Gallery

Install

On sql vserver

mysqladmin -uroot -p create gallery2
mysql gallery2 -uroot -p -e"GRANT ALL ON gallery2.* TO admin_gallery2@public.teuwen.org IDENTIFIED BY 'gal_long_pwd'"

On public vserver

apt-get install gallery2
   sql host: sql.teuwen.org
   admin user to create dbs: admin_gallery2 / gal_long_pwd

/etc/gallery2/apache.conf: uncomment first line alias /gallery2 OR create vhosts as suggested in the last lines but don't do both at the same time.

If you use virtual hosts

mv /etc/apache2/conf.d/gallery2 /etc/apache2/sites-available/
ln -s /etc/apache2/sites-available/gallery2 /etc/apache2/sites-enabled

Otherwise this gallery virtualhost will be the one by default

apt-get install locales

activate locales you want for gallery, in their ISO form, not UTF8

apt-get install dcraw jhead zip unzip libjpeg-progs php4-gd ffmpeg imagemagick
/etc/init.d/apache2 reload

Be sure both hosts know each other via e.g. /etc/hosts

create /usr/share/gallery2/.htaccess with

php_value memory_limit 64M

Prepare directory for the albums

mkdir /home/gallery2
chown www-data:www-data /home/gallery2

Go to public.teuwen.org/gallery2
Choose Mysql with transactions and give the credentials

Gallery migration

Once you have migrated your Gallery1 to Gallery2 with the migration module

Enable URL Redirection under Apache webserver:

Ensure the mod_rewrite Apache module is enabled:
a2enmod rewrite
/etc/init.d/apache2 force-reload

• Enable the module URL Rewrite in Gallery2
• URL Rewrite administration -> Rules -> Migration -> activate
• If you have troubles with url rewrite, especially if you touched the directory structure or established vhosts, deinstall completely the URL Rewrite module and reinstall it.

PG Theme

• http://pedrogilberto.net/pgtheme/
• http://gallery.menalto.com/node/33603
• http://gallery.menalto.com/gallery/screenshots/screenshotsG2/themes/pg/
• ! save /usr/share/gallery2/modules/slideshow/templates/local/Slideshow.tpl

Jpegtran

Gallery1 used to use jpegtran to rotate automatically imported images in a lossless fashion.
Gallery2 doesn't :-(

You can install the module jpegtran for Gallery2

• Uncompress it in /usr/share/gallery2/modules
• Install it and activate it under the administration view of Gallery2
• Install jpegtran (libjpeg-progs under Debian)
• Test it under the administration view of Gallery2, there is a new jpegtran shortcut in the graph tools menu

Now this module does not automates anything when importing images but at least when you rotate manually a picture, it'll use jpegtran instead of the fat slow lossy ImageMagick rotation.

For rotations when importing, I do it with gthumb:

• select all images (including those already with the correct orientation, don't bother selectiong only those to be rotated ;-) )
• Tools -> Rotate Images -> + Adjust photo orientation + Apply to all images -> Apply

Piwik

cf http://codex.gallery2.org/Gallery2:How_To_Add_Google_Analytics_to_my_Gallery_2

Create directory /usr/share/gallery2/themes/<mytheme>/templates/local
Copy /usr/share/gallery2/themes/<mytheme>/templates/theme.tpl to /usr/share/gallery2/themes/<mytheme>/templates/local/theme.tpl, edit that copy and add just above the </body> tag the Piwik javascript

You can also clear the template cache, cf http://codex.gallery2.org/Gallery2:Editing_Templates#What_if_I_don.27t_see_my_changes

Gallery2 error on missing plugins

I don't know exactly when but with v2.3.1.dfsg-1 (debian), gallery2 failed to add new pictures with an error about a missing file uploadapplet/ItemAddUploadApplet.inc
Even by launching manually the /upgrade once again it wasn't working still.
I had to edit manually the DB to remove references to that plugin and another one also linked to the Gallery Remote:

DELETE FROM `gallery2`.`g2_FactoryMap` WHERE `g2_FactoryMap`.`g_classType` = 'ItemAddPlugin' AND `g2_FactoryMap`.`g_className` = 'ItemAddUploadApplet' AND `g2_FactoryMap`.`g_implId` = 'ItemAddUploadApplet' AND `g2_FactoryMap`.`g_implPath` = 'modules/uploadapplet/ItemAddUploadApplet.inc' AND `g2_FactoryMap`.`g_implModuleId` = 'uploadapplet' AND `g2_FactoryMap`.`g_hints` = 'N;' AND `g2_FactoryMap`.`g_orderWeight` = '5' LIMIT 1
DELETE FROM `gallery2`.`g2_FactoryMap` WHERE `g2_FactoryMap`.`g_classType` = 'ItemAddPlugin' AND `g2_FactoryMap`.`g_className` = 'ItemAddGalleryRemote' AND `g2_FactoryMap`.`g_implId` = 'ItemAddGalleryRemote' AND `g2_FactoryMap`.`g_implPath` = 'modules/remote/ItemAddGalleryRemote.inc' AND `g2_FactoryMap`.`g_implModuleId` = 'remote' AND `g2_FactoryMap`.`g_hints` = 'N;' AND `g2_FactoryMap`.`g_orderWeight` = '5' LIMIT 1

Then in the Administration interface, go to Maintenance and clean the DB cache.
