MongoDB入门

MongoDB安装

Ubuntu 14.04下默认安装版本为2.4.9

$ sudo apt-get install mongodb

连接数据库：

$ mongo

默认会通过本地连接（127.0.0.1）到数据库test

查看MongoDB版本：mongo -version

数据库地址：/var/lib/mongodb

日志地址：/var/log/mongodb/mongodb.log

这些地址均在配置文件里设定

配置远程连接
配置文件里默认是：bind_ip = 127.0.0.1 （只能本地连接）
bind_ip = 0.0.0.0 （所有IP地址均可连接）
bind_ip = 192.168.235.1，192.168.235.2（多个IP用英文逗号隔开）

认证和访问控制
MongoDB的认证默认是关闭的，也就是所有人都可以访问MongoDB中所有的数据库。
