Docker续5：docker部署nmt（mysql，nginx，tomcat）

本文主要是介绍Docker续5：docker部署nmt（mysql，nginx，tomcat），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.前端（nginx）

[root@localhost ~]# docker pull nginx                                   //拉取nginx镜像
[root@localhost ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
nginx        latest    5ef79149e0ec   2 weeks ago   188MB
[root@localhost ~]# docker run -itd -p80:80 nginx:latest              //创建nginx容器在后台运行
[root@localhost ~]# docker exec d18c ls /usr/share/nginx/html
50x.html
index.html
[root@localhost ~]# mkdir project_exam_system
[root@localhost ~]# cd project_exam_system/
[root@localhost project_exam_system]# mkdir web
[root@localhost web]# ls                                              //上传自己的前端项目
dist
[root@localhost web]# docker run -itd -p80:80 -v /root/project_exam_system/web/dist/:/usr/share/nginx/html nginx:latest
3035a713b57eaef83c979c7a4e04416d309cc52a3e5b61933bd3e058d951152b
浏览器访问本机ip

做个hosts域名劫持,就暂时不做dns了
windows系统在这个目录下："C:\Windows\System32\drivers\etc\hosts"
添加下面这一行内容
192.168.1.80     bu.yuanyu.zhangmin

2.部署后端业务jdk

上传项目的其他部分以及jdk17
[root@localhost ~]# ls
anaconda-ks.cfg         harbor-offline-installer-v2.11.1.tgz  project_exam_system.sql
application.properties  jdk-17_linux-x64_bin.tar.gz           Project_ExamSystem-V1.0.0.war
docker.sh               project_exam_system   
[root@localhost ~]# docker pull centos                       //拉取
[root@localhost ~]# docker run -itd centos:latest                    //创建容器
aa6a96f74ed438bfe561bd9b7aed494a46bb2a189edff44573171dd2215a6738

Successfully copied 183MB to aa6a:/
[root@localhost ~]# docker cp application.properties aa6a:/         //把项目的其他部分上传到该容器中

{"code":20002,"msg":"账号不存在或密码错误"}[root@localhost ~]#                  //这样代表部署成功
[root@localhost ~]# docker commit aa6a java:v0                   //使用docker commit将容器做成镜像，至于为什么不用export和import，Docker续2中有写
sha256:46529fd5a4b2cf6affb2cd559987423a29f533c2e6d42bd3f3739dc641ac7cfa
