In this article, we are going to show you how to install LAMP (Linux Apache, MariaDB and PHP) on CentOS 7…

What is LAMP?

LAMP is actually an acronym for the Web Services Stack, consisting of Linux, Apache HTTP Server , MySQL or MariaDB DBMSand PHP, Perl or Python. All components are software with free and open sourcewhich are suitable for creating dynamic web pages.

Update the system

As always, make sure your CentOS 7 completely updated using the following commands:

screen -U -S lamp-centos7
yum update

Install MariaDB

MariaDB is the default database server in CentOS 7so go ahead and install it with the following command:

yum install mariadb mariadb-server mysql

After installation, add bind-address = 127.0.0.1 in /etc/my.cnf.d/server.cnf, to link MariaDB locally:

vim /etc/my.cnf.d/server.cnf

[mysqld]
#log-bin=mysql-bin
#binlog_format=mixed
bind-address = 127.0.0.1

Restart the MariaDB database server and enable it to autostart the system with:

systemctl restart mariadb
systemctl status mariadb
systemctl enable mariadb

Finally, you can run the script mysql_secure_installation after installation to finish configuring MariaDB. For instance:

mysql_secure_installation

Enter current password for root (enter for none): ENTER
Set root password? [Y/n] Y
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

Install Apache

Then proceed to install Apache, OpenSSL and mod_ssl using yum, так:

yum install httpd openssl mod_ssl

Restart Apache and add it to start automatically on your system with:

systemctl restart httpd
systemctl status httpd
systemctl enable httpd

Test the setting by opening, for example, http: // your_server_ip_address / in your browser. You should see the default Apache page, for example:

Excellent. Now let’s configure some additional Apache parameterseg hide your version number, its banner, etc … by adding the following to /etc/httpd/conf.d/options.conf.

vim /etc/httpd/conf.d/options.conf

TraceEnable off

## Disable Signature
ServerSignature Off

## Disable Banner
ServerTokens Prod

Testing the Apache configuration file and restarting the web server for the changes to take effect:

apachectl configtest
systemctl restart httpd
systemctl status httpd

Install PHP

In order to be able to run PHP based web applications, we must add PHP support for Apache web serverso let’s install some required packages with yum:

yum install php php-mysql

In addition, you can install some other PHP extensions required for your applications. Here’s a list:

php-bcmath          : модуль для PHP-приложений для использования библиотеки BCMath
php-cli             : Интерфейс командной строки для PHP
php-common          : Общие файлы для PHP
php-dba             : Модуль абстракции базы данных для PHP-приложений
php-devel           : Файлы, необходимые для построения расширений PHP
php-embedded        : PHP библиотека для встраивания в приложения
php-enchant         : расширение enchant правописания для PHP-приложений
php-fpm             : PHP FastCGI Process Manager
php-gd              : модуль для PHP-приложений для использования библиотеки графики gd
php-intl            : расширение для PHP интернационализации приложений
php-ldap            : модуль для PHP-приложений, которые используют LDAP
php-mbstring        : модуль для PHP-приложений, которые требуют обработки многобайтовых строк
php-mysql           : модуль для PHP-приложений, использующих базы данных MySQL
php-mysqlnd         : модуль для PHP-приложений, которые используют базы данных MySQL
php-odbc            : Модуль для PHP приложений, использующих базы данных ODBC
php-pdo             : Модуль абстракции доступа к базам данных для PHP-приложений
php-pear.noarch     : PHP Extension и Application Repository framework
php-pecl-memcache   : Расширение для работы с кэширования демона Memcached
php-pgsql           : Модуль базы данных PostgreSQL для PHP
php-process         : Модули для PHP скрипт с использованием интерфейсов системного процесса
php-pspell          : модуль для PHP-приложений для использования pspell интерфейсов
php-recode          : модуль для PHP-приложений для использования библиотеки перекодирования
php-snmp            : Модуль для PHP приложений, запрашивающих SNMP-управляемых устройств
php-soap            : Модуль для PHP-приложений, использующих протокол SOAP
php-xml             : модуль для PHP-приложений, использующих XML
php-xmlrpc          : модуль для PHP-приложений, использующих протокол XML-RPC

Ok, let’s continue with the PHP configuration. Edit the file /etc/php.ini and set the following parameters:

vim /etc/php.ini

date.timezone = Europe/Moscow
memory_limit = 64M
expose_php = Off

restart Apache using systemctl for the changes to take effect:

systemctl restart httpd
systemctl status httpd

Testing the loading of the PHP module in Apache using:

httpd -M | grep php

also

## php -v

You can create a test script info.phpby using the following command:

echo -e "<?phpntphpinfo();" > /var/www/html/info.php

and access it with the following command:

curl -I $(curl -s icanhazip.com)/info.php

Install APACHE VHOST

Now you have to configure Apache Virtual Host directives, to be able to host multiple domainsEven SSL using powered one one IP address. So create a file /etc/httpd/conf.d/vhosts.conf and add the following:

cat /etc/httpd/conf.d/vhosts.conf

# Загрузка моих vhosts
IncludeOptional vhosts.d/*.conf

This tells Apache to load configuration files ending in .conf who are in /etc/httpd/vhosts.d… As you might have guessed, this is where we list our virtual hosts, so let’s configure one for my_domain.com and another for my_domain2.ru

VHOST for my_domain.com

## cat /etc/httpd/vhosts.d/my_domain.com.conf

<VirtualHost YOUR_SERVER_IP:80>
    ServerAdmin [email protected]_domain.com
    DocumentRoot "/var/www/html/my_domain.com"
    ServerName my_domain.com
    ServerAlias www.my_domain.com
    ErrorLog "/var/log/httpd/my_domain.com-error_log"
    CustomLog "/var/log/httpd/my_domain.com-access_log" combined

    <Directory "/var/www/html/my_domain.com/">
        DirectoryIndex index.html index.php
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

VHOST for my_domain.net

## cat /etc/httpd/vhosts.d/my_domain.net.conf

<VirtualHost YOUR_SERVER_IP:80>
    ServerAdmin [email protected]_domain.net
    DocumentRoot "/var/www/html/my_domain.net"
    ServerName my_domain.net
    ServerAlias www.my_domain.net
    ErrorLog "/var/log/httpd/my_domain.net-error_log"
    CustomLog "/var/log/httpd/my_domain.net-access_log" combined

    <Directory "/var/www/html/my_domain.net/">
        DirectoryIndex index.html index.php
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Finally, restart Apache for the changes to take effect:

apachectl configtest
systemctl restart httpd
systemctl status httpd
