By | November 21, 2015

LEMP stacks are an open source platform for web applications consisting of Linux, Nginx, MySQL or MariaDB, and PHP or another language such as Python.

L – Linux
E – Nginx (Pronounced Engine-X)
M – MySQL
P – PHP

Step 1 Log in to your Linux server with the root user. This has taken care of the ‘L’ of LEMP.

Step 2 Next we will update all the softwares to the latest versions

sibanda@gs2:~# sudo apt-get update

Step 3 Install MySQL on the server with the following command :

sibanda@gs2:~# sudo apt-get install mysql-server php5-mysql

You would be prompted to enter a password for your MySQL.

Once the installation is complete activate it using the following command :

sibanda@gs2:~# sudo mysql_install_db

Next run the MySQL set up script :

sibanda@gs2:~# sudo /usr/bin/mysql_secure_installation

You will be prompted to enter your password. Then you will be asked to change the root password, type N and move on. For the rest of the options chose ‘Y’.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL 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, MySQL 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
 ... Success!



Cleaning up...

Step 4 Install PHP

sibanda@gs2:~# sudo apt-get install php5-fpm

Open www.conf file

sibanda@gs2:~# sudo vi /etc/php5/fpm/pool.d/www.conf

Find the line

;listen = /var/run/php5-fpm.sock
; listen = 127.0.0.1:9000

and change it to

listen = /var/run/php5-fpm.sock
Save the file and exit and restart php-fpm :

sibanda@gs2:~# sudo service php5-fpm restart

Step 5 Install nginx

sibanda@gs2:~# echo "deb http://ppa.launchpad.net/nginx/stable/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/nginx-stable.list
sibanda@gs2:~# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C300EE8C
sibanda@gs2:~# sudo apt-get update && sudo apt-get install nginx

You need to start nginx by typing :

sibanda@gs2:~# sudo service nginx start

Step 6 Copy the default config file for Nginx

sibanda@gs2:~# sudo cp -rf /etc/nginx/sites-available/default /etc/nginx/sites-available/magwinya.co.za

I normally delete the default nginx server block to avoid “conflicting server name” error.

sibanda@gs2:~# sudo rm -rf /etc/nginx/sites-available/default

Step 7 Open the copied config file for Nginx

sibanda@gs2:~# sudo vi /etc/nginx/sites-available/magwinya.co.za

The Server block for the config file should have the following settings

# You may add here your
# server {
#       ...
# }
# statements for each of your virtual hosts to this file

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

# Server Block Configuration for www.magwinya.co.za
server {
        listen 80;
#       listen [::]:80 default_server ipv6only=on;

        root /home/mwired/public_html;
        index index.php index.html index.htm;

        # Make site accessible from http://localhost/
        server_name magwinya.co.za www.magwinya.co.za;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ /index.php?q=$uri&$args;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules
        }

        location /doc/ {
                alias /usr/share/doc/;
                autoindex on;
                allow 127.0.0.1;
                allow ::1;
                deny all;
        }

        # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
        #location /RequestDenied {
        #       proxy_pass http://127.0.0.1:8080;
        #}

        error_page 404 /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
                root /usr/share/nginx/html;
        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
        #       fastcgi_split_path_info ^(.+\.php)(/.+)$;
        #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        #       # With php5-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php5-fpm:
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        location ~ /\.ht/ {
                deny all;
        }
}


# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#       listen 8000;
#       listen somename:8080;
#       server_name somename alias another.alias;
#       root html;
#       index index.html index.htm;
#
#       location / {
#               try_files $uri $uri/ =404;
#       }
#}


# HTTPS server
#
#server {
#       listen 443;
#       server_name localhost;
#
#       root html;
#       index index.html index.htm;
#
#       ssl on;
#       ssl_certificate cert.pem;
#       ssl_certificate_key cert.key;
#
#       ssl_session_timeout 5m;
#
#       ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
#       ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES";
#       ssl_prefer_server_ciphers on;
#
#       location / {
#               try_files $uri $uri/ =404;
#       }
#}

Step 8

sibanda@gs2:~# sudo cp /etc/nginx/sites-available/magwinya.co.za /etc/nginx/sites-enabled/

Alternatively, you can activate the host by creating a symbolic link between the sites-available directory and the sites-enabled directory.

sibanda@gs2:~# sudo ln -s /etc/nginx/sites-available/magwinya.co.za /etc/nginx/sites-enabled/magwinya.co.za

Important: Restart php-fpm and nginx so that changes can take effect.

sudo service php5-fpm restart && service nginx restart
