موارد مرتبط با خطای اسکریپت cgi - Premature End of Script Headers

Premature end of script headers’ can be an extremely vague error that leads to some headaches. Here are some suggestions that might help you fix the problem.

 

Sometimes when executing a script you will see an error similar to the following:

Premature end of script headers: /home/directory/public_html/index.php

This error occurs because the server is expecting a complete set of HTTP headers (one or more followed by a blank line), and it doesn’t get them. This can be caused by several things:

1. Upgrading or downgrading to a different version of PHP can leave residual options in the httpd.conf. Check the current version of PHP using php -v on the command line and search for any lines mentioning another version in the httpd.conf. If you find them, comment them out, distill the httpd.conf and restart apache.

2. The RLimitCPU and RLimitMEM directives in the httpd.conf may also be responsible for the error if a script was killed due to a resource limit.

3. A configuration problem in suEXEC, mod_perl, or another third party module can often interfere with the execution of scripts and cause the error. If these are the cause, additional information relating to specifics will be found in the apache error_log.

4. If suphp’s log reaches 2GB in size or larger you may see the premature end of scripts headers error. See what the log contains and either gzip it or null it. Restart apache and then deal with any issues that the suphp log brought to light. The suphp log is located at: /usr/local/apache/logs/suphp_log

5. The script’s permissions may also cause this error. CGI scripts can only access resources allowed for the User and Group specified in the httpd.conf. In this case, the error may simply be pointing out that an unauthorized user is attempting to access a script.

6-also check that the HDD partition that the file is in it , is not mounted with noexec permissions : 
for exmaple an output of a noexec mount : 
/tmp type ext3 (rw,noexec,nosuid,loop=/dev/loop0)

7-also check the permission of the cgi scripts being 755 , and add the following line to the htaccess of that directory :

Addhandler  cgi-script .py .pl .cgi
