所以我检查了一下我的剧本

perl -cw /var/www/cgi/env.pl
var/www/cgi/env.pl syntax OK

我在命令行中仔细检查它。它工作并向我显示我的环境值。
我的/etc/apache2/sites-available/mysite.com看起来像这样：
服务器管理网站管理员@本地主机服务器名mysite.com

DocumentRoot /var/www
<Directory />
    Options FollowSymLinks +ExecCGI
    AllowOverride None
    AddHandler cgi-script .cgi .pl
</Directory>
<Directory /var/www/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

ScriptAlias /cgi-bin/ /var/www/cgi/

<Directory "/var/www/cgi">
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    Order allow,deny
    allow from all
</Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log

# Possible values include: debug, info, notice, warn, error, crit,

# alert, emerg.

LogLevel warn

CustomLog ${APACHE_LOG_DIR}/access.log combined

Alias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
    Options Indexes MultiViews FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>

它应该工作，但我有500错误. Apache日志说：

[Fri Sep 19 09:29:04 2014] [error] [client 127.0.0.1] (2)No such file or directory: exec of '/var/www/cgi/env.pl' failed
[Fri Sep 19 09:29:04 2014] [error] [client 127.0.0.1] Premature end of script headers: env.pl

我应该怎么做才能让它工作呢？有没有可能phpmyadmin像这样影响到apache服务器。我做了not use php，除了phpmyadmin的数据库。也许这里是问题所在？
