Guide for Nginx/PHP on CentOS 7
Step 1 — Install Nginx
Install the EPEL repository for additional packages like Nginx,
yum install epel-release
Now install Nginx,
yum install nginx
Start Nginx,
systemctl start nginx
Set Nginx to start on boot:
systemctl enable nginx
Step 2 — Install PHP
Install the php, php-mysql and php-fpm packages
yum install php php-mysql php-fpm
Configure the PHP Processor:
Edit the php-fpm config file,
nano /etc/php.ini
Uncomment the line and change it to 0:
cgi.fix_pathinfo=0
Next, edit the php-fpm config www.conf:
nano /etc/php-fpm.d/www.conf
Find the the listen parameter line, and change it so it looks like this:
listen = /var/run/php-fpm/php-fpm.sock
Next, find the lines "listen.owner and listen.group" and uncomment them. They should look like this:
listen.owner = nobody
listen.group = nobody
Lastly, find the lines that set the user and group and change their values from “apache” to “nginx”:
user = nginx
group = nginx
Then save and quit. Now, we just need to start our PHP processor by typing:
systemctl start php-fpm
Next, set php-fpm to start on boot:
systemctl enable php-fpm
Step 3 — Configure Nginx to Process PHP Pages
Edit the file,
nano /etc/nginx/conf.d/default.conf
Make the changes as seen below,
server {
listen 80;
server_name server_domain_name_or_IP;
# note that these lines are originally from the "location /" block
root /usr/share/nginx/html;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
Restart Nginx to reload the configuration changes
systemctl restart nginx
Step 4 — Test PHP Processing on your Web Server
In order for Nginx to find the file and serve it correctly, it must be saved to the "web root". Which can be found at the following path on CentOS 7,
/usr/share/nginx/html/
To create the file at that location:
nano /usr/share/nginx/html/info.php
We want to put the valid PHP code, inside the blank file:
<?php phpinfo(); ?>
After this, save and close the file.
Visit the following page in your web-browser to verify that PHP processing works, Replace "your_server_IP_address" with your VMs actual IP address,
http://your_server_IP_address/info.php
