启动时若提示下述内容，则表示启动失败

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

我们按照提示输入命令，进行失败原因查看：

systemctl status jenkins.service

输出内容：

[root@localhost jenkins]# systemctl status jenkins.service
● jenkins.service - LSB: Jenkins Automation Server

从第10行我们可以看出jenkins没有找到java文件，需要自己把java文件地址复制过去

vi /etc/init.d/jenkins

手动输入对应服务器中的java路径：

接下来我们再启动jenkins，就可以成功了。
