连接被拒绝 - connect(2) Ruby on Rails 邮件设置

Connection refused - connect(2) Ruby on Rails Mail Setup

提问by Helphin

I have set smtp settings in both config/environments/production.rband development.rbalso i have added the settings in `config/initializers/setup_mail.rb

我已经在两者中设置了 smtp 设置，config/environments/production.rb并且development.rb我还在 `config/initializers/setup_mail.rb 中添加了设置

config.action_mailer.default_url_options = { :host => 'ipaddress' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  :address              => 'smtp.gmail.com',
  :port                 => 587,
  :domain               => 'gmail.com',
  :user_name            => '[email protected]',
  :password             => 'pass',
  :authentication       => :plain,
  :enable_starttls_auto => true,
  :openssl_verify_mode  => 'none'
}

config/initializers/setup_mail.rb

配置/初始化程序/setup_mail.rb

ActionMailer::Base.smtp_settings = { 
  :address              => 'smtp.gmail.com',
  :port                 => 587,
  :domain               => 'gmail.com',
  :user_name            => '[email protected]',
  :password             => 'pass',
  :authentication       => :plain,
  :enable_starttls_auto => true,
  :openssl_verify_mode  => 'none'
} 

ActionMailer::Base.default_url_options[:host] = "ipaddress" 

i am getting the error Connection refused - connect(2)

我收到错误 Connection refused - connect(2)

while i have working in localhost with below configuration I haven't get any error and also mail has been sent.

当我使用以下配置在 localhost 中工作时，我没有收到任何错误，并且邮件也已发送。

config/initializers/setup_mail.rb (localhost)

配置/初始化程序/setup_mail.rb (本地主机)

ActionMailer::Base.smtp_settings = { 
  :address              => 'smtp.gmail.com',
  :port                 => 587,
  :domain               => 'localhost',
  :user_name            => '[email protected]',
  :password             => 'pass',
  :authentication       => 'plain',
  :enable_starttls_auto => true
} 

ActionMailer::Base.default_url_options[:host] = "localhost:3000" 

Errors are show below while running in console,

在控制台中运行时，错误如下所示，

After installing the postfixthe error goes away in console mode and the mails send from console but in graphical mode (in browser) i am getting the error Connection refused - connect(2).

安装后postfix错误在控制台模式下消失，邮件从控制台发送，但在图形模式（在浏览器中）我收到错误Connection refused - connect(2)。

what is wrong,

怎么了，

thanks in advance.

提前致谢。

I see you have tried identical settings on both servers but are having problems only on your production / non-local host environment.

我看到您在两台服务器上尝试了相同的设置，但仅在您的生产/非本地主机环境中遇到问题。

This points to an issue with the network configuration of the environment itself.

这表明环境本身的网络配置存在问题。

In the command line on your same server as your application, try the following command

在与应用程序相同的服务器上的命令行中，尝试以下命令

telnet smtp.gmail.com 587

You should see something like the following

您应该会看到如下所示的内容

telnet smtp.gmail.com 587
Trying 173.194.79.108...
Connected to gmail-smtp-msa.l.google.com.
Escape character is '^]'.
220 mx.google.com ESMTP dd5sm276863pbc.85 - gsmtp

If you do not see this, you will most likely get a connection error. This means your machine does not have access to the gmail server. Likely problems are a) general outbound network connectivity, b) firewalls specifically blocking all outbound connections c) firewalls blocking/allowing connections to particular ports or hosts

如果您没有看到这一点，您很可能会收到连接错误。这意味着您的机器无权访问 gmail 服务器。可能的问题是 a) 一般出站网络连接，b) 防火墙专门阻止所有出站连接 c) 防火墙阻止/允许连接到特定端口或主机

If this does not work, also try the following ports in place of 587

如果这不起作用，请尝试以下端口代替 587

telnet smtp.gmail.com 465
telnet smtp.gmail.com 25

If one of these is more successful, change your mail server settings to use accordingly.

如果其中之一更成功，请相应地更改邮件服务器设置以使用。

Edit: We had quite a bit of trouble using Gmail and then Gmail with our custom domain. One thing that can help is to remove the :domain line from your configuration file, try without it.

编辑：我们在使用 Gmail 和使用自定义域的 Gmail 时遇到了很多麻烦。可以提供帮助的一件事是从配置文件中删除 :domain 行，尝试不使用它。

For reference, here is my Gmail config in prod using our custom domain hosted by Gmail:

作为参考，这是我在 prod 中使用我们由 Gmail 托管的自定义域的 Gmail 配置：

config.action_mailer.default_url_options = { :host => "my.website.com" }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'website.com',
    user_name:            '[email protected]',
    password:             'password',
    authentication:       'plain',
    enable_starttls_auto: true
}

Also, if you do have 2-factor authentication enabled on your Gmail account, you might want to disable it and try this again just to confirm it is not complicating the issue.

此外，如果您在 Gmail 帐户上启用了 2 因素身份验证，您可能需要禁用它并再次尝试以确认它不会使问题复杂化。

You gave the domain as localhost. The domain should be gmail.com. Please change Your config/initializers/setup_mail.rb to

您将域指定为 localhost。域应为 gmail.com。请将您的 config/initializers/setup_mail.rb 更改为

ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'gmail.com', :user_name => '[email protected]', :password => 'pass', :authentication => 'plain', :enable_starttls_auto => true }

ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'gmail.com', :user_name => '[email protected]', :password => 'pass', :authentication => 'plain', :enable_starttls_auto => true }

And in production.rb. You don't need to configure for email address. The following lines are enough.

在 production.rb 中。您不需要配置电子邮件地址。以下几行就足够了。

config.action_mailer.default_url_options = { :host => 'app_url' }
config.action_mailer.delivery_method = :smtp
