docker部署spring boot，安装jdk17、maven3.8.8详细步骤

安装JDK和Maven

在Docker中部署Spring Boot项目需要先安装JDK和Maven。以下是详细步骤：

1.1 安装 JDK 和 Maven

js 复制代码

# 安装 JDK 17（推荐版本）
sudo yum install -y java-17-openjdk-devel

# 安装 Maven
sudo yum install -y maven

1.2 验证安装

js 复制代码

java -version
# 预期输出：openjdk version "17.0.x"

mvn -v
# 预期输出：Apache Maven 3.8.x

1.3 升级jdk到17、升级maven3.8.8

1.3.1 jdk

js 复制代码

# 卸载 OpenJDK 8
sudo yum remove -y java-1.8.0-openjdk*

# 卸载旧版 Maven
sudo yum remove -y maven

# 添加 Red Hat 官方仓库（CentOS 7）
sudo yum install -y https://cdn.azul.com/zulu/bin/zulu-repo-1.0.0-1.noarch.rpm

# 安装 Zulu JDK 17（Azure 认证版本）
sudo yum install -y zulu17-jdk

# 验证安装
java -version
# 预期输出：openjdk version "17.0.12" 2024-07-16 LTS

1.3.2 maven

js 复制代码

# 下载 Maven 3.8.8
wget https://archive.apache.org/dist/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz

# 如果上述链接失效，可直接使用阿里云镜像
wget https://mirrors.cloud.tencent.com/apache/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz

# 确保目标目录存在
sudo mkdir -p /opt

# 解压文件（注意文件名需与下载的包名一致）
sudo tar -xzf apache-maven-3.8.8-bin.tar.gz -C /opt/

# 编辑环境变量文件
echo 'export MAVEN_HOME=/opt/apache-maven-3.8.8' | sudo tee -a /etc/profile
echo 'export PATH=$MAVEN_HOME/bin:$PATH' | sudo tee -a /etc/profile

# 使配置生效
source /etc/profile

mvn -v
# 预期输出：
# Apache Maven 3.8.8 (...)
# Maven home: /opt/apache-maven-3.8.8

2.2 打包项目

js 复制代码

# 在项目根目录执行
mvn clean package

编写 Dockerfile

3.1 在项目根目录创建 Dockerfile

js 复制代码

# 使用 Eclipse Temurin JDK 17 作为基础镜像
FROM eclipse-temurin:17-jre

# 设置工作目录
WORKDIR /app

# 将 JAR 文件复制到容器中
COPY wendaoplatform-0.0.1-SNAPSHOT.jar /app/app.jar

# 暴露应用程序端口（根据您的应用需要修改）
EXPOSE 1122

# 设置容器启动时执行的命令
ENTRYPOINT ["java", "-jar", "app.jar"]

构建 Docker 镜像

js 复制代码

# 在项目根目录执行
docker build -t spring-boot-app:latest .

运行 Docker 容器

js 复制代码

# 如果之前创建了 wdzm_network，加入该网络
docker run -p 8080:8080 \
  --network wdzm_network \
  --name spring-boot-app \
  -v /root/spring-boot-app/logs:/app/logs \
  -e SPRING_PROFILES_ACTIVE=prod \
  -d spring-boot-app:latest

配置 Nginx 反向代理

js 复制代码

upstream backend {
    server spring-boot-app:1122;
    keepalive 32;  # 保持长连接
}

server {
    listen 80;
    server_name 192.168.0.64;
    root /usr/share/nginx/html/dist;
    index index.html;

    # 静态文件处理
    location / {
        try_files $uri $uri/ /index.html;
        expires 7d;  # 缓存优化
    }

    # 大文件上传路径
    location /api/upload {
        client_max_body_size 100m; 
        proxy_pass http://backend;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    # API 代理配置
    location /api/ {
        proxy_pass http://backend;  
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 60s;
        proxy_read_timeout 300s;
        proxy_send_timeout 300s;
        proxy_buffering off;
    }
}
