Upgrading a CKAN 2 package install to a new minor release¶
Before upgrading CKAN you should check the compatibility of any custom themes or extensions you’re using, check the changelog, and backup your database. See Upgrading CKAN.
Each minor release is distributed in its own package, so for example CKAN 2.0.X and 2.1.X will be installed using the python-ckan_2.0_amd64.deb and python-ckan_2.1_amd64.deb packages respectively.
Download the CKAN package for the new minor release you want to upgrade to (replace the version number with the relevant one):
Install the package with the following command:
sudo dpkg -i python-ckan_2.1_amd64.deb
If you have changed the Apache, Nginx or who.ini configuration files, you will get a prompt like the following, asking whether to keep your local changes or replace the files. You generally would like to keep your local changes (option N, which is the default), but you can look at the differences between versions by selecting option D:
Configuration file `/etc/apache2/sites-available/ckan_default' ==> File on system created by you or by a script. ==> File also in package provided by package maintainer. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** ckan_default (Y/I/N/O/D/Z) [default=N] ?
Your local CKAN configuration file in /etc/ckan/default will not be replaced.
The install process will uninstall any existing CKAN extensions or other libraries located in the src directory of the CKAN virtualenv. To enable them again, the installation process will iterate over all folders in the src directory, reinstall the requirements listed in pip-requirements.txt and requirements.txt files and run python setup.py develop for each. If you are using a custom extension which does not use this requirements file name or is located elsewhere, you will need to manually reinstall it.
If there have been changes in the Solr schema (check the Changelog to find out) you need to restart Jetty for the changes to take effect:
sudo service jetty restart
If you have any CKAN extensions installed from source, you may need to checkout newer versions of the extensions that work with the new CKAN version. Refer to the documentation for each extension. We recommend disabling all extensions on your ini file and re-enable them one by one to make sure they are working fine.
Rebuild your search index by running the ckan search-index rebuild command:
sudo ckan search-index rebuild -r
See search-index: Rebuild search index for details of the ckan search-index rebuild command.
Finally, restart Apache and Nginx:
sudo service apache2 restart sudo service nginx restart
