AWS OpsWorks-無法使用AWS OpsWorks部署我的應用程序，尤其是無法成功遷移

Question

遵循此文檔（ http://railsconf2015-aws.s3-website-us-east-1.amazonaws.com/ ），我正在嘗試使用AWS OpsWorks部署rails應用程序。 但是，我做不到，尤其是當我嘗試遷移它時。

這是錯誤日志。

好像成功了“捆綁安裝”。

使用ssh，我轉到/ srv / www / sample_app / releases / 20150726082129並輸入

rake db:migrate

然后出現這樣的錯誤句子。

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

接下來，按照此錯誤語句，我輸入

sudo bundle install

然后它說

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

但是，看來寶石是空的。 如果我輸入

gem list

我找不到Gemfile中指定的寶石

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)

我認為這些是解決我的問題的提示。

對不起，我的英語水平太差了，所以，如果您聽不懂我想給您的幫助，請告訴我一個未知數。

Answer 1

Opworks很難通過其日志進行調試。 這里有一些調試技巧。

您無法使用可能用於ssh的普通ec2用戶帳戶來執行此操作。 做這個命令成為部署用戶...

sudo su - deploy

然后，您可以在當前位置轉到您的應用...

cd /srv/www/sample_app/current

您現在還可以查看日志，運行rake等。 特別是，現在您可以運行失敗的命令...

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

一個值得一看的地方是共享區域配置，日志，即...

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

Answer 2

我已經使用OpsWorks大量部署了Rails應用程序，這種部署錯誤很常見。

如果您因在OpsWorks中部署Ruby on Rails應用程序而遇到某種遷移錯誤，則只需SSH到服務器，然后轉到最后一個部署文件夾 （例如：/ srv / www / sample_app / releases / 20150726082129）。

請注意，“ / srv / www / {您的應用程序名稱} /當前”將僅指向您從OpsWorks成功完成的部署，如果部署失敗，則最好直接訪問“ / srv / www /”下的最新部署文件夾{您的應用名稱} /版本/ {部署時間}”

代替

rake db:migrate

你應該跑

sudo bundle exec rake db:migrate

然后，您將看到更多有意義的遷移錯誤，並且您應該知道該怎么做。

Answer 3

我發現了問題，至少對我有用。

遷移失敗的原因可能取決於很多原因，而OpsWorks日志也無濟於事。 因此，正如許多人建議的那樣， 要確切了解發生了什么，我們必須通過SSH登錄到我們的實例之一，然后嘗試運行導致失敗的命令。

通過ssh登錄，然后： su - deploy $ cd /srv/www/mynextapp/releases/20150401052640 $ /usr/local/bin/bundle exec /usr/local/bin/rake db:migrate

現在此命令應該失敗，向我們顯示原因。

@ n1t1nv3rma出現此錯誤：

ExecJS::RuntimeUnavailable: Could not find a JavaScript runtime

然后他以這種方式修復了它。

對我來說，錯誤是： /usr/lib/postgresql/9.5/bin/pg_dump: invalid option -- 'i' Try "pg_dump --help" for more information. rake aborted! Error dumping database /usr/lib/postgresql/9.5/bin/pg_dump: invalid option -- 'i' Try "pg_dump --help" for more information. rake aborted! Error dumping database

我固定了它，只是更新到Rails 4.2.6 （在4.2.3之前-有一個刪除--i選項的提交）。

希望能幫助到你。
