I have installed the cyberpanel on centos 7 but failed. After the installation process I received this message. I tried to access http://ip/8090 but couldn’t. Hope the helping.

Since you just started, just restart from scratch. Reinstall Centos 7 minimal, then install CyberPanel again. Takes less than 1 hour total, much easier than to troubleshoot a failed install.

No need to Install OS again !

You can run

yum history list|awk ‘$1 ~ /[0-9]+/ {print $1}’| while read a; do yum history undo -y $a; done

it will remove all the packages that are installed !
then

remove /etc/cyberpanel and /etc/letsencrypt

and run installation again !!
