Setting up a Mercurial CGI Server
If you would like to publish your repository to the world, it must be made available via a web server. Mercurial does have a built-in web server which can be used for this, which can be accessed via hg serve. However, it will only allow one connection at a time, and it is not very robust; a broken connection at the wrong time can cause the hg serve to exit. A much better way to do things is to access Mercurial from a CGI script using an Apache web server.
If you think you may want to serve several repositories from the same server, you should check out HgWebDirStepByStep.
The following example shows you one way of making a repository named repo-name available on the host example.org.
Create a user and setup a repository
Create a user hg and setup a repository in /home/hg/repo-name:
# adduser hg # su - hg $ mkdir /home/hg/repo-name; cd /home/hg/repo-name $ hg init
You can add information to the web page about your hg repository by setting following lines in the config file repo-name/.hg/hgrc are set:
[web] description = short description of repo-name author = Example User <hg@example.com>
The repository can be remotely updated over ssh. If you want to be able to do this without explicitly typing a password each time you can create a directory /home/hg/.ssh and set up its authorized_keys file appropriately (See SharedSSH). You will be able to remotely update the repository via the command:
$ hg push ssh://hg@example.org/repo-name
Setup a cgi script to refer to your repository
Most people adding new content to the repository don't need to change the cgi script, so keeping that separate (maybe even protected by root permissions) is best. Copy the hgweb.cgi script from the mercurial sources to /var/www/cgi-hg/index.cgi and change the call to hgweb.hgweb() so that the first argument lists the path to the repository and the second argument gives the name of the repository.
Using the example names as used above, the index.cgi file might look like this:
import cgitb, os, sys
cgitb.enable()
# sys.path.insert(0, "/path/to/python/lib") # if not a system-wide install
from mercurial import hgweb
h = hgweb.hgweb("/home/hg/repo-name", "name of repository")
h.run()Make sure the index.cgi file is executable:
$ chmod a+x index.cgi
Edit your apache configuration file
Place the following in your apache configuration file and reload the apache server so that the configuration changes take effect:
Alias /hg /var/www/cgi-hg
<Directory "/var/www/cgi-hg">
DirectoryIndex index.cgi
AddHandler cgi-script .cgi
Options ExecCGI
Order allow,deny
Allow from all
</Directory>In case you also want to make the repository available as static html files (which should normally not be necessary), you could add:
Alias /hg-static /home/hg/repo-name
<Directory "/home/hg/repo-name">
Options Indexes
Order allow,deny
Allow from all
</Directory>
That's it!
Once you have populated the repository, users will be able to access the repositry using the URL: http://example.org/hg/.
Multiple repositories
You'll probably setup several repositories and not only one. The apache configuration can stay the same, but you then copy the file hgwebdir.cgi to /var/www/cgi-hg/index.cgi and for each repository the file hgweb.cgi to /var/www/cgi-hg/repo-name/index.cgi.
