征服 Mongodb 之 常用命令、基本数据类型

手里有本《MongoDB权威指南》，打算做个读书笔记，把常规命令、数据类型过一遍，强迫记忆。

征服 Mongodb 之 安装与主从配置

关于如何安装、配置、启动MongoDB等，参考上篇文章。

一、常规命令

• 登录

类似于MySQL登录，可参考如下命令：

# mongo --help
MongoDB shell version: 2.0.7
usage: mongo [options] [db address] [file names (ending in .js)]
db address can be:
foo foo database on local machine
192.169.0.5/foo foo database on
192.168.0.5 machine
192.169.0.5:9999/foo foo database on
192.168.0.5 machine on port
9999
options:
--shell run the shell after executing files
--nodb don't connect to mongod on startup - no 'db address' arg expected
--norc will not run the ".mongorc.js" file on start up
--quiet be less chatty
--port arg port to connect to
--host arg server to connect to
--eval arg evaluate javascript
-u [ --username ] arg username for authentication
-p [ --password ] arg password for authentication
-h [ --help ] show this usage information
--version show version information
--verbose increase verbosity
--ipv6 enable IPv6 support (disabled by default)

file names: a list of files to run. files have to end in .js and will exit after unless --shell is specified

# mongo --help
MongoDB shell version: 2.0.7
usage: mongo [options] [db address] [file names (ending in .js)]
db address can be:
  foo                   foo database on local machine
  192.169.0.5/foo       foo database on 192.168.0.5 machine
  192.169.0.5:9999/foo  foo database on 192.168.0.5 machine on port 9999
options:
  --shell               run the shell after executing files
  --nodb                don't connect to mongod on startup - no 'db address' arg expected
  --norc                will not run the ".mongorc.js" file on start up
  --quiet               be less chatty
  --port arg            port to connect to
  --host arg            server to connect to
  --eval arg            evaluate javascript
  -u [ --username ] arg username for authentication
  -p [ --password ] arg password for authentication
  -h [ --help ]         show this usage information
  --version             show version information
  --verbose             increase verbosity
  --ipv6                enable IPv6 support (disabled by default)

file names: a list of files to run. files have to end in .js and will exit after unless --shell is specified

譬如，我经常这么用，一步到位：

# mongo 10.11.20.140/zlex
MongoDB shell version: 2.0.7
connecting to: 10.11.20.140/zlex
>

# mongo 10.11.20.140/zlex
MongoDB shell version: 2.0.7
connecting to: 10.11.20.140/zlex
>
