• Layout of Devops_Project

Steps to create EC2 instances:

• Choose an Amazon Machine Image (AMI):
• we recommend the Amazon Linux 2 AMI (free-tier eligible).
  Choose an instance type: -we recommend the t2.micro (free-tier eligible).
• Security group: you have the option to configure your virtual firewall.
• Launch instance: review your instance configuration and choose "Launch".
  -Create a key pair: Select "Create a new key pair" and assign a name. The key pair file (.pem) will download automatically - save this in a safe place as we will later use this file to log in to the instance. Finally, choose "Launch Instances" to complete the set up.

• Install Jenkins in EC2 Jenkin server:

First, we’ll add the repository key to the system.

• $ wget -q -O - https://pkg.jenkins.io/debian/jenkins-ci.org.key | sudo apt-key add -
• When the key is added, the system will return OK. Next, we’ll append the Debian package repository address to the server’s sources.list:
• $ echo deb https://pkg.jenkins.io/debian-stable binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list
• $ sudo apt-get update
• $ sudo apt-get install jenkins
• Using systemctl we’ll start Jenkins:
• $ sudo systemctl start jenkins
• $ sudo systemctl status jenkins
• If everything went well, the beginning of the output should show that the service is active and configured to start at boot:
• Output

jenkins.service - LSB: Start Jenkins at boot time
Loaded: loaded (/etc/init.d/jenkins; bad; vendor preset: enabled) Active:active (exited) since Thu 2017-04-20 16:51:13 UTC; 2min 7s ago Docs: man:systemd-sysv-generator(8)

Opening the Firewall

• $ sudo ufw allow 8080
• $ sudo ufw status
• $ sudo ufw allow OpenSSH
• $ sudo ufw enable

To set up our installation, we’ll visit Jenkins on its default port, 8080, using the server domain name or IP address: http://ip_address_or_domain_name:8080

• Make new jobs

• Add the repository git

• Now Build the project,search the File pom.xml

• Build the Project

• Install Apache Tomcat in EC2 webserver

$ cat server.xml

Login webserver EC2 by SSH:

• check the port number of Tomcat webserver

• Copy IP ip_address_or_domain_name port 8090 check Tomcat server working fine.

• Add Deploy to container Plugins in Jenkins

open file

$ cat tomcat-user.xml

• check the credential of webserver passwd

Add credential of jenkins

• ADD the credential and tomcat URL:

• Build the Project, login webserver check the webapp/ dir

• ADD the cron job click in Build Triggers

• Buld the project

• Copy the ip_address_or_domain_name browsable.

• Change the code in github than again refresh the window.
  • Job automatically trigger.
  • Deployment of Webpage
