unicorn.logをlogrotate.dでローテするメモ
基本的にはUSR1シグナルを送れば良い
sample
/var/log/foo/bar/unicorn.log {
daily #毎日
missingok # ログファイルがなくても処理をつづける
rotate 7 #世代
dateext #ファイルを日付形式に
compress #圧縮する
delaycompress #圧縮は次のローテまで遅らせる
lastaction
pid=/foo/bar/unicorn.pid
test -s $pid && kill -USR1 "$(cat $pid)"
endscript
}
豆
- logrotate.dのファイルのパーミッションは煩い。0644
参考
Jenkins2.xで、jobの実行ユーザを取得するgroovyスニペット
println currentBuild.getRawBuild().getCause(hudson.model.Cause$UserIdCause).getUserName()
めんどいのぅ
やりたいことはこっちでもできた（すこし短くなった）
currentBuild.build().getCause(Cause.UserIdCause.class).getUserName()
更に、.classも省略できる
currentBuild.build().getCause(Cause.UserIdCause).getUserName()
複数サーバの設定をserverspecに食わせて実行するサンプル

"host2":
:roles:
