LAMP es derivado de las primeras letras Linux, Apache HTTP, MySQL/MariaDB, y PHP/Perl/Python.
En este turorial ve la manera de instalar un servidor LAMP en RHEL/CentOS/Scientific Linux 7.
El hostname y dirección IP son server.lamp.local y 192.168.1.101/24 respectivamente.
Instalación de Apache
Apache es un servidor web open-source y multi-plataforma. Provee muchas prestaciones como servidor web incluido CGI, SSL y dominios virtuales.
Los siguientes comandos deben ser corridos con privilegios root.
Para instalar Apache, ingresar el siguiente comando en el terminal:
yum install httpd -y
Iniciar los servicios Apache y configuración para que se levante automáticamente cuando se inicie el Sistema Operativo:
systemctl start httpd systemctl enable httpd
Las configuraciones en el firewall para poder tener acceso remoto:
firewall-cmd --permanent --add-service=http systemctl restart firewalld
Probando Apache
Abrir el navegador con la dirección http://localhost/ o http://dirección-ip/.
Instalar MariaDB
MariaDB remplaza a MySQL.
Ahora, comenzamos instalando MariaDB con lo siguiente:
yum install mariadb-server mariadb -y
Iniciamos el servicio de MariaDB y lo configuramos para se levante automaticamente al reiniciar el servidor:
systemctl start mariadb systemctl enable mariadb
Configuramos la contraseña root MySQL
Por defecto, la contraseña root en MySQL es vacía. Para prevenir accesos no autorizados a MySQL, ingresamos una contraseña para root. Ingresar el siguiente comando para configurar la contraseña de root:
mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] y ## Enter Y and press Enter New password: ## Enter new password Re-enter new password: ## Enter password again Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ## Enter Y and press Enter ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y ## Enter Y and press Enter ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] y ## Enter Y and press Enter - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ## Enter Y and press Enter ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
Instalar PHP
Instalamos PHP con el siguiente comando:
yum install php php-mysql php-gd php-pear -y
Probamos PHP:
Creamos un archivo de ejemplo “testphp.php” en la carpeta root de Apache con las siguientes líneas:
nano /var/www/html/testphp.php
Adicionamos lo siguiente.
Reiniciamos el servicio httpd:
systemctl restart httpd
En el navegador dirigimos un link http://server-ip-address/testphp.php. Esto debe mostrar el Acerca de php.
