Install Jenkins on Linux

Before installation, please make sure you have installed JDK, Tomcat, Maven.

1 Import Jenkins key, install

[root@iZ94zsv4mnfZ ~]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
[root@iZ94zsv4mnfZ ~]# rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
[root@iZ94zsv4mnfZ ~]# yum install jenkins
Enter y

2 Modify the configuration

[root@iZ94zsv4mnfZ ~]# vim /etc/sysconfig/jenkins

Modify the following configuration:

#Avoid insufficient permissions when executing scripts

JENKINS_USER="root"

#The default is 8080, which conflicts with the port of tomcat. Here I am changing it to 8888. If your port 8080 is not occupied, you can leave it unchanged.

JENKINS_PORT="8888"

JENKINS_USER I have set root here and need to give access to rootjenkins的权限

[root@iZ94zsv4mnfZ ~]# chown -R root /var/log/jenkins
[root@iZ94zsv4mnfZ ~]# chgrp -R root /var/log/jenkins
[root@iZ94zsv4mnfZ ~]# chown -R root /var/lib/jenkins
[root@iZ94zsv4mnfZ ~]# chgrp -R root /var/lib/jenkins
[root@iZ94zsv4mnfZ ~]# chown -R root /var/cache/jenkins
[root@iZ94zsv4mnfZ ~]# chgrp -R root /var/cache/jenkins
