若依 docker compose

准备一台服务器

本次使用虚拟机，虚拟机系统 Ubuntu20.04，内存 4G，4核。
确保虚拟机能连接互联网。

Ubuntu20.04 安装 Docker

添加 Docker 的官方 GPG key：

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

添加仓库到 apt 中：

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

  sudo apt-get update

安装最新版本的 Docker：

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

  • 1

docker-compose-plugin 就是 Docker Compose，上面的命令就安装了 Docker Compose

配置 Docker 镜像仓库：

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": ["https://mirror.baidubce.com"]
}
EOF

sudo systemctl daemon-reload

sudo systemctl restart docker

# 使用 Docker info 命令查看配置的加速仓库

启动一个 Hello World 容器测试 Docker 是否安装成功：

sudo docker run hello-world

看到如下内容就是安装成功：

使用如下命令查看 Docker 的版本以及 Docker Compose 的版本：

docker version
docker compose version

配置 Docker 命令可以使用非 Root 用户使用：

# 创建名为 docker 的用户组
sudo groupadd docker

# 将当前用户添加到 docker 用户组中
sudo usermod -aG docker $USER

# 激活
newgrp docker

# 验证非 Root 用户是否能使用 Docker 命令
docker run hello-world

sudo systemctl enable containerd.service

# 关闭 Docker 开机自启
sudo systemctl disable docker.service
sudo systemctl disable containerd.service

编写 Dockerfile 文件

# 使用官方的 OpenJDK 8 镜像作为基础镜像
FROM openjdk:8-jdk-alpine
# 创建存放上传文件的目录
RUN mkdir -p /opt/project/ruoyi/ruoyi-backend/upload-file-path
# 创建存放日志的目录
RUN mkdir -p /opt/project/ruoyi/ruoyi-backend/logs
# 安装字体文件
RUN mkdir -p /etc/apk/

RUN apk --no-cache add ttf-dejavu fontconfig
RUN set -xe && apk --no-cache add ttf-dejavu fontconfig
# 设置工作目录
WORKDIR /opt/project/ruoyi/ruoyi-backend
# 将构建好的 JAR 文件复制到容器中
COPY ./ruoyi-admin/target/ruoyi-admin.jar ruoyi-admin.jar
# 暴露应用程序端口
EXPOSE 8080
# 启动应用程序
CMD ["nohup","java","-jar","/opt/project/ruoyi/ruoyi-backend/ruoyi-admin.jar", ">", "/opt/project/ruoyi/ruoyi-backend/logs/nohup.log", "&"]

IDEA 连接虚拟机中的 Docker 并打镜像

首先，检查 IDEA 是否安装了 Docker 插件：
image.png
版本比较新的 IDEA 默认都安装了这个插件，如果没有安装，安装一下。
确保我们虚拟机上安装了 Docker 和 Docker-compose，并启动了 Docker。
找到 IDEA 下方的 Services tab 栏，按照如下操作新建一个 Docker 连接：
image.png
配置连接 Docker 的 SSH 连接：
image.png
如果按照下面通过 password 认证连接 docker，idea 会显示 “Only key-pair ssh auth type is supported for docker connectons”：
image.png

所以需要改为 key-pair 的认证方式：
image.png
点击 OK。
移除路径映射后点击 OK：
image.png
右键我们创建的 Docker 连接，点击 “connection”，就连接成功了：
image.png
找到我们的 Dockerfile，右键这个文件，点击"Modify Run Configuration"：
image.png
这里我们只需要修改 Image tag，也就是镜像名称，再点击 OK：
image.png
在打镜像前将我们的项目打包：
image.png
image.png
在 Dockerfile 文件的头部左侧的箭头位置点击 “Build image for dockerfile”，就会自动按照 Dockerfile 为我们打镜像：
image.png
打镜像完成后，就可以看到我们打的镜像了：
image.png

打 ruoyi 前端的镜像

编写 Dockerfile

在项目的根目录下创建 nginx.conf 配置文件，这个配置文件会拷贝到 ruoyi 前端镜像中，作为 Nginx 的配置文件：

user root;
worker_processes 1;

events {
    worker_connections 1024;
}

http {
    include mime.types;
    default_type application/octet-stream;
    sendfile on;
    keepalive_timeout 65;

    server {
        listen 80;
        server_name 127.0.0.1;
        charset utf-8;

        location / {
            root /opt/project/ruoyi/ruoyi-front-code;
            try_files $uri $uri/ /index.html;
            index index.html index.htm;
        }

        location /prod-api/ {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header REMOTE-HOST $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass http://ruoyi-backend-service:8080/;
        }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
            root html;
        }
    }
}

WebStorm 连接虚拟机中的 Docker 打镜像

连接和打包步骤和 IDEA 连接虚拟机 Docker 的步骤一模一样。

准备 docker compose 启动的所有容器需要的文件以及文件夹

准备 Redis 容器需要的配置文件

找到本次部署的 Redis 7.2.0 的 redis.conf 文件，编辑其中的以下内容：


# 修改连接 redis 的密码为 123456
requirepass 123456

# 注释掉 bind 127.0.0.1，bind 用于限制访问 Redis 的机器 ip,直接关掉
# bind 127.0.0.1

准备 MySQL 容器需要的初始化 SQL 文件

初始化的 SQL 文件在 Ruoyi 后端项目的如下位置：
image.png
容器首次启动的时候，我们需要执行这些初始化文件来建表、导入数据。
我们还需要一个创建数据库并创建一个用户的 sql 文件（create-database-user.sql）：

-- 创建数据库
CREATE DATABASE  `ry-vue` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
-- 创建普通用户
grant all PRIVILEGES on ry-vue.* to ruoyi@'%' identified by '123456';
flush privileges;
use ry-vue;

  • 1
  • 2
  • 3
  • 4
  • 5
  • 6

我们编写一个初始化的 sql 文件，在这个 sql 文件中再调用 create-database-user.sql、quartz.sql 和 ry_20231130.sql 这三个文件：

source /opt/mysql-service/create-database-user.sql;
use ry-vue;
source /opt/mysql-service/quartz.sql;
source /opt/mysql-service/ry_20231130.sql;

  • 1
  • 2
  • 3
  • 4

注意：这里的路径都是容器中的路径，就是容器首次启动时会调用这些命令

在宿主机中创建文件夹以及上传需要文件

/opt/project 目录的目录结构如下：

project/
└── ruoyi
    ├── docker-compose.yml -- 下面我们要编写的 docker-compose 文件
    ├── mysql-service -- 存放 mysql-service 相关文件的目录
    │   ├── other
    │   │   ├── children-sql -- 子 sql 文件存放目录
    │   │   │   ├── create-database-user.sql
    │   │   │   ├── quartz.sql
    │   │   │   └── ry_20231130.sql
    │   │   └── init -- mysql 初始化执行目录，会挂载到 docker-entrypoint-initdb.d
    │   │       └── arrange-sql.sql -- sql 编排文件，会依次调用 children-sql 文件夹中的 sql 文件
    │   └── volumes -- mysql-service 挂载的容器卷
    │       └── mysql
    └── redis-service
        └── volumes -- redis-service 挂载的容器卷
            └── redis.conf

准备 SQL 文件

quartz.sql 和 ry_20231130.sql 在 ruoyi 后端代码根目录的 sql 文件夹中就有，直接拷贝即可，但是，需要在这两个 SQL 文件的第一行添加一行使用指定数据库的 SQL 语句：

use ry-vue;

  • 1

create-database-user.sql 负责创建用户、数据库和为用户赋权：

-- 创建数据库
CREATE DATABASE  `ry-vue` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
-- 应先创建新用户
create user 'ruoyi'@'%' identified by '123456';
-- 执行授权
GRANT ALL PRIVILEGES ON `ry-vue`.* TO 'ruoyi'@'%';
-- 刷新
flush privileges;
-- 授权远程
ALTER USER 'ruoyi'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
-- 刷新
flush privileges;

source /opt/mysql-service/ry_20231130.sql;
