How to restore jenkins from aws (s3bucket)?

Step 1:- Log into server

 ssh rooot@ip

 apt-get update

apt-get install awscli

aws configure

aws s3 cp s3://jenkins-new-server/apachebackupfile name .

aws s3 cp s3://jenkins-new-server/backupfile name .

apt-get update

apt-get install apache2

apt update

apt install mysql-server

tar -xvf jenkinsbackup file name.tar

Note: If this restoration is done in new server we need to install java and jenkins,if it is old server we need to check whether we have or not

Step 2:- Install Jenkins on the server. The version of Jenkins included with the default Ubuntu packages is often behind the latest available version from the project itself. To take advantage of the latest fixes and features, you can use the project-maintained packages to install Jenkins.

Step 3:- Add the repository key to the system

 wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -

Step 4:- When the key is added, the system will return OK. Next, append the Debian package repository address to the server’s

 Sources.list:
 sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'

Step 5:- When both of these are in place, run update so that apt will use the new repository

sudo apt update

Step 6:- Finally, install Jenkins and its dependencies

 sudo apt install jenkins

Now that Jenkins and its dependencies are in place, we’ll start the Jenkins server.

Step 7:- Starting Jenkins

sudo systemctl status jenkins

Sudo systemctl start jenkins

Note: If everything went well, the beginning of the output should show that the service is active and configured to start at boot. When we start or check the status of jenkins if there is any error troubleshoot accordingly with the errors.

Step 8:- Access jenkins in browser http://ip:8080

Step 9:- Install Java 8 version

sudo apt update

sudo apt install openjdk-8-jdk openjdk-8-jre

To verify the version

java -v or java -version
