Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.
现象：
1、首先查看日志
systemctl status jenkins.service 或 journalctl -xe
发现是找不到 java 路径
2、配置 java 路径
2.1 查看当前 java 环境位置
echo $JAVA_HOME
2.2 修改配置环境
追加 java 环境路径
vi /etc/init.d/jenkins
3、加载并重新启动
systemctl daemon-reload systemctl start jenkins
注意：如果不重新加载的话启动会告警：
4、查看状态
systemctl status jenkins
