The installation of a server LEMP Linux + Nginx + MySQL + PHP might be more useful and efficient than an Apache (server LAMP).
Nginx installation
It will be essential to know the machine’s IP address to install from ifconfig.
|
1 2 3 4 |
ifconfig eth0 | grep inet | awk '{ print $2 }' addr:10.0.0.8 |
From your system on Debian 8, we install nginx via the command :
|
1 2 3 4 |
sudo apt-get update sudo apt-get install nginx |
Your server nginx is now operational and available except if a rule prevent the streams HTTP and in this case, you have to check netfilter (iptables / ufw).
|
1 2 3 |
http://server_domain_or_address_IP |
MySQL installation
Then, you need to install MySQL via the following command :
|
1 2 3 |
apt-get install mysql-server |
During the installation, you will be asked to choose a password root.
It is advisable to carefully choose your password preferably alphanumerical and including special characters.
To proceed with the installation, the following command has to be executed :
|
1 2 3 |
mysql_secure_installation |
Enter your password root when requested and confirm the four following questions with yes :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
Enter current password for root (enter for none): OK, successfully used password, moving on... Remove anonymous users? [Y/n] <strong style="color: orange;">y</strong> ... Success! Disallow root login remotely? [Y/n] <strong style="color: orange;">y</strong> ... Success! Remove test database and access to it? [Y/n] <strong style="color: orange;">y</strong> - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reload privilege tables now? [Y/n] <strong style="color: orange;">y</strong> ... Success! Cleaning up... |
PHP installation
Since Nginx does not contain PHP natively, it is important to install the PHP process manager called PHP FPM (FastCGI Process Manager) :
|
1 2 3 |
sudo apt-get install php5-fpm php5-mysql |
Then, we are going to change the PHP configuration by changing the cgi.fix_pathinfo variable value to 1 or simply un-comment the line :
|
1 2 3 4 5 |
vim /etc/php5/fpm/php.ini cgi.fix_pathinfo=1 |
Finally, we restart the PHP service :
|
1 2 3 |
systemctl restart php5-fpm |
Nginx configuration
Now, we are going to change our default vhost so that Nginx uses the PHP processor :
|
1 2 3 |
vim /etc/nginx/sites-available/default |
The red elements need to be added to the default vhost file :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
server { listen 80 default_server; listen [::]:80 default_server; root /var/www/html; index <span style="color: #ff0000;">index.php</span> index.html index.htm index.nginx-debian.html; server_name <span style="color: #ff0000;">server_domain_or_address_IP</span>; location / { try_files $uri $uri/ =404; } <span style="color: #ff0000;">location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass unix:/var/run/php5-fpm.sock; } location ~ /\.ht { deny all; }</span> } |
Now, we need to check the Nginx configuration then reload the service and in case of error, we would have to review the previous configured file :
|
1 2 3 4 5 |
nginx -t nginx -s reload |
Use
To conclude, we are going to test pour LEMP server with a page phpinfo :
|
1 2 3 |
echo "<php phpinfo(); >" > /var/www/html/phpinfo.php |
The result is available from the url http://server_domain_or_address_IP/phpinfo.php and it leads to the following result :
From now on, your LEMP server is operational and will allow you performance enhancements, especially in terms of requests number compared to a LAMP server on Apache.
