Build a LAMP stack (Linux, Apache, MySQL, PHP) - CentOS 7


To build a dynamic web application, you need what has been coined a “stack” - which is developer lingo for an integrated set of software that has all of the components your application needs.

Most stacks have the same types of components and differ mainly in which pieces of software they use for those components. For example, we’ll look at LAMP (which this article covers):

LAMP Software: Linux (e.g. CentOS), Apache, MySQL, PHP

If you're astute, maybe you noticed that LAMP is just an acronym for the software the stack uses.
In this guide, we'll walk you through installing all of these components (except for Linux, which is already installed as your OS when you create the server).

Install Apache

  1. Before you begin any installation, make sure that your software is up to date:
    # sudo yum update
  2. Install Apache:
    # sudo yum install httpd
  3. Start Apache:
    # sudo systemctl start httpd.service
  4. Set Apache to start on server boot:
    # sudo systemctl enable httpd.service
  5. Verify that Apache is installed by going to:
    http://your server's IP address.
    If Apache is installed, the Apache Test Page displays.

Install MySQL

  1. Install MariaDB, which is a community-developed fork of MySQL:
    # sudo yum install mariadb-server mariadb
  2. Start the service:
    # sudo systemctl start mariadb
  3. Set MySQL to start on server boot:
    # sudo systemctl enable mariadb.service
  4. Run this command to finish setting up the installation:
    # sudo mysql_secure_installation
  5. You will be asked for the root password. Because you didn't set it earlier, press Enter to set a password now.
  6. Type "Y" to set the root password.
  7. Enter and confirm the new password.
  8. You will be asked more questions as part of the security configuration. It is a best practice to respond "Y" to these system prompts

Install PHP

  1. Install PHP:
    # sudo yum install php php-mysql
    Enter "Y" to install.
  2. Restart Apache:
    # sudo systemctl restart httpd.service

Install PHP modules

If your applications requires any PHP modules, you can install them now.
  1. View available PHP modules:
    # yum search php-
  2. The list displays the available PHP modules. To view the description of a specific package, use the following command:
    # yum info the name of the package you want to use
  3. Install the package you want:
    # sudo yum install the name of the package you want to use

Test PHP processing on Apache

  1. Create a new PHP file under the /var/www/html directory:
    # sudo vim /var/www/html/info.php
  2. When the file opens, type in the following code: 
    <?php
phpinfo();
?>
  3. Save and close the file:
    :wq!
  4. To verify it worked, type this URL in your browser:
    http://your server's IP address/info.php

A page displays with the PHP version, extensions, build date, and other information.

How to measure disk performance with fio and IOPing

Image
Introduction Whether it’s a server, or a PC for work, what usually limits performances is disk speed. Even if using SSDs, their speed is not yet comparable to that of RAM and CPU. There are different tools with or without a graphical interface, written for testing disks speed. There are also people who use  dd , for example: dd if=/dev/zero of=test_file bs=64k count=16k conv=fdatasync However, in our opinion dd is the worst software for benchmarking I/O performance. In fact: it is a single-threaded, sequential-write test. Of course, if running a web server, services do not do long-running sequential writes, and use more than one thread it writes a small amount of data, so the result can be influenced by caching or by RAID’s controller it executes for just a few seconds, and everyone knows that in this way it’s not possible to have consistent results there are no reading speed tests All these points just lead to one conclusion: better to use anything else. For disk benc

Apache is an open-source web server that can be configured to serve a single or multiple websites using the same Linode. This guide explains how to install and configure the Apache web server on CentOS 7. This guide is written for a root user.

To check your hostname run: # hostname # hostname -f The first command should show your short hostname, and the second should show your Fully Qualified Domain Name (FQDN). Update your system: # sudo su - # yum update Install and Configure Apache # yum install httpd Modify httpd.conf with your document root directory to point Apache to your site’s files. Add the <IfModule prefork.c> section below to adjust the resource use settings. The settings shown below are a good starting point for a 2GB: Before chang
