The author's nginx installation directory is/usr/local/nginx virtual machine configuration file/usr/local/nginx/conf/vhosts. conf phpfast-cgi currently supports the following operations to install the perlcgi module wgethttp: // www.cpan.org/modules/by-module/FC in su:

The installation directory of nginx is/usr/local/nginx.

The virtual machine configuration file is/usr/local/nginx/conf/vhosts. conf.

Currently, php fast-cgi supports

The following operations are completed under su:

==================================

Install the perl cgi module
Wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.67.tar.gz

Tar-zxvf FCGI-0.67.tar.gz
Cd FCGI-0.67
Perl Makefile. PL
Make & make install

Install FCGI-ProcManager:
Wget http://search.cpan.org/CPAN/authors/id/G/GB/GBJK/FCGI-ProcManager-0.18.tar.gz
Tar-xzxf FCGI-ProcManager-0.18.tar.gz
Cd FCGI-ProcManager-0.18
Perl Makefile. PL
Make install
==============================

First, place a perl-written distributor in the/bin directory named perl-fcgi.
