注意观察：他们两个所属的命名空间不同
测试主机hosts文件添加域名
hosts里添加 域名
访问
tomcat商城，访问成功
三、持久化存储（pvc和pv）
1、nfs共享目录文件
1、以k8s的控制节点 master 作为NFS服务端
[root@k8s-master ~]# yum install -y nfs-utils2、所有 node 节点 都下载 nfs 服务
启用nfs服务
yum install nfs-utils -y
systemctl enable --now nfs3、在宿主机创建NFS需要的共享目录
在 根下 创建
[root@k8s-master nginx]# cd /data
[root@k8s-master data]# ls
[root@k8s-master data]# mkdir discuz -pv
mkdir: 已创建目录 'discuz'
[root@k8s-master data]# mkdir tomcat -pv
mkdir: 已创建目录 'tomcat'
[root@k8s-master data]# mkdir mysql/master -p
[root@k8s-master data]# ls
discuz mysql tomcat
[root@k8s-master data]# tree mysql/
mysql/
└── master
2 directories, 0 files
[root@k8s-master data]# mkdir mysql/slave -p
[root@k8s-master data]# mkdir redis -pv
mkdir: 已创建目录 'redis'
[root@k8s-master redis]# mkdir master -pv
mkdir: 已创建目录 'master'
[root@k8s-master redis]# mkdir slave -pv
mkdir: 已创建目录 'slave'
4、配置nfs共享服务器上的/data目录
配置好后保存退出
启用nfs 服务
[root@k8s-master ~]# vim /etc/exports
[root@k8s-master ~]# systemctl enable --now nfs
5、使 nfs 配置生效
[root@k8s-master ~]# exportfs -arv

/data/discuz 192.168.158.0/24
/data 192.168.158.0/24
2、mysql 可持久化
1.生成 pv 对应共享目录
[root@k8s-master ~]# vim pv.yaml
[root@k8s-master ~]# cat pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: mysql-master
spec:
capacity:
storage: 10Gi
accessModes: ["ReadWriteMany"]
nfs:
path: /data/mysql/master
server: 192.168.158.33
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: mysql-slave
spec:
capacity:
storage: 10Gi
accessModes: ["ReadWriteMany"]
nfs:
path: /data/mysql/slave
server: 192.168.158.33
2.提交资源清单生成 pv
[root@k8s-master ~]# kubectl apply -f pv.yaml
persistentvolume/mysql-master unchanged
persistentvolume/mysql-slave unchanged
3.生成对应pvc 对应 pv
[root@k8s-master ~]# vim pvc.yaml
[root@k8s-master ~]# cat pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mysql-master-pvc
namespace: mysql
spec:
accessModes: ["ReadWriteMany"]
resources:
requests:
storage: 5Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mysql-slave-pvc
namespace: mysql
spec:
accessModes: ["ReadWriteMany"]
resources:
requests:
storage: 5Gi
[root@k8s-master ~]# kubectl apply -f pvc.yaml
persistentvolumeclaim/mysql-master-pvc created
persistentvolumeclaim/mysql-slave-pvc created
4.查看
pvc成功挂载pv
查看pv和pvc，STATUS是Bound，表示这个pv已经被pvc绑定了
[root@k8s-master ~]# kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
mysql-master 10Gi RWX Retain Bound mysql/mysql-master-pvc 10m
mysql-slave 10Gi RWX Retain Bound mysql/mysql-slave-pvc 10m
5.修改 mysql 配置文件 对应pvc
1.master （主）
添加如下
volumeMounts:
- name: mysql-master-data
mountPath: /var/lib/mysql
volumes:
- name: mysql-master-data #和这个要一样
persistentVolumeClaim:
claimName: mysql-master-pvc
更新之前先删除pod
[root@k8s-master mysql]# kubectl -n mysql delete pod mysql-master-0
pod "mysql-master-0" deleted
[root@k8s-master mysql]# kubectl apply -f master.yaml
statefulset.apps/mysql-master configured
service/mysql-master unchanged
2.slave（从）
添加如下
volumeMounts:
- name: mysql-slave-data
mountPath: /var/lib/mysql
volumes:
- name: mysql-slave-data #和这个要一样
persistentVolumeClaim:
claimName: mysql-slave-pvc
[root@k8s-master mysql]# kubectl -n mysql delete pod mysql-slave-0
pod "mysql-slave-0" deleted
[root@k8s-master mysql]# kubectl apply -f slave.yaml
statefulset.apps/mysql-slave unchanged
service/mysql-slave unchanged
6.验证
查看数据是否在共享目录中
存在则成功实现持久化
[root@k8s-master ~]# cd /data/mysql/master
[root@k8s-master master]# ls
auto.cnf discuz '#innodb_redo' mysql-bin.000004 private_key.pem undo_002
biyesheji '#ib_16384_0.dblwr' '#innodb_temp' mysql-bin.000005 public_key.pem
ca-key.pem '#ib_16384_1.dblwr' mysql mysql-bin.index server-cert.pem
ca.pem ib_buffer_pool mysql-bin.000001 mysql.ibd server-key.pem
client-cert.pem ibdata1 mysql-bin.000002 mysql.sock sys
client-key.pem ibtmp1 mysql-bin.000003 performance_schema undo_001
[root@k8s-master master]# cd ..
[root@k8s-master mysql]# cd slave/
[root@k8s-master slave]# ls
auto.cnf '#ib_16384_0.dblwr' mysql mysql-relay-bin.000005 public_key.pem
biyesheji '#ib_16384_1.dblwr' mysql-bin.000001 mysql-relay-bin.000006 server-cert.pem
ca-key.pem ib_buffer_pool mysql-bin.000002 mysql-relay-bin.000007 server-key.pem
ca.pem ibdata1 mysql-bin.000003 mysql-relay-bin.index sys
client-cert.pem ibtmp1 mysql-bin.000004 mysql.sock undo_001
client-key.pem '#innodb_redo' mysql-bin.index performance_schema undo_002
discuz '#innodb_temp' mysql.ibd private_key.pem
3、redis 可持久化
1.生成 pv 存储卷
在之前的 pvc.yaml 文件中添加
aapiVersion: v1
kind: PersistentVolume
metadata:
name: redis-master
spec:
capacity:
storage: 10Gi
accessModes: ["ReadWriteMany"]
nfs:
path: /data/redis/master
server: 192.168.158.33
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: redis-slave
spec:
capacity:
storage: 10Gi
accessModes: ["ReadWriteMany"]
nfs:
path: /data/redis/slave
server: 192.168.158.33
2.更新资源清单
bound 绑定了
Available 可用
[root@k8s-master ~]# kubectl apply -f pv.yaml
persistentvolume/mysql-master unchanged
persistentvolume/mysql-slave unchanged
persistentvolume/redis-master created
persistentvolume/redis-slave unchanged
[root@k8s-master ~]# kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
mysql-master 10Gi RWX Retain Bound mysql/mysql-master-pvc 42m
mysql-slave 10Gi RWX Retain Bound mysql/mysql-slave-pvc 42m
redis-master 10Gi RWX Retain Available 5s
redis-slave 10Gi RWX Retain Available 111s
3.生成 pvc 对应 pv
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: redis-master-pvc
namespace: redis
spec:
accessModes: ["ReadWriteMany"]
resources:
requests:
storage: 5Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: redis-slave-pvc
namespace: redis
spec:
accessModes: ["ReadWriteMany"]
resources:
requests:
storage: 5Gi
更新
[root@k8s-master ~]# kubectl apply -f pvc.yaml
persistentvolumeclaim/mysql-master-pvc unchanged
persistentvolumeclaim/mysql-slave-pvc unchanged
persistentvolumeclaim/redis-master-pvc created
persistentvolumeclaim/redis-slave-pvc created
[root@k8s-master ~]# kubectl -n redis get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
redis-master-pvc Bound redis-master 10Gi RWX 10s
redis-slave-pvc Bound redis-slave 10Gi RWX 10s
4.修改redis配置文件对应 pvc
1.master
添加如下
- name: redis-master-data # 挂载配置卷
mountPath: /data # 容器内挂载路径
- name: redis-master-data #和这个要一样
persistentVolumeClaim:
claimName: redis-master-pvc
2.slave
- name: redis-slave-data # 挂载配置卷
mountPath: /data # 容器内挂载路径
- name: redis-slave-data #和这个要一样
persistentVolumeClaim:
claimName: redis-slave-pvc
更新
验证
4、discuz 可持久化
1.生成pv
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: discuz-pv
spec:
capacity:
storage: 10Gi
accessModes: ["ReadWriteMany"]
nfs:
path: /data/discuz
server: 192.168.158.33
更新
[root@k8s-master ~]# kubectl apply -f pv.yaml
persistentvolume/mysql-master unchanged
persistentvolume/mysql-slave unchanged
persistentvolume/redis-master unchanged
persistentvolume/redis-slave unchanged
persistentvolume/discuz-pv created
[root@k8s-master ~]# kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
discuz-pv 10Gi RWX Retain Available 5s
mysql-master 10Gi RWX Retain Bound mysql/mysql-master-pvc 75m
mysql-slave 10Gi RWX Retain Bound mysql/mysql-slave-pvc 75m
redis-master 10Gi RWX Retain Bound redis/redis-master-pvc 20m
redis-slave 10Gi RWX Retain Bound redis/redis-slave-pvc 20m
2.生成pvc 对应pv
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: discuz-pvc
namespace: discuz
spec:
accessModes: ["ReadWriteMany"]
resources:
requests:
storage: 5Gi
更新
[root@k8s-master ~]# vim pvc.yaml
[root@k8s-master ~]# kubectl apply -f pvc.yaml
persistentvolumeclaim/mysql-master-pvc unchanged
persistentvolumeclaim/mysql-slave-pvc unchanged
persistentvolumeclaim/redis-master-pvc unchanged
persistentvolumeclaim/redis-slave-pvc unchanged
persistentvolumeclaim/discuz-pvc created
[root@k8s-master ~]# kubectl -n discuz get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
discuz-pvc Bound discuz-pv 10Gi RWX 12s
3.修改discuz配置文件
/root/dt/nginx/discuz/upload/config
vim config_global_default.php 
vim config_ucenter_default.php 
4.在共享目录中添加对应文件
修改属主和属组
修改配置文件 对应 pvc
spec.template.spec 下的 containers 添加 volumeMounts
spec.template.spec（与 containers 同级）中添加 volumes 部分
更新
访问
删除redis缓存之后在刷新一次就进来了
5.验证持久化
做了持久化之后，当删除nginx服务pod后，在重新访问，会回到之前的页面
删除mysql的pod之后，然后pod起来之后也同样回到之前的页面
redis也一样
做好持久化，就不会每次重新访问都是安装页面
删除nginx pod
5、tomcat 持久化
1.添加 pv 对应 共享目录
---
