Nginx is a growing open source web server software and PHP v7 is the latest version of the PHP engine. In this tutorial, we will use it to build a stack server LEMP (Linux, ANDNginx, MySQL, P). Nginx replaces the popular Apache package found on the LAMP stack.
what you will need
Before you begin this guide, you will need the following:
Step 1 – Install Nginx on CentOS 7
Since Nginx is not available in the CentOS repositories by default, we will install the repository EPEL running this command:
yum install epel-release -y
Next, we will install Nginx like so:
yum install nginx -y
Once the installation is complete, enable Nginx startup on boot and run it:
systemctl start nginx systemctl enable nginx
To check if Nginx is running, you can visit your IP address through the browser. First, identify your IP:
dig +short myip.opendns.com @resolver1.opendns.com
Then just copy and paste it into the browser and you will see a page similar to this:
Step 2 – Install MySQL (MariaDB)
Once the web server is installed, we can continue with the installation of MySQL. MariaDB is a community fork of the good old MySQL service. Since MariaDB comes with default CentOS repositories, we can run Yum to install it:
yum install mariadb-server mariadb -y
After finishing the installation, enable and start the service:
systemctl start mariadb systemctl enable mariadb
Lastly, run the initial setup script which will remove some of the default settings:
mysql_secure_installation
However, MariaDB will ask you for the root password, but since this is the initial installation, you don’t have one, so just press ENTER. The following message will ask if you want to set a root password, enter Y and follow the instructions:
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 authorization. New password: password Re-enter new password: password Password updated successfully! Reloading privilege tables.. … Success!
You can safely press the key ENTER and accept the default settings for all other questions. After completing the setup, continue with the PHP installation.
Step 3 – Install PHP v7.1.0
The first thing we will do is install the additional CentOS repository that contains the necessary packages for PHP v7.1:
wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm rpm -Uvh remi-release-7.rpm
Enable the php71 repository which is disabled by default:
yum install yum-utils -y yum-config-manager –enable remi-php71
Second, install the PHP package:
yum –enablerepo=remi,remi-php71 install php-fpm php-common
Install the common modules, such as , , among others:
yum –enablerepo=remi,remi-php71 install php-opcache php-pecl-apcu php-cli php-pear php-pdo php-mysqlnd php-pgsql php-pecl-mongodb php-pecl-redis php-pecl-memcache php -pecl-memcached php-gd php-mbstring php-mcrypt php-xml
Step 4 – Configure Nginx to work with PHP 7
Create a new Nginx configuration file by running vim or the text editor:
nano /etc/nginx/conf.d/default.conf
Enter this code:
server { listen 80; server_name your_server_ip; # note that these lines are originally from the “location /” block root /usr/share/nginx/html; index index.php index.html index.htm; location / { try_files $uri $uri/ =404; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } location ~ \.php$ { try_files $uri =404; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
IMPORTANT! Replace your_server_ip with the actual IP of your server
Save the file by pressing CTRL + X (CMD + X for Mac users). Restart Nginx for the change to take effect:
systemctl restart nginx
Now open the settings PHP-FPM:
nano /etc/php-fpm.d/www.conf
Find and replace these lines:
user = apache by user = nginx
group = apache per group = nginx
listen.owner = nobody by listen.owner = nginx
listen.group = nobody by listen.group = nginx
And finally, under ;listen = 127.0.0.1:9000 add this line:
listen = /var/run/php-fpm/php-fpm.sock
Once again, save the file by pressing CTRL + X. And finally, start php-fpm and enable it on startup:
systemctl start php-fpm.service systemctl enable php-fpm.service
conclusion
Installing the LEMP stack may require more configuration than the well-known LAMP setup, but you can be sure that you will be using the latest technology from both worlds: a fast PHP-FPM v7 processor package with Nginx modern web service.
