Kubernetes集群安装
1、集群规划
| 机器名 | IP地址 | 集群角色 | CPU(>=) | 内存(>=) |
|---|---|---|---|---|
| Servera | 172.16.220.10/24 | Master | 2C | 2G |
| Serverb | 172.16.220.20/24 | Worker | 2C | 2G |
| Serverc | 172.16.220.30/24 | Worker | 2C | 2G |
2、必要的准备
- 所有节点都要执行的操作
# 1.关闭防火墙
systemctl stop firewalld
systemctl disable firewalld# 2.同步时间注意：虚拟机不管关机还是挂起，每次重新操作都需要更新时间进行同步。
yum install ntpdate -y
ntpdate time.windows.com# 3.设置主机名字
hostnamectl set-hostname servera
hostnamectl set-hostname serverb
hostnamectl set-hostname serverc# 4.设置hosts
cat >> /etc/hosts << EOF
192.168.192.129 servera
192.168.192.130 serverb
192.168.192.131 serverc
EOF还原所有虚拟机和设置，每个机器必须为2颗CPU，2G内存 必须满足，调整CPU颗数
关闭每台机器的swap分区、设置内核参数和命令行自动补全功能，servera、serverb、serverc都需要操作
#关闭swap分区，编辑/etc/fstab，注释swap分区
$ vim /etc/fstab
#/dev/mapper/centos-swap swap swap defaults 0 0#调整内核参数
$ vim /etc/sysctl.conf
net.bridge.bridge-nf-call-iptables = 1#永久生效，sysctl.conf kernel参数
$ modprobe br_netfilter
$ sysctl -p#sysctl -p这里会报错
[root@serverb ~]# sysctl -p
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
[root@serverb ~]# modprobe br_netfilter
[root@serverb ~]# sysctl -p
net.bridge.bridge-nf-call-iptables = 1
[root@servera ~]# ls /proc/sys/net/bridge
bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-filter-vlan-tagged
bridge-nf-call-ip6tables bridge-nf-filter-pppoe-tagged bridge-nf-pass-vlan-input-dev
[root@servera ~]##安装bash命令行补全工具
$ yum install bash-completion -y
$ reboot #调整环境变量，将一下两行添加到文件最下方
vim /root/.bash_profile
$ /root/.bash_profile
. <(kubeadm completion bash)
. <(kubectl completion bash)#安装所需要的基础软件
$ yum install -y yum-utils device-mapper-persistent-data lvm2#查看docker软件是否存在,如果存在卸载
$ rpm -qa |grep docker
docker-ce-rootless-extras-20.10.17-3.el7.x86_64
docker-scan-plugin-0.17.0-3.el7.x86_64
docker-ce-20.10.17-3.el7.x86_64
docker-ce-cli-20.10.17-3.el7.x86_64$ rpm -e --nodeps xxx
rpm -e --nodeps docker-ce-rootless-extras-20.10.17-3.el7.x86_64
rpm -e --nodeps docker-scan-plugin-0.17.0-3.el7.x86_64

rpm -e --nodeps docker-ce-cli-20.10.17-3.el7.x86_643、上传离线软件到servera,serverb,serverc
- 使用百度网盘下载集群安装的离线软件包
#下载地址
链接: https://pan.baidu.com/s/1TD6G2JKUoZsJ18NBLeQMRA 密码: c3cr
- 使用文件上传工具将文件上传至servera、serverb、serverc的/tmp目录下，每台机器都要上传，都上传至/tmp下
- 解压缩文件，不需要解压缩images-k8s.tar文件
# win中复制命令
scp -r D:\01-R-training\07-kuberbets-20210316\k8s-offline-software\* root@172.16.220.10:/tmpscp -r D:\01-R-training\07-kuberbets-20210316\k8s-offline-software\* root@172.16.220.20:/tmpscp -r D:\01-R-training\07-kuberbets-20210316\k8s-offline-software\* root@172.16.220.30:/tmp$ cd /tmp
$ tar xvf rpm-k8s.tar.bz2
$ tar xvf rpm-docker.tar.bz2
4、安装docker-ce软件，三台机器都需要安装
- 安装docker-ce (servera,serverb,serverc), 必须使用**yum localinstall **命令安装，如果直接下载互联网软件docker版本将是20.10.
$ yum localinstall -y /tmp/rpm-docker/*.rpm
- 启动docker服务 (servera,serverb,serverc)
$ systemctl enable --now docker # 等价于 先start 再 enable
5、安装K8s软件
- 安装k8s软件 (servera,serverb,serverc)
$ yum localinstall -y /tmp/rpm-k8s/*.rpm
- 启动kubelet服务 (servera,serverb,serverc)
$ systemctl enable --now docker kubelet# 等价于 先start 再 enable
6、加载k8s所需要的镜像
- 加载docker 镜像 (servera,serverb,serverc)
$ docker load -i /tmp/image-k8s.tar#使用docker images命令校验
$ docker images
7、设置docker daemon参数
- 创建docker daemon文件 (servera,serverb,serverc)
$ cat > /etc/docker/daemon.json <<EOF
{"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"storage-driver": "overlay2","storage-opts": ["overlay2.override_kernel_check=true"]
}
EOF
- 重新加载systemd文件及启动服务 (servera,serverb,serverc)
$ systemctl daemon-reload
$ systemctl restart docker
8、创建kubeadm-config.yaml文件安装集群
- 创建kubeadm-config.yaml文件(servera)
$ cat > /tmp/kubeadm-config.yaml <<EOF

- kubeadm初始化集群 (servera)

# 删除老service
1）执行重置命令：kubeadm reset -f2）删除所有相关数据
rm -rf /etc/cni /etc/kubernetes /var/lib/dockershim /var/lib/etcd /var/lib/kubelet /var/run/kubernetes ~/.kube/*3）刷新所有防火墙(iptables)规则

iptables -t mangle -F && iptables -t mangle -X4）重启Docker服务
systemctl restart docker
kubeadm reset
systemctl disable kubelet
rm -rf /etc/systemd/system/kubelet.service ## 生成的命令行内容复制下来
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/.kubesudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/configsudo chown $(id -u):$(id -g) $HOME/.kube/configYou 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 192.168.192.129:6443 --token 8ow2fk.7qfwswis5od7c389 \--discovery-token-ca-cert-hash sha256:7d5b404aa17ca7aeef938ee4ccc42bde7386241d9d0c2e5a6e74c3fe77848098
[root@servera tmp]# - 配置api链接配置文件（kubectl)
$ mkdir -p $HOME/.kube
$ cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
$ chown $(id -u):$(id -g) $HOME/.kube/config
10、部署k8s网络
- 创建flannel网络配置文件
$ vim kube-flannel.yml

- 执行配置文件（servera）
$ kubectl apply -f kube-flannel.yml 指定目录：kubectl apply -f /tmp/kube-flannel.yml - 查看是否有flannel pod其是否启动(servera)
#查看时有部分的pod处于在pening状态
$ kubectl get pods -n kube-system# kube-system是系统默认的namespace
[root@servera ~]# kubectl get pods -n kube-system

[root@servera ~]# 11、其他节点接入集群
- 加入集群(serverc、serverd)
# 在servera 执行kubeadm 初始化命令，输出的
$ kubeadm join 172.16.220.10:6443 --token tss6it.kn7j83kseixt0v8u --discovery-token-ca-cert-hash sha256:707e3776b1d4377a331523a8b51b062d3cb86305b05083be8f3be72017d58059
- 集群扩容，添加节点
$ kubeadm token create --print-join-command
#我的输出如下
[root@servera ~]# kubeadm token create --print-join-command
kubeadm join 172.16.220.10:6443 --token 9q7jq5.em3ozm547y3znjin --discovery-token-ca-cert-hash sha256:f268772578ce0e1ab65639fe6d03f65a6a0667bfbc0701c6d4245af13c510b73 12、查看集群阶段是都正常
- 获取集群阶段信息(servera)
$ kubectl get nodes
[root@servera ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
servera.training.example.com Ready master 20m v1.16.12
serverb.training.example.com NotReady <none> 19s v1.16.12
serverc.training.example.com NotReady <none> 18s v1.16.12#几分钟之后
[root@servera ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
servera.training.example.com Ready master 20m v1.16.12
serverb.training.example.com Ready <none> 35s v1.16.12
serverc.training.example.com Ready <none> 34s v1.16.12
13、集群安装后测试
#调整环境变量，将一下两行添加到文件最下方,三个机器都要执行
$ vim /root/.bash_profile
. <(kubeadm completion bash)
. <(kubectl completion bash)$ source /root/.bash_profile#启动一个app（任意）
#-l：label=“”
$ kubectl create namespace training
$ kubectl run first-app -l app=first-app --image=nginx:1.16 -n training
$ kubectl get pods -n training
$ kubectl describe pods first-app-xxxxxx-yyyyy -n trianing13.1、slave节点不能执行集群kubectl 命令
- 13.1.1将master中的/etc/kubernetes/admin.conf 配置文件复制到slave节点
# 1、先复制到从节点
[root@servera ~]# scp -r /etc/kubernetes/admin.conf root@serverc:/etc/kubernetes/admin.conf
admin.conf 100% 5453 1.8MB/s 00:00
[root@servera ~]# - 13.1.2slave节点中配置环境变量
#2、配置环境变量
[root@serverc kubernetes]# echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile
[root@serverc kubernetes]# source ~/.bash_profile #从节点执行 kubectl get nodes，可以查看该内容代表成功
[root@serverc kubernetes]# kubectl get nodes
