Jenkins自动化部署-配置项目（下）

一、新建项目，设置Git地址，账号密码。

多种方式，ssh方式，需要配置私钥。

第1个错误：Git没安装

Linux机器上，先安装Git软件。 CentOs系统，yum install git

git -version 检查是否安装成功

解决之后，再次构建之后，产生了项目目录。

cd /root/.jenkins/workspace/test-auto-deploy

第2个错误：权限不对，说明git clone，http访问的账号密码没有设置正确。

The requested URL returned error: 401 Unauthorized while accessing

生成公钥-私钥对

ssh-keygen -t rsa -C [email protected] 密钥目录，不输入，使用默认目录。 密码不输入，为空，直接登录。

Gitee项目，增加公钥

部署公钥管理-添加公钥

Git仓库地址:[email protected]:xxx/techplatform.git (有网友用的是 git://开头，git代码托管在gitee，难道是这个不太一样)

配置Credentials：Username with password 账号：[email protected] 密码：123456

二、Jenkins首次控制台输出

Skipping changelog. Triggering test-auto-deploy » default test-auto-deploy » default completed with result SUCCESS Finished: SUCCESS

说明Git clone代码成功了。

三、配置Maven

下载Maven http://maven.apache.org/download.cgi

解压，配置环境变量

vim /etc/profile export MAVEN_HOME=/home/soft/apache-maven-3.6.1 export MAVEN_HOME export PATH=$PATH:$MAVEN_HOME/bin

mvn -version

Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T03:00:29+08:00) Maven home: /home/soft/apache-maven-3.6.1 Java version: 1.8.0_181, vendor: Oracle Corporation, runtime: /home/soft/jdk1.8/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "2.6.32-696.3.2.el6.i686", arch: "i386", family: "unix"

安装Maven集成插件(Maven Integration)

重启Jenkins

http://47.15.99.4:9090/restart

新建项目，多了1个选项"构建一个maven项目"

构建一个maven项目.Jenkins利用你的POM文件,这样可以大大减轻构建配置.

配置Maven

构建-增加构建步骤-调用顶层Maven目标 配置如下： clean install -U -Dmaven.test.skip=true

执行构建,找不到mvn

[default] $ mvn -f pom.xml clean install -U -Dmaven.test.skip=true FATAL: command execution failed java.io.IOException: error=2, No such file or directory at java.lang.UNIXProcess.forkAndExec(Native Method) at java.lang.UNIXProcess.(UNIXProcess.java:247) at java.lang.ProcessImpl.start(ProcessImpl.java:134) at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029) Caused: java.io.IOException: Cannot run program "mvn" (in directory "/root/.jenkins/workspace/jtn-techplatform/default"): error=2, No such file or directory at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)

系统管理-全局工具配置-Maven

Name: maven MAVEN_HOME:/home/soft/apache-maven-3.6.1

JDK配置

别名： JDK1.8 JAVA_HOME : /home/soft/jdk1.8

项目的配置Maven选择指定的名字“maven”，而不是默认

目标： clean install -U -Dmaven.test.skip=true

四、配置Shell脚本

自动化部署3步走，Git Clone代码，Maven打包，执行Jar包。

将应用停止，Copy jar到指定目录，增加权限，再执行jar

Shell脚本 echo "Stopping SpringBoot Application jtn-techplatform-impl.jar" pid=ps -ef | grep jtn-techplatform-impl.jar | grep -v grep | awk '{print $2}' if [ -n "$pid" ] then kill -9 $pid fi cp -f /root/.jenkins/workspace/jtn-techplatform/default/techplatform-impl/target/jtn-techplatform-impl.jar /home/app/jtn-techplatform-impl.jar cd /home/app chmod 777 /home/app/jtn-techplatform-impl.jar nohup java -jar jtn-techplatform-impl.jar >techplatform.log 2>&1 &

最难的提示：获取进程id grep -v grep，排除grep本身的简称

grep -v 可以实现 NOT 操作。 -v 选项用来实现反选匹配的（ invert match）。如，可匹配得到除下指定pattern外的所有lines。 参考资料：https://www.jianshu.com/p/4ec50fdaf388

www 3142 2491 99 16:36 pts/0 00:01:15 java -jar system-release-1.0.0.jar awk '{print $2}' 获得第2个参数，3142就是想要的线程数/进程数

五、最后1个问题

nohup命令执行之后，Linux机器上并没有发现java应用正常运行。 在Jenkins里配置的是“nohup java -jar jtn-techplatform-impl.jar >techplatform.log 2>&1 &” 但是Jenkins控制台显示的是 “+ nohup java -jar jtn-techplatform-impl.jar”

一直以为是最后一个“&”没有让他在后台运行，发现怎么改都不行。 只好搜索“Jenkins nohup”，找到一篇文章：

背景

jenkins持续集成，需要任务后台执行（nohup执行）结果发现jenkins的job执行完后，看不到运行的进程

步骤

原因就是这么一个情况：Jenkins任务结束时候自动关掉了所有的子进程

不过可以设置一些东西让其可以在后台运行

其实就是在脚本中加入一句BUILD_ID=DONTKILLME

问题的根本在于是Jenkins使用processTreeKiller杀掉了所有子进程，而且这是Jenkins的默认行为。 其实回头来看这个问题，就发现Jenkins的做法非常合理。当一次build异常结束，或被人终止时， 必然需要结束所有这次build启动的子进程。下面的link提供了更多细节，以及解决方法。 https://wiki.jenkins-ci.org/display/JENKINS/ProcessTreeKiller

六、SpringBoot项目打包的3个小问题

犯了一个错误，Java资源文件目录在代码中写成了src/main/resource，应该用“复数s”。 src/main/resources/${deploy.type}src/main/resources dev/ test/ pro/*

SpringBoot项目打包用这个，pom.xml的Packaging需要配置成jar，不是pom，也不是war。 org.springframework.boot spring-boot-maven-plugin 1.4.2.RELEASE com.jiutianniao.techplatform.JtnTechPlatformApplication repackage

最后，核心jar包，引入third.jar，想扫描里面的mapper等resource资源。 //classpath private static final String CLASSPATH_MAPPER_XML = "classpath:/mapper/jtn/*.xml";

七、一些关键的截图

源码管理Git配置

Maven命令

执行Shell

echo "Stopping SpringBoot Application jtn-techplatform-impl.jar"
pid=`ps -ef | grep jtn-techplatform-impl.jar | grep -v grep | awk '{print $2}'`
if [ -n "$pid" ]
then
   kill -9 $pid
fi
cp -f /root/.jenkins/workspace/jtn-techplatform/default/techplatform-impl/target/jtn-techplatform-impl.jar /home/app/jtn-techplatform-impl.jar
cd /home/app
chmod 777 /home/app/jtn-techplatform-impl.jar
BUILD_ID=DONTKILLME

nohup java -jar jtn-techplatform-impl.jar >techplatform.log 2>&1 &

其它配置
