Execute shell commands on Html pages through CGI

Configure cgi on mac (without the apache cgi that comes with the system.)

install cgi

1. brew update

2. brew install httpd24

　　

After installation, the following prompt will appear

DocumentRoot is /usr/local/var/www.

The default ports have been set in /usr/local/etc/httpd/httpd.conf to 8080 and in
/usr/local/etc/httpd/extra/httpd-ssl.conf to 8443 so that httpd can run without sudo.

To have launchd start httpd now and restart at login:
brew services start httpd
Or, if you don't want/need a background service you can just run:
apachectl start

open apache

3. brew services start httpd

　　

Type in the browser

localhost:8080

　　

If you get It'works, it means apache runs successfully

The default port of apache installed by brew is 8080, and the default port of apache that comes with mac is 80

 

Modify the httpd.conf file

Add two lines:

LoadModule cgi_module lib/httpd/modules/mod_cgi.so
LoadModule cgid_module lib/httpd/modules/mod_cgid.so

Modify the contents of the <Directory "/usr/local/var/www/cgi-bin"> tag as follows, ExecCGI means to execute cgi scripts in the cgi-bin directory, and all cgi scripts need to be placed in the modified directory.
<Directory "/usr/local/var/www/cgi-bin">
    Options ExecCGI  
    AllowOverride None  
    Order deny,allow  
    Allow from all
</Directory>

Uncomment the following three lines:
AddHandler cgi-script .cgi
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml

Add a supported cgi script format after AddHandler cgi-script .cgi, such as .sh .pl. Since I use shell script here, all modifications are
AddHandler cgi-script .cgi .sh

 

edit permission

chmod +x /usr/local/var/www
chmod +x /usr/local/var/www/cgi-bin

restart the server

brew services restart httpd

　　

Put the test script delete.sh under /usr/local/var/www/cgi-bin

#!/bin/bash
echo "Content-type: text/html"
echo ""

# ok, we've sent the header, now send some content
rm -f $QUERY_STRING
if [ "$?" -eq 0 ]; then
  echo "Deleted!"
else
  echo "Delete failed!"
be

　　Need to give delete.sh permission

chmod +x /usr/local/var/www/cgi-bin/delete.sh
　

　　open in browser

localhost:8080/cgi-bin/delete.sh?1.png

　　or with curl

curl "localhost:8080/cgi-bin/delete.sh?1.png"
