I installed on centos 7.2, just used one minutes and see "Congratulations! Installed successfully!"
Unfortunately, can't access aapanel from browser "This site can’t be reached"
also tried on centos8, same.
only one warning during installing:
WARNING: You are using pip version 20.1.1; however, version 20.2.1 is available.
You should consider upgrading via the '/www/server/panel/pyenv/bin/python3.7 -m pip install --upgrade pip' command.
