Windows下apache+tomcat负载均衡

连接mongodb：

$mongoObj = new Mongo("127.0.0.1" , array(

                        ‘connect‘=>true,

                        ‘persist‘=>true

                    ));

选择库：

$mongoDB = $mongoObj->selectDB("wxdata");

选择集合:

$mongoColletion=$mongoDB->selectCollection("apachelog");

删除一个集合:

$mongoColletion->drop();

插入文档数据：

$mongoColletion->insert(array("firstname" => "Bob", "lastname" => "Jones" ));

修改更新文档数据：

$newdata = array(‘$set‘ => array("address" => "1 Smith Lane"));

$mongoColletion->update(array("firstname" => "Bob"), $newdata);

$mongoColletion->update(

        array("uri" => "/summer_pics"),

        array(‘$inc‘ => array("page hits" => 1)),

        array("upsert" => true)

    );
$mongoColletion->update(

        array("name" => "joe"),

        array("username" => "joe312", "createdAt" => new MongoDate()),

        array("upsert" => true)

    );
$today = array(‘$gt‘ => new MongoDate(), ‘$lt‘ => new MongoDate(strtotime("+1 day")));

$mongoColletion->update(

        array("birthday" => $today),

        array(‘$set‘ => array(‘gift‘ => $surprise)),

        array("multiple" => true)

    );

新增文档数据：

$obj = array(‘x‘ => 1);

$mongoColletion->save($obj);

$obj[‘foo‘] = ‘bar‘;

// $obj 不能被再次插入，导致 duplicate _id 错误

//$mongoColletion->insert($obj);

$mongoColletion->save($obj);

移除一个文档数据：

$mongoColletion->remove(array(‘httpstatus‘ => 200), array("justOne" => true));

统计文档数量：

$mongoColletion->count(array(‘httpstatus‘=>304));

查询一个文档：

$mongoColletion->findOne(array("httpstatus" => 200));

查看文档索引信息：

$mongoColletion->getIndexInfo();

构建文档索引：

// create an index on ‘httpstatus‘ ascending

$mongoColletion->ensureIndex(array(‘httpstatus‘ => 1));

// create a unique index on ‘size‘

$mongoColletion->ensureIndex(array(‘size‘ => 1), array(‘unique‘ => true));

// create a compound index on ‘size‘ ascending and ‘status‘ descending

$mongoColletion->ensureIndex(array(‘size‘ => 1, ‘status‘ => -1));

//全文索引

$mongoColletion->ensureIndex(

        array(

            ‘title‘ => ‘text‘,

            ‘desc‘ => ‘text‘,

        ),

        array(

            ‘name‘ => ‘ExampleTextIndex‘,

            ‘weights‘ => array(

                ‘title‘ => 100,

                ‘desc‘ => 30,

            )

        )

    );

关闭到mongodb的连接：

$mongoObj->close();

从php操作mongodb常用的函数就这么多了。
