virtualbox下 共享目录权限导致：npm ERR! ETXTBSY, rename ‘/home/vagrant/.npm/….

解决办法：

npm config set cache /var/.npm

直接修改缓存目录
npm config edit

运行yum命令查看MongoDB的包信息

um info mongo-10gen

（提示没有相关匹配的信息，） 说明你的centos系统中的yum源不包含MongoDB的相关资源，所以要在使用yum命令安装MongoDB前需要增加yum源，也就是在 /etc/yum.repos.d/目录中增加 *.repo yum源配置文件

vi /etc/yum.repos.d/10gen.repo，输入下面的语句：

[10gen]

name=10gen Repository

baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64

gpgcheck=0

做好yum源的配置后，如果配置正确执行下面的命令便可以查询MongoDB相关的信息：

查看mongoDB的服务器包的信息

yum info mongo-10gen-server

安装MongoDB的服务器端和客户端工具

yum install mongo-10gen-server

yum install mongo-10gen

centos6.4 默认源，163源都不给力

安装Atomic源

wget -q -O – http://www.atomicorp.com/installers/atomic | sh

地理位置索引支持是MongoDB的一大亮点，这也是全球最流行的LBS服务foursquare 选择MongoDB的原因之一。我们知道，通常的数据库索引结构是B+ Tree，如何将地理位置转化为可建立B+Tree的形式，下文将为你描述。

首先假设我们将需要索引的整个地图分成16×16的方格，如下图（左下角为坐标0,0 右上角为坐标16,16）：

单纯的［x，y］的数据是无法建立索引的，所以MongoDB在建立索引的时候，会根据相应字段的坐标计算一个可以用来做索引的hash值，这个值叫做geohash，下面我们以地图上坐标为［4，6］的点（图中红叉位置）为例。

我们第一步将整个地图分成等大小的四块，如下图：

划分成四块后我们可以定义这四块的值，如下（左下为00，左上为01，右下为10，右上为11）：

这样［4，6］点的geohash值目前为 00

然后再将四个小块每一块进行切割，如下：

这时［4，6］点位于右上区域，右上的值为11，这样［4，6］点的geohash值变为：0011

继续往下做两次切分：

最终得到［4，6］点的geohash值为：00110100

这样我们用这个值来做索引，则地图上点相近的点就可以转化成有相同前缀的geohash值了。

我们可以看到，这个geohash值的精确度是与划分地图的次数成正比的，上例对地图划分了四次。而MongoDB默认是进行26次划分，这个值在建立索引时是可控的。具体建立二维地理位置索引的命令如下：

db.map.ensureIndex({point : "2d"}, {min : 0, max : 16, bits : 4})

其中的bits参数就是划分几次，默认为26次。

Bucardo 是一个用 Perl 语言编写的 PostgreSQL的多Master节点复制系统
它支持任意方式的同步，以下是同步到mongodb的说明
参考：http://blog.endpoint.com/2011/06/mongodb-replication-from-postgres-using.html

有两种方式构建软件设计：一种是把软件做得很简单以至于明显找不到缺陷；另一种是把它做得很复杂以至于找不到明显的缺陷。

一个人，一定要想清楚自己五年后要做什么，不要只看着眼前。

基础应用

1.创建地图： var map = new BMap.Map(“divid”);

2.创建坐标点：var point = new BMap.Point(“经度”,”纬度”);

3.设置视图中心点：map.centerAndZoom(point,size);

4.激活滚轮调整大小功能：map.enableScrollWheelZoom();

5.添加控件：map.addControl(new BMap.Xxx());

6.添加覆盖物：map.addOverlay();

控件介绍

1.NavigationControl：缩放地图的控件，默认在左上角；

2.OverviewMapControl：地图的缩略图的控件，默认在右下方；

3.ScaleControl：地图显示比例的控件，默认在左下方；

4.MapTypeControl：地图类型控件，默认在右上方；

map.addControl()方法添加控件；

1.标注：Marker

(1)在point处添加标注：var marker = new BMap.Marker(point);

(2)添加覆盖物：map.addOverlay(marker);

(3)激活标注的拖拽功能：marker.enableDragging();

(4)为标注添加事件：marker.addEventListener(“名称”,function(){

//点击标注后的事件

});

(5)删除覆盖物：map.removeOverlay(marker);

(6)销毁标注：marker.dispose();

2.信息窗口：InfoWindow

(1)在某个特定的位置创建一个信息窗口：var infowindow = new BMap.InfoWindow(“内容”,{width:250,height:100,title:”hello”});

(2)在地图中央打开信息窗口：map.openInfoWindow(infoWindow,map.getCenter());
