+## 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
+
+ 编写Dockerfile文件
+
+```shell
+[root@xingdian zookeeper]# cat Dockerfile
+FROM centos:centos7.5.1804
+MAINTAINER Chinaskill
+ADD jdk-8u211-linux-x64.tar.gz /usr/local
+ADD apache-zookeeper-3.6.3-bin.tar.gz /usr/local/
+RUN yum -y install vim net-tools telnet tree git wget
+WORKDIR /usr/local
+ENV JAVA_HOME=/usr/local/jdk1.8.0_211
+ENV PATH=$JAVA_HOME/bin:$PATH
+ENV ZOOKEEPER_HOME=/usr/local/apache-zookeeper-3.6.3-bin
+RUN cp $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg
+EXPOSE 2181
+CMD $ZOOKEEPER_HOME/bin/zkServer.sh start-foreground
+```
+
+ 构建镜像
+
+```shell
+[root@xingdian zookeeper]# docker build -t chinaskill-zookeeper:v1.1 .
+```
+
+4.kafka镜像
+
+ 编写Dockerfile制作Kafka镜像，镜像名为chinaskill-kafka:v1.1，使用centos:centos7.9.2009基础镜像，安装Kafka服务，开放端口9092，并设置服务开机自启
+
+```shell
+[root@nfs-harbor kafka]# ls
+Dockerfile jdk-8u211-linux-x64.tar.gz kafka_2.11-2.1.0.tgz start.sh
+```
+
+ kafka下载地址：https://archive.apache.org/dist/kafka/2.1.0/kafka_2.11-2.1.0.tgz
