简介:我们公司使用通过 mod_perl 动态生成的虚拟主机从我们的数据库中生成虚拟主机。我们基本上有一个表“域”,它为我们的数百个客户和合作伙伴动态修改。
我们有几种具有不同别名、包含和规则的模板。所以我们基本上使用下面的 Perl 脚本来生成不同的模板:
<Perl>
#!perl
use DBI;
use Time::HiRes qw(time);
use Apache2::ServerUtil ();
my $s = Apache2::ServerUtil->server;
$Apache2::PerlSections::Save = 1;
my $dsn = "dbi:mysql:...:...";
my $user = "...";
my $pw = "...";
my $db = DBI->connect($dsn, $user, $pw) or die $DBI::errstr;
my $select = qq/SELECT * FROM domains ORDER BY ID/;
my $sth_select = $db->prepare($select);
$sth_select->execute() or die $DBI::errstr;
my @row;
while( @row = $sth_select->fetchrow_array ) {
$My::domain = @row[1];
$My::dir = @row[3];
$My::template = @row[4];
$s->add_config(["Include /srv/www/vhosts/templates/".$My::template]);
}
</Perl>
在模板中,我们通过 perl 循环中使用的变量来定义主机名。
出于预览目的,我们希望使用数据库控制的登录来保护一些项目/域。这就是 mod_atuhn_dbd 进入游戏的地方。
这是我们为不同项目和实际问题开始的数据库登录的最终解决方案:
<VirtualHost *:80>
DBDriver mysql
DBDParams "host=... dbname=... port=3306 user=... pass=..."
DBDMin 1
DBDKeep 2
DBDMax 10
DBDExptime 60
<Perl>
use File::Copy;
$ServerName = $My::domain;
$DocumentRoot = "/srv/www/".$My::dir;
$Directory {"/srv/www/".$My::dir} = {
AllowOverride => "All",
Order => "allow,deny",
deny => "from all",
Satisfy => "Any",
Require => "valid-user",
AuthType => "Basic",
AuthName => "Achtung",
AuthBasicProvider => "socache dbd",
AuthnCacheProvideFor => "dbd",
AuthnCacheContext => "Test",
AuthnCacheTimeout => "60",
AuthDBDUserPWQuery => "SELECT `user_passwd` FROM prev_user` WHERE `host_name` = '".$My::dir"' AND `user_name` = %s"
};
</Perl>
</VirtualHost>
问题是 - Apache 说:
apache2[10988]: $parms->add_config() has failed:
AuthDBDUserPWQuery takes one argument, Query used to fetch password for user at /usr/lib/x86_64-linux-gnu/perl5/5.20/Apache2/PerlSections.pm line 216.\n
如果我从 perl 部分中删除指令并将其直接放入虚拟主机中,它会按预期工作,用户将收到提示并且必须通过数据库参数登录。太糟糕了,没有选项可以在查询中使用动态主机,所以这不会真正起作用。
<VirtualHost *:80>
<Perl>
[...]
$Directory {"/srv/www/".$My::dir} = {
AllowOverride => "All",
Order => "allow,deny",
deny => "from all",
Satisfy => "Any",
Require => "valid-user",
AuthType => "Basic",
AuthName => "Achtung",
AuthBasicProvider => "socache dbd",
AuthnCacheProvideFor => "dbd",
AuthnCacheContext => "Test",
AuthnCacheTimeout => "60"
};
</Perl>
<Directory /srv/www/websites/admin>
AuthDBDUserPWQuery "SELECT `user_passwd` FROM prev_user` WHERE `host_name` = '[NEED DYNAMIC HOST HERE]' AND `user_name` = %s"
</Directory>
</VirtualHost>
以下部分似乎存在一些奇怪的问题:
$Directory {"/srv/www/".$My::dir} = {
[...]
AuthDBDUserPWQuery => "SELECT `user_passwd` FROM prev_user` WHERE `host_name` = '".$My::dir"' AND `user_name` = %s"
};
有什么建议么?
