Recently I had configured subversion edge in my Linux machine. Installation was keen (installed as such described in this link [http://www.collab.net/lightbox/download_info/61/34]) and I was able to log in to the csvn console, access and create subversion repositories.

After restarting the machine I was able to log in to csvn console only and in the status page it was saying subversion server is down. When I clicked the start button an error was displayed saying "There was a problem starting the Subversion server!" . When I checked the server error logs I got console.log as :

I googled and found many of them say it's because of user permission, ownership etc. I had gone through all of the steps and it wasn't a successful attempt. Here I expect a reliable solution. please provide me a solution for this.

The Apache process is refusing to start because /opt/csvn/data/conf/csvn_main_httpd.conf has configuration on line 16 to have the web server start as root. That's not a good thing; the error message is making it clear that it won't start with this configuration.

From the application's readme, it sounds like it tries to start under the user who runs the start command;

5. Start the server.  Be sure that you are logged in as your own userid and not running as root.

..maybe it's also populating the csvn_main_httpd.conf file with the running user's information? Try starting it under a different user.

Alternately, I'd recommend just using Apache + mod_dav_svn for serving your SVN repositories.. something about having a jetty service starting the Apache service seems needlessly complicated.

a simple way to overcome this situation is, don't install the subversion edge, do only start the server. when its installed there might be having a chance of changing UID of files. –  user145862 Feb 1 '13 at 7:38

a simple way to overcome this situation is, don't install the subversion edge, do only start the server using /csvn/bin/csvn start. this error happens , in most cases, during installing csvn using root account. this will change UID of conf files somehow.
