The following commands work for any hosting environment, but it’s primarily for users that are in an environment with no suEXEC, like one where PHP is running as an Apache module.
In this kind of environment, all web-based processes are owned by user nobody, unlike an environment with suEXEC, where these are owned by the user.
Once you’ve accessed your site via SSH, change in to the directory where Magento is installed. Run the following commands to upgrade Magento:
-
./pear upgrade-all
-
rm -rf downloader/pearlib/cache/* downloader/pearlib/download/*
If you receive an error, that means the PEAR registry has not been initialized. You need to run the following commands:
-
./pear mage-setup .
-
./pear install magento-core/Mage_All_Latest
-
rm -rf downloader/pearlib/cache/* downloader/pearlib/download/*
This is only required once, after it’s initialized you don’t need to do this again and can use the first command listed in this article.
You also might need to clear your cache directory out after an upgrade:
-
rm -rf var/cache/*
To install an extension via SSH, run the following command from the directory where Magento is installed:
-
./pear install EXTENSION_KEY
Replace EXTENSION_KEY with the appropriate value.
For example, to install the Blue Skin, you would do this:
-
./pear install magento-core/Interface_Frontend_Default_Default_Blue
Be sure to clear the cache out after you’re done:
-
rm -rf downloader/pearlib/cache/* downloader/pearlib/download/*
