2.基础准备
Docker和Docker Compose已安装完成，将提供的软件包mall-swarm.tar.gz上传至master节点/root目录下并解压。
1.1.3 案例实施
1.Mariadb容器化部署
（1）编写Dockerfile
编写yum文件
[root@master ~]# cd mall-swarm
[root@master mall-swarm]# cat local.repo
[mall]
name=mall
baseurl=file:///opt/mall-repo
gpgcheck=0
enabled=1
编写初始化脚本init.sh：
[root@master mall-swarm]# cat init.sh
#!/bin/bash
mysql_install_db --user=root
mysqld_safe --user=root &
sleep 3
mysqladmin -u root password 'root'
mysql -uroot -proot -e "grant all on *.* to 'reader'@'%' identified by '123456'; flush privileges;"
mysql -uroot -proot -e "create database mall; use mall; source /opt/mall.sql;"
编写Dockerfile文件：
[root@master mall-swarm]# cat Dockerfile-mariadb
FROM centos:centos7.5.1804
MAINTAINER Guo
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY mall-repo /opt/mall-repo
COPY mall.sql /opt/
COPY init.sh /opt/
ENV LC_ALL en_US.UTF-8
RUN yum -y install mariadb-server && bash /opt/init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]
（2）构建镜像
构建镜像：
[root@master mall-swarm]# docker build -t mall-mysql:v1.0 -f Dockerfile-mariadb .
Sending build context to Docker daemon 410.3MB

2.Redis容器化部署
（1）编写Dockerfile
编写Dockerfile文件：
[root@master mall-swarm]# cat Dockerfile-redis
FROM centos:centos7.5.1804
MAINTAINER Cuo
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY mall-repo /opt/mall-repo
RUN yum -y install redis
RUN sed -i 's/127.0.0.1/0.0.0.0/g' /etc/redis.conf && \
sed -i 's/protected-mode yes/protected-mode no/g' /etc/redis.conf
EXPOSE 6379
CMD ["/usr/bin/redis-server","/etc/redis.conf"]
（2）构建镜像
构建镜像：
[root@master mall-swarm]# docker build -t mall-redis:v1.0 -f Dockerfile-redis .

/usr/lib/rabbitmq/bin/rabbitmq-server -detached
sleep 3
/usr/lib/rabbitmq/bin/rabbitmqctl add_vhost mall
/usr/lib/rabbitmq/bin/rabbitmqctl add_user mall mall
/usr/lib/rabbitmq/bin/rabbitmqctl set_user_tags mall administrator
