WordPress Basic Environment Configuration and Quick Installation Guide

Basic Environment Requirements and Preparation Work

Before starting to install WordPress, it is crucial to ensure that your server or local computer meets the minimum requirements for its operation. An improperly configured environment can lead to installation failures, slow website performance, or even security vulnerabilities.

Version requirements for server software

WordPress is an application built on top of PHP and MySQL, so there are specific requirements for both of these technologies. The official recommendation is to use PHP 7.4 or a later version; it is even better to use PHP 8.0 or higher for improved performance and better security support. For the database, MySQL 5.6 or a later version, or the compatible MariaDB 10.1 or later versions, are required. You can choose either Apache or Nginx as your web server – both are widely supported. Additionally, make sure that the necessary PHP extensions are enabled. mysqli(Or mysqlnd）、openssl、curl、dom、exif、fileinfo、hash、mbstring and xml。

Create and configure a database

Whether you are using a local environment or a remote host, you will need a dedicated database. If you are using a shared virtual host, you can usually create a database through the “MySQL Database Wizard” in the control panel (such as cPanel). If you are managing the server yourself, you can use the command line or the phpMyAdmin tool to perform this task. Create a new database and note down its name. Next, create a separate user for that database and grant that user “all permissions” on the database. Make sure to carefully record the database name, username, password, and the database host address (which is usually the same as the server address). localhostHowever, this may vary in certain web hosting environments.)
