1 下载MySQL、PHP以及Nginx镜像
docker pull mysql:5.7
docker pull richarvey/nginx-php-fpm
2 将下载到的镜像push到harbor
docker tag mysql:5.7 harbor.yuankeedu.com/aminglinux/mysql:5.7
docker push harbor.yuankeedu.com/aminglinux/mysql:5.7
docker tag aming-nginx-php harbor.yuankeedu.com/aminglinux/nginx-php
docker push harbor.yuankeedu.com/aminglinux/nginx-php
3 搭建NFS服务
yum install nfs-utils
vim /etc/exportfs
/data/k8s/ 172.7.5.0/24(sync,rw,no_root_squash)
systemctl start nfs
systemctl enable nfs
mkdir -p /data/k8s/discuz/{db,web}
4 搭建MySQL服务
1)创建secretkubectl create secret generic mysql-pass --from-literal=password=DzPasswd123
2)创建pv
vim mysql-pv.yaml //内容如下
apiVersion: v1
kind: PersistentVolume
metadata:
name: mysql-pv
spec:
capacity:
storage: 10Gi
accessModes:
- ReadWriteMany
nfs:
path: /data/k8s/discuz/db
server: 172.7.5.113
kubectl create -f mysql-pv.yaml
3)创建pvc
vim mysql-pvc.yaml //内容如下
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mysql-claim
labels:
app: discuz
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 10Gi
kubectl create -f mysql-pvc.yaml
4)创建deployment
vim mysql-dp.yaml //内容如下

- name: mysql-persistent-storage
mountPath: /var/lib/mysql
volumes:
- name: mysql-persistent-storage
persistentVolumeClaim:
claimName: mysql-claim
kubectl create -f mysql-dp.yaml
5)创建service
vim mysql-svc.yaml
apiVersion: v1
kind: Service
metadata:
name: dz-mysql
labels:
app: discuz
spec:
ports:
- port: 3306
selector:
app: discuz
tier: mysql
kubectl create -f mysql-svc.yaml
5 搭建nginx+php-fpm服务
1)创建pv
vim web-pv.yaml //内容如下
apiVersion: v1
kind: PersistentVolume
metadata:
name: web-pv
spec:
capacity:
storage: 10Gi
accessModes:
- ReadWriteMany
nfs:
path: /data/k8s/discuz/web
server: 172.7.5.113
kubectl create -f web-pv.yaml
2)创建pvc
vim web-pvc.yaml //内容如下
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: web-claim
labels:
app: discuz
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 10Gi
kubectl create -f web-pvc.yaml
3)创建deployment
vim web-dp.yaml //内容如下
apiVersion: apps/v1
kind: Deployment
metadata:
name: dz-web
labels:
app: discuz
spec:
replicas: 1
selector:
matchLabels:
app: discuz
tier: nginx-php
template:
metadata:
labels:
app: discuz
