EL 8 / 9 cannot update passenger nginx module due to version conflict

I'm creating this issue in anticipation of people needing this info.

If you see the error below:

then you need to switch to the newest nginx module stream:

sudo yum remove -y nginx
sudo yum module reset nginx
sudo yum module enable -y nginx:$(sudo yum module list nginx | cut -d ' ' -f 2 | grep -Ee '^[0-9\.]+$' | sort -V | tail -1)
sudo yum install -y nginx-mod-http-passenger

Ran into this:

[Mon Sep 04 11:47:33 user3@server_f ~/sites/example] sudo yum module enable -y nginx:$(sudo yum module list nginx | cut -d ' ' -f 2 | grep -Ee '^[0-9\.]+$' | sort -V | tail -1)

What does sudo yum module list nginx | cut -d ' ' -f 2 | grep -Ee '^[0-9\.]+$' | sort -V | tail -1 on its own return?

[daBee]

9

[CamJN]

Ah, ok use this instead: sudo yum module enable -y nginx:$(sudo yum module list nginx | grep nginx | cut -d ' ' -f 2 | grep -Ee '^[0-9\.]+$' | sort -V | tail -1)

[daBee]

nginx version: nginx/1.22.1

OK, installed. I'll be watching how it behaves/works. Will this fall out with updates to nginx?

[CamJN]

Updates within a stream will work as expected, but if a new stream is added, say 1.24 for example, then it will require switching over. It's more work but people were quite loud about wanting this.
