基于Docker容器的web应用系统部署

基于docker容器的web应用系统部署

将该公司开发的基于微服务架构的web应用系统Chinaskillmall实现全容器化部署,Chinaskillmall应用系统架构图如下:

架构
模块 使用技术 备注
gpmall.sql Mysql 网站的数据库
dist目录 Nginx 网站的前端项目
gpmall-shopping web项目 8081端口,商品/购物车/首页渲染等交互
gpmall-user 8082端口,提供用户相关的交互,如登录、注册、个人中心等
user-provider 后端服务 提供用户相关服务
shopping-provider 提供购物车、推荐商品、商品等服务




环境配置【一】:容器化部署 Redis

(2)作者:Chinaskill;
(3)修改配置文件中的 bind 127.0.0.1 为 bind 0.0.0.0;
(4)设置 Redis 免密,并关闭保护模式;
(5)开放端口:6379;
(6)设置服务开机自启。
