Best Advantage for NGINX

NGINX also has a rich set of features and can perform various server roles:

 

1 - A reverse proxy server for the HTTP, HTTPS, SMTP, POP3, and IMAP protocol

2 - A load balancer and an HTTP cache

3 - A frontend proxy for Apache and other web servers, combining the flexibility of Apache with the good static content performance of NGINX

NGINX supports FastCGI and SCGI handlers for serving dynamic content scripts such as PHP and Python. It uses the LEMP stack: a variation of LAMP using the phonetic spelling of NGINX (Linux, “En-juhn-ex,” MySQL, PHP).

Therefore to install Nginx the following command you can see blow....

 Installation of Ngnix

 To add the CentOS 7 EPEL repository

        yum install epel-release

Install Nginx

yum install nginx

Start Nginx

systemctl start nginx

Allow from firewall

firewall-cmd --permanent --zone=public --add-service=http

firewall-cmd --permanent --zone=public --add-service=https

firewall-cmd  --reload

enable Nginx to start when your system boots

        systemctl enable nginx

default server root directory is

        /usr/share/nginx/html

Configuration

                /etc/nginx/nginx.conf       

 

Installation of PHP

To add his PHP repository, run the following command

yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

This pulls in the package and adds the repository to YUM. It is being added disabled, though, so we have to enable that manually. So, open the repository file:
vi /etc/yum.repos.d/remi.repo

cut out the ‘remi-php55’ and ‘remi-php56’  block as we want PHP 7.0. 

vi /etc/yum.repos.d/remi-php70.repo

To enable repository, you have to change ‘enabled=0’ into ‘enabled=1’.

yum install php-fpm php-cli php-common php-mbstring php-gd php-intl php-xml php-mysql php-mcrypt php-zip php-curl
php –v

 To ensure it also starts automatically with the server, run

        systemctl enable php-fpm

To find a file

        find / -name php-fpm.conf

 Change both the user and the group to nginx

        vi /etc/php-fpm.d/www.conf

/etc/nginx/nginx.conf

add the following content to it:

        location ~\.php$ {

             try_files $uri =404;

             fastcgi_pass   127.0.0.1:9000;

             fastcgi_index  index.php;

       fastcgi_param SCRIPT_FILENAME                  

       $document_root$fastcgi_script_name;

             include fastcgi_params;

       }

 Restart nginx

        systemctl stop nginx

        systemctl start nginx

Restart php-fpm

        systemctl status php-fpm.service

        systemctl stop php-fpm.service

        systemctl start php-fpm.service

NginX has been marked to record high performance than Apache. NginX require very less memory as far more clients 

can be supported with minimum or no thread. Hence very little memory is utilized as compared to Apache which needs 

one thread/process or each client.
