This is one of the most crucial part, you need to move the processwire directory onto nginx document root. Do it this way.

[root@linuxhelp ~]# mv processwire-master/ 
/usr/share/nginx/html/

After that, you need to provide owner permission and file execution permission as follows.

[root@linuxhelp ~]# chown -R nginx:nginx 
/usr/share/nginx/html/
[root@linuxhelp ~]# chmod -R 775 /usr/share/nginx/html/

Another crucial step in this installation process is the configuration of nginx, for that you need to access the .conf file. Run the following command for the same purpose.

[root@linuxhelp ~]# vim /etc/nginx/nginx.conf

Once the .conf file is open, configure it as follows.

server {
        listen       80 default_server 
        listen       [::]:80 default_server 
        server_name  192.168.7.165 
        root         /usr/share/nginx/html 
        index index.php 

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf 

        location  ~ \.php$ {
        try_files $uri =404 
        fastcgi_pass unix:/run/php-fpm/php-fpm.sock 
        fastcgi_index index.php 
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name 
        include fastcgi_params 
        }
    }

After the configuration, restart your nginx service with the help of the following command.

[root@linuxhelp ~]# systemctl restart nginx

The configuration part doesn' t end with this as you should also make some changes in the php-fpm configuration file. Run the following command to open that file.

[root@linuxhelp ~]# vim /etc/php-fpm.d/www.conf. 

Once the file is open, make the following changes.

listen = /run/php-fpm/php-fpm.sock
listen.owner = nginx
listen.group = nginx

user = nginx
group = nginx

After configuring the file, you need to start the php fpm service so run the following command for the same purpose.

[root@linuxhelp ~]# systemctl start php-fpm

The configuration part is over, but you still need to provide owner permission for php-fpm configuration. This can be done by running the following command.

[root@linuxhelp ~]# chown -R nginx:nginx /run/php-fpm/php-
fpm.sock 

After all this, you need to restart php-fpm service as follows.

[root@linuxhelp ~]# systemctl restart php-fpm

Now let us do the remaining part through GUI, so switch to your browser and enter machine’ s IP address in the URL search bar. When the page appears, click on the Get Started button.

Now, in the Site Installation Profile drop-down list box, choose Default (Beginner Edition).

Once the details appear on your screen, click on Continue to proceed further.

Once the Compatibility Check appears, check all the listed details and then click on Continue at the end of that page.

Now, you will be asked to enter your Database credentials, so enter all the details in the appropriate fields, and then click on Continue for proceeding further.

You will be acknowledged about your Admin Account. Then scroll down to enter your Admin Panel Information.

Enter all the necessary details and click on Continue.

After that, you' ll get to see your minimal site profile. You can enhance it by adding your web content.

With this, the installation of ProcessWire CMS on CentOS 7 via NGINX is complete.
