Test nginxOpen up your web browser and navigate to http://ip-address/ or http://localhost/ .You will see a screen something like below.

Configure NginxOpen the file /etc/nginx/nginx.conf in any editor:

sudo nano /etc/nginx/nginx.conf

Set the worker_processes (i.e No. of CPU’s in your system). To see the no. of CPU’s,use the command “lscpu” . In my case it’s “1″. So I set this as ’1′.

worker_processes 1;

Restart Nginx service:

sudo service nginx restart

The default vhost(server block) is defined in the /etc/nginx/sites-available/default file.

Open the file /etc/nginx/sites-available/default in any editor.

sudo nano /etc/nginx/sites-available/default

Under the Server section, set the server FQDN or IP address as shown below.

[...]

server {

listen 80 default_server;

listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html;index index.php index.html index.htm;

# Make site accessible from http://localhost/

server_name server.unixmen.local ;

[...]

Make sure you’ve added index.php line.

Here,

listen 80; – > listen for ipv4 listen [::]:80 default_server ipv6only=on; – > listen for ipv6 root /usr/share/nginx/html; – > document root directory. server_name server.unixmen.local ; – > Server FQDN.

Now scroll down further and find the section #location ~ \.php$ . Uncomment and modifythe following lines as shown below.

location ~ \.php$ {

try_files $uri =404; ---------> Add this line

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;

include fastcgi_params;

}

Here, I added an extra line ‘try_files $uri =404;’ to prevent zero day exploits.

Save and exit the file.

Test nginx configurationTest the nginx configuration for any syntax errors using command:

sudo nginx -t

Sample output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

Finally restart nginx service

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db

sudo add-apt-repository 'deb http://mirrors.scie.in/mariadb/repo/5.5/ubuntu trusty main'

Update the software sources list and install MariaDB using following commands:

sudo apt-get update

sudo apt-get install mariadb-server mariadb-client -y

During installation you will be asked to set database ‘root’ user p assword.

Find the line ‘cgi.fix_pathinfo=1′ , uncomment it and change the value 1 to 0 .

cgi.fix_pathinfo=0

PHP-FPM listens on the socket /var/run/php5-fpm.sock by default. If you want tomake PHP-FPM use a TCP connection, open the file /etc/php5/fpm/pool.d/www.conf,

sudo nano /etc/php5/fpm/pool.d/www.conf

Find the line listen = /var/run/php5-fpm.sock ,

;listen = /var/run/php5-fpm.sock

and modify it to listen = 127.0.0.1:9000 .

listen = 127.0.0.1:9000

Save and exit the file. Restart php5-fpm service.

sudo service php5-fpm restart

Now open the nginx configuration file:

sudo nano /etc/nginx/sites-available/default

http://180016988.r.cdn77.net/wp-content/uploads/2014/06/phpinfo-Mozilla-Firefox_006.png


13/18



Find the line fastcgi_pass unix:/var/run/php5-fpm.sock; and change itto fastcgi_pass 127.0.0.1:9000; as shown below.

location ~ \.php$ {

try_files $uri =404;fastcgi_split_path_info ̂ (.+\.php)(/.+)$;

# # 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;

include fastcgi_params;

}

Save and exit the file. Finally restart nginx service.

Manage MySQL Databases UsingphpMyAdmin (Optional)phpMyAdmin is a free open-source web interface tool used to manage your MySQLdatabases.

Install phpMyAdminIt is available in the Official Debian repositories. So install it with command:

sudo apt-get install phpmyadmin

Select any webserver. By default, nginx will not be displayed here. So, select apache orlighttpd and let us link phpmyadmin to work with nginx webserver later.



15/18



Select Yes to configure database for phpmyadmin with dbconfig-common .

Enter password of the database’s administrative user.



16/18



Enter MySQL application password phpmyadmin.

Re-enter the password.



17/18



The phpMyAdmin installation has been completed.

Create a symbolic link between phpMyAdmin and the website root directory. Here ourwebsite root document directory is /usr/share/nginx/html/ .

sudo ln -s /usr/share/phpmyadmin/ /usr/share/nginx/html

Restart nginx server.


Access phpMyAdmin Web ConsoleNow you can access the phpmyadmin console by navigating to http://server-ip-address/phpmyadmin/ from your browser.

Enter your MySQL username and password which you have given in previous steps. Inmy case its “root” and “ubuntu”.

You will be redirected to PhpMyAdmin main web interface.
