Setting up a LAMP environment (CentOS 7)

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 7.6 instance.

Software versions

Operating system: In the example provided in this topic, CentOS 7.6 is used. You can also use CentOS 7.9, veLinux 1.0 (CentOS compatible version), or other CentOS 7 series images.

Apache: A web server with stable performance. In the example provided in this topic, Apache 2.4.6 is used.

MySQL/MariaDB: A database management system. In the example provided in this topic, MariaDB 15.1 and MySQL Community Edition 8.4.3 are used.

PHP: A server-side scripting language embedded in HTML documents. In the example provided in this topic, PHP 7.0.33 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/2.4.6 (CentOS)
Server built: Mar 24 2022 14:57:57

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.

yum -y install mariadb-server mariadb-client

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 5.5.68-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 download the RPM package for the MySQL Community Edition repository configuration file.

wget https://dev.mysql.com/get/mysql84-community-release-el7-1.noarch.rpm

Execute the following command to install the MySQL 8.4 Community Edition software repository configuration file.

rpm -Uvh mysql84-community-release-el7-1.noarch.rpm

Execute the following command to install MySQL 8.4.

yum -y install mysql-community-server

tip

If the Failing package is: mysql-community-libs-compat-8.4.3-1.el7.x86_64 error occurs, the GPG key for MySQL is upgraded and needs to be retrieved again. In this case, execute the following commands in sequence: rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022 and yum -y install mysql-server.

Execute the following command to view the MySQL version.

mysql -V

If the following output is displayed, MySQL is installed.

mysql Ver 8.4.3 for Linux on x86_64 (MySQL Community Server - GPL)

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 view the initial password that was automatically specified during MySQL installation.

grep 'temporary password' /var/log/mysqld.log

Output similar to the following is displayed. In this example, the initial password is 0zNwvmpr:fOd.

2021-09-17T09:31:12.142217Z 1 [Note] A temporary password is generated for root@localhost: 0zNwvmpr:fOd

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.

Step 3: Install and configure PHP

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

wget -O /etc/yum.repos.d/epel.repo http://mirrors.ivolces.com/repo/epel-7.repo

Execute the following command to add the Remi repository.

rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Execute the following command to install the yum-config-manager repository management tool.

yum -y install yum-utils

Execute the following command to enable the specified Remi PHP 7.0 repository by using yum-config-manager.

yum-config-manager --enable remi-php70

Execute the following command to install PHP 7.0 and common modules.

yum -y install php php-mysqlnd php-fpm

Execute the following command to start the PHP-FPM service.
