代码克隆	git clone https://gitee.com/y_project/RuoYi-Vue.git

系统需求

JDK >=1.8

MySQL >=5.7

Maven >=3.0

Node >=12

Redis >=3

创建ruoyi目录，以及子目录Java

克隆代码到ruoyi目录

node：

拉取node镜像

docker pull node:12.18.4

构建并打包

[root@docker ~]# cd ruoyi/
[root@docker ruoyi]# docker run -it --rm -v ./RuoYi-Vue/ruoyi-ui/:/opt node:12.18.4 /bin/bash

root@88fdc07a5500:/# cd /opt/
root@88fdc07a5500:/opt# npm install

打包完成

build下(打包出来的目录为dist)

npm run build:prod

打包完成后可以退出了，dist目录已经映射到宿主机        上

---

maven：

拉取maven镜像

docker pull maven:3.6.3-openjdk-11

修改数据库密码

 vim RuoYi-Vue/ruoyi-admin/src/main/resources/application-druid.yml 

修改redis内容

vim RuoYi-Vue/ruoyi-admin/src/main/resources/application.yml 

构建并打包(打包完成会有一个target目录)

docker run -it --rm -v /root/ruoyi/RuoYi-Vue/:/vue maven:3.6.3-openjdk-11 /bin/bash

cd /vue
mvn package

打包完成后可以退出了，target目录已经映射到宿主机

创建java目录，将target目录里的ruoyi-admin.jar拷贝到Java目录里

cp RuoYi-Vue/ruoyi-admin/target/ruoyi-admin.jar ./java/

在java目录里创建Dockerfile

Dockerfile:

拉取nginx、mysql以及redis镜像

Dockerfile代码

FROM centos:7
RUN yum -y install java-11-openjdk
WORKDIR /opt
COPY . /opt/
CMD [ "java","-jar","ruoyi-admin.jar" ]

构建镜像

docker build -t ruoyi-java:v1 .

创建docker-compose.yml

docker-compose.yml:

找一个nginx.conf文件，放在ruoyi目录下

启动

docker compose up

可能会遇到的问题：

如果报以下错误，且数据库连接没问题

后端打包有可能会很慢或者打包不成功，可能是跟maven去官网仓库找不到jar有关，解决方法是maven换国内阿里云的仓库

解决方案：

先将上个程序down掉，放在后台去启动（加个-d）

只要四个进程都在就ok了

解决乱码问题：

environment:
      - LANG=C.UTF-8
      - LC_ALL=C.UTF-8

在docker-compose.yml增加上边的代码（注意格式）

然后再将/opt/目录下的mysql-data删掉，重新弄执行docker compose up -d  就可以了
