一、基础配置

1.修改主机名

hostnamectl set-hostname k8s-master01
hostnamectl set-hostname k8s-master02
hostnamectl set-hostname k8s-master03
hostnamectl set-hostname k8s-node01
hostnamectl set-hostname k8s-node02

2.添加 主机名与IP地址解析

cat > /etc/hosts <<EOF
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.1.62 lookup apiserver.cluster.local
192.168.1.60 k8s-master01
192.168.1.61 k8s-master02
192.168.1.62 k8s-master03
192.168.1.63 k8s-node01
192.168.1.64 k8s-node02
EOF

3.升级服务器内核，时间同步，关闭防火墙，重启服务器

#添加访问互联路由
cat > /etc/resolv.conf <<EOF
nameserver 114.114.114.114
nameserver 8.8.8.8
EOFcat /etc/resolv.conf# ssh连接Linux比较慢
#sed -i "s|#UseDNS yes|UseDNS no|" /etc/ssh/sshd_config

EOFmodprobe ip_vs_rr && modprobe br_netfilter && sysctl -p /etc/sysctl.d/kubernetes.conf#关闭系统不需要服务
systemctl stop postfix && systemctl disable postfix

4.升级内核，重启服务器

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.orgyum -y install https://www.elrepo.org/elrepo-release-7.0-4.el7.elrepo.noarch.rpmyum --enablerepo="elrepo-kernel" -y install kernel-lt.x86_64awk -F \' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg
grub2-set-default "CentOS Linux (5.4.225-1.el7.elrepo.x86_64) 7 (Core)"
#grub2-set-default 'CentOS Linux (4.4.222-1.el7.elrepo.x86_64) 7 (Core)'
#重启服务器
reboot
################################

二、sealos部署k8s-v1.19

1.安装sealos3.3

#添加访问互联路由
cat > /etc/resolv.conf <<EOF
nameserver 8.8.8.8
nameserver 114.114.114.114
nameserver 223.5.5.5
EOFcat /etc/resolv.conf#时间同步
ntpdate ntp1.aliyun.comwget -c https://github.com/fanux/sealos/releases/download/v3.3.8/sealostar zxvf sealos*.tar.gz sealos && chmod +x sealos && mv sealos /usr/binsealos version#时间同步
ntpdate ntp1.aliyun.com

2.离线安装k8s 1.19

链接：https://pan.baidu.com/s/1F9sZoHBX1K1ihBP9rZSHBQ?pwd=jood
提取码：jood#安装
sealos init --passwd 1qaz@WSX \--master 192.168.1.60 \--master 192.168.1.61 \--master 192.168.1.62 \--node 192.168.1.63 \--node 192.168.1.64 \--pkg-url /root/kube1.19.16.tar.gz \--version v1.19.16

3.验证集群

kubectl get nodeskubectl get pod -A#配置kubectl自动补全
yum install -y bash-completion
source /usr/share/bash-completion/bash_completion
source <(kubectl completion bash)
echo "source <(kubectl completion bash)" >> /etc/profile#查看污点
kubectl describe node |grep -i taints#去除污点#kubectl taint node k8s-master02 node-role.kubernetes.io/master:NoSchedule-
#kubectl taint node k8s-master03 node-role.kubernetes.io/master:NoSchedule-

4.sealos3.3常用命令

#添加 node 节点：
sealos join --node 192.168.1.63,192.168.1.64#添加master
sealos join -master 192.168.1.61,192.168.1.62#删除 node 节点：
sealos clean --node 192.168.1.63,192.168.1.64#删除 master 节点：
sealos clean --master 192.168.1.61,192.168.1.62#重置集群
sealos clean --all -f

5.安装top命令

三、部署nfs

1.服务端

#添加访问互联路由
cat > /etc/resolv.conf <<EOF
nameserver 114.114.114.114
nameserver 8.8.8.8
EOF# 我们这里在192.168.1.60上安装（在生产中，大家要提供作好NFS-SERVER环境的规划）
yum -y install nfs-utils# 创建NFS挂载目录
mkdir /nfs_dir
chown nobody.nobody /nfs_dir# 修改NFS-SERVER配置
echo '/nfs_dir *(rw,sync,no_root_squash)' > /etc/exports# 重启服务
systemctl restart rpcbind.service
systemctl restart nfs-utils.service
systemctl restart nfs-server.service # 增加NFS-SERVER开机自启动
systemctl enable  rpcbind.service
systemctl enable  nfs-utils.service
systemctl enable  nfs-server.service # 验证NFS-SERVER是否能正常访问
#showmount -e 192.168.1.60               

2.客户端

#需要挂载的服务器执行
mkdir /nfs_dir
yum install nfs-utils -y#挂载
mount 192.168.1.60:/nfs_dir /nfs_dir#添加开机挂载
echo "mount 192.168.1.60:/nfs_dir /nfs_dir" >> /etc/rc.localcat /etc/rc.local

四、部署StorageClass

1.创建nfs-sc.yaml

cat > /root/nfs-sc.yaml <<EOF
apiVersion: v1

五、harbor仓库搭建

1.安装

#目录/root上传文件docker-compose和harbor-offline-installer-v1.2.0.tgzmv /root/docker-compose /usr/local/bin/
chmod a+x /usr/local/bin/docker-composeln -s /usr/local/bin/docker-compose /usr/bin/docker-composetar -zxvf harbor-offline-installer-v2.4.1.tgzmv harbor /usr/local/cd /usr/local/harbor/cp harbor.yml.tmpl harbor.ymlsed -i 's/hostname: reg.mydomain.com/hostname: 192.168.1.77/g' harbor.yml
sed -i 's/https/#https/g' harbor.yml
sed -i 's/certificate/#certificate/g' harbor.yml
sed -i 's/private_key/#private_key/g' harbor.yml#数据库目录
mkdir /datacat /etc/docker/daemon.json
{"registry-mirrors": ["https://nr240upq.mirror.aliyuncs.com", "https://registry.docker-cn.com", "https://docker.mirrors.ustc.edu.cn", "https://dockerhub.azk8s.cn", "http://hub-mirror.c.163.com"],"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"insecure-registries": ["192.168.1.77:80"]
}systemctl daemon-reload && systemctl restart docker#安装
./install.sh## 重启harbor
cd /usr/local/harbor/
docker-compose down -v
docker-compose up -d
docker ps|grep harbor
netstat -ntlp

2.需要访问仓库的其他节点的 daemon.json添加如下内容

##-------------------
vim /etc/docker/daemon.json"registry-mirrors": ["https://nr240upq.mirror.aliyuncs.com", "https://registry.docker-cn.com", "https://docker.mirrors.ustc.edu.cn", "https://dockerhub.azk8s.cn"],"insecure-registries": ["192.168.1.77:80"],##-------------------#重启
systemctl daemon-reload && systemctl restart docker

3.节点使用仓库

#登入仓库网站docker login -u admin -p Harbor12345 192.168.1.77:80#下载镜像
docker pull daocloud.io/library/nginx:1.9.1#给镜像打上标签
docker tag daocloud.io/library/nginx:1.9.1 192.168.1.77:80/library/nginx:1.9.1#镜像上传
docker push 192.168.1.77:80/library/nginx:1.9.1#删除镜像
docker rmi 192.168.1.77:80/library/nginx:1.9.1#将镜像保存为本地tar文件，
docker save k8s.gcr.io/coredns:1.7.0  > /root/coredns-v1.7.0.tar #使用load加载tar文件
docker load -i  /root/coredns-v1.7.0.tar

4.批量打包上传harbor镜像

cd /root
#查看服务器镜像名称
docker images | awk 'NR!=1{print $1":"$2}' > 01-image-old.txt && cat 01-image-old.txt# /换成-
rm -rf  02-image-sed.txt && cp 01-image-old.txt 02-image-sed.txt && sed -i  "s|/|-|g" 02-image-sed.txt  && cat /root/02-image-sed.txt#打标签harbor仓库vim /root/03-tar-image.sh
#####################################################
#!/bin/sh
old=/root/01-image-old.txt
new=/root/02-image-sed.txt
l=$(cat /root/01-image-old.txt| wc -l)
for ((i=1 ; i<=$l ; i++))
do
a=$(sed -n "$i"p $old)
b=$(sed -n "$i"p $new)
#echo "update xxxx  set uid='$a' where uid='$b';"
docker tag $a 192.168.1.77:80/library/$b
done
######################################################运行打仓库标签
bash /root/03-tar-image.shdocker images |grep library#查看打标harbor仓库images名称
docker images |grep 192.168.1.77 | awk '{print $1":"$2}'  > 04-tar-image.txt && cat 04-tar-image.txt#上传到harbor仓库
for h in `cat 04-tar-image.txt`; do docker push $h; done#删除打标镜像
for d in `cat 04-tar-image.txt`; do docker rmi $d; done
docker images |grep library#删除创建的文件
rm -rf /root/0*txt  03-tar-image.sh

六、kuboard界面管理

1.下载地址

curl -o kuboard-v3.yaml https://addons.kuboard.cn/kuboard/kuboard-v3-storage-class.yaml

2.编辑yaml

#编辑 kuboard-v3.yaml 文件中的配置，该部署文件中，有1处配置必须修改：storageClassNamevolumeClaimTemplates:- metadata:name: dataspec:# 请填写一个有效的 StorageClass namestorageClassName: nfs-bogeaccessModes: [ "ReadWriteMany" ]resources:requests:storage: 5Gi

3.执行

kubectl create -f kuboard-v3.yamlkubectl get pod -n kuboard#############################################访问

十、Prometheus监控

1.导入离线包

链接：https://pan.baidu.com/s/1DyMJPT8r_TUpI8Dr31SVew?pwd=m1bk
提取码：m1bk#导入上传tar包
sudo docker load -i alertmanager-v0.21.0.tar
sudo docker load -i grafana-7.3.4.tar
sudo docker load -i k8s-prometheus-adapter-v0.8.2.tar
sudo docker load -i kube-rbac-proxy-v0.8.0.tar
sudo docker load -i kube-state-metrics-v1.9.7.tar
sudo docker load -i node-exporter-v1.0.1.tar
sudo docker load -i prometheus-config-reloader-v0.43.2.tar
sudo docker load -i prometheus_demo_service.tar
sudo docker load -i prometheus-operator-v0.43.2.tar
sudo docker load -i prometheus-v2.22.1.tar

2.主节点创建

#解压下载的代码包
sudo unzip kube-prometheus-master.zip
sudo rm -f kube-prometheus-master.zip && cd kube-prometheus-master#这里建议先看下有哪些镜像，便于在下载镜像快的节点上先收集好所有需要的离线docker镜像
find ./ -type f |xargs grep 'image: '|sort|uniq|awk '{print $3}'|grep ^[a-zA-Z]|grep -Evw 'error|kubeRbacProxy'|sort -rn|uniqkubectl create -f manifests/setup
kubectl create -f manifests/#过一会查看创建结果：
kubectl -n monitoring get all# 附：清空上面部署的prometheus所有服务：
# kubectl delete --ignore-not-found=true -f manifests/ -f manifests/setup

3. 访问下prometheus的UI

# 修改下prometheus UI的service模式，便于我们访问
# kubectl -n monitoring patch svc prometheus-k8s -p '{"spec":{"type":"NodePort"}}'
service/prometheus-k8s patched# kubectl -n monitoring get svc prometheus-k8s
NAME             TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE
prometheus-k8s   NodePort   10.68.23.79   <none>        9090:22129/TCP   7m43s

3.1 修改用户权限

#   kubectl edit clusterrole prometheus-k8s
#------ 原始的rules -------
rules:
- apiGroups:- ""resources:- nodes/metricsverbs:- get
- nonResourceURLs:- /metricsverbs:- get
#---------------------------apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:name: prometheus-k8s
rules:
- apiGroups:- ""resources:- nodes- services- endpoints- pods- nodes/proxyverbs:- get- list- watch
- apiGroups:- ""resources:- configmaps- nodes/metricsverbs:- get
- nonResourceURLs:- /metricsverbs:- get

4. 监控ingress-nginx

cat > servicemonitor.yaml <<EOF
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:labels:app: ingress-nginxname: nginx-ingress-scrapingnamespace: ingress-nginx
spec:endpoints:- interval: 30spath: /metricsport: metricsjobLabel: appnamespaceSelector:matchNames:- ingress-nginxselector:matchLabels:app: ingress-nginx
EOFkubectl apply -f servicemonitor.yamlkubectl -n ingress-nginx get servicemonitors.monitoring.coreos.com

十一、安装kubesphere3.3

官网参考文档

https://kubesphere.com.cn/docs/v3.3/pluggable-components/alerting/

1.部署kubesphere时需要默认 StorageClass

kubectl edit sc nfs-boge

  metadata:annotations:storageclass.beta.kubernetes.io/is-default-class: "true"

2.下载yaml

wget https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/kubesphere-installer.yamlwget https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/cluster-configuration.yaml#修改cluster-configuration.yaml
#将ectd下的 endpointIps改为你的master节点的私有IP地址。
#endpointIps: XX.X.X.X

3.运行yaml

kubectl apply -f kubesphere-installer.yamlkubectl apply -f cluster-configuration.yaml

4. 查看日志

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f#访问任意机器的 30880端口
#账号 ： admin
#密码 ： P@88w0rd

5. 解决etcd监控证书找不到问题

kubectl -n kubesphere-monitoring-system create secret generic kube-etcd-client-certs  \
--from-file=etcd-client-ca.crt=/etc/kubernetes/pki/etcd/ca.crt  \
--from-file=etcd-client.crt=/etc/kubernetes/pki/etcd/healthcheck-client.crt  \
--from-file=etcd-client.key=/etc/kubernetes/pki/etcd/healthcheck-client.key

6. 在安装后启用告警系统,

在 cluster-configuration.yaml 文件中，搜索 alerting，将 enabled 的 false 更改为 true 以启用告警系统。完成后保存文件

alerting:enabled: true # 将“false”更改为“true”。#运行
kubectl apply -f kubesphere-installer.yamlkubectl apply -f cluster-configuration.yaml

6.0 配置钉钉报警

6.1 钉钉自定义机器配置

添加自定义机器人，安全配置，勾选** 加签**

6.2 操作步骤

左上角>平台管理>平台设置>通知管理>通知配置>钉钉>群机器人配置
开启-已启用
填写自己的 Webhook URL
填写自己的 密钥 （加签）

查看钉钉群消息.是否发送成功？？？？？

7. 在安装后启用应用商店，

在该 YAML 文件中，搜索 openpitrix，将 enabled 的 false 改为 true。完成后，点击右下角的确定，保存配置。

openpitrix:store:enabled: true # 将“false”更改为“true”。#运行
kubectl apply -f kubesphere-installer.yamlkubectl apply -f cluster-configuration.yaml

8.在安装后启用服务网格 istio

在该配置文件中，搜索 servicemesh，并将 enabled 的 false 改为 true。完成后，点击右下角的确定，保存配置

servicemesh:
enabled: true # 将“false”更改为“true”。
istio: # Customizing the istio installation configuration, refer to https://istio.io/latest/docs/setup/additional-setup/customize-installation/components:ingressGateways:- name: istio-ingressgateway # 将服务暴露至服务网格之外。默认不开启。enabled: falsecni:enabled: false # 启用后，会在 Kubernetes pod 生命周期的网络设置阶段完成 Istio 网格的 pod 流量转发设置工作。

9.在安装前启用 DevOps

在该 YAML 文件中，搜索 devops，将 enabled 的 false 改为 true。完成后，点击右下角的确定，保存配置。

devops:enabled: true # 将“false”更改为“true”。

10. 卸载方法

kubectl delete -f cluster-configuration.yaml --force
kubectl delete -f kubesphere-installer.yaml --force

#删除残余文件
vi del.sh

#!/usr/bin/env bashfunction delete_sure(){cat << eof

十二、 GitLab安装

1. 单独准备服务器，采用Docker安装

docker search gitlab
docker pull gitlab/gitlab-ce

2.准备docker-compose.yml文件

mkdir -p /data/gitvim /data/git/docker-compose.ymlversion: '3.1'
services:gitlab:image: 'gitlab/gitlab-ce:latest'container_name: gitlabrestart: alwaysenvironment:GITLAB_OMNIBUS_CONFIG: |external_url 'http://10.1.100.225:8929'#自己安装git的服务器IPgitlab_rails['gitlab_shell_ssh_port'] = 2224ports:- '8929:8929'- '2224:2224'volumes:- './config:/etc/gitlab'- './logs:/var/log/gitlab'- './data:/var/opt/gitlab'

3.启动容器（需要稍等很久……）

cd /data/git
docker-compose up -d

4.访问GitLab首页

http://10.1.100.225:8929

5.查看root用户初始密码

docker exec -it gitlab cat /etc/gitlab/initial_root_password

6.第一次登录网页，需要修改密码 Password

**右上角>>**Administrator>Preferences>Password

十三、DevOps初始化环境

1.linux系统 安装Jenkins、jdk 、maven

1.下载地址

JDK包下载地址
https://www.oracle.com/java/technologies/downloads/

MAven下载地址
https://maven.apache.org/download.cgi

2.安装jdk maven

tar -zxvf jdk-8*.tar.gz -C /usr/local/
tar -zxvf apache-maven-*.tar.gz -C /usr/local/cd /usr/local
mv apache-maven*/ maven
mv jdk1.8*/ jdk

2.1 编辑maven配置

vim /usr/local/maven/conf/settings.xml

<!--#maven配置阿里云仓库,在160行插入-->
<mirror><id>nexus-aliyun</id><mirrorOf>central</mirrorOf><name>Nexus aliyun</name><url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror><!--#maven配置jdk,在252行插入-->
<profile>    <id>jdk1.8</id>    <activation>    <activeByDefault>true</activeByDefault>    <jdk>1.8</jdk>    </activation>    <properties>    <maven.compiler.source>1.8</maven.compiler.source>    <maven.compiler.target>1.8</maven.compiler.target>    <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>    </properties>
</profile> <!--#maven配置jdk,在257行插入--><activeProfiles><activeProfile>jdk1.8</activeProfile></activeProfiles>

3.安装jenkins

3.1 下载

docker pull jenkins/jenkins:2.319.1-lts

3.2 创建yaml

mkdir -p /data/jenkins/
cd /data/jenkins/
vim /data/jenkins/docker-compose.yml

version: "3.1"
services:jenkins:image: jenkins/jenkinscontainer_name: jenkinsports:- 8080:8080- 50000:50000volumes:- ./data/:/var/jenkins_home/- /var/run/docker.sock:/var/run/docker.sock- /usr/bin/docker:/usr/bin/docker- /etc/docker/daemon.json:/etc/docker/daemon.json

3.3 启动jenkins

#修改Jenkins用户权限
cd /var/runchown root:root docker.sock#其他用户有读和写权限
chmod o+rw docker.sockcd /data/jenkins/
docker-compose up -d#授权
chmod 777 /data/jenkins/data/cat /data/jenkins/data/hudson.model.UpdateCenter.xml
#重新启动Jenkins容器后，由于Jenkins需要下载大量内容，但是由于默认下载地址下载速度较慢，
#需要重新设置下载地址为国内镜像站# 清华大学的插件源也可以
# 修改数据卷中的hudson.model.UpdateCenter.xml文件
# 将下载地址替换为http://mirror.esuni.jp/jenkins/updates/update-center.json# 清华大学的插件源也可以
#https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json#重启
docker-compose restart#查看日志
docker logs -f jenkins

3.4 访问页面，安装插件
