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

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

- 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:
