You'll need to set up your network:
 +
 +
Log into your server as root and<syntaxhighlight lang="bash">
 +
nmtui
 +
ip address
 +
ping google.com
 +
</syntaxhighlight>I'd suggest an update is in order<syntaxhighlight lang="bash">
 +
dnf update
 +
 +
</syntaxhighlight>Configure some basic tools and settings<syntaxhighlight lang="bash">
 +
dnf install setools-console
 +
dnf config-manager --set-enabled powertools
 +
dnf install epel-release
 +
dnf install policycoreutils-python-utils
 +
dnf install rsyslog
 +
dnf install cockpit
 +
systemctl enable cockpit.socket --now
 +
systemctl start cockpit.socket
 +
dnf install setroubleshoot-server
 +
setsebool -P allow_httpd_anon_write=1
 +
setsebool -P httpd_can_network_connect_db 1
 +
reboot
 +
</syntaxhighlight>Install koji hub and pre-requisites<syntaxhighlight lang="bash">
 +
dnf install koji-hub mod_ssl
 +
dnf module enable postgresql:10
 +
dnf install postgresql-server
 +
dnf install koji
 +
</syntaxhighlight>We'll be using ssl certificates so let's create the koji ssl working directories and edit the koji ssl config file<syntaxhighlight lang="bash">
 +
mkdir -p /etc/pki/koji/{certs,private,confs}
 +
cd /etc/pki/koji
 +
nano ssl.cnf
 +
 +
</syntaxhighlight>and insert the following into ssl.conf
 +
 +
I suggest you change the defaults in [req_distinguished_name] to yours to make it easier when generating certs....
