=Getting Gallery2=


==How can I get Gallery2 on my webserver?==
Copy the Gallery 2 files to a directory on your webserver. There are several alternatives for this step:

* Ideally, you can use subversion to install and update your Gallery 2 installation directly on the server. But this option is only available if you have command line access to the server (ssh/telnet).
* The next best alternative is to upload the gallery2.tar.gz or gallery2.zip archive via [http://www.acronymdb.com/acronym/FTP FTP] or another method. Then unarchive / extract the archive in the command line (ssh/telnet) or with a miniature PHP script with the command '''tar -xzf gallery2.tar.gz''' for the .tar.gz archive or '''unzip gallery2.zip''' for the .zip archive. Some webhosting companies offer a control panel with a web file-browser which is capable of extracting / unarchiving archive files. It's worth a try to check if this option is available.
* If you have neither of these options, you have to upload the complete contents of the Gallery 2 archive to the webserver with an FTP program. This will take a lot of time and is error-prone. In this case, pay special attention to the '''System Checks''' step of the installer and make sure that there are no missing or modified files.

==Once I have G2, where do I begin?==
The BEST place to start is /gallery2/README.html. If you wish to jump ahead and start the install, you can point your browser at /gallery2/install/ instead. If it's your first time, you will need to visit the README.html in order to find database setup instructions.

==Does G2 have any special requirements?== 
Gallery 2 requires many of the same things that G1 required. A web server, php and some graphics manipulation programs. You probably already know these things... but there is ONE new requirement: a database. Right now, there is support for MySQL 3,4, PostgreSQL and Oracle 9/10. Of course, the other requirements are a web server (apache, iis, zeus?), php (4 or 5) and some graphics manipulation packages (netpbm, imagemagick, ffmpeg, gd). Space for the images is probably one of the more obvious requirements :)

==I can't upload images or see thumbnails in my galleries using a Fedora Core 6 host.==
The GaphicsMagick package on Fedore Core 6 on both x86 and x86_64 currently has a flaw in it where the thumbnail creation process causes a segmentation fault. There is a detailed bug logged to Fedora on this reference (BugID 237803). this FAQ will be updated once the Fedora team has evaluated and fixed this issue. This will also be tested on Fedora Core 7 and updated if appropriate.

==How can I get the latest version of Gallery2?==

You can download the latest '''official release''' of G2 from the [http://sourceforge.net/project/showfiles.php?group_id=7130&package_id=124241 sourceforge download page]. Official packages usually released not more than two times in a year, thus they might miss the latest features and improvements.<br/>
There are two ways of '''keeping current''' any time, using nightly builds or using Subversion.<br/>
[http://www.fw2.net/files/gallery Chetan Sarva], [http://jpmullan.com/galleryupdates Jesse Mullan] and [http://www.gallery2.hu Gallery2.EU] both offer nightly builds.<br/>
The instructions for using Subversion can be found [[Gallery:Gallery:Using Subversion|here]] . You can also find instructions for using TortoiseSVN [[Gallery:Gallery:Using Subversion on Windows|here]] .

To get the SVN version of Gallery, see the next FAQ item.

==Should I use nightly builds or Subversion?==
That is up to you, I would suggest Subversion if you are comfortable working with it or don't mind learning. Once you get the original source from Subversion, updating is as simple as going to your G2 directory and typing "svn update".

==Subversion uses too much disk space!==
Subversion keeps a second copy of every file so commands like "svn status" and "svn diff" can run quickly, without going over the network.  This does double the space required.. if you like the convenience of "svn update" but aren't doing development so you don't use status/diff much, then [http://subversion.tigris.org/issues/show_bug.cgi?id=525 vote for this feature] and hopefully subversion will support it someday.  For now we offer a script called [[Gallery:Gallery:Using Subversion#How do I use less disk space for a SVN checkout?|svnSlim]].

==How to upgrade Gallery2?==
See: [[Gallery:Gallery2:Upgrading|Upgrading Gallery 2]]

==How do I prevent users from accessing my site during maintenance or upgrades?==
Gallery 2.1+ has a "Maintenance mode" feature.  Edit your config.php file using a text editor and find this section.  It has instructions for turning on this mode.  Example settings (use only one of these lines):
  $gallery->setConfig('mode.maintenance', true);
  $gallery->setConfig('mode.maintenance', '/maintenance.html');
  $gallery->setConfig('mode.maintenance', '<nowiki>http://myothersite.com/</nowiki>');
Site administrators may still use the application while the site is in maintenance mode.

Typical upgrade process:
# Turn on maintenance mode;
# Put new code in place;
# Browse site as admin and make sure everything looks OK;
# Activate or configure any new modules/themes/etc you wish to use;
# Turn off maintenance mode.
