一、项目架构
前端、后端、数据库
1前端
静态的资源img css html js文件
jsaxios、ajax
2后端
提供数据根据web前端发送的请求从数据库中获取数据
请求都是无状态的如何保持会话
每次请求都会携带一个token字符串能够验证用户身份
3数据库
存储数据与表格
二、流程
1访问nginx服务获得页面下载静态资源
在旧的版本中都是使用浏览器直接访问java或者php服务由这些服务临时渲染一个页面文件响应给客户端。
2在浏览器中解析并且渲染页面
3向服务器发送登录请求或者其他的请求
请求的位置服务器主机ip或者域名在哪里端口是哪个服务名称映射
请求的参数账号密码
请求的方法getpost
4java服务器收到请求之后对请求解析
例如登录分发dispatch到login模块
5从数据库中查询对应的用户信息
如果用户信息的账号和密码都是正确的就返回字符串允许用户登录否则也返回异常信息字符串
三、部署
k8s中使用到的技术deployment、service、volums
1、准备nfs服务器
1新建虚拟机
2设置计划任务核对时间 [rootnginx ~]# yum -y install ntpdate[rootnginx ~]# ntpdate time2.aliyun.com26 Sep 09:45:40 ntpdate[1358]: adjust time server 203.107.6.88 offset 0.009069 sec[rootnginx ~]# which ntpdate/usr/sbin/ntpdate[rootnginx ~]# crontab -e* 5 * * * /usr/sbin/ntpdate time2.aliyun.com
3安装nfs服务应用 [rootnginx ~]# yum -y install rpcbind[rootnginx ~]# yum -y install nfs-utils
4配置文件 [rootnginx ~]# echo /root/pes *(rw,sync) /etc/exports
5准备pes资源 [rootnginx ~]# lspes
6启动nfs服务 [rootnginx ~]# systemctl start rpcbind nfs-server
7测试验证 [rootk8s-master ~]# showmount -e 10.0.0.99Export list for 10.0.0.99:/root/pes *
2、前端web实现
nginx:latest使用nfs挂载
1编写deployment清单 apiVersion: apps/v1kind: Deploymentmetadata:name: web-deploymentnamespace: defaultlabels:app: web-deploymentspec:selector:matchLabels:app: web-deploymentreplicas: 3strategy:rollingUpdate:maxSurge: 25%maxUnavailable: 25%type: RollingUpdatetemplate:metadata:labels:app: web-deploymentspec:containers:- name: nginximage: docker.io/library/nginx:latestimagePullPolicy: Neverresources:requests:cpu: 100mmemory: 100Milimits:cpu: 100mmemory: 100Miports:- containerPort: 80volumeMounts:- name: pesdistmountPath: /usr/share/nginx/htmlvolumes:- name: pesdistnfs:server: 10.0.0.99path: /root/pes/web/src/distrestartPolicy: Always
2创建deployment项目 [rootk8s-master cc]# kubectl create -f web-deployment.yaml deployment.apps/web-deployment created[rootk8s-master cc]# kubectl get podNAME READY STATUS RESTARTS AGEcluster-test-66bb44bd88-zdfdf 1/1 Running 32 (54m ago) 13dweb-deployment-7fd7479d49-6x4nn 1/1 Running 0 8sweb-deployment-7fd7479d49-bxdp9 1/1 Running 0 8sweb-deployment-7fd7479d49-xhjwb 1/1 Running 0 8s

3、后端java实现
自定义容器使用nfs挂载
1在pes目录中找到java的Dockerfile文件创建镜像 [rootnginx ~]# cd pes/java/[rootnginx java]# lsDockerfile jdk src start.sh[rootnginx java]# docker build -t java:v1 .[rootnginx java]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEjava v1 5dc6610d8a6c 18 hours ago 592MB
2镜像打包发送到两个节点 [rootnginx ~]# docker save -o java.tar java:v1[rootnginx ~]# lsjava.tar[rootnginx ~]# scp java.tar 10.0.0.77:/root[rootnginx ~]# scp java.tar 10.0.0.88:/root
3在节点中加载镜像包 [rootk8s-node01 ~]# ctr -n k8s.io images import java.tar --platformlinux/amd64[rootk8s-node01 ~]# crictl imagesIMAGE TAG IMAGE ID SIZEdocker.io/library/java v1 5dc6610d8a6cc 599MB[rootk8s-node02 ~]# ctr -n k8s.io images import java.tar --platformlinux/amd64[rootk8s-node02 ~]# crictl imagesIMAGE TAG IMAGE ID SIZEdocker.io/library/java v1 5dc6610d8a6cc 599MB
4创建资源清单 apiVersion: apps/v1kind: Deploymentmetadata:name: java-deploymentnamespace: defaultlabels:app: java-deploymentspec:selector:matchLabels:app: java-deploymentreplicas: 3strategy:rollingUpdate:maxSurge: 25%maxUnavailable: 25%type: RollingUpdatetemplate:metadata:labels:app: java-deploymentspec:containers:- name: javaimage: docker.io/library/java:v1imagePullPolicy: Neverresources:requests:cpu: 100mmemory: 100Milimits:cpu: 100mmemory: 100Miports:- containerPort: 8080volumeMounts:- name: pesjavamountPath: /java/srcvolumes:- name: pesjavanfs:server: 10.0.0.99path: /root/pes/java/srcrestartPolicy: Always

3测试验证 找不到域名设置域名 此时不能登录的原因是10.0.0.66的8080端口没有开发也没有映射到java的pod上也就是未连接后端 [rootk8s-master cc]# netstat -lntup | grep 8080
6、java-service准备
