    Consider adding Mathoid installation instructions. In its current form, this instruction set utilizes the Math extension’s PNG mode. By changing $wgDefaultUserOptions['math'] to 'mathml' in LocalSettings.php, an alternate MathML mode can be used. This requires a Mathoid server for runtime equation rendering. The $wgMathFullRestbaseURL setting specifies a server in Germany that is free to use but is occasionally unresponsive, causing the wiki to either load slowly or fail to render equations. By building a local Mathoid server, responsiveness and reliability could be guarenteed. However, after much effort, Jeff has not been able to get a Mathoid installation working yet. Since MathML offers few advantages over PNG mode, getting this working is a low priority.

  6. Download and install the CAS (Single Sign-On) configuration file:

    wget -O /var/www/mediawiki/extensions/CASAuth/CASAuthSettings.php https://neurowiki-docs.readthedocs.io/en/latest/_downloads/CASAuthSettings.php

    Randomize the secret key inside the configuration file:

    sed -i '/^\$CASAuth\["PwdSecret"\]/s|=".*";|="'$(openssl rand -hex 32)'";|' /var/www/mediawiki/extensions/CASAuth/CASAuthSettings.php

    Protect the secret key:

    sudo chmod ug=rw,o= /var/www/mediawiki/extensions/CASAuth/CASAuthSettings.php*

    # An array of servers that are allowed to make use of the Single Sign Out
    # feature.  Leave to false if you do not support this feature, of if you dont
    # want to use it.  Otherwise, add servers on individual lines.

    #    $CASAuth["LogoutServers"][]='cas-logout-01.example.com';
    #    $CASAuth["LogoutServers"][]='cas-logout-02.example.com';

    # Default: $CASAuth["EmailDomain"]="example.com";
    # Restrict which users can login to the wiki?  If set to true, only the users
    # in the $CASAuth["AllowedUsers"] array can login.

    # Default: $CASAuth["RestrictRedirect"]="http://www.example.com";
    # If you dont like the uid that CAS returns (ie. it returns a number) you can

      if ($realname == " " || $realname == "" || $realname == NULL) {
        $realname = $username;
      return $realname;
  7. Modify the Parsoid configuration for the VisualEditor extension. The Parsoid server running on the virtual machine needs to communicate with the web server on the same machine. To simplify this, Parsoid is configured to connect simply to http://localhost.... For this to work, the protocol must be changed to HTTPS, and Parsoid must be permitted to ignore mismatched SSL certificates, since it will expect a certificate for “localhost”, rather than one for DynamicsHJC, NeuroWiki, or NeuroWikiDev. Make the changes by running these commands:

    sudo sed -i '/setMwApi/s|http://|https://|' /etc/mediawiki/parsoid/settings.js
    sudo sed -i '/strictSSL/s|\(\w*\)//\(.*\)|\1\2|' /etc/mediawiki/parsoid/settings.js
    sudo service parsoid restart
  8. Todo

    Update the patch for MobileFrontend. For now, skip this step during installation.

    Explain the function of NewArticleTemplate better here and in terms of the subpages actually used by students.

    Modify the NewArticleTemplate extension so that subpage templates will be used even if the parent page does not exist.

    For example, without this modification, a new page User:Foo/Bar will use the User namespace subpage template MediaWiki:NewArticleTemplate/User/Subpage if the parent page User:Foo already exists, but it will use the User namespace template MediaWiki:NewArticleTemplate/User if User:Foo does not already exist.

    This modification will force the subpage template to always be used for subpages, regardless of whether the parent page exists or not.

    Post my solution for the VisualEditor + Lockdown extension conflict to the discussion board, and then provide a “This solution is documented here” footnote in these instructions.

  14. Create database tables for the Math and ScholasticGrading extensions:

    php /var/www/mediawiki/maintenance/update.php
  15. Create aliases for URLs to the surveys and simulations using “interwiki” links. Interwiki links allow MediaWiki sites to easily create links to one another. For example, using [[wikipedia:Neuron]] on our wiki will create a link directly to the Wikipedia article on neurons. Here we use this capability to create aliases, such as [[survey:1]], that make linking to the surveys and simulations easier.

    Run the following (you will be prompted for the MySQL password twice):

    echo "INSERT INTO interwiki (iw_prefix,iw_url,iw_api,iw_wikiid,iw_local,iw_trans) VALUES ('survey','/django/survey/\$1/','','',0,0)" | mysql -u root -p wikidb
    echo "INSERT INTO interwiki (iw_prefix,iw_url,iw_api,iw_wikiid,iw_local,iw_trans) VALUES ('sim','/JSNeuroSim/simulations/\$1.html','','',0,0)" | mysql -u root -p wikidb
  16. Create a script for toggling the locked state of the wiki by downloading and installing a file:

    sudo wget -O /usr/local/sbin/lock-wiki https://neurowiki-docs.readthedocs.io/en/latest/_downloads/lock-wiki
    sudo chmod +x /usr/local/sbin/lock-wiki

    If you are curious about the contents of the script, you can view it here:


    Direct link

    # Place this script in /usr/local/sbin and make it executable (chmod +x).
    # This script will toggle the locked state of the wiki. When the wiki is locked,
    # only admins and term paper authors with a deadline extension can edit the
    # wiki.
    # Function for aborting with an error message
    die () {
        echo >&2 "$@"
        exit 1
    # Require that the user is root.
    [ "$UID" -eq 0 ] || die "Aborted: superuser privileges needed (rerun with sudo)"
    # Get the current state of the $wikiLocked variable
    STATE=$(grep ^\$wikiLocked /var/www/mediawiki/LocalSettings.php | awk '{ print $3 }')
    # Determine the new state
    if [ "$STATE" == "true;" ]; then
        echo "Wiki is now UNLOCKED. Non-admins CAN make edits."
        echo "Wiki is now LOCKED. Non-admins CANNOT make edits (unless they have a term paper deadline extension, set using Special:UserRights and listed at Special:ListUsers)."
    # Set the new state.
    sed -i '/^\$wikiLocked/s|= \(.*\);|= '$NEWSTATE'|' /var/www/mediawiki/LocalSettings.php
    exit 0
  17. At this point, individuals with CWRU accounts can log into the wiki, which will create a wiki account for them. Invite the TAs to do this now. After their accounts are created, you should visit (while logged in)


    For each TA, enter their wiki user name (which should match their CWRU user name), and add them to the following groups:

    • administrator
      • Administrators have special powers on the wiki, such as moving, deleting, or protecting pages.
    • bureaucrat
      • Bureaucrats have the ability to change group membership (using the Special:UserRights page) for any user, including administrators and other bureaucrats (making this the most powerful group).
    • grader
      • Graders can view and edit all grades on the Special:Grades page.

    Add yourself to the grader group as well (you should already be a member of the other groups).

  18. Check that all extensions are installed and working properly. Visit Special:Version and compare the list of installed extensions to the list of extensions at the beginning of this section of the instructions.

    You can test each of the essential extensions by doing the following:

    Extension Test
    CASAuthentication log in using CWRU’s Single Sign-On
    EmbedVideo try adding {{#ev:youtube|8zRtXBrmvyc||center|Survival Guide}} to a page
    ImportUsers visit Special:ImportUsers
    Lockdown remove yourself from the administrator group using Special:UserRights and try editing a policy page (restore privileges when done!)
    Math try adding <math>x=\sqrt{2}</math> to a page
    MobileFrontend click the “Mobile view” link at the bottom of any page (click “Desktop” to return to normal)
    NewArticleTemplate will test later…
    Realnames log in and look for your full name in the top right of the page
    ScholasticGrading visit Special:Grades
    UserMerge visit Special:UserMerge
    VisualEditor enable VE under Preferences > Editing, and then try editing a page by clicking “Edit” (not “Edit source”)


    Embedded videos don’t render in VisualEditor. Fix?


    When attempting to upload files through VisualEditor, it thinks I’m not logged in. Fix!

  19. Shut down the virtual machine:

    sudo shutdown -h now
  20. Using VirtualBox, take a snapshot of the current state of the virtual machine. Name it “MediaWiki extensions installed”.



This extension creates a Special page, Special:ImportUsers. After using it, run

php /var/www/mediawiki/maintenance/initSiteStats.php

to update the user count displayed on the wiki statistics page, Special:Statistics (“Active users” will change to “-1” after the script is run, but this will correct itself the next time an edit is made on the wiki).

[2]This solution is documented here.
[3]This issue is described here, and this patch (used in these instructions) was proposed for fixing it. Later, another patch was proposed, but I have not tested it since the first one works for our purposes. One or both of these patches was expected to be included in 1.27.2+, but as of July 2017 the bug is reported to still be present.
