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

[root@master mall-swarm]# source /etc/profile

[root@master mall-swarm]# node -v

v6.17.1

[root@master mall-swarm]# npm -v

3.10.10

[root@master mall-swarm]# cd mall-admin-web

[root@master mall-admin-web]# npm run build

[root@master mall-admin-web]# mv dist/ ../
