springboot+gradle+docker+nginx项目部署到ubuntu云服务器.md

安装gradle

• 下载，解压到指定目录

  wget https://downloads.gradle-dn.com/distributions/gradle-7.4-bin.zip
   unzip -d /opt/gradle gradle-7.4-bin.zip
   #查看是否解压成功
   ls /opt/gradle/gradle-7.6

• 配置环境变量

  sudo vim /etc/profile.d/gradle.sh
  sudo chmod +x /etc/profile.d/gradle.sh
  source /etc/profile.d/gradle.sh

  gradle.sh文件内容

  export GRADLE_HOME=/opt/gradle/gradle-7.4
  export PATH=${GRADLE_HOME}/bin:${PATH}

• 验证安装

  gradle -v

构建jar包

• 配置文件-build.gradle 文件

  plugins {
      id 'org.springframework.boot' version '2.6.11'
      id 'io.spring.dependency-management' version '1.0.13.RELEASE'
      id 'java'
  }
  
  jar {
      enabled = true
  }
  
  bootJar {
  
      archivesBaseName = 'boss-server' // jar包名
      manifest {
          attributes "Manifest-Version": 1.0,
                  'Start-Class': 'com.lcf.BlueApplication' //  springboot项目的启动类
      }
  
  }
  
  group = 'com.boss'
  //version = '1.0.0'
  sourceCompatibility = '1.8'
  
  repositories {
      mavenCentral()
  }
  
  
  
  dependencies {
      implementation 'org.springframework.boot:spring-boot-starter'

  }
  
  test {
      useJUnitPlatform()
  }

• jar包构建命令

  gradle bootJar

构建容器镜像

• 创建Dockerfile 文件

  vi Dockerfile

• 修改 Dockerfile 文件并保存，将jar包复制到当前目录

  # 拉取一个jdk为1.8的docker镜像
  FROM java:8
  # 声明作者是lcf
  MAINTAINER lcf
  # 前一个 ROOT.jar 为上传的jar包，后一个 ROOT.jar 是将服务器中jar包对应在容器中运行的jar包名称
  ADD ROOT.jar ROOT.jar
  # 容器暴露的端口号，需要与jar包在容器中运行使用端口号一致
  EXPOSE 8080
  # 容器启动之后执行的命令， java -jar ROOT.jar
  ENTRYPOINT ["java","-jar","ROOT.jar"]

• 执行命令，构建镜像, . 表示Dockerfile在当前目录

  docker build -t boss-server .

• 构建容器

  # --restart=always 表示docker容器在停止或服务器开机之后会自动重新启动
  docker run -d --restart=always --name demo -p 8080:8080 -v /docker/logs/test:/logs boss-server

• 验证是否成功

  docker ps

nginx 配置反向代理

问题：转发后多了一个反斜杠

解决：使用正则替换前缀

location /pager-server {
                rewrite  ^/pager-server/?(.*)$ /$1 break;
                proxy_pass http://localhost:8080/ ;
                proxy_redirect default;
            }
