wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repoCopy the code

rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.keyCopy the code

yum install jenkins Install the latest version by default, and wait a long time for installation, about 25minCopy the code

4. Check whether JDK is installed before startup

java   Display Java parameters to prove that JDK has been installedCopy the code

5. Find the Jenkins installation path

rpm -ql jenkinsCopy the code

Jenkins Installation path

/usr/lib/jenkins: the Jenkins installation directory, where the Jenkins war package will be stored. (2) /etc/sysconfig/Jenkins: Jenkins configuration file, “port”, “JENKINS_HOME”, etc can be configured here. (3) /var/lib/jenkins/ : default JENKINS_HOME. (4) the/var/log/Jenkins Jenkins. Log: Jenkins log file.

6. Configure Jenkins (1) Find Jenkins port

Vim/etc/sysconfig/Jenkins:setIgnorecase/jenkins_port enterCopy the code

Jenkins port 8080

(2) Check the usage of other ports

netstat -ntlpCopy the code

The occupied port is displayed

If the occupied port does not conflict with Jenkins port 8080, you can start Jenkins in the next step

(3) Start Jenkins

java -jar /usr/lib/jenkins/jenkins.war --httpPort=8080Copy the code

(4) Modify Jenkins port If port 8080 is not occupied by default, no modification is required. If port 8080 is occupied, modify the port to another port and open the corresponding port

Port 8899

java -jar /usr/lib/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8899Copy the code

# start

java -jar /usr/lib/jenkins/jenkins.war --httpPort=8899Copy the code

Start to finish

(5) verify Jenkins will open In hosting the browser type http://IP:Port I enter here: http://192.168.114.128:8080 (input after the modification of port: http://192.168.114.128:8899)

Enter the Jenkins decryption screen

cat /var/lib/jenkins/secrets/initialAdminPasswordCopy the code

To get the password

=> Obtain the password => Enter the password => Continue => Install the plug-in => Retry Several times. => Register the account (record the account password) => Start using Jenkins
