一、运行Jenkins部署任务

• 1. 执行Jenkins部署任务
• 2. 打开浏览器访问部署应用程序
• 3. 确定发布结果的正确性
• 4. 确认执行结果成功

• 1. 执行Jenkins部署任务
  
• 查看控制台输出
  
  异常信息如下：

• 2. 打开浏览器访问部署应用程序
  • 浏览器访问：http://192.168.45.145:8090/
    
    现在成功部署成功了！！！！
• 3. 确定发布结果的正确性
• 4. 确认执行结果成功

本章回顾

本章讲述了

• 典型的自动化部署任务过程
• 并实际创建了一个Jenkins自动化部署任务开发中的一些要素
• 实际执行自动化部署任务
  通过这个任务，我们可以看到测试环境被自动化的创建了出来。有了这个任务我么尝试一下，实战环节。
  在实战中我们实际体验一下如何达到开发修改代码，推送远程github仓库，测试一键部署测试环境
  
• 附上：deploy.sh脚本内容：

#!/usr/bin/env bash
#编译+部署order站点

#需要配置如下参数
# 项目路径, 在Execute Shell中配置项目路径, pwd 就可以获得该项目路径
# export PROJ_PATH=这个jenkins任务在部署机器上的路径

# 输入你的环境上tomcat的全路径
# export TOMCAT_APP_PATH=tomcat在部署机器上的路径

### base 函数
killTomcat()
{
    pid=`ps -ef|grep tomcat|grep java|awk '{print $2}'`
    echo "tomcat Id list :$pid"
    if [ "$pid" = "" ]
    then
      echo "no tomcat pid alive"
    else
      kill -9 $pid
    fi
}
cd $PROJ_PATH/order
mvn clean install

# 停tomcat
killTomcat

# 删除原有工程
rm -rf $TOMCAT_APP_PATH/webapps/ROOT
rm -f $TOMCAT_APP_PATH/webapps/ROOT.war
rm -f $TOMCAT_APP_PATH/webapps/order.war

# 复制新的工程
cp $PROJ_PATH/order/target/order.war $TOMCAT_APP_PATH/webapps/

cd $TOMCAT_APP_PATH/webapps/
mv order.war ROOT.war

# 启动Tomcat
cd $TOMCAT_APP_PATH/
sh bin/startup.sh
