在远程环境中运行grails的问题

Question

我有一个"命名"的服务器,它似乎导致Grails无法找到localhost.

Running Grails application..
2011-01-12 20:45:14,046 [main] ERROR ehcache.Cache  - Unable to set localhost. This prevents creation of a GUID. Cause was: zaftra: zaftra
java.net.UnknownHostException: zaftra: zaftra
    at java.net.InetAddress.getLocalHost(InetAddress.java:1426)

内容/etc/hosts(如图所示):

127.0.0.1       localhost localhost.localdomain zaftra
::1       localhost localhost.localdomain zaftra

Answer 1

我会假设你有一些linux风格.如果是这种情况,您可以查看您的/etc/hosts文件 - 是否有条目localhost？我希望看到类似的东西:

127.0.0.1     localhost zaftra
::1           localhost

我做了一些谷歌搜索 - 在SuperUser上有一个类似的问题 - 建议将以下内容添加到/etc/resolv.conf:

search (domainname) // in your case, search (zaftra)

您也可以尝试:

search zaftra
// or
search zaftra.example.com // if there's a more fully-qualified domain name you can use

(这是基于我在resolv.conf我的一台Ubuntu机器上输入的条目).
