Jenkins:

Jenkins is the leader of open source CI&CD software, providing more than 1,000 plug-ins to support construction, deployment, and automation to meet the needs of any project.

CI&CD:

• Continuous integration focuses on gathering the work of various developers into a code warehouse, usually several times a day, the main purpose is to find integration errors as soon as possible, so that the team can be more closely integrated and better collaborate.
• The purpose of continuous delivery is to minimize the friction inherent in the team during the deployment or release process. Its implementation can usually automate each step of the build and deployment so that the code can be released safely at any time (ideally).
• Continuous deployment is a higher degree of automation. Whenever there are major changes to the code, it will be built/deployed automatically.

[root@jenkins ~]# yum -y install jenkins-2.222-1.1.noarch.rpm

2. Modify the configuration file

PS: The port of jenkins is 8080 by default. If it is on the same host as gitlab, you need to modify the port

[root@jenkins ~]# vim /etc/sysconfig/jenkins 
修改：
	JENKINS_USER="root"
	JENKINS_PORT="8081"  //此处环境不在同一主机上 ，则不需要修改
[root@jenkins ~]# systemctl start  jenkins
[root@jenkins ~]# systemctl enable  jenkins
jenkins.service is not a native service, redirecting to /sbin/chkconfig.Executing /sbin/chkconfig jenkins on

3. Log in to jenkins

It may take a long time here, please be patient! ! When Jenkins is ready, the browser will automatically reload.

4. Enter the password to enter the jenkinsweb page

[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword 
467c8503f0ee4e4ea592cd043e1a0847

PS: Copy the information viewed above to the administrator password box below, and then click Continue.

5. Choose to install the plugin

Here select the "X" in the upper right corner to enter the jenkinsWEB page!

6. Change jenkins web login password

Upper right corner >> admin click the drop-down triangle >> Configure >> Password field >> modify password >> save
