通过CGI实现在Html页面上执行shell命令

在mac上配置cgi(不用系统自带的apache cgi.)

安装cgi

1. brew update

2. brew install httpd24

　　

安装完后，会有如下提示

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

打开apache

3. brew services start httpd

　　

在浏览器输入

brew安装的apache默认端口是8080，mac自带的apache默认端口是80

修改httpd.conf文件

添加两行：

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

修改 <Directory "/usr/local/var/www/cgi-bin">标签里的内容如下，ExecCGI 表示在cgi-bin目录下执行cgi脚本，所有的cgi脚本都需要放到改目录下。
<Directory "/usr/local/var/www/cgi-bin">
    Options ExecCGI
    AllowOverride None
    Order deny,allow
    Allow from all
</Directory>

取消下面三行的注释：
AddHandler cgi-script .cgi
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml

在AddHandler cgi-script .cgi 后面添加支持的cgi脚本格式， 比如.sh .pl. 由于我这里用shell脚本，所有修改为
AddHandler cgi-script .cgi .sh

修改权限

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

重启服务器

brew services restart httpd

　　

在 /usr/local/var/www/cgi-bin 下放置测试脚本delete.sh

#!/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!"
fi

　　需要给delete.sh 权限

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

　　在浏览器中打开

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

　　或者用curl

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