Maven 项目工程

maven打包java --jar
1.安装jdk
2.安装maven   --安装非常简单 网上教程很多，此步骤忽略--

3.配置jdk/maven环境变量

# java_jdk
export JAVA_HOME=/usr/java/jdk1.8.0_131
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin
export PATH=/usr/maven/bin/:$PATH

# java_maven
export MAVEN_HOME=/usr/maven
export PATH=${PATH}:${MAVEN_HOME}/bin

4.配置maven私服地址 阿里仓库地址

添加阿里仓库地址：

Maven 仓库默认在国外， 国内使用难免很慢，我们可以更换为阿里云的仓库。

修改 maven 根目录下的 conf 文件夹中的 settings.xml 文件，在 mirrors 节点上，添加内容如下：159行左右

<mirrors>
    <mirror>
      <id>alimaven</id>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>        
    </mirror>
</mirrors>

Jenkins上配置全局 私服：

需要安装Managed files插件

Manage jenkins -->Managed files -->Add a new Config -->Maven settings.xml

 maven工程项目中设置

5.git拉取项目代码/并进入到项目代码目录

git clone http://192.168.16.20/batar-entrance-guard/entrance-guard.git

cd entrance-guard/entrance-guard

6.进行maven编译Java项目 jar

mvn clean install -Dmaven.test.skip=true

7.后台启动程序

nohup /usr/bin/java -jar  $SERVICE_PATH/$SERVICE_NAME.jar --server.port=9921 --spring.profiles.active=dev  >>/dev/null 2>&1 & 

Jenkins结合shell自动部署：

构建一个maven工程任务

 

 

 

 

 

shell脚本案例：

case $Status in
  Deploy)
    {
    echo "Status:$Status"
    echo "Version:$BUILD_NUMBER"
    SERVICE_NAME="entrance-guard-manage"
    SERVICE_PATH="/project/batar-entrance-guard/entrance-guard"
    SERVICE_BACKUP="/backup/batar-entrance-guard/entrance-guard"
    BUILD_ID=DONTKILLME
     
    PIDS=`ps -ef |grep java | grep 9921 | awk '{print $2}'`
    if [ "$PIDS" != "" ];then
    /usr/bin/kill -9 $PIDS
    fi
    cd $SERVICE_PATH
    cp -rf  $WORKSPACE/entrance-guard/entrance-guard-manage/target/$SERVICE_NAME.jar  $SERVICE_PATH
    nohup /usr/bin/java -jar  $SERVICE_PATH/$SERVICE_NAME.jar --server.port=9921 --spring.profiles.active=dev  >>/dev/null 2>&1 & 

    #备份
    mv  $WORKSPACE/entrance-guard/entrance-guard-manage/target/$SERVICE_NAME.jar  $SERVICE_BACKUP/$BUILD_NUMBER.jar
    }
    ;;
  Rollback)
    {
    echo "Status:$Status"
    echo "Version:$Version"
    SERVICE_NAME="entrance-guard-manage"
    SERVICE_PATH="/project/batar-entrance-guard/entrance-guard"
    SERVICE_BACKUP="/backup/batar-entrance-guard/entrance-guard"
    BUILD_ID=DONTKILLME
     
    rm -rf  $SERVICE_PATH/$SERVICE_NAME.jar
    cp $SERVICE_BACKUP/$Version.jar  $SERVICE_PATH/$SERVICE_NAME.jar  
    
    PIDS=`ps -ef |grep java | grep 9921 | awk '{print $2}'`
    if [ "$PIDS" != "" ];then
    /usr/bin/kill -9 $PIDS
    fi
    cd $SERVICE_BACKUP
    nohup /usr/bin/java -jar $SERVICE_PATH/$SERVICE_NAME.jar --server.port=9921 --spring.profiles.active=dev>>/dev/null 2>&1 & 

    }
