Jenkins+git+maven+shell implementation of Project one-click Release

First, preface

As is known to all, Jenkins can implement project updates by default (via SVN, but our company uses git), and projects are released through (Maven plugin), but in this case under some containers (such as Tomcat), The JVM will report OutOfMemoryError PermGen space after several releases, because these containers will not release resources from the old Project memory permanent area after overwriting the old project, resulting in a system persistent memory overflow over time. To solve this problem, we can only resolve this issue by restarting the container after publishing. What can I do to get the container to restart automatically after the new project is released? During the restart process, we want the container to be processed after the job is safely completed (such as after the quartz job executes), the container restarts again, how to do? This article is to share with you is one of the convenient security methods.

Second, Jenkins installation and configuration

Jenkins is an open source software project designed to provide an open and easy-to-use software platform that makes continuous integration possible.

Installing the Jenkins stable version

sudo wget-o/etc/yum.repos.d/jenkins.repo Http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo

sudo rpm--import Http://pkg.jenkins-ci.org/redhat-stable/jenkins-ci.org.key

sudo yum install Jenkins

Note: This method cannot download rpm, so use the following method

rpm:https://mirror.tuna.tsinghua.edu.cn/jenkins/redhat-stable/

Upload to the specified directory

Yum Localinstall jenkins-2.7.2-1.1.noarch.rpm

Add JDK path in Jenkins config file

Vim/etc/rc.d/init.d/jenkins

/usr/local/java/jre/bin/java

Open Iptables 8080 Filter

Start Jenkins

Systemctl Start Jenkins

Visit Jenkins

http://192.168.2.64:8080/

Get Password Login

/var/lib/jenkins/secrets/initialadminpassword

Installing the MAVEN Plugin

Third, install the Git plugin

On the server where Jenkins is installed, create a pair of RSA keys and configure

Ssh-keygen-t rsa-c "Jenkins"

# All the way to the return, default path and file name, no password

CD ~/.ssh

MV Id_rsa Id_rsa_tho

MV Id_rsa.pub Id_rsa_tho.pub

Choose Add New credential, Username:git, private key Enter Directly, enter the contents of the Id_rsa_tho you just created, note that this is the private key, and that you want to copy the annotations.

Then under Gitlab Project, click on the right Configuration menu, deploy Keys, create a key with the content of the id_rsa_tho.pub you just created, name Readonly key for Jenkins, if there are multiple items that require this private Key, you can enable this key under deploy keys for each project.

So the two servers, git and Jenkins, establish a trust relationship.

Iv. Installing the Publish over SSH plugin

Installation steps:

System management → management plugin → optional plugin →artifact uploaders→publish over SSH

System settings (all advanced all expand)

Public configuration:

Passphrase: Password (Key's password if you set it up)

Path to Key:key file (private key)

Key: Copy the private key into this box

Disable exec: Disable Run command

Private configuration:

SSH Server Name: The name of the identity (whatever you take)

Hostname: Host name or IP address that requires SSH connection (recommended IP)

Username: User Name

Remote directory: Remotes

Use password authentication, or used a different key: The public configuration can be replaced (the thing that expands is public configuration is selected, this is good extensibility)

Advanced for private configuration:

Port: Ports (Default 22)

Timeout (ms): Timeout time (ms) default

Disable exec: Disable Run command

Test Configuration: Testing the connection

SCP id_rsa_tho.pub [Email Protected]:/root/.ssh/authorized_keys

This allows access between the two servers via SSH

V. Create a job

1. Source control, choose Git

2.maven Build, Build War Package

3. Select the server to publish for the specified war
