| | 2 | +Instructions for running WikiTrust as a remote process on another |
| | 3 | +server. |
| | 4 | + |
| | 5 | +It may be the case that you want to run WikiTrust split across |
| | 6 | +multiple servers, where the base MW instalation lives on a web server, |
| | 7 | +while the processing happens on one or more compute servers. |
| | 8 | + |
| | 9 | +MediwWiki Setup: |
| | 10 | + |
| | 11 | +Install the MW extenion as before, but instead of this line in |
| | 12 | +LocalSettings.php, |
| | 13 | + |
| | 14 | +require_once( $IP . "/extensions/Trust/Trust.php" ); |
| | 15 | + |
| | 16 | +Use this line: |
| | 17 | + |
| | 18 | +require_once( $IP . "/extensions/Trust/TrustRemote.php" ); |
| | 19 | + |
| | 20 | +Also, add this variable to LocalSettings.php: |
| | 21 | +$wgContentServerURL = "http://localhost:4444/?"; |
| | 22 | + |
| | 23 | +This specifies the server and port to query when requesting colored |
| | 24 | +markup. Note the presence of the final "?" charactor in the url. |
| | 25 | + |
| | 26 | +Next, because RemoteTrust uses the Gadgets extenion |
| | 27 | +(http://www.mediawiki.org/wiki/Extension:Gadgets), you first need to |
| | 28 | +install this extension. Gadgest allows indevedual users to turn |
| | 29 | +WikiTrust on and off. |
| | 30 | + |
| | 31 | +Lastly, add this line |
| | 32 | + |
| | 33 | +* WikiTrust|wikitrust.js |
| | 34 | + |
| | 35 | +To the page MediaWiki:Gadgets-definition. |
| | 36 | + |
| | 37 | +This installs WikiTrust as a Gadget. |
| | 38 | + |
| | 39 | +Server Setup. |
| | 40 | + |
| | 41 | +Currently remote WikiTrust is self contained. |
| | 42 | + |
| | 43 | +All that is required is the same pattern of |
| | 44 | + |
| | 45 | +$ make all |
| | 46 | +or |
| | 47 | +$ make allopt |
| | 48 | + |
| | 49 | +Launch the server process with ./analysis/server, and the processing |
| | 50 | +program with ./analysis/dispatcher. |
