ウエブカメラ通話アプリケーションPeerJSとそのPeerServerのインストールと設定と自動起動を記載しました。

■PeerServerダウンロード
# cd /opt
# git clone https://github.com/peers/peerjs-server.git

■PeerServerの依存ライブラリインストール
# cd peerjs-server

# npm install
npmはnode.jsのpackage管理ツール

■PeerJSダウンロード

$ cd /opt
$ git clone https://github.com/peers/peerjs.git

videochatのデモをnginxの下に配置
$ cd /var/www/html/xxxx
$ mkdir peerjs
$ cp /opt/peerjs/examples/videochat/* /var/www/html/xxxx/peerjs

$ cp /opt/peerjs/dist/peer.js　 /var/www/html/xxxx/peerjs
以下のdiffのようにindex.htmlを修正

$ vi　peerjs/index.html
# diff index.html /opt/peerjs/examples/videochat/index.html

< var peer = new Peer({host:’192.xxx.xxx.xxx’, port:9000, key: ‘peerjs’, debug: 3}); — > var peer = new Peer({ key: ‘lwjd5qra8257b9′, debug: 3});
PeerServer起動

PeerServerの自動起動設定
$ vi /etc/init/peerjs.conf
description “PeerJS Server”
author “co-meeting Inc.”

# Saves log to /var/log/upstart/peerjs.log
console log

# Starts only after drives are mounted.
start on started mountall

stop on shutdown

# Automatically Respawn. But fail permanently if it respawns 10 times in 5 seconds:
respawn
respawn limit 10 5

script
node /opt/peerjs-server/bin/peerjs -p 8124 -k peerjs
end script
起動コマンドオプションの-k peerjsはクライアントのnew Peer({host:’’, port:8124, key: ‘peerjs’, debug: 3})のkeyと一致

80番と8124番ポート解放
