求助cgi

gary4096

大侠们好，

我有一个cgi程序几乎天天在用，但已经好几年没有改动了。今天改了一个小地方后，就突然不跑了。现在改回原来的码也没用。 返回的web页面是空白，
error log 是：

[..2014] [error] [client...] (2)No such file or directory: exec of '/home/coflo/cgi/gb/adm/source_ctl.cgi' failed
[..2014] [error] [client...] Premature end of script headers: source_ctl.cgi

请问这会是什么造成的？

谢谢

第一行说明少了文件.

你不会是在 Windows下改的吧? 试着 dos2unix 一看看. 有时候perl 脚本的第一行 如果后面 多了 '^M' (vi下查看), 是不能正常执行的.

谢谢大侠，
确实我是在windows xp底下编辑的，但是我上传时都会把\r去掉，
刚刚我用binary mode 打开查看，第一行
#!/usr/bin/perl
确实没有\r
但是还是不行，出来是空白页。
继续求助。。。

直接在命令行执行一下这个脚本看看, 如果脚本本身有问题, 会直接把错误打出来的. 或者至少它应该把 header 打出来

谢谢指导，

直接在命令行执行一下这个脚本就直接打出了html,没问参数，没报错。
还是不知道问题所在。。。

谷歌搜寻，找到了下面：
suEXEC Problems
...and how to fix them.

When running a Perl CGI script, you may see the "premature end of script headers" error in your Apache error.log or error_log file.  This can be caused by some of the same problems (and fixed with some of the same fixes) as the Internal Server Error message.  However, this can also be caused by suEXEC errors, and in that case, it may give you no indication whatsoever that suEXEC is the cause.

Check if you have a /var/log/apache/suexec.log file; if so, and if it's the problem, it'll explain the reason why it's denying your script from executing properly.  One easy fix to try is adding a "-w" to the end of the first line of your Perl script, i.e. change the first line from "#!/usr/bin/perl" to "#!/usr/bin/perl -w" and see if that makes suEXEC happy.  Another common fix is to make sure that your CGI script has the same user/group ownership as your cgi-bin folder.

我把第一行加改为：
#!/usr/bin/perl -w

问题解决了，也十分感谢 q1208c 大侠！
