+# Installation on CentOS 9
+
+> This is a standalone, distribution-specific version of `INSTALL.md`. You do not need to read or follow the original file, but can refer to it for generic steps like setting up SSH keys (which are assumed to be common knowledge here)
+
+## Dependencies
+
+Before installing `piku`, you need to install the following packages:
+
+```bash
+dnf in -y ansible nginx nodejs npm postgresql postgresql-server python3 uwsgi
+```
+
+## Set up the `piku` user
+
+```bash
+export PAAS_USERNAME=piku
+adduser --groups nginx $PAAS_USERNAME
+# copy & setup piku.py
+sudo su - $PAAS_USERNAME -c "wget https://raw.githubusercontent.com/piku/piku/master/piku.py && python3 ~/piku.py setup"
+```
+
+## Set up SSH access
+
+See INSTALL.md
+
+## uWSGI Configuration
+
+[FYI The uWSGI Emperor – multi-app deployment](https://uwsgi-docs.readthedocs.io/en/latest/Emperor.html)
+
+```bash
+sudo ln -s /home/$PAAS_USERNAME/.piku/uwsgi/uwsgi.ini /etc/uwsgi.d/piku.ini
+sudo systemctl restart uwsgi
+```
+
+## `nginx` Configuration
+
+[FYI Setting up and configuring NGINX](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/deploying_web_servers_and_reverse_proxies/setting-up-and-configuring-nginx_deploying-web-servers-and-reverse-proxies)
+
+```bash
+echo "include /home/$PAAS_USERNAME/.piku/nginx/*.conf;" > /usr/share/nginx/modules/piku.conf
+sudo systemctl restart nginx
+```
+
+## Set up systemd.path to reload nginx upon config changes
+
+```bash
+# Set up systemd.path to reload nginx upon config changes
+sudo su -
+git clone https://github.com/piku/piku.git # need a copy of some files
+cp -v piku/piku-nginx.{path,service} /etc/systemd/system/
+systemctl enable piku-nginx.{path,service}
+systemctl start piku-nginx.path
+# Check the status of piku-nginx.service
+systemctl status piku-nginx.path # should return `active: active (waiting)`

-## Setting up the `piku` user
 
-`piku` requires a separate user account to run. To create a new user with the right group membership (we're using the built-in `www-data` group because it's generally thought of as a less-privileged group), enter the following commands:
+## Set up the `piku` user, Set up SSH access
 
-```bash
-# pick a username
-export PAAS_USERNAME=piku
-# create it
-sudo adduser --disabled-password --gecos 'PaaS access' --ingroup www-data $PAAS_USERNAME
-```
-
-This user _is not supposed to login to your system_. Instead, you'll interact with `piku` via SSH, and set things up by using `su`:
-
-```bash
-# copy your public key to /tmp (I'm assuming it's the first entry in authorized_keys)
-head -1 ~/.ssh/authorized_keys > /tmp/pubkey
-# install piku and have it set up SSH keys and default files
-sudo su - $PAAS_USERNAME -c "wget https://raw.githubusercontent.com/piku/piku/master/piku.py && python3 ~/piku.py setup && python3 ~/piku.py setup:ssh /tmp/pubkey"
-rm /tmp/pubkey
-```
-
-The `setup` output should be something like this:
-
-```
-Creating '/home/piku/.piku/apps'.
-Creating '/home/piku/.piku/repos'.
-Creating '/home/piku/.piku/envs'.
-Creating '/home/piku/.piku/uwsgi'.
-Creating '/home/piku/.piku/uwsgi-available'.
-Creating '/home/piku/.piku/uwsgi-enabled'.
-Creating '/home/piku/.piku/logs'.
-Setting '/home/piku/piku.py' as executable.
