下载war包，按照官网指南执行
java -jar jenkins.war --httpPort=9090
报错，提示“fansunion” 不识别的服务。有点莫名其妙。
Linux机器名称：root@fansunion
参考了下网友资料，这个fansunion应该是 host配置。
记不清什么时候，设置的“fansunion”这个host了。
解决方法如下：
1. 查看自己服务器的host name
# hostname
2. vim etc/hosts 编辑，在下面加一行：
127.0.0.1 fansunion
3. 保存退出
4、重新执行
java -jar jenkins.war --httpPort=9090
