Apache Performance Tuning: MPM Modules
The keystone for understanding Apache server performance is by far the Multiprocessing Modules (MPMs). These modules determine the basis for how Apache addresses multiprocessing. Multiprocessing means running multiple operations simultaneously in a system with multiple central processing units (CPU Cores).
MySQL Performance: MyISAM vs InnoDB
A major factor in database performance is the storage engine used by the database, and more specifically, its tables. Different storage engines provide better performance in one situation over another. For general use, there are two contenders to be considered. These are MyISAM, which is the default MySQL storage engine, or InnoDB, which is an alternative engine built-in to MySQL intended for high-performance databases. Before we can understand the difference between the two storage engines, we need to understand the term “locking.”
How to Login to Manage
The Manage interface is Liquid Web's Account and Cloud Management Portal. From Manage, it is possible to control all of your servers and services, whether your deployment is one Cloud VPS or a combination of many dedicated servers and other cloud services.
Working with Composer & Examples
In the previous articles we worked through what composer is, who uses it, and how to install it. Here we will cover some basic use case examples of how to acquire packages using the composer tool we previously setup.
Installing Composer on cPanel servers
With a tool like Composer it is generally best to have the ability to run it as any user on the server and from any directory. This is generally referred to as being 'globally installed' as any user can access the tool from any location. In this guide we will detail how to install Composer globally on a cPanel based server.
Composer 101
Composer is a dependency manager for PHP, written in PHP. Specifically, it’s used to simplify the process of using PHP libraries in your projects. The use can range from getting a framework, including a library class, or open source projects; generally these packages are downloaded by Composer and then implemented by a developer in a website’s code.
Examples being: Silex MicroFramework, the infamous PHPMailer class, Laravel Framework, and many more - all of which can be found on Composer’s main repository Packagist.
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are common threats that every publicly accessible web server faces. The purpose of such attacks, in the simplest terms, is to flood a server with connections, overloading it and preventing from accepting legitimate traffic.
In addition to being able to manage traffic from a specific country or a list of countries, CSF allows you to manage access by country to specific ports. This can be useful if you need to ensure that a particular service is available globally (such as your web server on port 80) but want to restrict international access to services such as WHM/cPanel, SSH, or FTP.
One of the most-requested features on cPanel servers is the ability to manage and filter traffic at a country level. With the ConfigServer Firewall (CSF) plugin in WebHost Manager, you can do exactly that.
