我试图用0700应用程序在
Heroku和
Perloku上运行催眠器.当
hypnotoad进入其运行循环导致它崩溃时,会发生一些事情.我想我错过了一些简单的东西,但Heroku文档没有帮助,我无法从中哄骗好的错误信息.
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>
<pre>
<%= $content %>
</pre>
@@ layouts/default.html.ep
<!DOCTYPE html>
<html>
<head><title><%= title %></title></head>
<body><%= content %></body>
</html>
当我在本地运行时,我没有问题.我从环境变量中看到我的程序是在hypnotoad下运行的：
Welcome to the MojolicIoUs real-time web framework! Perl: /Users/brian/DropBox/bin/perls/perl5.20.0 Pid: 40006 HYPNOTOAD_PID 39981 MOJO_HELP HYPNOTOAD_TEST HYPNOTOAD_EXE /Users/brian/bin/perls/hypnotoad5.20.0 MOJO_REUSE 0.0.0.0:8080:6 HYPNOTOAD_REV 3 HYPNOTOAD_APP /Users/brian/Desktop/toady.d/toady MOJO_MODE production MOJO_HOME HYPNOTOAD_STOP HYPNOTOAD_FOREGROUND
现在,我用Mojolicious::Command::deploy::heroku部署它：
% toady deploy heroku --create
这是在https://frozen-brushlands-4002.herokuapp.com运行,使用默认的Perloku文件：
#!/bin/sh ./toady daemon --listen http://*:$PORT --mode production
尽管有一些参考文献我已经看到过这就是我应该得到的东西,但这并没有运行催眠术.该应用程序可行：
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文件以启动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
这有效,我得到“一切看起来都很棒！”消息,所以催眠运行正在运行：
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
我尝试了其他的东西,比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了预期的“找不到”错误.
从heroku(heroku run bash)中的shell运行并不是很有启发性. mojo版本的输出与我本地机器上的输出相同：
$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.
我认为有一些非常简单的东西我不知道,但与此同时,这些都不是为了便于调试而构建的.
Oleg离得更近了,但仍有问题.我之前尝试过前台选项并遇到同样的问题,但没有提到它.
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,并且它可以监听127.0.0.1：几乎,但看起来它无法完全侦听：

解决方法
这真是一个疯狂的猜测,但也许heroku基础设施不期望跑步者终止？如果是这样,您可以尝试使用–foreground或-f启动hypnotoad.
此外,您可以尝试从应用程序内部进行一些日志记录,以查看它是否曾经运行过它.
