在docker容器中安装的—docker机器（有固定ip）
1、安装步骤参考这里：https://www.jianshu.com/p/c517f09df025
2、安装过程中遇到的问题
(1) 问题1 无法启动？
[[email protected] /home] $sudo service jenkins start
Starting jenkins (via systemctl): Job for jenkins.service failed because the control process exited with error code. See “systemctl status jenkins.service” and “journalctl -xe” for details.
[FAILED]
【解决】
[[email protected] /home] $systemctl status jenkins.service
● jenkins.service - LSB: Jenkins Automation Server

经查百度：需要把当前docker容器中的java路径放到/etc/init.d/jenkins文件中
[[email protected] /home] $whereis java
java: /opt/xxxxx/install/ajdk-8.4.7-b187/bin/java
[[email protected] /home] $sudo vim /etc/init.d/jenkins
如下图，增加一行接口
[[email protected] /home] $sudo service jenkins start
Starting jenkins (via systemctl): Warning: jenkins.service changed on disk. Run ‘systemctl daemon-reload’ to reload units.
[ OK ]
再次check状态

经查百度：Caused: hudson.util.AWTProblem的解决：参考这里
从上面截取重点部分即解决方案
The problem can be mitigated by installing the full jdk. e.g.: yum -y install java-1.8.0-openjdk-devel or installing the current https://jdk8.java.net. However, the Jenkins 1.548 is using an older XStream library, which is not compatible with Java 8. If you get the following exception: http://jira.codehaus.org/browse/XSTR-746 you will have to move “back” to JDK 1.7.
[[email protected] /home] $$sudo yum -y install java-1.8.0-openjdk-devel
…
安装完成后，重新启动jenkins，同时监控日志（日志已经不报错了）
[[email protected] /home] $sudo service jenkins restart
Restarting jenkins (via systemctl): [ OK ]
日志监控—略
其他略。
