MindTouch is an enterprise wiki and collaborative portal.  For more information, see the [[Wikipedia:MindTouch Core|Wikipedia article]], and the [https://sourceforge.net/projects/dekiwiki/ SourceForge project].
Feel free to follow along on the [http://developer.mindtouch.com/en/docs/mindtouch_setup/010Installation/080Installing_from_source MindTouch Installation Guide].  However, these installation instructions assume you'll be using [[Nginx]] instead of [[Apache]].
* Install [[MySQL]].
* Install [[Nginx]] and php-fpm.
* Compile the [https://aur.archlinux.org/packages.php?ID=54501 mindtouch] [[Arch User Repository]] package and install the resulting {{ic|mindtouch}} and {{ic|mindtouch-setup}} packages.
* If you would like to use [http://www.princexml.com/ Prince] to allow PDF export, install the [https://aur.archlinux.org/packages.php?ID=13523 princexml] package from the [[Arch User Repository]].
{{Note|Although Prince is not free for commercial use, there is an [http://www.princexml.com/purchase/mindtouch explicit exception] made for MindTouch, which allows it to be used for free, even if your MindTouch installation will be used for commercial purposes.  (A note is added to the first page of every generated PDF.)  Prince can also be installed at a later date if necessary.}}
* The {{ic|mindtouch}} package added a file that can be used to simplify the nginx configuration, but you'll need to create a link to it in your nginx configuration directory. As root:
# cd /etc/nginx/conf
# ln -s /usr/share/mindtouch/nginx-rewrites mindtouch-rewrites
* Add the following configuration to nginx, modifying to suit your needs:
server {
  listen      80;
  server_name  mindtouch;
  location / {
    root /usr/share/webapps/mindtouch;
    index index.php;
    include mindtouch-rewrites;
  location ~ \.php$ {
    root          /usr/share/webapps/mindtouch;
    fastcgi_pass  unix:/var/run/php-fpm/php-fpm.sock;
    fastcgi_buffers 256 4k;
    fastcgi_buffer_size 128k;
    include      fastcgi.conf;
  location /@api/ {
    proxy_pass http://localhost:8081/;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $host:$server_port;
{{Note|The fastcgi buffer configuration is necessary, or certain MindTouch pages will cause a Bad Gateway error because the returned HTTP headers are too large for the default buffer size.}}
* Edit the {{ic|/etc/php/php.ini}} file, and ensure that the paths assigned to {{ic|open_basedir}} contain the following:
** /usr/share/webapps/
** /etc/webapps/
** /usr/bin
For instance:
open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps:/etc/webapps:/usr/bin
{{Note|{{ic|/usr/bin}} is required because MindTouch needs to run certain external tools, such as {{ic|/usr/bin/identify}} (from ImageMagick).  This is not a serious security risk, as the {{ic|http}} user is still not able to write to {{ic|/usr/bin}}.}}
* Restart Nginx and php-fpm if necessary, and open the relevant URL in your favourite web browser (e.g. http://mindtouch).
* Select "MindTouch Core", and proceed through the installation steps.  Pay special attention to specifying {{ic|localhost}} as the database host (instead of {{ic|}}).  This will ensure that the unix socket is used for communication with the database.  By default, MySQL does not enable network access.
{{Note|If you have a remote MySQL installation, enter those details here, but be aware that further configuration will be required shortly, and this has not yet been tested with this package.}}
* After clicking "Install MindTouch", you should be taken to a confirmation page indicating that your MindTouch licence was successfully generated.
* Please '''ignore''' the instructions provided in the "You're not done yet!" section.  Instead, perform the following commands, which achieve the same goal:
# mindtouch-install-config
# pacman -R mindtouch-setup
* If you have a remote MySQL server, you'll need to follow these additional steps:
** Edit the {{ic|/etc/webapps/mindtouch/mindtouch.deki.startup.xml}} file.
** Search for the {{ic|db-options}} configuration.
** Remove the {{ic|1=server=/var...}} key.
** Replace {{ic|1=Protocol=unix}} with {{ic|1=Protocol=socket}}.
* Start the MindTouch API:
# /etc/rc.d/mindtouch start
* Click "Continue to MindTouch".
==Installing or Removing Prince==
MindTouch can be configured to start using Prince if it's installed after the MindTouch installation.  It's also possible to remove Prince, in which case the PDF export option becomes unavailable in MindTouch.
* Install (or remove) the [https://aur.archlinux.org/packages.php?ID=13523 princexml] package from the [[Arch User Repository]].
* Edit the {{ic|/etc/webapps/mindtouch/mindtouch.deki.startup.xml}} file.
* Find the {{ic|princexml-path}} configuration tag.
* Set the content of the tag to be {{ic|/usr/bin/prince}}, or remove it if you want to remove Prince.
* Restart the MindTouch API.
