quartz项目一直报SchedulerException: Couldn‘t get host name!异常解决办法

服务启动报错SchedulerException: Couldn’t get host name!

项目在本地和测试环境一直可以正常启动，由于正式环境扩容了下服务器，quartz服务就一直启动异常，原因是host文件中没有配置本机名称。错误如下

org.quartz.SchedulerException: Couldn't get host name!

解决办法：

1）输入hostname命令，查看本机名称

2）编辑host文件，将本机名称添加到127.0.0.1后

vim /etc/hosts
# host文件代码
	127.0.0.1 localhost
	#添加以下代码
	127.0.0.1 ecs-xzgrq1.novalocal

再次重启服务，运行应该没有问题了
