Temporary failure in name resolution drm服务无法启动

公司DRM服务突然起不来，./drmserver.sh start启动的时候提示如下：
Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: drm5: drm5: Temporary failure in name resolution
sun.management.AgentConfigurationError: java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: drm5: drm5: Temporary failure in name resolution

可以看到主要提示计算机名无法解析，因为着急起服务，临时把hosts文件添加解析关系。
直接vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.10.10.10 drm5
在最后一行添加10.10.10.10 drm5 。。保存后服务已可正常启动。具体原因等后续查找，因为其他几台都未添加这个hosts。
