step1下载：

ftp://ftp.gnu.org/gnu/cgicc/

step2:

tar xzf cgicc-X.X.X.tar.gz(用最新版本)

cd cgicc-X.X.X

./configure --prefix=/usr

/var/www/html/testcgi.html:

备注：

我虚拟机环境需要开通防火墙：

iptables -I INPUT 4 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

The following paths are for a Red Hat 7.x installation.

Place web page in: /var/www/html/testcgi.html
Place cgi in: /var/www/cgi-bin/testcgi
Start Apache: service httpd start
Test: http://localhost/testcgi.html
