服务器免密码登录

在各服务器执行如下命令。

ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys 

将binghe102和binghe103服务器上的id_rsa.pub文件复制到binghe101服务器。

[root@binghe102 ~]# scp .ssh/id_rsa.pub binghe101:/root/.ssh/102
[root@binghe103 ~]# scp .ssh/id_rsa.pub binghe101:/root/.ssh/103

在binghe101服务器上执行如下命令。

cat ~/.ssh/102 >> ~/.ssh/authorized_keys
cat ~/.ssh/103 >> ~/.ssh/authorized_keys

然后将authorized_keys文件分别复制到binghe102、binghe103服务器。

[root@binghe101 ~]# scp .ssh/authorized_keys binghe102:/root/.ssh/authorized_keys
[root@binghe101 ~]# scp .ssh/authorized_keys binghe103:/root/.ssh/authorized_keys

删除binghe101节点上~/.ssh下的102和103文件。

rm ~/.ssh/102
rm ~/.ssh/103

安装JDK

需要在每台服务器上安装JDK环境。到Oracle官方下载JDK，我这里下的JDK版本为1.8.0_202，下载后解压并配置系统环境变量。

tar -zxvf jdk1.8.0_212.tar.gz
mv jdk1.8.0_212 /usr/local

接下来，配置系统环境变量。

vim /etc/profile

配置项内容如下所示。

JAVA_HOME=/usr/local/jdk1.8.0_212
CLASS_PATH=.:$JAVA_HOME/lib
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASS_PATH PATH

接下来执行如下命令使系统环境变量生效。

source /etc/profile

安装Maven

到Apache官方下载Maven，我这里下载的Maven版本为3.6.3。下载后直接解压并配置系统环境变量。

tar -zxvf apache-maven-3.6.3-bin.tar.gz
mv apache-maven-3.6.3-bin /usr/local

接下来，就是配置系统环境变量。

vim /etc/profile

配置项内容如下所示。

JAVA_HOME=/usr/local/jdk1.8.0_212
MAVEN_HOME=/usr/local/apache-maven-3.6.3-bin
CLASS_PATH=.:$JAVA_HOME/lib
PATH=$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASS_PATH MAVEN_HOME PATH

接下来执行如下命令使系统环境变量生效。

source /etc/profile

接下来，修改Maven的配置文件，如下所示。

<localRepository>/home/repository</localRepository>

将Maven下载的Jar包存储到/home/repository目录下。

安装Docker环境

本文档基于Docker 19.03.8 版本搭建Docker环境。

在所有服务器上创建install_docker.sh脚本，脚本内容如下所示。

export REGISTRY_MIRROR=https://registry.cn-hangzhou.aliyuncs.com
dnf install yum*
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
dnf install https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.13-3.1.el7.x86_64.rpm
yum install -y docker-ce-19.03.8 docker-ce-cli-19.03.8
systemctl enable docker.service
systemctl start docker.service
docker version

在每台服务器上为install_docker.sh脚本赋予可执行权限，并执行脚本即可。

安装docker-compose

注意：在每台服务器上安装docker-compose

1.下载docker-compose文件

curl -L https://github.com/docker/compose/releases/download/1.25.5/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose 

2.为docker-compose文件赋予可执行权限

chmod a+x /usr/local/bin/docker-compose

3.查看docker-compose版本

[root@binghe ~]# docker-compose version
docker-compose version 1.25.5, build 8a1c60f6
docker-py version: 4.1.0
CPython version: 3.7.5
OpenSSL version: OpenSSL 1.1.0l  10 Sep 2019

安装K8S集群环境

本文档基于K8S 1.8.12版本来搭建K8S集群

安装K8S基础环境

在所有服务器上创建install_k8s.sh脚本文件，脚本文件的内容如下所示。

docker version

在每台服务器上为install_k8s.sh脚本赋予可执行权限，并执行脚本即可。

初始化Master节点

只在binghe101服务器上执行的操作。

1.初始化Master节点的网络环境

注意：下面的命令需要在命令行手动执行。

# 只在 master 节点执行
# export 命令只在当前 shell 会话中有效，开启新的 shell 窗口后，如果要继续安装过程，请重新执行此处的 export 命令
export MASTER_IP=192.168.175.101
# 替换 k8s.master 为 您想要的 dnsName
export APISERVER_NAME=k8s.master
# Kubernetes 容器组所在的网段，该网段安装完成后，由 kubernetes 创建，事先并不存在于物理网络中
export POD_SUBNET=172.18.0.1/16
echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts

2.初始化Master节点

在binghe101服务器上创建init_master.sh脚本文件，文件内容如下所示。

#!/bin/bash
# 脚本出错时终止执行
set -e

if [ ${#POD_SUBNET} -eq 0 ] || [ ${#APISERVER_NAME} -eq 0 ]; then
  echo -e "\\033[31;1m请确保您已经设置了环境变量 POD_SUBNET 和 APISERVER_NAME \\033[0m"
  echo 当前POD_SUBNET=$POD_SUBNET
  echo 当前APISERVER_NAME=$APISERVER_NAME
  exit 1
fi


# 查看完整配置选项 https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta2

EOF

# kubeadm init
# 根据服务器网速的情况，您需要等候 3 - 10 分钟
kubeadm init --config=kubeadm-config.yaml --upload-certs

# 配置 kubectl
rm -rf /root/.kube/
mkdir /root/.kube/
cp -i /etc/kubernetes/admin.conf /root/.kube/config

# 安装 calico 网络插件
# 参考文档 https://docs.projectcalico.org/v3.13/getting-started/kubernetes/self-managed-onprem/onpremises
echo "安装calico-3.13.1"
rm -f calico-3.13.1.yaml
wget https://kuboard.cn/install-script/calico/calico-3.13.1.yaml
kubectl apply -f calico-3.13.1.yaml

赋予init_master.sh脚本文件可执行权限并执行脚本。

3.查看Master节点的初始化结果

（1）确保所有容器组处于Running状态

# 执行如下命令，等待 3-10 分钟，直到所有的容器组处于 Running 状态
watch kubectl get pod -n kube-system -o wide

具体执行如下所示。

[root@binghe101 ~]# watch kubectl get pod -n kube-system -o wide
Every 2.0s: kubectl get pod -n kube-system -o wide                                                                                                                          binghe101: Sun May 10 11:01:32 2020

（2） 查看 Master 节点初始化结果

kubectl get nodes -o wide

具体执行如下所示。

[root@binghe101 ~]# kubectl get nodes -o wide
NAME        STATUS   ROLES    AGE     VERSION   INTERNAL-IP       EXTERNAL-IP   OS-IMAGE                KERNEL-VERSION         CONTAINER-RUNTIME

初始化Worker节点

1.获取join命令参数

在Master节点（binghe101服务器）上执行如下命令获取join命令参数。

kubeadm token create --print-join-command

具体执行如下所示。

[root@binghe101 ~]# kubeadm token create --print-join-command
W0510 11:04:34.828126   56132 configset.go:202] WARNING: kubeadm cannot validate component configs for API groups [kubelet.config.k8s.io kubeproxy.config.k8s.io]
kubeadm join k8s.master:6443 --token 8nblts.62xytoqufwsqzko2     --discovery-token-ca-cert-hash sha256:1717cc3e34f6a56b642b5751796530e367aa73f4113d09994ac3455e33047c0d 

其中，有如下一行输出。

kubeadm join k8s.master:6443 --token 8nblts.62xytoqufwsqzko2     --discovery-token-ca-cert-hash sha256:1717cc3e34f6a56b642b5751796530e367aa73f4113d09994ac3455e33047c0d 

这行代码就是获取到的join命令。

注意：join命令中的token的有效时间为 2 个小时，2小时内，可以使用此 token 初始化任意数量的 worker 节点。

2.初始化Worker节点

针对所有的 worker 节点执行，在这里，就是在binghe102服务器和binghe103服务器上执行。

在命令分别手动执行如下命令。

# 只在 worker 节点执行
# 192.168.175.101 为 master 节点的内网 IP
export MASTER_IP=192.168.175.101
# 替换 k8s.master 为初始化 master 节点时所使用的 APISERVER_NAME
export APISERVER_NAME=k8s.master
echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts

# 替换为 master 节点上 kubeadm token create 命令输出的join
kubeadm join k8s.master:6443 --token 8nblts.62xytoqufwsqzko2     --discovery-token-ca-cert-hash sha256:1717cc3e34f6a56b642b5751796530e367aa73f4113d09994ac3455e33047c0d 

具体执行如下所示。

[root@binghe102 ~]# export MASTER_IP=192.168.175.101
[root@binghe102 ~]# export APISERVER_NAME=k8s.master
[root@binghe102 ~]# echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts
[root@binghe102 ~]# kubeadm join k8s.master:6443 --token 8nblts.62xytoqufwsqzko2     --discovery-token-ca-cert-hash sha256:1717cc3e34f6a56b642b5751796530e367aa73f4113d09994ac3455e33047c0d 
W0510 11:08:27.709263   42795 join.go:346] [preflight] WARNING: JoinControlPane.controlPlane settings will be ignored when control-plane flag is not set.

This node has joined the cluster:
* Certificate signing request was sent to apiserver and a response was received.
* The Kubelet was informed of the new secure connection details.

Run 'kubectl get nodes' on the control-plane to see this node join the cluster.

根据输出结果可以看出，Worker节点加入了K8S集群。

注意：kubeadm join…就是master 节点上 kubeadm token create 命令输出的join。

3.查看初始化结果

在Master节点（binghe101服务器）执行如下命令查看初始化结果。

kubectl get nodes -o wide

具体执行如下所示。

[root@binghe101 ~]# kubectl get nodes
NAME        STATUS   ROLES    AGE     VERSION
binghe101   Ready    master   20m     v1.18.2
binghe102   Ready    <none>   2m46s   v1.18.2
binghe103   Ready    <none>   2m46s   v1.18.2

注意：kubectl get nodes命令后面加上-o wide参数可以输出更多的信息。

重启K8S集群引起的问题

1.Worker节点故障不能启动

Master 节点的 IP 地址发生变化，导致 worker 节点不能启动。需要重新安装K8S集群，并确保所有节点都有固定的内网 IP 地址。

2.Pod崩溃或不能正常访问

重启服务器后使用如下命令查看Pod的运行状态。

kubectl get pods --all-namespaces

发现很多 Pod 不在 Running 状态，此时，需要使用如下命令删除运行不正常的Pod。

kubectl delete pod <pod-name> -n <pod-namespece>

注意：如果Pod 是使用 Deployment、StatefulSet 等控制器创建的，K8S 将创建新的 Pod 作为替代，重新启动的 Pod 通常能够正常工作。

K8S安装ingress-nginx

注意：在Master节点（binghe101服务器上执行）

1.创建ingress-nginx命名空间

创建ingress-nginx-namespace.yaml文件，文件内容如下所示。

apiVersion: v1
kind: Namespace
metadata:
  name: ingress-nginx
  labels:
    name: ingress-nginx

执行如下命令创建ingress-nginx命名空间。

kubectl apply -f ingress-nginx-namespace.yaml

2.安装ingress controller

创建ingress-nginx-mandatory.yaml文件，文件内容如下所示。

apiVersion: v1
kind: Namespace
metadata:
  name: ingress-nginx
