使用php访问zookeeper服务

下载zookeeper依赖库：
http://apache.fayea.com/zookeeper/zookeeper-3.4.6/
解压
tar -zxf zookeeper-3.4.6.tar.gz
cd zookeeper-3.4.6/src/c
安装
./configure --prefix=/usr/local/zookeeper/zookeeper-3.4.6/
make & make install

下载PHPzookeeper扩展库：
http://pecl.php.net/package/zookeeper

解压
tar -zxvf zookeeper-3.4.6.tar.gz
安装
/usr/local/php5.4/bin/phpize
./configure --with-php-config=/usr/local/php5.4/bin/php-config --with-libzookeeper-dir=/usr/local/zookeeper/zookeeper-3.4.6/
make & make install

编辑配置php
vim /usr/local/conf/php5.4/php.ini
/usr/local/php5.4/bin/php -m

l /usr/local/php5.4/lib/php/extensions/no-debug-non-zts-20100525
重启fpm
kill -USR2 `cat /usr/local/php5.4/var/run/php-fpm.pid`

测试访问zookeeper服务状态：
vim test_zookeeper.php

<?php

class zookeeper_instance extends Zookeeper {
    function connect_cb($type, $event, $string) {
        if ($event == Zookeeper::CONNECTED_STATE) {
            $acl=array(
                "perms"=>0x1f,
                "scheme"=>"world",
                "id"=>"anyone"
            );
        }
    }
}

$zk=new zookeeper_instance();
echo "instance ok\n";

$zk->connect("127.0.0.1:2181", array($zk, 'connect_cb'),200000);
echo "connect ok\n";
$zkm=$zk->get("/hbase/master");
var_dump($zk->getState());
var_dump($zk->getClientId());
var_dump($zk->getAcl("/hbase/master"));
var_dump($zk->getRecvTimeout());
var_dump($zkm);

echo "\n\r";

运行：
php test_zookeeper.php
结果：
instance ok
connect ok
