我正在尝试使用在Heroku上使用Perloku运行的Mojolicious::Lite应用程序来获得催眠蟾蜍。当hypnotoad进入它的运行循环导致它崩溃时,有些事情不会发生。我想我遗漏了一些简单的东西,但是 Heroku 文档没有帮助,我也无法从中获得好的错误信息。
我从一个非常简单的应用程序开始,所以显示一些环境变量:
#!/usr/bin/env perl
# today
use Mojolicious::Lite;
get '/' => sub {
my $c = shift;
my $content = "Perl: $^X Pid: $$\n\n";
foreach my $key ( keys %ENV ) {
next unless $key =~ /Mojo|toad/i;
$content .= "$key $ENV{$key}\n";
}
$c->stash( content => $content );
$c->render('index');
};
app->start;
__DATA__
@@ index.html.ep
% layout 'default';
% title 'Welcome';
<p>Welcome to the Mojolicious real-time web framework!</p>

<%= $content %>
</pre>
@@ layouts/default.html.ep
<!DOCTYPE html>
<html>
<head><title><%= title %></title></head>
<body><%= content %></body>
</html>
当我在本地运行它时,我没有问题。我从环境变量中看到我的程序是在 hypnotoad 下运行的:
Welcome to the Mojolicious real-time web framework!
Perl: /Users/brian/Dropbox/bin/perls/perl5.20.0 Pid: 40006
HYPNOTOAD_PID 39981
MOJO_HELP
HYPNOTOAD_TEST
HYPNOTOAD_EXE /Users/brian/bin/perls/hypnotoad5.20.0
MOJO_REUSE 0.0.0.0:8080:6
HYPNOTOAD_REV 3
HYPNOTOAD_APP /Users/brian/Desktop/toady.d/toady
MOJO_MODE production
MOJO_HOME
HYPNOTOAD_STOP
HYPNOTOAD_FOREGROUND
现在,我使用Mojolicious::Command::deploy::heroku 部署它:
% toady deploy heroku --create
这是在https://frozen-brushlands-4002.herokuapp.com上运行的,使用默认的 Perloku 文件:
#!/bin/sh
./toady daemon --listen http://*:$PORT --mode production
尽管我看过一些参考资料说这就是我应该得到的,但这并不是运行催眠蟾蜍。该应用程序有效,但:
Welcome to the Mojolicious real-time web framework!
Perl: /app/vendor/perl/bin/perl Pid: 3
MOJO_REUSE 0.0.0.0:12270:4
MOJO_HOME
MOJO_HELP
MOJO_MODE production
MOJO_EXE ./toady
我想我可以更改 Perloku 文件来启动 hypnotoad:
#!/bin/sh
/app/vendor/perl/bin/perl /app/vendor/perl-deps/bin/hypnotoad toady
hypnotoad 启动并几乎立即关闭,没有其他日志消息:
% heroku logs --app ...
2015-01-04T09:23:36.516864+00:00 heroku[web.1]: Starting process with command `./Perloku`
2015-01-04T09:23:38.321628+00:00 heroku[web.1]: State changed from starting to crashed
我可以更改调用以使用-t
来测试应用程序以查看是否:
#!/bin/sh
/app/vendor/perl/bin/perl /app/vendor/perl-deps/bin/hypnotoad -t toady
那行得通,我得到“一切看起来都很好!” 消息,所以 hypnotoad 正在运行:
2015-01-04T09:36:36.955680+00:00 heroku[web.1]: Starting process with command `./Perloku`
2015-01-04T09:36:38.340717+00:00 app[web.1]: Everything looks good!
2015-01-04T09:36:39.085887+00:00 heroku[web.1]: State changed from starting to crashed
我打开了 Mojo 调试日志记录,但除了我自己的语句之外,我没有看到其他输出。
#!/usr/bin/env perl
use Mojolicious::Lite;
$|++;
my $log = app->log;
$log->level( 'debug' );
$log->debug( "INC: @INC" );
get '/' => sub {
...;
};
$log->debug( "Right before start" );
my $app = app->start;
$log->debug( "Right after start" );
$app; # must return application object
我尝试了其他事情,例如让它加载一个我知道不存在的模块,并且我在日志中得到预期的“找不到”错误。
从 heroku ( heroku run bash
) 中的 shell 运行没有启发性。的输出与mojo version
我的本地机器上的相同:
$ perl vendor/perl-deps/bin/mojo version
CORE
Perl (v5.16.2, linux)
Mojolicious (5.71, Tiger Face)
OPTIONAL
EV 4.0+ (n/a)
IO::Socket::Socks 0.64+ (n/a)
IO::Socket::SSL 1.84+ (n/a)
Net::DNS::Native 0.15+ (n/a)
You might want to update your Mojolicious to 5.72.
我认为我缺少一些非常简单的东西,但与此同时,这些都不是为了便于调试而设计的。
奥列格离得更近了一点,但仍然存在问题。我之前尝试过前台选项并遇到同样的问题,但没有提及。
如果我在前台启动 hypnotoad,它会尝试绑定到一个地址。它无法绑定到端口 80(或 443)并崩溃,它可以监听 127.0.0.1: 几乎,但看起来它无法完全监听:
