Install Tomcat On Linux/Unix Box & Configure with Jenkins

Step 1: Install Java

sudo apt-get update
sudo apt-get install default-jdk

Step 2: Install Tomcat

sudo apt install unzip wget
cd /tmp
wget http://mirrors.estointernet.in/apache/tomcat/tomcat-8/v8.5.47/bin/apache-tomcat-8.5.47.zip
unzip apache-tomcat-*.zip
sudo mkdir -p /opt/tomcat
sudo mv apache-tomcat-8.5.47 /opt/tomcat/

Step 3: Change Tomcat Server Port

Jenkins is running on Port 8080, and tomcat defalut port is also 8080. So we need to change the Tomcat port, I am changing it to 9090

Go to /opt/tomcat/apache-tomcat-8.5.47/conf/server.xml file

Search for Connector and change the Port Value, save the file.

Step 4: Change Permission of Scripts in /bin

cd /opt/tomcat/apache-tomcat-8.5.47/bin
ls -la
sudo chmod +x *

Step 5: Start tomcat server and accss via browser on port 9090

/opt/tomcat/apache-tomcat-8.5.47/bin/startup.sh

Step 6: Configure Jenkins with Tomcat for Auto Deployment of Artifacts.

Set Credentials of Tomcat that Jenkins use.

cd /opt/tomcat/apache-tomcat-8.5.47/conf

update tomcat-users.xml file.

roles : manager-script & admin-gui

Set password : tomcat

Step 6 : Restart the tomcat server

/opt/tomcat/apache-tomcat-8.5.47/bin/shutdown.sh
/opt/tomcat/apache-tomcat-8.5.47/bin/startup.sh
