Contribution & Support --- # Introduction ### What is Centmin Mod LEMP web stack? * A LEMP web stack is a set of open source Linux software which form the platform (web stack) where a web site's files (text, CSS files, javascript, fonts, videos & images) and data can be served to a visitor. Every web site you visit on the internet is served from some form of web stack bundle. When your web browser connects to a web site, it is communicating with a web server requesting files hosted on the web server. * Centmin Mod LEMP web stack installer is a [open source project](https://github.com/centminmod/centminmod) which fully automates most of LEMP stack install, configuration, base optimisation and best recommended practices and settings for CentOS, Nginx, MariaDB MySQL, PHP, CSF Firewall security and other installed software. The whole process is done via the core [centmin.sh](https://centminmod.com/menu.html) shell based script which can install Centmin Mod via a curl one liner install method. * Centmin Mod LEMP web stack is developed by George Liu ([eva2000](https://twitter.com/centminmod)) for performance and scalability in mind. Out of box Centmin Mod installs will perform better than many other LEMP stack setups. --- # LEMP stands for: * **Linux** - Linux operating system. In Centmin Mod's case CentOS Linux. * **Nginx** - pronounced Engine-X is the web server listening on port 80 (HTTP) and port 443 (HTTPS). Nginx is what visitors visiting a web site interface with first as Nginx serves the data hosted on a web site to visitors. Nginx is much more than just a web server - see [nginx.org](http://nginx.org/en/) for more details. Sometimes LEMP is refered to LNMP stack wher N is Nginx. * **MySQL** - MariaDB MySQL database server fork, MariaDB. MySQL is an open source relational database server that listens on port 3306 by default and holds database data which is queried and written to by MySQL clients such as PHP. * **PHP** - a server sided scripting language [[wikipedia](https://en.wikipedia.org/wiki/PHP)]. Centmin Mod compiles PHP as PHP-FPM (FastCGI Process Manager) which listens on port 9000 by default which can communicate with MariaDB MySQL database server to retrieve and store web site data. ---  --- # centmin.sh shell menu [centmin.sh shell based menu](https://centminmod.com/menu.html)  --- # Get A Server * Centmin Mod only installs on CentOS 6 or CentOS 7 Linux distributions. * Highly recommended to use latest CentOS 7.x 64bit Linux distribution. Currently CentOS 7.7 is latest. * Read the minimum and recommended memory and disk space requirements on official install page [here](https://centminmod.com/install.html). * To install Centmin Mod you need to rent a web server which can be either a dedicated server or VPS server (virtualised private server). VPS servers can either use OpenVZ, Xen or KVM based virtualisation. * Sever rentals can be on a monthly basis or some web hosts offer hourly billed servers which are perfect for Centmin Mod test servers. Recommended hourly billed VPS providers: [Upcloud.com](https://centminmod.com/upcloud/), [Linode.com](https://centminmod.com/linode/), [DigitalOcean.com](https://centminmod.com/digitalocean/) and [Vultr.com](https://centminmod.com/vultr/).
