A Fossil server can be run from most ordinary web servers as a CGI program. This feature allows Fossil to seamlessly integrate into a larger website. The self-hosting Fossil repository web site is implemented using CGI. See the How CGI Works page for background information on the CGI protocol.
To run Fossil as CGI, create a CGI script (here called "repo") in the CGI directory of your web server with content like this:
#!/usr/bin/fossil repository: /home/fossil/repo.fossil
Adjust the paths appropriately. It may be necessary to set certain
permissions on this file or to modify an
.htaccess file or make other
server-specific changes. Consult the documentation for your particular
web server. The following permissions are normally required, but,
again, may be different for a particular configuration:
The Fossil binary (
/usr/bin/fossilin the example above) must be readable/executable.
All directories leading up to the Fossil binary must be readable by the process which executes the CGI.
The CGI script must be executable for the user under which it will run, which often differs from the one running the web server. Consult your site's documentation or the web server’s system administrator.
All directories leading to the CGI script must be readable by the web server.
The repository file and the directory containing it must be writable by the same account which executes the Fossil binary. (This might differ from the user the web server normally runs under.) The directory holding the repository file(s) needs to be writable so that SQLite can write its journal files. When using another access control system, such as AppArmor or SELinux, it may be necessary to explicitly permit that account to read and write the necessary files.
Fossil must be able to create temporary files in a directory that varies by host OS. When the CGI process is operating within a chroot, ensure that this directory exists and is readable/writeable by the user who executes the Fossil binary.
Once the CGI script is set up correctly, and assuming your server is
also set correctly, you should be able to access your repository with a
URL like: http://mydomain.org/cgi-bin/repo This is assuming you
are running a web server like Apache that uses a “
for scripts like our “
To serve multiple repositories from a directory using CGI, use the "directory:" tag in the CGI script rather than "repository:". You might also want to add a "notfound:" tag to tell where to redirect if the particular repository requested by the URL is not found:
#!/usr/bin/fossil directory: /home/fossil/repos notfound: http://url-to-go-to-if-repo-not-found/
Once deployed, a URL like: http://mydomain.org/cgi-bin/repo/XYZ
will serve up the repository
/home/fossil/repos/XYZ.fossil if it
Additional options available to the CGI script are documented separately.
