前言

提示：以下是本篇文章正文内容，下面案例可供参考

一、系统架构图与数据流

bash 复制代码

systemctl stop firewalld.service
setenforce 0

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo https://mirrors.aliyun.com/dockerce/linux/centos/docker-ce.repo

yum install -y docker-ce docker-ce-cli containerd.io
注意：如果是指定版本docker-ce-20.10.18
systemctl start docker.service
systemctl enable docker.service


# 1. 安装Docker（复制粘贴整条命令）
yum install -y yum-utils device-mapper-persistent-data lvm2 && yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo && yum install -y docker-ce-20.10.18 docker-ce-cli-20.10.18 containerd.io && systemctl start docker.service && systemctl enable docker.service

# 2. 验证Docker（出现版本号即为成功）
docker --version

# 3. 安装Docker Compose
华为镜像加速器

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": [
"https://0a40cefd360026b40f39c00627fa6f20.mirror.swr.myhuaweicloud.com" ]
}
EOF



sudo curl -L "https://github.com/docker/compose/releases/download/2.26.0/docker-compose-linux-x86_64" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose

# 4. 验证Docker Compose（尽量使用高版本）
docker-compose --version

安装Docker和Docker Compose

git clone RuoYi代码

bash 复制代码

mkdir /opt/ruoyi
cd /opt/ruoyi
git clone https://gitee.com/y_project/RuoYi-Vue.git

修改ruoyi配置文件

bash 复制代码

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

bash 复制代码

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

拉取node 镜像，准备前端容器环境

bash 复制代码

ocker pull node:12
① 进入ruoyi-vue目录
cd /opt/ruoyi/RuoYi-Vue
② 启动node镜像
docker run -itd --rm -v ./ruoyi-ui:/opt node:12 /bin/bash
③ 进入到此容器/opt目录下并打包前端代码
cd /opt
npm install （安装）
构建生产环境代
npm run build:prod

拉取maven镜像

bash 复制代码

##需要下载一个mvn镜像，用于为我们的后端打jar包
docker pull maven:3.6.3-openjdk-11
① 启动maven镜像
docker run -it --rm -v ./RuoYi-Vue:/vue maven:3.6.3-openjdk-11 /bin/bash
② 进入/vue目录，进行mvn命令打jar包
mvn package


退出maven容器，将/opt/ruoyi/RuoYi-Vue/ruoyi-admin/target/ruoyi-admin.jar移到/ruoyi下
mv ruoyi-admin.jar /opt/ruoyi

使用dockerfile定义后端java项目的运行环境

bash 复制代码

mkdir /opt/java
cd /opt/java
#将epel-aliyun.repo、CentOS-aliyun-lhr.repo、ruoyi-admin.jar 文件复制到当前目录
vim Dockerfile
#输入以下内容
FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
COPY epel-aliyun.repo /etc/yum.repos.d
COPY CentOS-aliyun-lhr.repo /etc/yum.repos.d
RUN yum clean all && yum makecache
run yum -y install java-1.8.0
WORKDIR /opt
COPY ./ruoyi-admin.jar /opt
CMD [ "java","-jar","ruoyi-admin.jar" ]

编写docker-compos.yml文件构建ruoyi项

在/opt/java目录下定义一个nginx.conf配置文件，内容如下：

bash 复制代码

# For more information on configuration, see:

user nginx;
worker_processes auto;

     server {
            listen 80;
            server_name localhost;
            location / {
                root /usr/share/nginx/html;
                index index.html;
            }
            location /prod-api/ {
                proxy_pass http://java.com:8080/;
            }
     }

}

bash 复制代码

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

bash 复制代码

mv ruoyi-admin/target/ruoyi-admin.jar /opt/ruoyi/

提示：这里对文章进行总结：

例如：以上就是今天要讲的内容，本文仅仅简单介绍了pandas的使用，而pandas提供了大量能使我们快速便捷地处理数据的函数和方法。

在/opt/ruoyi目录下写docker-compose.yml文件

bash 复制代码

version: '3'
services:
  ruoyi-web:
    image: nginx:1.25.3
    container_name: ruoyi-web
    hostname: ruoyi-web

查错

java和nginx未启动

将系统默认 yum 源配置文件CentOS-Base.repo复制到当前工作目录

bash 复制代码

cp /etc/yum.repos.d/CentOS-Base.repo ./
 yum -y  install java-1.8.0
