[求助]linux下apache运行perl出错
apache的配置是：
1、DocumentRoot "/var/www/html"
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory "/var/www/html">
Options FollowSymLinks [color=red]ExecCGI[/color]
AllowOverride None
Order allow,deny
Allow from all
</Directory>
2、DirectoryIndex index.html index.html.var[color=red] index.pl [/color] index.htm index.cgi
3、[color=red]AddHandler cgi-script .pl[/color]
注：红色的为配置部分

源文件在：/var/www/html/index/index.pl

元程序为：
#!/usr/bin/perl
use CGI;
use DBI;
my $cgi=new CGI;
print $cgi->header();
print "记录条数是：";
my $dbh=DBI->connect('dbi:mysql:mysql','root',,);
my $sth=$dbh->prepare("select count(*) from user");
$sth->execute;
my $row=$sth->fetchrow_array;
print "$row\n";
其中：CGI DBI模块都已经安装了

IE页面显示：
