导读一，基础部署加上ingress1.http部署mysql.yaml不变2.https部署二、k8s部署discuz要求有存储卷（hostpath）下载discuz安装包，并解压，同步到所有节点上

一，基础部署

wordpress[root@node k8s]# vim mysql.yaml
apiVersion: v1
kind: Namespace
metadata:
name: mysql
---
kind: Service
apiVersion: v1
metadata:
name: mysql
namespace: mysql
spec:
ports:
- name: http
port: 3306
targetPort: 3306
selector:
app: mysql

apiVersion: apps/v1

value: "123456"
[root@node k8s]# cat wordpress.yaml
apiVersion: v1
kind: Namespace
metadata:
name: wordpress
---
apiVersion: v1
kind: Service
metadata:
name: wordpress
namespace: wordpress
spec:
ports:
- name: http
port: 80
targetPort: 80
- name: https
port: 443
targetPort: 443
selector:
app: wordpress
type: NodePort
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: wordpress
namespace: wordpress
spec:
selector:
matchLabels:
app: wordpress
template:

labels:
app: wordpress
spec:
containers:
- name: php

[root@node k8s]# kubectl get pods -n mysql
NAME READY STATUS RESTARTS AGE
name-mysql-56f8cdb464-b2klq 1/1 Running 0 40m
[root@node k8s]# kubectl exec -it -n mysql name-mysql-56f8cdb464-b2klq -- bash
root@name-mysql-56f8cdb464-b2klq:/# mysql -uroot -p
Enter password: 123456
...
mysql> create database wordpress;
Query OK, 1 row affected (0.01 sec)
mysql> exit
[root@node k8s]# kubectl get svc -n wordpress
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
wordpress NodePort 10.104.183.253 <none> 80:30311/TCP,443:31933/TCP 30m

访问ip：30311
加上ingress1.http部署mysql.yaml不变

[root@k8s-n1 k8s]# cat wordpree.yaml
apiVersion: v1
kind: Namespace
metadata:
name: wordpress
---
apiVersion: v1
kind: Service
metadata:
name: wordpress
namespace: wordpress
spec:
ports:
- name: http
port: 80
targetPort: 80
- name: https
port: 443
targetPort: 443
selector:
app: wordpress
type: NodePort
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: wordpress
namespace: wordpress
spec:
selector:
matchLabels:
app: wordpress
template:
metadata:
labels:
app: wordpress
spec:
containers:
- name: php
image: alvinos/php:wordpress-v2
- name: nginx
image: alvinos/nginx:wordpress-v2
---
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
name: wordpress
namespace: wordpress
spec:
rules:
- host: " .wordpress.com" # 要绑定的域名
http:
paths:
- path: / # 请求的路径
pathType: Prefix #自由匹配
backend:
service:
name: wordpress # 必须和service的名字一致才可以绑定
port:
number: 80 # 服务的端口号
[root@k8s-n1 k8s]# kubectl get ingress -n wordpress
NAME CLASS HOSTS ADDRESS PORTS AGE
wordpress <none>.wordpress.com 80 8m19s
[root@k8s-n1 k8s]# kubectl get svc -n wordpress
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
wordpress NodePort 10.99.151.6 <none> 80:32379/TCP,443:32121/TCP 24m

访问域名:32379
2.https部署

# 生成证书
[root@m01 k8s]# openssl genrsa -out tls.key 2048
[root@m01 k8s]# openssl req -new -x509 -key tls.key -out tls.crt -subj /C=CN/ST=ShangHai/L=ShangHai/O=Ingress/CN= .wordpress.com
# 查看
[root@m01 k8s]# ll
-rw-r--r-- 1 root root 1289 Aug 12 22:46 tls.crt
-rw-r--r-- 1 root root 1679 Aug 12 22:46 tls.key
# 绑定证书
kubectl -n [名称空间] create secret tls [secretname] --cert=[证书.crt] --key=[证书.key]
kubectl -n wordpress create secret tls ingress-tls --cert=tls.crt --key=tls.key
---
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
name: wordpress
spec:
tls:
- secretName: ingress-tls
rules:
- host: " .wordpress.com"
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: wordpress
port:
number: 80
# 部署
kubectl apply -f
# 配置hosts访问
.wordpress.com:30542

二、k8s部署discuz
要求：

ingress ---> headless service ---> pod

1、要有健康检查
2、要求有https
3、要求有存储卷（hostpath）
1、下载discuz安装包，并解压，同步到所有节点上

[root@k8s-m-01 /opt/discuz]# for i in m2 m3;do ssh root@$i "mkdir -pv /opt/discuz" && scp discuz.tar.gz root@$i:/opt/discuz/; ssh root@$i "cd /opt/discuz && tar -xf discuz.tar.gz -C /opt/discuz && chmod -R o+w /opt/discuz/upload"; done

2、构思架构，并且编写配置清单
3、部署并调试
1、创建HTTPS证书

[root@k8s-m-01 /opt/discuz]# openssl genrsa -out tls.key 2048
Generating RSA private key, 2048 bit long modulus
.+++
.................................................................................+++
e is 65537 (0x10001)
[root@k8s-m-01 /opt/discuz]# openssl req -new -x509 -key tls.key -out tls.crt -subj /C=CN/ST=ShangHai/L=ShangHai/O=Ingress/CN= .discuz.cluster.local.com

2、部署证书

[root@k8s-m-01 /opt/discuz]# kubectl create namespace discuz
namespace/discuz created
[root@k8s-m-01 /opt/discuz]# kubectl -n discuz create secret tls discuz-secret --cert=tls.crt --key=tls.key
secret/discuz-secret created
配置清单#########################################################################################
# 1、部署MySQL集群
# 1、创建命名空间
# 2、创建service提供负载均衡
# 3、使用控制器部署MySQL实例
###
# 2、部署Discuz应用
# 1、创建命名空间
# 2、创建Service提供负载均衡（Headless Service）
# 3、创建服务并挂载代码
# 4、创建Ingress，用于域名转发(https)
###
# 3、服务之间的互连
# 1、Discuz连接MySQL ---> mysql.mysql.svc.cluster.local
