This article mainly introduces "the method of Jenkins backup and recovery". In the daily operation, I believe that many people have doubts about the method of Jenkins backup and recovery. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "Jenkins backup and recovery method". Next, please follow the editor to study!

Preface

Jenkins is an open source tool written in Java language. The application of continuous integration and continuous delivery related technologies can improve the automation level of the software development process.

Jenkins installation from the beginning to permission settings, plug-in installation, task maintenance is a laborious project, so the importance of backing up data on a regular basis is self-evident.

In this article, we will demonstrate hand-in-hand how to back up and restore Jenkins.

Backup operation guide

Step1: create a new task

The free-style task type, Freestyle project, is recommended here.

Step2: select None for source code management

Step3: set task execution time

Select "Build Periodically", then you can set the backup time and frequency as needed

For example, 25 12 * will run the task at 12:25 every day

Add "Execute Shell" to Step4:Build module

Select Execute Shell in the Build module and add the following script content

For the convenience of readers, the content of the script is as follows:

#! / bin/bash # Jenkins Configuraitons Directory cd $JENKINS_HOME # Add general configurations, job configurations, and user content git add-- * .xml jobs/*/*.xml userContent/* ansible/* # only add user configurations if they exist if [- d users]; then user_configs= `ls users/*/ config.xml`if [- n "$user_configs"] Then git add $user_configs fi fi # mark as deleted anything that's been, well, deleted to_remove= `git status | grep "deleted" | awk'{print $3} '`if [- n "$to_remove"]; then git rm-- ignore-unmatch $to_remove fi git commit-m "Automated Jenkins commit" git push-Q-u origin master

Step5: save the above settings

Step6: initializes the local git repository

We have now added a task to back up all Jenkins data, and all backup data will be stored in the server's / var/lib/jenkins directory.

If you currently have a user name of jenkins, enter this directory and execute the following command

Cd / var/lib/jenkins & & git init

Step7: GitHub associated with the local warehouse

Git remote add origin git@github.com:username/new_repo

Step8: test whether the backup task is in effect

On the Jenkins task home page, click the Build now button. If you see the following output, the backup task has been successfully created and takes effect.

Operation guidelines for data recovery

Step1: clear the Jenkins home directory

Cd / var/lib/jenkins & & rm-rf *

Initialize the Step2:Jenkins home directory into a git repository

Cd / var/lib/jenkins & & git init

Step3: recursively clear files that are not under version control

Git clean-df

Step4: add a new remote warehouse address

Git remote add origin git@github.com:username/new_repo

Step5: backing up data from GitHub pull

Git pull origin master

Step6. Restart Jenkins with a root account

Service jenkins restart

At this point, the data has been fully restored.

At this point, the study of "the method of Jenkins backup and recovery" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
