nginxとjettyの連携
jettyはpure javaのWebサーバ、サーブレット。spdyやwebsocketも対応。nginxからtomcatという連携もあるが、ならapache使えよと思わなくもないのでjettyにしてみた。
jetty
http://download.eclipse.org/jetty/ からリリース版をダウンロードしてインストール。

とエラーがでる。javaのバージョンがまずい。

なのでyumでアップデートしてみた。

再度、起動してみる。
# java -jar ../start.jar 2015-03-27 08:59:05.829:INFO::main: Logging initialized @862ms 2015-03-27 08:59:06.248:WARN::main: demo test-realm is deployed.

http://localhost:8080 で接続できた。
なお、jettyを起動時に動作させるには、dist/bin/jetty.sh を /etc/init.d 配下にコピーする。このスクリプトには必要な環境変数設定(JETTY_HOME)などの説明が書いてあるのでそれを参考に設定する。
nginxをつかってリダイレクト
80から8080にリダイレクトさせる設定を行う。
# cd /etc/nginx/conf.d # cat jetty.conf # # Redirecting to jetty servlect # server { listen 80; server_name _; access_log /var/log/nginx/jetty.access.log main; location /jetty/ { proxy_http_version 1.1; proxy_pass http://localhost:8080/; proxy_redirect http://localhost:8080/ /; proxy_cookie_path /jetty /; } } # /etc/init.d/nginx start
http://localhost/jetty/ これで接続可能。
