的6个docker镜像，你可以使用docker images查看到
// 这里需要大概两分钟等待，会卡在[preflight] You can also perform this action in beforehand using ''kubeadm config images pull
kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.16.0 --apiserver-advertise-address 192.168.179.135 --pod-network-cidr=10.244.0.0/16 --token-ttl 0

上面安装完后，会提示你输入如下命令，复制粘贴过来，执行即可

// 上面安装完成后，k8s会提示你输入如下命令，执行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

init执行成功后需要保存上图 kubeadm join 数据，如果忘记保存可以通过如下命令获取

kubeadm token create --print-join-command 

查看节点状态，NotReady状态是因为还没有安装网络flanneld，暂时先不用管

[root@master resources]# kubectl get cs
NAME                 STATUS    MESSAGE             ERROR
scheduler            Healthy   ok
controller-manager   Healthy   ok
etcd-0               Healthy   {"health":"true"}

[root@master k8s]# kubectl get node
NAME     STATUS     ROLES    AGE     VERSION
master   NotReady   master   7m22s   v1.18.1

集群初始化如果遇到问题，可以使用下面的命令进行清理：

kubeadm reset

3.2 从节点加入集群（所有从节点）

如果忘记加入集群的命令可以登录master节点，使用kubeadm token create --print-join-command 来获取

// 加入集群，如果这里不知道加入集群的命令，可以登录master节点，使用kubeadm token create --print-join-command 来获取 
kubeadm join 192.168.179.135:6443 --token frqj64.dcrc5uu3skgb1fyc \
    --discovery-token-ca-cert-hash sha256:715916dfae4d5118db1004ccb289826fb552cfed215862dbb13e6e9fc7add8b3

加入成功后，可以在master节点上使用kubectl get nodes命令查看到加入的节点。

3.3 安装flannel（master节点）

使用wget命令，地址为：(https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml)，这个地址国内访问不了，所以我把内容复制下来，为了避免前面文章过长，我把它粘贴到文章末尾第八个步骤附录了。这个yml配置文件中配置了一个国内无法访问的地址(quay.io)，我已经将其改为国内可以访问的地址(quay-mirror.qiniu.com)。我们新建一个kube-flannel.yml文件，复制粘贴该内容即可。

[root@master ~]# kubectl apply -f kube-flannel.yml
podsecuritypolicy.policy/psp.flannel.unprivileged created
clusterrole.rbac.authorization.k8s.io/flannel created
clusterrolebinding.rbac.authorization.k8s.io/flannel created
serviceaccount/flannel created
configmap/kube-flannel-cfg created
daemonset.apps/kube-flannel-ds-amd64 created
daemonset.apps/kube-flannel-ds-arm64 created
daemonset.apps/kube-flannel-ds-arm created
daemonset.apps/kube-flannel-ds-ppc64le created
daemonset.apps/kube-flannel-ds-s390x created
// 状态已经变成Ready
[root@master ~]# kubectl get nodes
NAME     STATUS   ROLES    AGE   VERSION
master   Ready    master   17h   v1.16.0
node1    Ready    <none>   17h   v1.16.0
//确保所有status都是running
[root@master ~]# kubectl get pod -n kube-system
NAME                             READY   STATUS    RESTARTS   AGE
coredns-58cc8c89f4-vkjdv         1/1     Running   0          17h
coredns-58cc8c89f4-wrfb7         1/1     Running   0          17h

kube-proxy-rwnm6                 1/1     Running   0          17h
kube-scheduler-master            1/1     Running   0          17h

四、安装k8s UI界面dashboard（不推荐），推荐kuboard安装

4.1 下载dashboard配置文件

wget https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended.yaml，这个地址国内访问不了，所以我把内容复制下来，同样放到文章结尾附录中。

4.2 修改配置

[root@master ~]# vi recommended.yaml
//修改如下配置 nodePort是对外暴露的端口

初始化dashboard配置

[root@master ~]# kubectl apply -f recommended.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created


[root@master ~]#  kubectl get pods -n kubernetes-dashboard
NAME                                        READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-c79c65bb7-ms7g6   1/1     Running   0          2s
kubernetes-dashboard-8598b578f6-24wlm       1/1     Running   0          3s

如果需要修改配置文件重新初始化dashboard配置，执行如下命令：

[root@master ~]# kubectl delete -f recommended.yaml
namespace "kubernetes-dashboard" deleted
serviceaccount "kubernetes-dashboard" deleted
service "kubernetes-dashboard" deleted
secret "kubernetes-dashboard-certs" deleted
secret "kubernetes-dashboard-csrf" deleted
secret "kubernetes-dashboard-key-holder" deleted
configmap "kubernetes-dashboard-settings" deleted
role.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
clusterrole.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
rolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
clusterrolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
deployment.apps "kubernetes-dashboard" deleted
service "dashboard-metrics-scraper" deleted
deployment.apps "dashboard-metrics-scraper" deleted

修改完配置之后重新执行：kubectl apply -f recommended.yaml

4.3 火狐浏览器访问

由于证书问题，只能firefox浏览器才能打开，如果想让所有浏览器访问需要修改证书，我这里就不做修改了
使用火狐访问https://192.168.179.135:32443/出现

可以看到出现下图画面，需要我们输入一个kubeconfig文件或者一个token。事实上在安装dashboard时，也为我们默认创建好了一个serviceaccount，为kubernetes-dashboard，并为其生成好了token，我们可以通过如下指令获取token：

[root@master ~]#  kubectl describe secret -n kubernetes-dashboard $(kubectl get secret -n kubernetes-dashboard |grep  kubernetes-dashboard-token | awk '{print $1}') |grep token | awk '{print $2}'  

复制上面内容粘贴

登录

通过该token登入集群以后，发现很多namespace包括一些其他的资源都没有足够的权限查看。这是因为默认我们使用的这个帐户只有有限的权限。我们可以通过授予cluster-admin权限来解决这个问题

[root@master ~]#  vi recommended.yaml 
-----------------------------------------------------------------------------
//修改为如下配置
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: kubernetes-dashboard
    namespace: kubernetes-dashboard
-----------------------------------------------------------------------------

重新初始化dashboard

[root@master ~]# kubectl delete -f recommended.yaml
namespace "kubernetes-dashboard" deleted
serviceaccount "kubernetes-dashboard" deleted
service "kubernetes-dashboard" deleted
secret "kubernetes-dashboard-certs" deleted
secret "kubernetes-dashboard-csrf" deleted
secret "kubernetes-dashboard-key-holder" deleted
configmap "kubernetes-dashboard-settings" deleted
role.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
clusterrole.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
rolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
clusterrolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
deployment.apps "kubernetes-dashboard" deleted
service "dashboard-metrics-scraper" deleted
deployment.apps "dashboard-metrics-scraper" deleted

// 初始化
[root@master ~]# kubectl apply -f recommended.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created

//重新获取token
[root@master ~]#  kubectl describe secret -n kubernetes-dashboard $(kubectl get secret -n kubernetes-dashboard |grep  kubernetes-dashboard-token | awk '{print $1}') |grep token | awk '{print $2}'  

使用新token再次登录就会看到如下信息

至此 安装完成
