How to install apache_exporter on Plesk VPS

[BenRoe]

It's not an issue, but hopefully it saves you some time and brain cells.

Note: Apache runs on port 7080 and not on 80 on a Plesk server

apache2ctl -M | grep status
// output should be: status_module (shared)
nano /etc/apache2/mods-enabled/status.conf

/etc/apache2/mods-enabled/status.conf

        <Location /server-status>
                SetHandler server-status
                Require local
                Require ip 127.0.0.1
        </Location>

service apache2 restart

sudo groupadd --system prometheus
sudo useradd -s /sbin/nologin --system -g prometheus prometheus

cd /tmp
wget https://github.com/Lusitaniae/apache_exporter/releases/download/v0.11.0/apache_exporter-0.11.0.linux-amd64.tar.gz
tar xvfz apache_exporter-0.11.0.linux-amd64.tar.gz
cd apache_exporter-0.11.0.linux-amd64
mv apache_exporter /usr/local/bin/apache_exporter
chown prometheus:prometheus /usr/local/bin/apache_exporter
