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

$ Sudo rpm -- import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

2. Install/check JDK:

$ Java-version

[Root @ user-api1 ~] # Java-version

Java version "1.8.0 _ 40"

Java (TM) SE Runtime Environment (build1.8.0 _ 40-b26)

Java HotSpot (TM) 64-Bit Server VM (build25.40-b25, mixed mode)

3. Install Jenkins:

$ Sudo yum install jenkins

After the installation is complete, the following directories are available:

(3.1)/usr/lib/jenkins/: jenkins installation directory, where the WAR package is located.

[Root @ user-api1 ~] # Ls-rlt/usr/lib/jenkins/

Total 64964

-Rw-r -- 1 root 66519999 Apr 2107:50 jenkins. war

(3.2)/etc/sysconfig/jenkins: The jenkins configuration file, "Port", and "JENKINS_HOME" can all be configured here.

(3.3)/var/lib/jenkins/: Default JENKINS_HOME.

$ Sudo service jenkins start

The following error may occur: "StartingJenkins-bash:/usr/bin/java: No such file or directory ". Jenkins cannot be found and java cannot be found.

In this case, you need "vi/etc/init. d/jenkins" to add the java path (as shown below ):

If no special port is configured, Use http: // <ipaddress>: 8080/to log on to Jenkins and perform related configuration (plug-in installation, permission configuration, View/Job creation, and so on ).
