jenkins的安裝

1.sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo
2.sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key

3.yum install jenkins

自動安裝完成以後： 

/usr/lib/jenkins/jenkins.war    WAR包 

/etc/sysconfig/jenkins       配置文件

/var/lib/jenkins/        默認的JENKINS_HOME目錄

/var/log/jenkins/jenkins.log    Jenkins日誌文件

4.須要「vi /etc/init.d/jenkins」，把java路徑加上，以下：

# Search usable Java. We do this because various reports indicated
# that /usr/bin/java may not always point to Java >= 1.6
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html

done

5.啓動:service jenkins start
