ステージング環境に直接入ってコマンド打っても起動せぇへん
bundle exec unicorn -c /var/www/hogehoge/current/config/unicorn/stage.rb -E deployment -D
停止はできるっぽい
kill -QUIT `cat /var/www/hogehoge/current/tmp/pids/unicorn.pid`
入らんでも外からできるんちゃう？exitしてから
bundle exec cap stage unicorn:start
でけた、停止は
bundle exec cap stage unicorn:stop
sidekiqの場合はこれでおk
bundle exec cap stage sidekiq:start
標準だけだと足り無いのでカスタム用メトリックスを作成

エラー解消方法 公開鍵をssh-addする
ssh-add -l The agent has no identities. ssh-add ~/.ssh/id_rsa Identity added: /Users/hoge/.ssh/id_rsa (/Users/hoge/.ssh/id_rsa) ssh-add -l 2048 23i4u2oi:5c:21:da:23423498:be:00:58:629387:cd:12:18:18:7c:14 /Users/hoge/.ssh/id_rsa (RSA) #永続的にaddする方法 ssh-add -K ~/.ssh/id_git_rsa
sidekiqでのエラーハンドリング config/initializers/sidekiq.rb
Sidekiq.configure_server do |config|
config.redis = { url: 'redis://127.0.0.1:3333' }
end
config.redisの下に以下を追加
config.error_handlers << Proc.new { |ex, ctx_hash| ExceptionNotifier.notify_exception(ex) }
viewでそれぞれ書くのがめんどくさかったんでmodelに定義 human_hoge
['hoge', 'hoge2', 'hoge3'].each do |method|
define_method "human_#{method}" do
I18n.t("activerecord.attributes.applicant.#{method.pluralize}").fetch(send(method).to_sym)
end
end
クラスメソッドバージョン
['hoge', 'hoge2', 'hoge3'].each do |method|
define_singleton_method "collection_#{method}" do
send(method.pluralize).map{|k,v| [I18n.t("activerecord.attributes.applicant.#{method.pluralize}.#{k}"),k]}.to_h
end
end
公開鍵作成
cd ~/.ssh/ ssh-keygen -t rsa
クリップボードにコピー
pbcopy < ~/.ssh/id_rsa.pub
github側で登録 https://github.com/settings/ssh
app/.git/configを書き換え
[remote "origin"] url = git@github.com:hoge/hoge.git
毎回パスワード聞かれないように
ssh-add ~/.ssh/id_rsa
