## 一：环境介绍

​		应用商城Mall重新实现全容器化部署，原应用商城系统各模块功能及系统架构如下：

|       模块        | 使用技术 |                          备注                          |
| :---------------: | :------: | :----------------------------------------------------: |
|     mall.sql      |  MySQL   |                      网站的数据库                      |
|     dist目录      |  Nginx   |                     网站的前端项目                     |
|   mall-shopping   | web项目  |          8081端口，商品/购物车/首页渲染等交互          |
|     mall-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            |

## 二：项目部署

#### 1.数据库镜像

​		制作数据库MySQL镜像，镜像名为mall-mysql:v1.1，设置数据库支持UTF-8编码，设定root用户的密码为123456，并设置服务开机自启

```shell
[root@xingdian ~]# docker pull mariadb:latest
[root@xingdian ~]# docekr tag mariadb:latest chinaskill:mariadb:v1.1
```

#### 2.redis镜像

​		制作Redis镜像，镜像名为chinaskill-redis:v1.1，使用centos:centos7.9.2009基础镜像，安装Redis服务，设置Redis免密，并关闭保护模式，开放端口6379，并设置服务开机自启

```shell
[root@xingdian redis]# ls
Dockerfile  redis-4.0.4  redis-4.0.4.tar.gz  redis.conf
```

​		redis下载地址：https://download.redis.io/releases/redis-4.0.4.tar.gz

```shell
[root@xingdian redis]# wget https://download.redis.io/releases/redis-4.0.4.tar.gz
```

​		准备redis配置文件

```shell
[root@xingdian redis]# git clone https://gitee.com/xingdiancloud/redids-config.git
```

​		编写Dockerfile文件

```shell
[root@xingdian redis]# cat Dockerfile 
FROM centos:centos7.5.1804
MAINTAINER Chinaskill
RUN yum -y install gcc make
ADD redis-4.0.4.tar.gz /opt/
RUN mv /opt/redis-4.0.4 /opt/redis
WORKDIR /opt/redis
RUN make && make install
RUN rm -rf /opt/redis/redis.conf
COPY redis.conf /opt/redis
EXPOSE 6379
CMD ["redis-server","/opt/redis/redis.conf"]
```

​		构建镜像

```shell
[root@xingdian redis]# docker build -t chinaskill-redis:v1.1 .
```

#### 3.zookeeper镜像

​		编写Dockerfile制作ZooKeeper镜像，镜像名为chinaskill-zookeeper:v1.1，使用centos:7.9.2009基础镜像，安装ZooKeeper服务，开放端口2181；并设置服务开机自启

```shell
[root@xingdian zookeeper]# ls
apache-zookeeper-3.6.3-bin  Dockerfile  jdk-8u211-linux-x64.tar.gz
apache-zookeeper-3.6.3-bin.tar.gz  jdk1.8.0_211
```

​		zookeeper下载地址：https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz

```shell
[root@xingdian zookeeper]# wget https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz --no-check-certificate
```

​		JDK下载地址：https://share.weiyun.com/LHhEjTmG
