시작하면 8888에 웹서버도 띄워진다
http://localhost:8888/

자. 그럼 REST 방식으로 데이터베이스를 만들어보자.
~ $ telnet localhost 8888

잘 되는군하.
이제 문서를 만들어 봐야하는데 일단 간단히 php를 이용해보자
서브버전으로 받은 소스에 관련 라이브러리가 포함되어 있는데 압축이 되어 있으므로 일단 푼다
~ $ cd ~/build/couchdb/CouchProjects/Libraries
~/build/couchdb/CouchProjects/Libraries $ ls
CouchDb-C-Library.tar.gz c sample.php
CouchDb-PHP-Library.tar.gz php
~/build/couchdb/CouchProjects/Libraries $ tar xvzf CouchDb-PHP-
Library.tar.gz
~/build/couchdb/CouchProjects/Libraries $ cd CouchDb-PHP-Library
~/build/couchdb/CouchProjects/Libraries/CouchDb-PHP-Library $ ls
CouchDb Library Net_URL Tests
HTTP_Request Net_Socket PEAR

여기에 다음과 같은 내용의 sample.php 파일을 만들어 보자
<?php
include "CouchDb/Couch.php";
$server = "localhost";
$database = "test";
$couch = new Couch($server, $database);

$doc = new CouchDocument;
$doc->set("title", "hola");
$docId = $couch->save($doc);

echo $docId;
?>

실행하면
~/build/couchdb/CouchProjects/Libraries/CouchDb-PHP-Library $ php
sample.php
D5C07F53F013D5CB35A465C899F4FB79

브라우저에서 확인해보자
