新しい環境からHerokuの既存アプリを更新

普段はあまり更新しないTwitter botがあるのだけど、久々に更新しようとしたところ今メインで使っているMBAから更新したことがないので環境構築からスタートする。 Herokuでcronがセットしてあるbotなので、Heroku環境構築。

まず、gitをインストール

$ brew install git
以下省略

いろいろ調べると、rvmを使うとrubyのバージョンが管理できて便利とのことなのでインストールする。

$ bash -s stable < <(curl -s 
https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

.bash_profileにパスを通す。

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

これでrvmが使える。インストールしてみよう。

$ rvm install 1.9.3-p125

どれどれバージョンチェック。

$ ruby -v

便利だ！
それではherokuを入れてみよう。

$ gem install heroku

入ったかな。heroku listコマンドでアプリケーションを確認する。

$ heroku list
Enter your Heroku credentials.
Email: ****@***.**.**
Password (typing will be hidden): 
=== My Apps
*****
*****
*****

よしよし、問題なさそう。
herokuからアプリをcloneする場合のコマンドは以下とのことなのでやってみる。

$ git clone git@heroku.com:アプリ名.git
Cloning into 'アプリ名'...
Warning: Permanently added the RSA host key for IP address '***.***.***.***' to the list of known hosts.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

お、失敗した。
どうやらcloneする場合はRSAキーをHerokuに登録しなければならないようだ。

$ heroku keys:add
Could not find an existing public key.
Would you like to generate one? [Yn] Y
Generating new SSH public key.
Uploading SSH public key /Users/***/.ssh/***.pub... done

$ git clone git@heroku.com:アプリ名.git
Cloning into 'アプリ名'...
remote: Counting objects: 95, done.
remote: Compressing objects: 100% (79/79), done.

Receiving objects: 100% (95/95), 94.58 KiB | 80 KiB/s, done.
Resolving deltas: 100% (20/20), done.

成功。 /home/ユーザー名/ 配下にアプリ名のフォルダができた！
でもこのまま git push heroku master すると失敗するらしくremote addしておく必要があるとのことで以下を入力。

$ git remote add heroku git@heroku.com:アプリ名.git

ここまできたらもうあとはいつものHerokuですね。

$ git add .
$ git commit -m 'a'
$ git push heroku master

以上、新しいMac環境からのHeroku更新が無事にうまくいきました。いやー、Heroku便利ですねー。

LionにHomebrew入れてec2-api-toolsを動かす

本業が営業なので最新技術は追いつつもあまりコマンドラインは触らない（好きだけど）のでMacにはPortsが入っていたが、同僚から「今時はHomebrew、Portsはありえない」ような話を聞いて、んじゃ入れなおしてみるかと。

$ /usr/bin/ruby -e "$(/usr/bin/curl -fsSL https://raw.github.com/mxcl/homebrew
/master/Library/Contributions/install_homebrew.rb)"
==> This script will install:
/usr/local/bin/brew
/usr/local/Library/Formula/...
/usr/local/Library/Homebrew/...

Press enter to continue
==> /usr/bin/sudo /bin/mkdir /usr/local
Password:
==> /usr/bin/sudo /bin/chmod g+rwx /usr/local
==> /usr/bin/sudo /usr/bin/chgrp admin /usr/local
==> Downloading and Installing Homebrew...
==> Installation successful!
You should run `brew doctor' *before* you install anything.
Now type: brew help

む、brew doctor とな。

$ brew doctor
Error: You have no /usr/bin/cc.
This means you probably can't build *anything*. You need to install the Command
Line Tools for Xcode. You can either download this from http://connect.apple.com
or install them from inside Xcode's Download preferences. Homebrew does not
require all of Xcode! You only need the Command Line Tools package!
Error: Git could not be found in your PATH.
Homebrew uses Git for several internal functions, and some formulae use Git
checkouts instead of stable tarballs. You may want to install Git:
  brew install git
Error: Your Xcode is configured with an invalid path.
You should change it to the correct path. Please note that there is no correct
path at this time if you have *only* installed the Command Line Tools for Xcode.
If your Xcode is pre-4.3 or you installed the whole of Xcode 4.3 then one of
these is (probably) what you want:

    sudo xcode-select -switch /Developer
    sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

DO NOT SET / OR EVERYTHING BREAKS!

どうやらいろいろ足らないようだ。 Xcode の Command Line Tools をAppleのサイトからインストール。んでgitをinstall。

エラーがでてるけど、まぁいいや、あとでみるか。
ではec2-api-toolsを入れてみよう。

$ brew install ec2-api-tools
==> Downloading http://ec2-downloads.s3.amazonaws.com/ec2-api-tools-1.5.2.5.zip
######################################################################## 100.0%
==> Caveats
Before you can use these tools you must export some variables to your $SHELL
and download your X.509 certificate and private key from Amazon Web Services.

Your certificate and private key are available at:
http://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key

Download two ".pem" files, one starting with `pk-`, and one starting with `cert-`.
You need to put both into a folder in your home directory, `~/.ec2`.

To export the needed variables, add them to your dotfiles.
 * On Bash, add them to `~/.bash_profile`.
 * On Zsh, add them to `~/.zprofile` instead.

export JAVA_HOME="$(/usr/libexec/java_home)"
export EC2_PRIVATE_KEY="$(/bin/ls "$HOME"/.ec2/pk-*.pem | /usr/bin/head -1)"
export EC2_CERT="$(/bin/ls "$HOME"/.ec2/cert-*.pem | /usr/bin/head -1)"
export EC2_HOME="/usr/local/Library/LinkedKegs/ec2-api-tools/jars"
==> Summary
/usr/local/Cellar/ec2-api-tools/1.5.2.5: 322 files, 15M, built in 41 seconds

うん、入ったな、どれどれ。

$ ec2ver
-bash: ec2ver: command not found

パスが通ってない、そりゃそうだ。ec2-api-toolsインストール時に表示されていた内容どおりに設定。具体的には pk-***.pem と cert-***.pem を ~/.ec2 に配置して、/.bash_profileにバスを通す。

$ ec2ver
1.5.2.5 2012-03-01

動いた。これで rds-command-line-tools とか elb-tools も簡単に入るみたいなので便利な気がする。よしよし。
