Start actual combat

First add in our linux maven configuration file

<!-- 阿里云仓库-->
<mirror>
  <id>alimaven</id>
  <mirrorOf>central</mirrorOf>
  <name>aliyun maven</name>
  <url>https://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

First check the mvn installation path, and then edit the setting.xml file in the conf directory

OK pre-deployment is complete, we start to configure Jenkins

Specify the port to start Jenkins, do not use 8080, or it will conflict with tomcat

java -jar /usr/lib/jenkins/jenkins.war --httpPort=8088

After the startup is complete, the browser opens Jenkins

http://ipaddress:port

note Jenkins will use processTreeKiller to kill all child processes after the build is complete, and this is the default behavior of Jenkins.
