修改配置文件：

candidates="

#/etc/alternatives/java

#/usr/lib/jvm/java-1.8.0/bin/java

#/usr/lib/jvm/jre-1.8.0/bin/java

#/usr/lib/jvm/java-1.7.0/bin/java

#/usr/lib/jvm/jre-1.7.0/bin/java

#/usr/bin/java

#/usr/jdk1.8

/usr/jdk1.8/bin/java

"

在candidates里插入自己的jdk java路径，其他的全部注释掉

#JENKINS_USER="jenkins"

JENKINS_USER="root"

JENKINS_USER 改成root

再次启动jenkins

[root@master ~]# /etc/init.d/jenkins start
