Due to the frequent need to execute some commands on the server, some commands are too lazy to knock, ready to write a script direct browser calls, such as:
Because there is a ready-made Apache on the line, just put it inside, of course, access security to set, I seem to write the other essays on security issues, here do not write.

When configured, use the browser to access:
Because before the directory is not under the WWW, but/var/www/html/cgi-bin/, so suspicion suexec:
however , the change to/var/www/cgi-bin/still does not, and suEXEC also wood has error log , see Apache error log:
Since there is a second sentence, that can not find the file should not be aaa.py found, so I directly executed the PY script:
This is obvious, this python behind a little more things, this is obviously coding problems, vim into the aaa.py, with: Set FF looked at, originally because this script is created on Windows, so the format is Fileformat=dos, with: Set ff= UNIX to change the file format and then save it.
