node节点配置与上述配置除IP外其余相同# 重启网络

[rootmaster1 ~]# service network restart3关闭selinux

临时关闭

[rootmaster ~]# setenforce 0# 永久关闭 [rootmaster ~]# vi /etc/selinux/config

将SELINUX设置为disabled

SELINUXdisabled# 此参数修改完成后需要重启服务器才能生效

检查修改状态

[rootmaster ~]# getenforce 显示为Disabled则说明修改成功4配置主机hosts文件

修改服务器的/etc/hosts文件增加如下两行

echo 172.16.32.144 master 172.16.32.145 node /etc/hosts# 修改后显示为 [rootmaster ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.16.32.144 master 172.16.32.145 node5配置服务器之间免密登录 [rootmaster ~]# ssh-keygen #一路回车无需输入密码 [rootmaster ~]# ssh-copy-id master # 复制ssh信息到master节点 [rootmaster ~]# ssh-copy-id node # 复制ssh信息到node节点6关闭交换分区swap提升性能

临时关闭

[rootmaster ~]# swapoff -a

永久关闭

[rootmaster ~]# vi /etc/fstab

/dev/mapper/centos-swap swap swap defaults 0 0

关闭后需要重启服务器否则在初始化k8s时候会报错7修改内核参数

加载模块

[rootmaster~]# modprobe br_netfilter

修改内核参数创建docker.conf文件并写入内核参数

[rootmaster ~]# cat /etc/sysctl.d/docker.conf EOF net.bridge.bridge-nf-call-ip6tables 1 net.bridge.bridge-nf-call-iptables 1 net.ipv4.ip_forward 1 EOF

使参数生效

[rootmaster]# sysctl -p /etc/sysctl.d/docker.conf8关闭firewalld防火墙 [rootmaster]# systemctl stop firewalld systemctl disable firewalld

或 [rootmaster ~]# systemctl disable firewalld –now9配置阿里云repo源

a.yum源修改

默认yum源无法使用需要更换成国内yum源演示为阿里云yum源# 备份基础repo源

[rootmaster ~]# mkdir /root/repo.bak [rootmaster ~]# cd /etc/yum.repos.d/ [rootmaster ~]# mv * /root/repo.bak/

把CentOS-Base.repo文件上传到各个主机的/etc/yum.repos.d/目录下具体内容参考下述CentOS-Base.repo文件内容

安装rzsz

[rootmaster ~]# yum clean all [rootmaster ~]# yum makecache [rootmaster ~]# yum -y install lrzsz openssh-clientsc.添加docker源

配置国内阿里云docker的repo源

[rootmaster1 ~]# yum install yum-utils -y [rootmaster1 ~]# yum-config-manager –add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo10配置安装k8s组件需要的阿里云repo源 [rootmaster ~]# vi /etc/yum.repos.d/kubernetes.repo [kubernetes] nameKubernetes baseurlhttps://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ enabled1 gpgcheck011配置时间同步

安装ntp服务

[rootmaster ~]# yum -y install ntp ntpdate

同步时间若存在本地时间服务器可将cn.pool.ntp.org换成时间服务器IP

[rootmaster ~]# ntpdate cn.pool.ntp.org

编写计划任务

[rootmaster ~]# crontab -e 输入

*/1 * * * /usr/sbin/ntpdate cn.pool.ntp.org

可使用crontab -l命令查看

重启crond服务使配置生效

[rootmaster ~]# systemctl restart crond安装配置
12安装基础软件包 [rootmaster ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 wget net-tools nfs-utils lrzsz gcc gcc-c make cmake libxml2-devel openssl-devel curl curl-devel unzip sudo ntp libaio-devel wget vim ncurses-devel autoconf automake zlib-devel python-devel epel-release openssh-server socat ipvsadm conntrack ntpdate telnet ipvsadm13安装docker服务 a. 安装docker [rootmaster ~]# yum install -y docker-ce-20.10.6 docker-ce-cli-20.10.6 containerd.io

启动docker服务并配置为自启动

[rootmaster ~]# systemctl start docker systemctl enable docker systemctl status docker

running 表示运行状态b. 配置镜像加速器

配置加速器

[rootmaster ~]# vim /etc/docker/daemon.json {registry-mirrors:[https://docker.1ms.run,https://axcmsqgw.mirror.aliyuncs.com,https://registry.docker-cn.com,https://docker.mirrors.ustc.edu.cn,https://dockerhub.azk8s.cn,http://hub-mirror.c.163.com,http://qtid6917.mirror.aliyuncs.com, https://rncxm540.mirror.aliyuncs.com],exec-opts: [native.cgroupdriversystemd] }# 重启docker [rootmaster ~]# systemctl daemon-reload systemctl restart docker14安装初始化k8s需要的软件包 [rootmaster ~]# yum install -y kubelet-1.20.6 kubeadm-1.20.6 kubectl-1.20.6

配置开机自启动先不用启动

[rootmaster ~]# systemctl enable kubelet3.kubeadm初始化k8s 1kubeadm初始化master节点 master节点执行

1.生成配置文件

[rootmaster ~]# kubeadm config print init-defaults kubeadm.yaml# 2.修改配置文件 [rootmaster ~]# vim kubeadm.yaml

advertiseAddress: 172.16.32.144 master节点IP

apiVersion: kubeproxy.config.k8s.io/v1alpha1 kind: KubeProxyConfiguration

mode: ipvs

apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration cgroupDriver: systemd安装完成后需要执行以下命令 [rootmaster ~]# mkdir -p $HOME/.kube [rootmaster ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config [rootmaster ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config配置文件查看 #直接查看 [rootmaster1 scripts]# cat /root/.kube/config

使用kubectl查看

[rootmaster1 scripts]# kubectl config view2查询k8s集群状态 master节点执行 [rootmaster ~]# kubectl get nodes

其他节点查看集群状态需要将master节点/root/.kube/目录下的config文件拷贝到对应服务器/root/.kube/目录下

[rootmaster ~]# kubectl get nodes NAME STATUS ROLES AGE VERSION master NotReady control-plane,master 7m44s v1.20.6

此时集群状态还是NotReady状态因为没有安装网络插件# 查询kube-system命名空间下的所有pod

[rootmaster ~]# kubectl get pods -n kube-system NAME READY STATUS RESTARTS AGE coredns-54d67798b7-9twrv 0/1 Pending 0 8m18s coredns-54d67798b7-q7m7p 0/1 Pending 0 8m18s etcd-master ¹⁄₁ Running 0 8m35s kube-apiserver-master ¹⁄₁ Running 0 8m35s kube-controller-manager-master ¹⁄₁ Running 0 8m35s kube-proxy-k9h8m ¹⁄₁ Running 0 8m18s kube-scheduler-master ¹⁄₁ Running 0 8m34s[rootmaster ~]# kubectl get pods -n kube-system -owide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES coredns-54d67798b7-9twrv 0/1 Pending 0 8m28s none none none none coredns-54d67798b7-q7m7p 0/1 Pending 0 8m28s none none none none etcd-master ¹⁄₁ Running 0 8m45s 172.16.32.144 master none none kube-apiserver-master ¹⁄₁ Running 0 8m45s 172.16.32.144 master none none kube-controller-manager-master ¹⁄₁ Running 0 8m45s 172.16.32.144 master none none kube-proxy-k9h8m ¹⁄₁ Running 0 8m28s 172.16.32.144 master none none kube-scheduler-master ¹⁄₁ Running 0 8m44s 172.16.32.144 master none none3将工作节点添加进集群添加node到k8s集群

在master节点上执行命令生成token

[rootmaster ~]# kubeadm token create –print-join-command kubeadm join 172.16.32.144:6443 –token cy81ds.6286kye4el4wbkl2 –discovery-token-ca-cert-hash sha256:4d4ecc7be2ab3f60f3ab34d7d68dbc27da22393ac684b241f5a4f408169fd1b7

生成的token有效期为24小时

每次添加工作节点的时候都需要执行该命令# 在工作节点上执行生成的命令并添加参数

–ignore-preflight-errorsSystemVerification

[rootnode ~]# kubeadm join 172.16.32.144:6443 –token cy81ds.6286kye4el4wbkl2 –discovery-token-ca-cert-hash sha256:4d4ecc7be2ab3f60f3ab34d7d68dbc27da22393ac684b241f5a4f408169fd1b7 –ignore-preflight-errorsSystemVerification状态查看

将工作节点添加进集群后查询k8s集群状态

[rootmaster ~]# kubectl get nodes NAME STATUS ROLES AGE VERSION master NotReady control-plane,master 12m v1.20.6 node NotReady none 2m22s v1.20.6

工作节点的ROLES默认显示为none若想显示为其他可以通过在master节点指定命令对工作节点生成标签# 打标签

[rootmaster ~]# kubectl label node node node-role.kubernetes.io/node1worker# 删除标签 [rootmaster ~]# kubectl label node node node-role.kubernetes.io/node1-4安装网络插件-Calico

将calico.yaml上传至服务器使用以下命令安装calico

[rootmaster ~]# kubectl apply -f calico.yaml –validatefalse

会自动拉取calico/pod2daemon-flexvol:v3.18.0、calico/cni:v3.18.0、calico/node:v3.18.0镜像# 查看nodes状态显示为ready即表示成功

[rootmaster ~]# kubectl get nodes NAME STATUS ROLES AGE VERSION master Ready control-plane,master 18m v1.20.6

达内网站开发荆州网站建设 众火网

node节点配置与上述配置除IP外其余相同# 重启网络

临时关闭

将SELINUX设置为disabled

检查修改状态

修改服务器的/etc/hosts文件增加如下两行

临时关闭

永久关闭

/dev/mapper/centos-swap swap swap defaults 0 0

关闭后需要重启服务器否则在初始化k8s时候会报错7修改内核参数

加载模块

修改内核参数创建docker.conf文件并写入内核参数

使参数生效

或 [rootmaster ~]# systemctl disable firewalld –now9配置阿里云repo源

默认yum源无法使用需要更换成国内yum源演示为阿里云yum源# 备份基础repo源

把CentOS-Base.repo文件上传到各个主机的/etc/yum.repos.d/目录下具体内容参考下述CentOS-Base.repo文件内容

安装rzsz

配置国内阿里云docker的repo源

安装ntp服务

同步时间若存在本地时间服务器可将cn.pool.ntp.org换成时间服务器IP

编写计划任务

可使用crontab -l命令查看

重启crond服务使配置生效

启动docker服务并配置为自启动

running 表示运行状态b. 配置镜像加速器

配置加速器

配置开机自启动先不用启动

1.生成配置文件

advertiseAddress: 172.16.32.144 master节点IP

name: master master节点主机名

imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers 阿里云镜像仓库

kubernetesVersion: v1.20.6 k8s版本

serviceSubnet: 10.96.0.0/12 service网段

podSubnet: 10.244.0.0/16 新增pod网段

criSocket: /var/run/dockershim.sock 容器运行池

在scheduler: {}下一行新增以下配置

mode: ipvs

初始化时会自动拉取相关镜像

nodeRegistration:criSocket: /var/run/dockershim.sockname: mastertaints:- effect: NoSchedulekey: node-role.kubernetes.io/master

scheduler: {}

mode: ipvs

使用kubectl查看

其他节点查看集群状态需要将master节点/root/.kube/目录下的config文件拷贝到对应服务器/root/.kube/目录下

此时集群状态还是NotReady状态因为没有安装网络插件# 查询kube-system命名空间下的所有pod

在master节点上执行命令生成token

生成的token有效期为24小时

每次添加工作节点的时候都需要执行该命令# 在工作节点上执行生成的命令并添加参数

–ignore-preflight-errorsSystemVerification

将工作节点添加进集群后查询k8s集群状态

工作节点的ROLES默认显示为none若想显示为其他可以通过在master节点指定命令对工作节点生成标签# 打标签

将calico.yaml上传至服务器使用以下命令安装calico

会自动拉取calico/pod2daemon-flexvol:v3.18.0、calico/cni:v3.18.0、calico/node:v3.18.0镜像# 查看nodes状态显示为ready即表示成功

显示为初始化k8s时kubeadm.yaml配置文件中的service网段4.安装dashboard

显示kubernetes-dashboard表示成功[rootmaster ~]# kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard

将type的值由ClusterIP修改为NodePort[rootmaster ~]# kubectl get svc -n kubernetes-dashboard
