Journal System Upgrade

From OSGeo
Jump to: navigation, search

To upgrade OJS this general process is used. I run all the backup processes as my osgeo1 user account in ~/backup/ojs.

Backup Database

Dump ojs database into a sql dump file. Takes about 5 seconds and produces a file that is only a couple megabytes.

sudo mysqldump ojs > ojs-2.2.0-pre-upgrade-2.3.mysql

Backup File System

Main files are in /var/www/ojs2. Two folders need to be backed up, the files and htdocs. Only the htdocs files will end up being updated, but they suggest backing up both.

The files folder will always be larger as all the uploaded abstracts, finals PDFs, etc. are in there - pretty important! It's about 350MB at time of writing. Creating the tgz file takes about 5 minutes and is about 315MB in size.

sudo tar -czvf ojs-2.2.0-files.tgz /var/www/ojs2/files

Next back up the htdocs folder. Several past versions of OJS are also installed, with htdocs being symlinked to the current version. Current folder is about 35MB in size. Tar process takes less than a minute and produces a 5MB file.

sudo tar -czvf ojs-2.2.0-htdocs.tgz /var/www/ojs2/htdocs

Patch / Update File System

Some info on their site is here: UPGRADE - install README

OJS versions are distributed as full distributions but also as patches between versions. Use the patch to do the upgrade when possible so that any local customisations are retained.

It's important to know what your current version is. That's why the /var/www/ojs2 folders should have the version number in the name. However, if in doubt, check the versions table in the OJS database.

In this example, the patch file used is 2.2.0 to 2.3.0 (dev version):

cd /var/www/ojs2
sudo wget http://pkp.sfu.ca/ojs/download/patch/ojs-2.2.0-0_to_2.3.patch.gz
sudo gunzip ojs-2.2.0-0_to_2.3.patch.gz

Now we'll make a copy of the current htdocs folder and apply our patches in the new folder instead. Yes, this is yet another backup copy, but worth maintaining IMHO.

sudo cp -r htdocs htdocs-2.3.0-dev
cd /var/www/ojs2/htdocs-2.3.0-dev
patch --dry-run -p1 < ../ojs-2.2.0-0_to_2.3.patch

Several prompts will ask you about patching files in the cache folder. These are temporary files that can be ignored for now - there are about 20 of them in this example that prompt you. Select the default (not to patch) by pressing enter. Always use the dry-run option to discover any issues before running it for real.

After you've confirmed you are in the right folder and the patch dry-run looks okay then run the full command by removing the --dry-run option:

sudo patch  -p1 < ../ojs-2.2.0-0_to_2.3.patch

If no errors show then you are in luck!

Change the htdocs symlink to point to the newly patched folder.

cd /var/www/ojs2
sudo rm htdocs
sudo ln -s htdocs-2.3.0-dev htdocs 

Run Upgrade Scripts

To update the database you change a setting in the OJS config.inc.php file and access the upgrade page. After the process is run from there, then you must turn the setting back off.

  • Edit config.inc.php and change installed = On to installed = Off - this allows us access to the upgrade tools in the site.

Goto the site now: http://www.osgeo.org/ojs

It will redirect you to a page with an option to upgrade. Select this option, then click the button that appears. A success page should appear.

  • Edit config.inc.php and change installed = Off back to installed = On
