rvm環境のthinサーバをdaemontoolsで動かすためのrunスクリプト。thin startの行を変更すればthinに限らないです。softlimitは必要であれば。
#!/bin/sh
exec 2>&1
exec \
sh -c '

export LANG=ja_JP.utf8

ApacheとOpenSSLをコンパイルする。 都合DSOは使わないことにした。 mod_sslはhttpd実行時にlibssl.soを呼ぶが、LIB_LIBRARY_PATHを設定せずhttpdを起動するとシステムワイドな/usr/lib64/libssl.soが呼ばれて意図しないOpenSSLバージョンで起動してしまう問題に悩まされたときのメモ。

# sharedオプションでlibssl.soを作る
./Configure shared --prefix=/usr/local/openssl-x.x.x

Rails 4系をgemでインストール
gemは3系バージョンなのでバージョンを指定する。
$ gem gemset create test
$ gem gemset use test
$ gem install rails --version 4.0.0.rc1 --no-ri --no-rdoc

rbenv環境でcrontabでスクリプトを実行。いろいろ微妙な気がしている。
