A.5 Disable and remove  httpd (Apache) server if  installed , Start Nginx HTTP server and PHP-FPM (FastCGI Process Manager)

Stop httpd (Apache)

## Fedora 28/29 and CentOS/RHEL 7.6 ##
systemctl stop httpd.service
systemctl disable httpd.service

## CentOS/RHEL 6.10 ##
service httpd stop
chkconfig httpd off

Start Nginx

## Fedora 28/29 and CentOS/RHEL 7.6 ##
systemctl start nginx.service

## CentOS/RHEL 6.10 ##
service nginx start

Start PHP-FPM

## Fedora 28/29 and CentOS/RHEL 7.5 ##
systemctl start php-fpm.service

## CentOS/RHEL 6.10 ##
/etc/init.d/php-fpm start ## use restart after update
## OR ##
service php-fpm start ## use restart after update

1.6 Autostart Nginx and PHP-FPM on boot, also prevent httpd (Apache) autostarting on boot
Prevent httpd (Apache) autostarting on boot

Autostart Nginx on boot

## Fedora 28/29 and CentOS/RHEL 7.6
systemctl enable nginx.service

## CentOS/RHEL 6.10 ##
chkconfig --add nginx
chkconfig --levels 235 nginx on

Autostart PHP-FPM on boot

## Fedora 28/9 and CentOS/RHEL 7.6
systemctl enable php-fpm.service

## CentOS/RHEL 6.10 ##
chkconfig --add php-fpm
chkconfig --levels 235 php-fpm on

A.7 Configure Nginx and PHP-FPM
Latest Fedora Nginx + PHP-FPM builds use custom config, first restore default config

Restore nginx  configs to default

cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak
vi /etc/nginx/nginx.conf

This is how my nginx conf file look like

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;


events {
worker_connections 1024;
}


http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
#tcp_nopush on;

keepalive_timeout 65;
#gzip on;

include /etc/nginx/conf.d/*.conf;
}

Modify PHP-FPM to listen ip instead of socket ##
vi /etc/php-fpm.d/www.conf

## Change following   Lines##
;listen = /run/php-fpm/www.sock
listen = 127.0.0.1:9000

public_html directory  for site Osradar.local

mkdir -p /var/www/osradar.local

chown -R nginx:nginx /var/www/osradar.local

add logs under /var/log directory.

## public_html directory and logs directory ##
mkdir -p /var/www/osradar.local/
chown -R nginx:nginx /var/www/osradar.local
chown -R nginx:nginx /var/log/nginx

my  Vhost Configuration File

cat  /etc/nginx/conf.d/osradar.local.conf

server {
    listen         80 default_server;
    listen         [::]:80 default_server;
    server_name     osradar.local;
    root           /var/www/osradar.local;
    index          index.html index.php;

    location / {
      try_files $uri $uri/ =404;
    }

    location ~* \.php$ {
      fastcgi_pass 127.0.0.1:9000;
      include         fastcgi_params;
      fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
      fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
    }
}

Start  Nginx

Fedora 28/29 and CentOS/RHEL 7.6 ##
systemctl restart nginx.service 


## CentOS/RHEL 6.10 ##
service nginx restart

Add your testsite.local “domain” to /etc/hosts file

/etc/hosts file Nginx on same machine

127.0.0.1 localhost.localdomain localhost 
192.168.2.98 osradar.local

A.8 Test your Nginx and PHP-FPM setup

Create /var/www/osradar.local/test.php file with following content:

 <?php phpinfo(); ?>

Note:
If you get 403 forbidden error, then you probably have problem with SELinux, then run simply following command:

chcon -R -t httpd_sys_content_t /var/www/osradar.local/

## Or some apps might need httpd_sys_rw_content_t ##

chcon -R -t httpd_sys_rw_content_t /var/www/osradar.local/

B.0  (Open Port 80 on Iptables Firewall)

vi /etc/sysconfig/iptables

Add following INPUT rule:

-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

B.1 Restart Iptables Firewall:

service iptables restart

B.2. Fedora 28/29 and CentOS/Red Hat (RHEL) 7.6

B.2.1 Add New http Rule to Firewalld

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

B.2.2 Restart firewalld.service

systemctl restart firewalld.service

3. Test remote connection

Access following address, with your browser. http://osradar.local/

note: i have already crated index.html with the text showing bellow on /var/www/osradar.local/index.html

Test PHP   conf file http://osradar.local/test.php
