## 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
|
||
```

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