- 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
