ec2onrails本編

5. Copy your public key from the server to keep Capistrano happy
config/deploy.rb、config/s3.ymlの中身をきちんと書く時が来たようだ。
s3.ymlとdeploy.rbをだいたい書いた。(access key とかec2のホスト名だとか、すごくわかりやすい箇所。ってそれを書いておかないと後でたぶん困る。)
deploy.rb------
ssh_options[:keys] = ["#{ENV['HOME']}/.ssh/id_rsa-gsg-keypair"]
と書いて
$ cap ec2onrails:get_public_key_from_server
* executing `ec2onrails:get_public_key_from_server'
Your first key in ssh_options[:keys] is /Users/code/.ssh/id_rsa-gsg-keypair, presumably that's
your EC2 private key. The public key will be copied from the server
named 'ec2-11-111-11-111.compute-1.amazonaws.com' and saved locally as /Users/code/.ssh/id_rsa-gsg-keypair.pub. Continue? [y/n]

6. Deploy the app with Capistrano
$ cap ec2onrails:setup
ubuntu関係の諸々がec2マシンへインストールされていく。
しばしログが流れる。
rmagick関連でエラーが出た。

RMagick 2.5.2 のインストールに失敗したよ。
というのもMagick-config が /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/binのどこにも見当たらないから。

rmagickはすぐには使わないから後でインストールすることにしよう。

config/database.yml
SQLite version 3.x
# gem install ec2-11-111-11-1.compute-1.amazonaws.com (not necessary on OS X Leopard)
（略）
production:
adapter: sqlite3
database: db/production.sqlite3
timeout: 5000
いつもmysqlなのでsqlite3の場合の書き方がわからん。
ひとまずsqlite3-rubyを入れるか、と思ったけど、ここで小休憩。。。
database.ymlをmysql用の書き方にして、
DBのパスワードはこちらの値を一緒にして
（DBのusernameはrootのまま）
config/deploy.rb
:mysql_root_password => "xxxxxxx",
再度実行したら
$ cap ec2onrails:setup
無事完了した。
残課題：imagemagick、rmagickをまだinstallしていないこと。

さらに前に進みます。

そう、config/deploy.rbでのscmの設定をしていない。
ソースリポジトリが必須ということか。そりゃそうなんだけど。
どこに用意するか。。。。
