自己服务器搭建jenkins执行操作的时候，没有相应的权限，解决这个问题的时候，做了一些笔记分享给大家.
1.查看jenkins默认用户
vi /etc/sysconfig/jenkins
找到JENKINS_USER发现默认用户jenkins，
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="jenkins"
修改为JENKINS_USER="root"
2.修改默认用户权限
chrow -R root:root /val/lib/jenkins
chrow -R root:root /val/cache/jenkins
chrow -R root:root /val/log/jenkins
重新启动后就可以了
service jenkins restart
还可以给jenkins用户添加相应的权限
chown -R jenkins <path>
