FastCGI is a protocol for interfacing interactive programs with a web server. It is a variation of the earlier Common Gateway Interface (CGI) but offers significant performance improvements. Here are the key points about FastCGI:
FastCGI is widely used to enhance the performance of web applications, particularly those requiring dynamic content generation. Its efficiency and flexibility make it a popular choice for many web developers and system administrators.

We have provisioned a CentOS 7 minimal install virtual machine with following specifications.
Connect with nginx-01.example.com using ssh as root user.
Nginx is not available in standard yum repositories, therefore, we are installing EPEL (Extra Packages for Enterprise Linux) yum repository.
# yum install -y epel-release
Build cache for EPEL yum repository.
# yum makecache fast Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile epel/x86_64/metalink | 6.9 kB 00:00 * base: mirrors.ges.net.pk * epel: my.fedora.ipserverone.com * extras: mirrors.ges.net.pk * updates: mirrors.ges.net.pk base | 3.6 kB 00:00 epel | 5.4 kB 00:00 extras | 3.4 kB 00:00 updates | 3.4 kB 00:00 (1/3): epel/x86_64/group_gz | 88 kB 00:03 (2/3): epel/x86_64/updateinfo | 998 kB 00:07 (3/3): epel/x86_64/primary_db | 6.8 MB 01:07 Metadata Cache Created
Install Nginx web server using yum command.
# yum install -y nginx
Enable and start nginx service.
# systemctl enable --now nginx.service Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
Allow HTTP service in Linux firewall.
# firewall-cmd --permanent --add-service=http success # firewall-cmd --reload success
Browse URL http://nginx-01.example.com using a client’s browser.
Nginx web server has been installed on CentOS 7.
Unlike Apache HTTP Server, Nginx do not spawn FastCGI processes. Therefore, we required to install spawn-fcgi to process Perl scripts.
# yum install -y spawn-fcgi
Now install fcgiwrap package using yum command.
# yum install -y fcgiwrap
Edit spawn-fcgi configuration file.
# vi /etc/sysconfig/spawn-fcgi
and add following line therein.
OPTIONS="-u nginx -g nginx -a 127.0.0.1 -p 9001 -P /var/run/spawn-fcgi.pid -- /usr/sbin/fcgiwrap"
Enable and start spawn-fcgi service.
# systemctl enable --now spawn-fcgi spawn-fcgi.service is not a native service, redirecting to /sbin/chkconfig. Executing /sbin/chkconfig spawn-fcgi on
Create a directory as Nginx document root.
# mkdir /var/www
Create a sample Perl script in Nginx document root directory.
# vi /usr/share/nginx/html/index.cgi
and add following lines of code.
#!/usr/bin/perl print "Content-type: text/htmlnn"; print "<html><body><h1>Hello World!"; print "</h1></body></html>n";
Adjust file permissions for index.cgi.
# chmod +x /usr/share/nginx/html/index.cgi
Add our Nginx server configuration file as follows.
# vi /etc/nginx/default.d/default.conf
and add following directive therein.
index index.cgi; location ~* .(pl|cgi)$ { gzip off; include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9001; fastcgi_index index.cgi; }
Restart nginx service.
# systemctl restart nginx
Set SELinux boolean, so the Nginx can communicate to spawn-fcgi.
# setsebool -P httpd_can_network_connect on
Browse URL http://nginx-01.example.com/ in a client’s browser.
Our Perl script has been executed successfully. We have successfully configure FastCGI Server using Nginx on CentOS 7.
