症状

During Crowd installation the following error prevents you from completing the setup wizard:

診断

Make sure that the URL entered into the Base URL field is a valid URL that gets you to Crowd. If it is, and the problem persists, please proceed with the following step:

Login to the Crowd Server's OS (if it is on Linux, open a SSH session into the server), and ping the domain in the URL. Example:

$ ping example23.com

If you get no replies from the ping, proceed with the resolution below

原因

Most of the time, this is caused by the fact that the Crowd Server itself, is unable to reach Crowd at the provided URL (i.e. the URL is only reachable from external users outside of the intranet, or when a proxy is used).

In this case, the Crowd Server is unaware that the domain is actually itself, with the IP of 127.0.0.1 . It is unable to resolve that domain to the IP of 127.0.0.1

ソリューション

• Add the following to the Crowd server's /etc/hosts (Linux), or C:\Windows\system32\drivers\etc\hosts

  127.0.0.1 <domain>	

  Replace <domain> with the provided URL's domain

   

  
  例:

  127.0.0.1 example23.com

• After that, restart the entire Crowd server's OS, and try to restart the setup again.
