主要按照文档来，下面是我按照文档按照的一个记录

#访问 https://pkg.jenkins.io/redhat-stable/

#配置可以访问jenkins仓库

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

.配置/etc/sysconfig/jenkins（需要root权限）

修改：JENKINS_USER="root"

.修改部分文件的所属组组和用户

chown -R root:root /var/log/jenkins

chown -R root:root /var/lib/jenkins

chown -R root:root /var/cache/jenkins

.检查/etc/init.d/jenkins中candidates中java的路径是否包含正确的位置

通过yum安装的软件安装到哪了？

. 通过rpm -qa | grep jenkins查找安装的具体名称

[root@jenkins jenkins]# rpm -qa | grep jenkins

jenkins-2.190.-1.1.noarch

. 通过rpm -ql 具体软件名称，查看安装明细

[root@jenkins jenkins]# rpm -ql jenkins-2.190.-1.1.noarch

/etc/init.d/jenkins

/etc/logrotate.d/jenkins

/etc/sysconfig/jenkins

/usr/lib/jenkins

/usr/lib/jenkins/jenkins.war

/usr/sbin/rcjenkins

/var/cache/jenkins

/var/lib/jenkins

/var/log/jenkins

./var/lib/jenkins就是工作空间
