mojoliciousのデプロイ
会社でmojoliciousを使って開発したサービスがあるのですが、
リリースが近づいてきたのでデプロイをどうするか決めることに。
perlのWAF使ったデプロイをしたことがないので
どの方法がいいか決めかねている。
そのためいろいろ試してみて問題なさそうなのを採用。
デプロイ参考
MojoのCookBookを参考にしてみる*1
http://github.com/kraih/mojo/blob/master/lib/Mojolicious/Guides/Cookbook.pod
ただし、nginxとfast-cgiは除外。
nginxは使ったことない。fcgiは設定うまく行かなかった
サーバは貧弱
なのでなるだけリソースを使わない方法がいいかも*2
調査方法
apachebenchで負荷かけてその様子をみる。
本当はvmstatとかsarとか見るべきかもしれないが、
今回はtopだけでなんとなく眺めるだけにする。
意味ないかもしれないけど、topはスナップショットを張り付けてみる
サーバ環境(vmware server)
| os | CentOS 5.3 64bit |
| メモリ | 1G |
| CPUコア | 2 |
| perl | 5.12.1 |
| apache | 2.2.15 |
| mojolicious | 0.999926 |
テストアプリ
mojolicious generate app Demo2
で生成したアプリで「/」にアクセス。
テスト１：mojoのdaemon
コマンド
