1. Install JDK

Confirm that the JDK has not been installed before. If it is installed, make sure that the jdk is not the gcj version, otherwise Jenkins may run abnormally and you need to uninstall and reinstall the JDK;

View jdk version

# java -version

Uninstall jdk

# yum remove java

Search open-jdk

# yum search openjdk

Install open-jdk

# yum install java-1.8.0-openjdk

Check the JDK version again

[ root@localhost ~]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

2. Install GIT, skip if it is already installed#

yum install git

3. Start installing Jenkins#

Download dependency

wget -O /etc/yum.repos.d/jenkins.repo http://jenkins-ci.org/redhat/jenkins.repo

Jenkins settings backup restore, migration

You can install the ThinBackup plug-in, copy the backup folder to the new server after backup, and import it into the jenkins-ThinBackup of the new server;
Note when backing up:
If the path folder does not exist, it may cause the backup to fail, you need to create it manually, and set 755 and jenkins permissions;
Specific use can refer to:
https://blog.csdn.net/tengdazhang770960436/article/details/62043154

Install the required plug-ins: ThinBackup, Gitlab

If deployed on a LAN and deployed to a remote server, you also need to install Phing, Publish Over SSH, etc. for remote deployment;
However, it is generally not recommended to deploy locally, which is relatively troublesome. When starting the service through Java web, a fixed IP from the external network is required, and the local area network and dynamic IP cannot be realized;

Log in to the corresponding account in Gitlab, visit setting->account->copy Private token
Jenkins login configuration

Open System Management -> System Settings -> gitlab, fill in name, Gitlab host URL, use the newly copied Private token to configure a new Gitlab API token and use it, Test connection;
