It is increasingly common to find LEMP servers on the market. This is because it allows you to have a more prepared web server for more numerous connections. As well as many simultaneous requests. Unlike LAMP, installing LEMP on Ubuntu 18.04 requires a few extra steps to make everything work. Anyway, it’s not a complex process and it is within most people’s reach. So, in this post, you will learn to install LEMP on Ubuntu 18.04.
LEMP refers to a set of software that together provides a web server. The main difference with LAMP is that it replaces Apache with another HTTP server, usually Nginx. We have talked a lot about Nginx, and it is one of the most important applications for the web, where a large number of websites use it. The main features of Nginx are performance and scalability.
Install LEMP on Ubuntu 18.04
Install Ubuntu 18.04
If you have not yet installed Ubuntu 18.04 or do not know how to do it. Here is a tutorial for you to do it without problems.
Now we can install the second component of LEMP. Nginx is a wonder as a web server. Its performance is enviable and that’s why it has become a formidable option to serve websites. Especially when these websites have a lot of traffic.
Nginx is in the official Ubuntu 18.04 repositories, so open a terminal and run.
:~$ sudo apt install nginx
And that’s enough. If you use a firewall like ufw, remember to enable ports 80 and 443.
Then open a web browser and access your server. You can do it by the IP address of the same or through the domain.
So, Nginx is properly installed.
Install PHP to work with Nginx
Now it’s PHP’s turn, so let’s install it together with php-fpm to work with Nginx.
:~$ sudo apt install php php-cli php-fpm php-mysql
After that, edit the php.ini file.
:~$ sudo nano /etc/php/7.2/fpm/php.ini
And change the following line:
Save and close the file. Next, restart php-fpm.
:~$ sudo systemctl restart php7.2-fpm
Now you have to make some changes to Nginx to make everything work well. So edit the following file:
:~$ sudo nano /etc/nginx/sites-available/default
On the server section. Add index.php. And set the server_name to the server IP or the FQDN.
Then, scroll down to the location section and uncomment the include, fastcgi_pass, location, deny all lines. As in the image.
Save and close the file. Then, restart Nginx.
:~$ sudo systemctl restart nginx
Next, test PHP. To do it, create a new file .php and open it from the web browser.
:~$ sudo nano /var/www/html/test.php
And add the following.
<? phpinfo(); ?>
Finally, open it using the web browser.
Now we need to install MariaDB for this, we will use the version that is in the official repositories. So, let’s install it.
:~$ sudo apt install mariadb-server
Then, configure it using the mysql_secure_installation script.
:~$ sudo mysql_secure_installation
With this script, you will be able to define the root password and other options. So read them and answer what your server needs.
And that’s it.
As you can see, installing LEMP on Ubuntu 18.04 is quite a simple process. With this, you will have a web server quite competent and specialized in websites with high traffic.
