Setting up a LAMP environment (CentOS 8)

A LAMP environment refers to a web application platform built on a Linux system, consisting of Linux, Apache, MySQL or MariaDB, and PHP. This topic describes how to deploy a LAMP environment on a CentOS 8.3 instance.

Software versions

Operating system: In the example provided in this topic, CentOS 8.3 is used.

Apache: A web server with stable performance. In the example provided in this topic, Apache 2.4.37 is used.

MySQL/MariaDB: A database management system. In the example provided in this topic, MariaDB 15.1 and MySQL 8.0.26 are used.

PHP: A server-side scripting language embedded in HTML documents. In the example provided in this topic, PHP 7.3.20 is used.

Prerequisites

A Linux instance is purchased. For more information, see Purchasing ECS instances.

An EIP is associated with the Linux instance, enabling the instance to connect to the Internet. For information about how to associate an EIP with an ECS instance, see Associating EIPs.

Step 1: Install and configure Apache

Remotely connect to and log in to the ECS instance. For more information, see Logging in to Linux instances.

Execute the following command to install Apache. In the example provided in this topic, Apache 2.4.6 is installed.

yum install httpd -y

Execute the following command to view the Apache version.

httpd -v

If the following output is displayed, Apache is installed.

Server version: Apache/2.4.37 (centos)
Server built: Nov 16 2020 16:18:20

Execute the following command to start the Apache service.

systemctl start httpd

Execute the following command to specify that the Apache service automatically starts upon instance startup.

systemctl enable httpd

In the local browser, enter http://<ECS instance EIP>/ to access Apache.

If the following output is displayed, Apache is set up successfully.

Step 2: Install and configure MariaDB/MySQL

Install and configure MariaDB

Execute the following command to install MariaDB.

dnf -y install @mariadb

Execute the following command to view the MariaDB version.

mysql -V

If the following output is displayed, MariaDB is installed.

mysql Ver 15.1 Distrib 10.3.28-MariaDB, for Linux (x86_64) using readline 5.1

Execute the following command to start the MariaDB service and specify that it automatically starts upon instance startup.

systemctl enable --now mariadb

Execute the following command to check whether the MariaDB service is started.

systemctl status mariadb

If Active: active (running) is displayed in the output, the MariaDB service is started.

Execute the following command to perform MariaDB security operations and specify the password.

mysql_secure_installation

Press the Enter key to confirm the password.

Enter y and press the Enter key to confirm modification of the database password for the root user.

Specify the MariaDB password and press the Enter key. The password you enter is not displayed by default.

Enter the new password again and press the Enter key to confirm your new password.

tip

Enter a password that meets the strength requirements of the password verification policy.

Enter y and press the Enter key to remove the anonymous user.

Enter y and press the Enter key to prohibit remote login by the root account.

Enter y and press the Enter key to delete the test database and its access permission.

Enter y and press the Enter key to reload the authorization table.

Install and configure MySQL

Execute the following command to install MySQL.

dnf -y install @mysql

Execute the following command to view the MySQL version.

mysql -V

If the following output is displayed, MySQL is installed.

mysql Ver 8.0.26 for Linux on x86_64 (Source distribution)

Execute the following command to start the MySQL service and specify that it

automatically starts upon instance startup.

systemctl enable --now mysqld

Execute the following command to check whether the MySQL service is started.

systemctl status mysqld

If Active: active (running) is displayed in the output, the MySQL service is started.

Execute the following command to perform MySQL security operations and specify the password.

mysql_secure_installation

Enter y and press the Enter key to start the relevant configuration.

Select the password verification policy strength, and enter 2 and press the Enter key. We recommend that you select a high-strength verification policy. A value of 0 specifies low strength, 1 specifies medium strength, and 2 specifies high strength.

Specify the new MySQL password and press the Enter key. The password you enter is not displayed by default.

Enter the new password again and press y to confirm your new password.

tip

Enter a password that meets the strength requirements of the password verification policy.

Enter y and press the Enter key to remove the anonymous user.

Specify whether to allow remote connections to MySQL:

To prohibit remote connections: Enter y and press the Enter key.

To allow remote connections: Enter n and press the Enter key.

Enter y and press the Enter key to delete the test database and its access permission.

Enter y and press the Enter key to reload the authorization table.

Step 3: Install and configure PHP

Execute the following command to add and update the EPEL repository.

dnf -y install epel-release
dnf -y update epel-release

Execute the following command to delete cached unused packages and update the software repository.

dnf clean all
dnf makecache

Execute the following command to enable the php:7.3 module.

dnf -y module enable php:7.3

In the example provided in this topic, php:7.3 is used. If you want to use php:7.4, you need to first install the Remi repository and then start the PHP module. Command for installing the Remi repository: dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm.

Execute the following command to install the corresponding PHP modules.

dnf -y install php php-curl php-dom php-exif php-fileinfo php-fpm php-gd php-hash php-json php-mbstring php-mysqli php-openssl php-pcre php-xml libsodium

Execute the following command to view the PHP version.

php -v

If the following output is displayed, PHP is installed.
