使用官网下载的mongodb，如何设置远程连接mongodb服务器

在linux到官网下载mongodb，选择64位版本。
解压后在mongo的bin目录下运行 mongod --dbpath ~/mongo/db
可以看到mongodb服务被正常启动了。
 
在局域网其他电脑上使用mongodb客户端尝试连接这个mongo服务器，发现无法连接上。
因为官网下载的mongo问价解压后并没有mongo.conf配置文件。
 
在本机运行命令： mongo
可以看到输出：

从上面的信息可以看到，如果需要远程的机子连接到本机，需要添加一个选项： --bind_ip_all
运行下面命令后：
mongod --dbpath ~/mongo/db --bind_ip_all
 
远程的机子就能够连上mongo服务器了。
