Installing 6.0.18

Please see the installation guide for advice on getting started with Passenger. Coming from a language other than Ruby, Python, Meteor or Node? Even if we didn't write a specific tutorial for your language, we made a generic guide that shows you the steps.

Upgrading to 6.0.18

Note for Enterprise Linux 8 & 9 users: You will need to uninstall the Nginx package that was previously used with Passenger, change module streams, and then upgrade Passenger.

The following steps are a possible approach:

sudo yum remove nginx
sudo yum module reset nginx
sudo yum module enable -y nginx:$(sudo yum module list nginx | cut -d ' ' -f 2 | grep -Ee '^[0-9\.]+
