Visual Editor Install

Mediawiki's Visual Editor is not included with Mediawiki. It is an external add-on that requires a LOT of work to get working.

After you have MediaWiki installed (to a users' account NOT /var/www/mediawiki and working, do the following

1. Get the Package
   1. cd extensions
   2. git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/VisualEditor.git
   3. cd VisualEditor
   4. git submodule update --init
2. Run This as Root from within the base wiki directory curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
3. Next we need to install Parsiod
   1. cd /opt
   2. yum install -y policycoreutils-python
   3. mkdir src
   4. cd src
   5. git clone https://gerrit.wikimedia.org/r/p/mediawiki/services/parsoid
   6. cp -rv parsoid /opt/
   7. cd /opt/parsoid/
   8. npm install
   9. nano config.example.yaml
   10. FIND and EDIT below:

mwApis:
# This is the only required parameter,
# the URL of you MediaWiki API endpoint.
uri: 'http://wiki.ssdcougars.tv/api.php'
# The "domain" is used for communication with Visual Editor
# and RESTBase.  It defaults to the hostname portion of
# the `uri` property below, but you can manually set it
# to an arbitrary string.
domain: 'wiki.ssdcougars.tv'  # optional
# To specify a proxy (or proxy headers) specific to this prefix
# (which overrides defaultAPIProxyURI). Alternatively, set `proxy`
# to `null` to override and force no proxying when a default proxy
# has been set.
#proxy:
#    uri: 'http://my.proxy:1234/'
#    headers:  # optional
#        'X-Forwarded-Proto': 'https'

CTL+X, Y, and rename the file to config.yaml

Next we need to add a parsoid user and group.

groupadd parsoid

useradd -g parsoid parsoid

cd /opt/

chown -Rv parsoid:parsoid parsoid

chmod -Rv u+rw,g+r,o+r parsoid

chcon -Rv --type=system_u:object_r:usr_t:s0 parsoid

Port 8000 should already be open on the hosted server, so we'll continue.

Create init.d service

cd /etc/init.d/

nano parsoid

paste the following:

#! /bin/bash
#
# parsoid start
#
# chkconfig: 345 86 14
# description: parsoid
#
### BEGIN INIT INFO
# Provides: $parsoid
### END INIT INFO
# Source function library.
. /etc/init.d/functions
rc=0
# See how we were called.
case "$1" in
start)
echo    starting parsoid
cd /opt/parsoid
/sbin/runuser parsoid -s /bin/bash -c "nohup node /opt/parsoid/bin/server.js > /dev/null 2>&1 &"
$0 status
;;
stop)
process=`ps -ef | grep 'node /opt/parsoid/bin/server.js'| grep -v grep | awk '{print $2}'`
if [ "${process}" != '' ]
then
echo    stopping parsoid
killall -9 node
fi
$0 status
;;
status)
proc_find=`ps -ef | grep 'node /opt/parsoid/bin/server.js'| grep -v grep`
if [ "${proc_find}" = '' ]
then
echo    parsoid is not running
else
echo parsoid is running: ${proc_find}
fi
;;
restart|reload)
cd "$CWD"
$0 status
$0 stop
$0 start
;;
*)
echo $"Usage: $0 {start|stop|restart|reload|status}"
exit 1
esac
exit $rc

CTRL+X, Y, Enter

chown parsoid parsoid

chmod 0755 parsoid

/etc/init.d/parsoid start

Navigate to http://wiki.ssdcougars.tv:8000 and you should see a webpage loaded with links about Parsoid.

4. Edit MediaWiki LocalSettings.js

# Add more configuration options below.
#VisualEditor
require_once "$IP/extensions/VisualEditor/VisualEditor.php";
// Enable by default for everybody

$wgDefaultUserOptions['visualeditor-enable'] = 1;

// Don't allow users to disable it

#$wgHiddenPrefs[] = 'visualeditor-enable';

$wgVirtualRestConfig['modules']['parsoid'] = array(

// URL to the Parsoid instance

// Use port 8142 if you use the Debian package

'url' => 'http://wiki.ssdcougars.tv:8000',

// Parsoid "domain", see below (optional)

'domain' => 'wiki.ssdcougars.tv',

// Parsoid "prefix", see below (optional)

'prefix' => 'localhost'

);

Now, if you did everything correctly, when you go to a Wikipage, you should see 'EDIT' AND 'EDIT SOURCE' on the page. 'EDIT' will take you to the visual editor.

If it didn't work, go through the steps again.
