AWS OpsWorks - 无法使用AWS OpsWorks部署我的应用程序，尤其是无法成功迁移

标签： amazon-web-services aws-opsworks

遵循此文档（http://railsconf2015-aws.s3-website-us-east-1.amazonaws.com/），我正在尝试使用AWS OpsWorks部署我的rails应用程序。但是，我没有做到，特别是当我试图迁移它时。

这是错误日志。

它似乎成功进行了“捆绑安装”。

使用ssh，我去了/ srv / www / sample_app / releases / 20150726082129并输入了

rake db:migrate

然后出现错误句子。

Could not find i18n-0.7.0 in any of the sources
Run `bundle install` to install missing gems.

接下来，按照这个错误句子，我输入了

sudo bundle install

然后它说

Your bundle is complete!
Gems in the groups test and development were not installed.
It was installed into /home/deploy/.bundler/sample_app

然而，宝石似乎是空的。如果我输入

gem list

我找不到Gemfile中指定的gems 

bigdecimal (1.2.6)
bundler (1.5.3)
io-console (0.4.3)
json (1.8.1)
kgio (2.9.3)
minitest (5.4.3)
power_assert (0.2.2)
psych (2.0.8)
rack (1.6.4)
raindrops (0.15.0)
rake (10.4.2)
rdoc (4.2.0)
test-unit (3.0.8)
unicorn (4.7.0)

我认为这些是解决我的问题的提示。

对不起，我不太擅长英语，所以如果你不明白我想要你帮忙的话，请告诉我一点未知的事。

Opworks is a pain to debug via their logs. here are some tips to debug.

You cannot do it in the normal ec2-user account you may be using to ssh. Do this command to be the deploy user ... 

sudo su - deploy

which will then allow you to go to your app at the current location ...

cd /srv/www/sample_app/current

you will now also be able to see logs, run rake, and such. In particular, now you can run your failed command ...

if [ -f Gemfile ]; then echo 'OpsWorks: Gemfile found - running migration with bundle exec' && /usr/local/bin/bundle exec /usr/local/bin/rake db:migrate; else echo 'OpsWorks: no Gemfile - running plain migrations' && /usr/local/bin/rake db:migrate; fi

One place to look is in the shared area configuration, logs, i.e. ...

/srv/www/sample_app/shared/config/unicorn.conf

答案 1 :(得分：0)

我已经使用OpsWorks来大量部署rails应用程序，这种部署错误很常见。

如果您在OpsWorks中部署Ruby on Rails应用程序时遇到迁移错误，只需 SSH 到服务器并转到最后部署文件夹（例如，对于您的情况） ：/ srv / www / sample_app / releases / 20150726082129）。

请注意“/ srv / www / {your app name} / current”只会指向您上次从OpsWorks成功部署，如果部署失败，最好直接访问“/ srv”下的最新部署文件夹/ www / {your app name} / releases / {deployment time}“

而不是

rake db:migrate

您应该运行 

sudo bundle exec rake db:migrate

然后，您将看到更有意义的迁移错误，然后您应该知道该怎么做。

答案 2 :(得分：0)

我发现了问题，至少它对我有用。

迁移失败的原因可能有很多原因，OpsWorks日志无法帮助我们。 正如你们许多人建议的那样，要确切了解发生了什么，我们必须通过SSH登录我们的某个实例并尝试运行导致失败的命令。

通过ssh登录然后： su - deploy $ cd /srv/www/mynextapp/releases/20150401052640 $ /usr/local/bin/bundle exec /usr/local/bin/rake db:migrate

现在这个命令应该失败，告诉我们原因。

@ n1t1nv3rma收到此错误：

ExecJS::RuntimeUnavailable: Could not find a JavaScript runtime

他修好了in this way.

对我来说错误是： /usr/lib/postgresql/9.5/bin/pg_dump: invalid option -- 'i' Try "pg_dump --help" for more information. rake aborted! Error dumping database

我修复了它只是更新到Rails 4.2.6 （之前是4.2.3 - 有一个删除-i选项的提交）。

希望它有所帮助。
