oddmuse/README.md

This is the README file distributed together with the Oddmuse script.

Installing Oddmuse on a Debian System running Apache

The following instructions require a number of tools. You can make sure they're all installed by issuing the following command as root:

apt-get install coreutils apache2 sudo wget w3m perl \
    libwww-perl libxml-rss-perl diffutils

You probably created an account for yourself. You might have to add this user to the sudo group. Here's how I created my own user as root:

adduser alex
usermod -a -G sudo alex

Now you can login as alex and do everything else using sudo.

You need to copy wiki.pl into your cgi-bin directory, and you need to make the script executable. You might also have to change its owner to an appropriate user on your system.

sudo wget -O /usr/lib/cgi-bin/wiki.pl \
  http://git.savannah.gnu.org/cgit/oddmuse.git/plain/wiki.pl
sudo chmod +x /usr/lib/cgi-bin/wiki.pl
sudo chown www-data.www-data /usr/lib/cgi-bin/wiki.pl

If you're on SUSE, the user might not be www-data but wwwrun without appropriate group:

sudo chown wwwrun.root /usr/lib/cgi-bin/wiki.pl

You should be able to test it right now! Visit http://localhost/cgi-bin/wiki.pl. If your site is available from the outside, you will be able to use a normal browser. If don't have a domain name yet, you'll probably have to use a text browser like w3m.

w3m http://localhost/cgi-bin/wiki.pl

If you create pages in this wiki, these will get stored in a temporary directory. You need change the data directory from "/tmp/oddmuse" to like "/var/local/oddmuse". The best way to do this without changing wiki.pl is by editing /etc/apache2/sites-available/default. Add the following line:

SetEnv WikiDataDir /var/local/oddmuse

Enable the default site by calling the following command:

sudo a2ensite default

Reload the Apache configuration by calling the following command:

sudo service apache2 reload

You need to create the new data directory. You webserver runs CGI scripts as www-data. Thus, you need to change the owner and group of the directory to www-data.

sudo mkdir -p /var/local/oddmuse
sudo chown www-data.www-data /var/local/oddmuse

Done! Visit your wiki and start editing. Click on the edit link (the first link below the navigation bar, at the bottom of the page). This will allow you to enter some text for this page. Click the Save button and you are done.

To add new pages, edit the homepage and add links to new pages by putting their names in [[double square brackets]].

Enjoy your wiki experience.

Checking the Apache Setup

If you think this information doesn't work for you, here are some things to check.

Apache's config directory is /etc/apache2/apache2.conf. This is where we get the www-data username from. It says:

# These need to be set in /etc/apache2/envvars
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}

Checking /etc/apache2/envvars we see the following:

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data

So that's what we're using in the chown command in our instructions above.

The default site is configured in /etc/apache2/sites-available/default. In order for it to be enabled, there must be a symlink from a file in /etc/apache2/sites-enabled to the file in sites-available. You can enable it using the following command:

sudo a2ensite default

This file also lists the directories we've used in our instructions above.

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

This means that http://localhost/cgi-bin/wiki.pl will call /usr/lib/cgi-bin/wiki.pl

Don't forget to reload the Apache configuration as shown above, or simply restart it all:

sudo service apache2 graceful

Using just Perl

You can use Mojolicious as your web server. There is a simple ##server.pl## which you can use. Here's how you might start it:

mkdir ~/oddmuse
WikiDataDir=$HOME/oddmuse perl server.pl daemon

This makes the server available on http://localhost:3000/wiki. Make sure you create the directory before starting the server! If you don't, you'll get a strange error: `STDERR: : No such file or directory at ... perl5/Mojolicious/Plugin/CGI.pm`.

If it works, feel free to upgrade to Hypnotoad.

WikiDataDir=$HOME/oddmuse hypnotoad server.pl

Note: Hypnotoad uses a different default port. The above makes the server available on http://localhost:8080/wiki. Hypnotoad will keep forking new processes. To stop it, use the -s flag.

hypnotoad -s server.pl
