Installazione del framework PHP Laravel su CentOS 7

In questo articolo andremo a descrivere come installare il framework PHP Laravel su CentOS 7.

Consideriamo di partire da una macchina CentOS 7 preinstallata ( qui l’ articolo per l’installazione ) ed aggiorniamola

yum update

in un precedente articolo abbiamo descritto come installare PHP 7.x su CentOS 7 ( qui l’ articolo), seguiamo passo passo la procedura installando il repository epel

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

ed il repository relativo al php 7.x

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

inoltre avendo diverse versioni di PHP, scegliamo attraverso l’utility di yum quale repository di pacchetti PHP utilizzare

yum install yum-utils

scegliamo la versione PHP 7.4

yum-config-manager --enable remi-php74

Plugin abilitati:fastestmirror

a questo punto installiamo PHP ed i moduli necessari per il framework Laravel

yum install php php-zip php-mysql php-mcrypt php-xml php-mbstring

installiamo il web server HTTPD

yum install httpd

avviamolo e abilitiamo l’ avvio automatico al boot

systemctl start httpd

systemctl enable httpd

Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

installiamo il database

yum install mariadb-server

avviamolo e abilitiamo l’ avvio automatico al boot

systemctl start mariadb.service

systemctl enable mariadb.service

Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

rendiamo sicuro il database MariaDB

mysql_secure_installation

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):INVIO

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

New password:
Re-enter new password:
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

… 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

… 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

– 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

Cleaning up…

All done! If you’ve completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Per installare Laravel abbiamo necessità del gestore dei pacchetti PHP Composer, quindi

yum install git unzip vim

curl -sS https://getcomposer.org/installer | php

mv composer.phar /usr/bin/composer

chmod +x /usr/bin/composer

installiamo Laravel

cd /var/www

git clone https://github.com/laravel/laravel.git

installiamo le dipendenze PHP di Laravel

cd /var/www/laravel

composer install

impostiamo i permessi sui singoli file

chown -R apache.apache /var/www/laravel

chmod -R 755 /var/www/laravel

chmod -R 755 /var/www/laravel/storage

per i nostri scopi dimostrativi impostiamo il Selinux in modalità permissive

setenforce 0

vim /etc/selinux/config

impostiamo la variabile SELINUX

SELINUX=permissive

La configurazione di Laravel passa per il file .env, all’interno della cartella di progetto

cd /var/ww/laravel

creiamo il file partendo dal template fornito da Laravel

cp .env.example .env

generiamo la chiave

php artisan key:generate

Application key set successfully.

Creiamo il Virtual host su Apache per accedere al framework Laravel via browser

vim /etc/httpd/conf.d/laravel.conf

<VirtualHost *:80>
DocumentRoot /var/www/laravel/public

<Directory /var/www/laravel>
AllowOverride All
</Directory>
</VirtualHost>

riavviamo il web server

systemctl restart httpd

accediamo tramite browser a Laravel http://ip_server, avremo
