Find to install NGINX on Centos

Install nginx
Pre-Requirements:
1.Install MySQL
2.Install Php

Install dependencies for nginx

yum -y install gcc gcc-c++ make zlib-devel pcre-devel openssl-devel

 we will install nginx on our virtual private server using yum:
sudo yum install nginx

nginx does not start on its own. To get nginx running, type:
sudo /etc/init.d/nginx start

You can confirm that nginx has installed on your virtual private server by directing your browser to your IP address. You can run the following command to reveal your server’s IP address.
ifconfig eth0 | grep inet | awk '{ print $2 }'

Install PHP
The php-fpm package is located within the REMI repository, which, at this point, is disabled. The first thing we need to do is enable the REMI repository and install php and php-fpm:
sudo yum --enablerepo=remi install php-fpm php-mysql

Configure php
We need to make one small change in the php configuration. Open up php.ini:
 sudo vi /etc/php.ini

Find the line, cgi.fix_pathinfo=1, and change the 1 to 0.
cgi.fix_pathinfo=0

If this number is kept as a 1, the php interpreter will do its best to process the file that is as near to the requested file as possible. This is a possible security risk. If this number is set to 0, conversely, the interpreter will only process the exact file path—a much safer alternative. Save and Exit.

Configure nginx
Open up the default nginx config file:
sudo vi /etc/nginx/nginx.conf

Raise the number of worker processes to 4 then save and exit that file.

Now we should configure the nginx virtual hosts. In order to make the default nginx file more concise, the virtual host details are in a different location.
sudo vi /etc/nginx/conf.d/default.conf

The configuration should include the changes below (the details of the changes are under the config information):
#
# The default server
#
server {
    listen       80;
    server_name example.com;

  
    location / {
        root   /usr/share/nginx/html;
        index index.php  index.html index.htm;
    }

    error_page  404              /404.html;
    location = /404.html {
        root   /usr/share/nginx/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$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}


Here are the details of the changes:
Add index.php within the index line.

Change the server_name to your domain name or IP address (replace the example.com in the configuration)

Change the root to /usr/share/nginx/html;

Uncomment the section beginning with "location ~ \.php$ {",

Change the root to access the actual document root, /usr/share/nginx/html;

Change the fastcgi_param line to help the PHP interpreter find the PHP script that we stored in the document root home.

Save and Exit

Open up the php-fpm configuration:
sudo vi /etc/php-fpm.d/www.conf

Replace the apache in the user and group with nginx:
[...]
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;    will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx
[...]

Finish by restarting php-fpm.
sudo service php-fpm restart

Step Seven—RESULTS: Create a php info page
Although LEMP is installed, we can still take a look and see the components online by creating a quick php info page

To set this up, first create a new file:
sudo vi /usr/share/nginx/html/info.php

Add in the following line:
<?php
phpinfo();
?>

Then Save and Exit.

Restart nginx so that all of the changes take effect:
sudo service nginx restart

Finish up by visiting your php info page (make sure you replace the example ip address with your correct one): http://IPAddress/info.php

It should look similar to this.

Set Up Autostart
You are almost done. The last step is to set all of the newly installed programs to automatically begin when the VPS boots.
sudo chkconfig --levels 235 mysqld on
sudo chkconfig --levels 235 nginx on
sudo chkconfig --levels 235 php-fpm on
