总结一下如何将mongoDB安装为WinXP下系统服务。
使用的命令如下：
Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.
C:\Documents and Settings\Administrator>mongod -dbpath C:\mongo\MongoDB\mongo\data --logpath=C:\mongo\MongoDB\mongo\logs\mongodb.log --auth --install
all output going to: C:\mongo\MongoDB\mongo\logs\mongodb.log
</div>
但是无法连接：
C:\Documents and Settings\Administrator>mongo
MongoDB shell version: 2.0.1
connecting to: test
Tue May 29 18:07:50 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:8
4
exception: connect failed
</div>
看了一下日志，还需要使用net start MongoDB命令来启动服务，日志如下：
Creating service MongoDB.
Service creation successful.
Service can be started from the command line via 'net start "MongoDB"'.
Tue May 29 18:06:43 dbexit:
Tue May 29 18:06:43 shutdown: going to close listening sockets...
Tue May 29 18:06:43 shutdown: going to flush diaglog...
Tue May 29 18:06:43 shutdown: going to close sockets...
Tue May 29 18:06:43 shutdown: waiting for fs preallocator...
Tue May 29 18:06:43 shutdown: closing all files...
Tue May 29 18:06:43 closeAllFiles() finished
Tue May 29 18:06:43 dbexit: really exiting now
</div>
按照提示，在CMD下运行 net start MongoDB
net start "MongoDB"'
C:\Documents and Settings\Administrator>net start mongoDB
</div>
发生系统错误 2。
系统找不到指定的文件。
通过控制面板–》管理工具–》服务，查看了一下刚才安装的服务：
不知为何mongod命令所在的路径变成了C:\Documents and Settings\Administrator\，如下所示：
"C:\Documents and Settings\Administrator\mongod" -dbpath C:\mongo\MongoDB\mongo\data --logpath=C:\mongo\MongoDB\mongo\logs\mongodb.log --auth --service
</div>
指定好mongod的路径，重新安装：
C:\mongo\MongoDB\mongo\bin>C:\mongo\MongoDB\mongo\bin\mongod -dbpath C:\mongo\MongoDB\mongo\data --logpath=C:\mongo\MongoDB\mongo\logs\mongodb.log --auth --install
all output going to: C:\mongo\MongoDB\mongo\logs\mongodb.log
</div>
这次启动成功了。
