II. Config and deploy the application via tomcat

Ref: 

https://www.middlewareinventory.com/blog/jenkins-tomcat-deploy-deploying-application-tomcat-using-jenkins/

Step 1: Install Tomcat in your server (CENT OS)

Reference: view here

Step 2: Tomcat Configuration

Open and config user:

<user username="tomcatmanager" password="password" roles="manager-gui"/>
<user username="deployer" password="password" roles="manager-script"/>

"Tomcatmanager" is used to manage apps in Tomcat GUI.

"deployer" is used for deploying your app via Jenkins.

Step 3: Config your GIT or SVN and Maven installed

In Jenkins GUI, Manage Jenkins > Global Tool Configuration 

Step 4: Install Deploy to Container Plugin

Manager Jenkins > Manag Plugin > Available > Deploy to Container Plugin

Step 5: Create and Configure a Maven Job with Source Code Management (Git or SVN)

New Item > Maven Project > Source code management 

Repository URL: <git_url>

Create and provide Credentials include user name/password.

You should separate many users for git. 

Step 6: Configure the Post-build action and Specify the Tomcat server details

Item > Build > Post Steps > Deploy war/ear to container.

Step 6: Build Jenkins Jobs
Item > Build Now > Check Result

Step 2. Run Agent slave in windows:

//Run default Java

$ java" -jar agent.jar -jnlpUrl http://localhost:8080/computer/Window%20Slave/jenkins-agent.jnlp -secret 234b78f48ecb**********663d38 -workDir "D:\Jenkins\app_release"

// Run Specific Java Version

$"C:\Program Files\Java\jdk-11.0.3\bin\java" -jar agent.jar -jnlpUrl http://localhost:8080/computer/Window%20Slave/jenkins-agent.jnlp -secret 234b78f48********f92383d83407663d38 -workDir "D:\Jenkins\app_release"
