問題

The following error appears in the atlassian-confluence.log:

2011-03-16 18:20:03,021 ERROR [main] [net.sf.ehcache.Cache] <clinit> Unable to set localhost. This prevents creation of a GUID. Cause was: <hostname>: <hostname>
java.net.UnknownHostException: <hostname>: <hostname>
    at java.net.InetAddress.getLocalHost(InetAddress.java:1354)
    at net.sf.ehcache.Cache.<clinit>(Cache.java:145)

Or appears as an APPARENT DEADLOCK with java.net.InetAddress.getLocalHost in the stack trace:

原因

The local hostname (or COMPUTERNAME - Windows) that is running Confluence is not in the host file or is not resolvable via DNS lookup.

ソリューション

Linux:

  1.  Run hostname on the machine running Confluence
  2.  Edit/etc/hosts and add the following line:
127.0.0.1 <output of hostname>

Windows:  

  1. Open a command prompt and run ipconfig /all

  2. Locate the "Host Name" line and the hostname will be on the right

  3. Navigate to: C:\Windows\System32\drivers\etc\

  4. Edit the hosts file in a text editor of your choice as an administrator

  5. Add the following line:

127.0.0.1 <Host Name value>


(info) We strongly recommend placing the hostname in the hosts file as a fail-safe for DNS server failure.

Alternatively, make the hostname resolvable via DNS.
