KeyHelp server control panel

Installation Requirements:

  • Operating system: Ubuntu LTS or Debian
  • Memory: At least 1 GB RAM
  • Architecture: 64-bit operating system
  • The installation must be performed on a clean system. All required services are installed and configured by KeyHelp.
  • The installation must be done as root user.

KeyHelp Installation
Log on to your server with root user and execute the following command:

wget https://install.keyhelp.de/get_keyhelp.php -O install_keyhelp.sh ; bash install_keyhelp.sh ;

After executing the command, KeyHelp will guide you through the installation.

If you get the message “ERROR: The certificate of ‘install.keyhelp.de’ is not trusted.“, you have to add “–no-check-certificate” as a wget parameter. Or install the “ca-certificates” package with the command “apt-get install ca-certificates”.

Welcome to your KeyHelp server control panel
Before you start setting up your server, here are some important tips to ensure the stability of your system.

  1. Do not change the default PHP Interpreter of your operating system.
    If you need other PHP versions, use the ones provided under Settings -> Configuration -> PHP Interpreter.
  2. Never upgrade your operating system version manually.
    Instead, always use the instructions and upgrade scripts that you can find here.

Debian

wget -O install.sh http://www.aapanel.com/script/install-ubuntu_6.0_en.sh && bash install.sh aapanel

Notice: Ensure that it is a clean operating system, there is no other environment with Apache/Nginx/php/MySQL installed (the existing environment can not be installed)

WARNING: You are using pip version 20.3.3; however, version 23.3.1 is available.
You should consider upgrading via the ‘/www/server/panel/pyenv/bin/python3.7 -m pip install –upgrade pip’ command.

/www/server/panel/pyenv/bin/python3.7 -m pip install --upgrade pip

It is recommended to use Chrome, Firefox, and edge browsers to access the panel login address

The main difference between NGINX and Apache web servers is that NGINX has event-driven architecture handling multiple requests within a single thread, while Apache is process-driven creating a thread per each request. Thus, allowing NGINX to have generally better performance.
