二、上传镜像到harbor【deploy上操作】
说明：harbor安装方法参考次篇文章https://www.cnblogs.com/douyi/p/12057218.html
1：mysql镜像push到harbor上
1 [root@master ~]# docker tag mysql:5.7 harbor.ghs.com/lnmp/mysql:5.7 2 [root@master ~]# docker push harbor.ghs.com/lnmp/mysql:5.7 3 The push refers to repository [harbor.ghs.com/lnmp/mysql] 494a471180601: Pushed 5934de0c0816e: Pushed 6fc12e028de3b: Pushed 7398ef8a407f7: Pushed 87055b7f82e4c: Pushed 92a9aab74013a: Pushed 10414373ffccb4: Pushed 116599033b2ab2: Pushed 1251734435c93c: Pushed 135a8a245abd1c: Pushed 1499b5261d397c: Pushed 155.7: digest: sha256:9e02c7c9a87d363588e85c87b8c6f637254c5c67b915b1666482f54121bb0926 size: 2622
2：nginx-php-fpm镜像push到harbor上
1 [root@master ~]# docker tag richarvey/nginx-php-fpm harbor.ghs.com/lnmp/nginx-php-fpm:latest 2 [root@master ~]# docker push harbor.ghs.com/lnmp/nginx-php-fpm:latest 3 The push refers to repository [harbor.ghs.com/lnmp/nginx-php-fpm] 42624e7202e4b: Pushed 5eb30cdb90ca1: Pushed 6ae93c067c849: Pushed 79801a5392a22: Pushed 87b2d66211161: Pushed 99d4627716f06: Pushed 10d3cf99377a74: Pushed 11f647f7714c77: Pushed 128ed73ab2d11b: Pushed 13525bffddcce1: Pushed 14d93022710c58: Pushed 1528e868b9a611: Pushed 16ebbffb8bead8: Pushed 17c4ffba011c55: Pushed 189ac09047b17d: Pushed 193fefc401e422: Pushed 203b73d52fb480: Pushed 2173f0a2737684: Pushed 22bb46af78e4a5: Pushed 235d02268e182d: Pushed 2484bd64e5da78: Pushed 2514d91eeebaab: Pushed 2667ee9b354071: Pushed 27d822f3d53ee3: Pushed 28a0c85631af8f: Pushed 297c1ad7fa7002: Pushed 3003ecc22184eb: Pushed 311581c77670a3: Pushed 3214ee8729351c: Pushed 3303901b4a2ea8: Pushed 34 latest: digest: sha256:f8109029deb401ee83c4fcd1e737cc496f42aca6a6e8f445f8501ea977be6784 size: 6576
三、安装NFS【master2上操作】
1：创建web和DB目录
##/data/k8s下的两个目录用于集群中运行LNMP环境存放的数据，web目录为nginx网站的根目录，DB为数据库存放的数据目录
[root@master2 ~]# mkdir -p /data/k8s/{web,db}
2：yum安装nfs
[root@master2 ~]# yum -y install nfs-utils
3：设置共享目录
[root@master2 ~]# vim /etc/exportfs
/data/k8s 192.168.1.0/24(sync,rw,no_root_squash)
4：启动服务
[root@master2 ~]# systemctl start nfs
[root@master2 ~]# systemctl enable nfs
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.
四、安装Mysql服务【deploy上操作】
1：创建存放mysql服务的yaml文件目录
[root@master2 ~]# mkdir -p /home/k8s/lnmp/mysql
2：创建secret，将mysql数据库的密码存放到secret中
[root@master mysql]# kubectl create secret generic mysql-pass --from-literal=password=abc123
3：创建mysql-pv
1 [root@master mysql]# vim mysql-pv.yaml 2apiVersion: v1 3kind: PersistentVolume 4metadata: 5 name: mysql-pv 6spec: 7 capacity: 8 storage: 10Gi 9 accessModes: 10 - ReadWriteMany 11 nfs: 12 path: /data/k8s/db ##该参数指定你的NFS端的共享目录 13 server: 192.168.1.201 ##指定nfs端的IP 14 [root@master mysql]# kubectl create -f mysql-pv.yaml 15 persistentvolume/mysql-pv created
4：创建mysql-pvc
1 [root@master mysql]# vim mysql-pvc.yaml 2apiVersion: v1 3kind: PersistentVolumeClaim 4metadata: 5 name: mysql-claim 6 labels: 7 app: discuz 8spec: 9 accessModes: 10 - ReadWriteMany 11 resources: 12 requests: 13 storage: 10Gi 14 [root@master mysql]# kubectl create -f mysql-pvc.yaml 15 persistentvolumeclaim/mysql-claim created
5：查看pv，pvc信息
##下面可以看出状态Bound（绑定）正常，pv中的CLAIM列绑定的信息为pvc定义的name，pvc中VOLUME列的信息显示绑定了mysql-pv的name
1[root@master mysql]# kubectl get pv,pvc 2NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE 3 persistentvolume/mysql-pv 10Gi RWX Retain Bound default/mysql-claim 71s 45NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE 6 persistentvolumeclaim/mysql-claim Bound mysql-pv 10Gi RWX 15s
6：创建mysql-deploy
1 [root@master mysql]# vim mysql-dp.yaml 2 apiVersion: apps/v1 3kind: Deployment 4metadata: 5 name: dz-mysql 6 labels: 7 app: discuz 8spec: 9 selector: 10 matchLabels: 11 app: discuz 12 tier: mysql 13 strategy: 14 type: Recreate 15 template: 16 metadata: 17 labels: 18 app: discuz 19 tier: mysql 20 spec: 21 imagePullSecrets: 22 - name: my-secret 23 containers: 24 - image: harbor.ghs.com/lnmp/mysql:5.7 ##此处指定你的harbor需要拉取的镜像 25 name: mysql 26env: 27 - name: MYSQL_ROOT_PASSWORD 28 valueFrom: 29 secretKeyRef: 30 name: mysql-pass ##此模块是调用secret中存放的mysql密码 31 key: password 32 ports: 33 - containerPort: 330634 name: dz-mysql 35 volumeMounts: 36 - name: mysql-persistent-storage 37 mountPath: /var/lib/mysql 38 volumes: 39 - name: mysql-persistent-storage 40 persistentVolumeClaim: ##此模块参数调用定义创建的pvc名称 41 claimName: mysql-claim 42 [root@master mysql]# kubectl create -f mysql-dp.yaml 43 deployment.apps/dz-mysql created

8：查看mysql服务的pod和svc信息
##下面信息可以看出，dz-mysql状态Running（运行）正常，分配的cluster-ip=10.68.235.35，该IP在集群中可以访问，外部无法访问该IP
1[root@master mysql]# kubectl get pod,svc 2NAME READY STATUS RESTARTS AGE 3 pod/dz-mysql-787586b8d6-9kl5b 1/1 Running 0 5m35s 4 pod/nginx-7c45b84548-4998z 1/1 Running 2 20d 56 NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE 7 service/dz-mysql ClusterIP 10.68.235.35 <none> 3306/TCP 5m13s 8 service/kubernetes ClusterIP 10.68.0.1 <none> 443/TCP 20d 9 service/nginx ClusterIP 10.68.241.175 <none> 80/TCP 20d
五、安装Nginx服务【deploy上操作】
1：创建nginx-pv
1 [root@master nginx]# vim web-pv.yaml 2apiVersion: v1 3kind: PersistentVolume 4metadata: 5 name: web-pv 6spec: 7 capacity: 8 storage: 10Gi 9 accessModes: 10 - ReadWriteMany 11 nfs: 12 path: /data/k8s/web 13 server: 192.168.1.20114 [root@master nginx]# kubectl create -f web-pv.yaml 15 persistentvolume/web-pv created

六、安装Discuz【NFS上操作】
1：下载Discuz
1 [root@master2 ~]# cd /data/ 2 [root@master2 data]# git clone https://gitee.com/ComsenzDiscuz/DiscuzX.git3 正克隆到 ‘DiscuzX‘... 4 remote: Counting objects: 9085, done. 5 remote: Compressing objects: 100% (5400/5400), done. 6 remote: Total 9085 (delta 3895), reused 8535 (delta 3632) 7 接收对象中: 100% (9085/9085), 12.96 MiB | 166.00 KiB/s, done. 8 处理 delta 中: 100% (3895/3895), done.
2：将Discuz项目中upload目录下所有文件，放到web中
1 [root@master2 data]# mv DiscuzX/upload/* k8s/web/ 2[root@master2 data]# cd k8s/web/ 3[root@master2 web]# chmod 100 data uc_server/data uc_client/data config
3：进入mysql，创建dz库和授权用户
1 [root@master ~]# kubectl exec -it dz-mysql-787586b8d6-9kl5b -- mysql -u root -p 2Welcome to the MySQL monitor. Commands end with ; or \g. 3 Your MySQL connection id is 4 4 Server version: 5.7.28 MySQL Community Server (GPL) 5 6 Copyright (c) 2000, 2019, Oracle and/or its affiliates.

Type ‘\c‘ to clear the current input statement. 1314 mysql> create database dz; 15 Query OK, 1 row affected (0.19 sec) 1617 mysql> grant all on dz.* to ‘dz‘@‘%‘ identified by ‘abc123‘; 18 Query OK, 0 rows affected, 1 warning (0.11 sec
4：浏览器访问web安装页面
实验成功
5：通过设置Nginx代理供外部访问
##目前nginx服务是运行在kubernetes集群里，node节点以及master节点上是可以通过cluster-ip访问到，但是外部的客户端就不能访问了。所以，可以在任意一台node或者master上建一个nginx反向代理即可访问到集群内的nginx。 kubectl get svc dz-web //查看cluster-ip，我的ip是10.68.235.35
nginx代理配置文件内容如下：
1server { 2 listen 80; 3 server_name dz.yuankeedu.com; 4 5 location / { 6 proxy_pass http://10.68.235.35; 7 proxy_set_header Host $host; 8 proxy_set_header X-Real-IP $remote_addr; 9 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 10 } 11 }
