JEECG代码中有一个Dockerfile，基本思路是以CentOS为基础镜像，在其中安装了nginx、jdk、mysql和redis，将编译出来的前端文件拷贝至nginx的指定目录，后端的jar文件放至根目录，并生成nginx的配置文件和脚本启动文件，在脚本启动文件中启动redis、nginx和java -jar的后端服务，这篇文章将MySQL和Redis拿出来，作为容器化部署的一种粗糙的解决方式。

为何不使用Alpine

大概率是因为验证码这样的东西需要sun.awt相应的支持，alpine下的OpenJDK的JRE无法支持，详细可参看：

步骤1: 启动Redis

执行命令：docker run -d --name redis -p 6379:6379 -d redis:6.0.4

liumiaocn:jeecg liumiao$ docker run -d --name redis -p 6379:6379 -d redis:6.0.4

liumiaocn:jeecg liumiao$ 

步骤2: 启动MySQL

执行命令：
docker run -d --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d liumiaocn/mysql:5.7.16

liumiaocn:jeecg liumiao$ docker run -d --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d liumiaocn/mysql:5.7.16

liumiaocn:jeecg liumiao$

步骤3: 设定MySQL

MySQL启动之后需要作如下三件事情：

• 建库
• 建表以及初始化数据
• 设定大小写不敏感

前面两件事情都有SQL文件，通过执行即可完成，大小写敏感容易被忽视，不过也很容易可以通过执行日志进行确认。事前进行如下准备，将JEECG的db下提供的如下两个SQL文件拷贝至MySQL容器之中

liumiaocn:jeecg-boot liumiao$ docker cp 1mysql_schema.sql mysql:/tmp
liumiaocn:jeecg-boot liumiao$ docker cp 2jeecgboot_mysql5.7.sql mysql:/tmp
liumiaocn:jeecg-boot liumiao$ 

建库

liumiaocn:jeecg-boot liumiao$ docker exec -it mysql sh
# ls /tmp
1mysql_schema.sql  2jeecgboot_mysql5.7.sql
# mysql -uroot -proot
mysql: [Warning] Using a password on the command line interface can be insecure.

设定大小写不敏感

mysql> exit
Bye
# echo "lower_case_table_names=1" >>/etc/mysql/mysql.conf.d/mysqld.cnf
# 

重启MySQL容器

因为大小写不敏感的设定需要重启MySQL容器才能生效，所以需要使用docker restart mysql重启MySQL容器

liumiaocn:jeecg-boot liumiao$ docker restart mysql
mysql
liumiaocn:jeecg-boot liumiao$ 

步骤4: 启动jeecg容器

本文使用基于CentOS的JEECG镜像，为了简单，此镜像将前端和后端放在了一起，所以容器中会有两个进程存在，强迫症患者可以进一步拆分，由此产生的各种设定修改请自行负责。

执行命令：docker run --name=jeecg -d -p 8080:8080 -p 8088:80 liumiaocn/jeecg:centos-2.2.0

liumiaocn:jeecg-boot liumiao$ docker run --name=jeecg -d -p 8080:8080 -p 8088:80 liumiaocn/jeecg:centos-2.2.0
16318371bb5dd33eea37f76eeabf6710dd0c0d65c43e23870d17dbde188dc655
liumiaocn:jeecg-boot liumiao$ docker ps |grep jeecg
16318371bb5d        liumiaocn/jeecg:centos-2.2.0   "/bin/sh -c '/bin/sh…"   6 seconds ago       Up 4 seconds        0.0.0.0:8080->8080/tcp, 0.0.0.0:8088->80/tcp   jeecg
liumiaocn:jeecg-boot liumiao$ 

步骤5: 确认结果

通过docker logs jeecg进行确认，如果日志中出现了如下类似结果，说明已经成功启动了：

----------------------------------------------------------Application Jeecg-Boot is running! Access URLs:Local: 		http://localhost:8080/jeecg-boot/External: 	http://172.17.0.4:8080/jeecg-boot/Swagger-UI: 		http://172.17.0.4:8080/jeecg-boot/doc.html
----------------------------------------------------------
liumiaocn:jeecg-boot liumiao$ 

登录确认页面

使用http://localhost:8088/来在本机进行登录确认

登录结果确认

注意事项

本文进行示例说明时，为了主要说明JEECG的部署方式的重点，容器启动的持久数据的保存均未列出，请根据需要自行设定。另外jar文件中由于使用了外部的Redis和MySQL服务，所以在实际使用时需要根据需要进行设定，

• 配置文件所在目录：jeecg-boot/jeecg-boot-module-system/src/main/resources
• 设定对象文件： application.yml
• 修改内容: active部分需要设定为prod

liumiaocn:resources liumiao$ head -n3 application.yml 
spring:profiles:active: prod
liumiaocn:resources liumiao$ 

• 设定对象文件： application.yml
• 修改内容: 设定相应IP

liumiaocn:resources liumiao$ grep 192.168 application-prod.yml url: jdbc:mysql://192.168.31.242:3306/jeecg-boot?characterEncoding=UTF-8&useUnicode=true&useSSL=false&tinyInt1isBit=falsehost: 192.168.31.242
liumiaocn:resources liumiao$
