这里有新鲜出炉的MongoDB教程,程序狗速度看过来!

MongoDB 分布式文件存储的数据库

MongoDB 是一个基于分布式文件存储的数据库。由C++语言编写。旨在为WEB应用提供可扩展的高性能数据存储解决方案。


这篇文章主要介绍了MongoDB错误32-bit servers don't have journaling enabled by default解决方法,需要的朋友可以参考下

每次启动MongoDB时总是会收到如下 Unclean shutdown 提示,总结了一下出现该问题的原因及解决方法。

提示如下:


**************
D:\GREENT~1\PowerCmd>mongod --auth -dbpath C:\mongo\MongoDB\mongo\data
Wed May 16 16:06:50
Wed May 16 16:06:50 warning: 32-bit servers don't have journaling enabled by default. Please use --journal if you want durability.

Wed May 16 16:06:50 [initandlisten] ** NOTE: when using MongoDB 32 bit, you are limited to about 2 gigabytes of data
Wed May 16 16:06:50 [initandlisten] **       see http://blog.mongodb.org/post/137788967/32-bit-limitations
Wed May 16 16:06:50 [initandlisten] **       with --journal, the limit is lower
Wed May 16 16:06:50 [initandlisten]
Wed May 16 16:06:50 [initandlisten] db version v2.0.1, pdfile version 4.5

Wed May 16 16:06:50 [initandlisten] options: { auth: true, dbpath: "C:\mongo\MongoDB\mongo\data" }
**************

*************
Wed May 16 16:06:51 [initandlisten] exception in initAndListen: 12596 old lock file, terminating
Wed May 16 16:06:51 dbexit:

Wed May 16 16:06:51 [initandlisten] closeAllFiles() finished
Wed May 16 16:06:51 dbexit: really exiting now

经过多次测试发现,造成这种情况的原因是我使用PowerCMD启动MongoDB之后直接关掉PowerCMD窗口之后造成的,如果在关闭PowerCMD窗口之前使用 [ctrl + c] 快捷键终止mongod的运行也不会出现此种情况。而且,使用普通的CMD窗口运行mongo命令即使直接关掉窗口也不会出现该问题,看来还是使用原生程序更靠谱。

发生了此种情况解决方法也很简单,使用如下参数repair即可:


mongod --auth -dbpath C:\mongo\MongoDB\mongo\data --repair

然后重新启动即可:


D:\GREENT~1\PowerCmd>mongod --auth -dbpath C:\mongo\MongoDB\mongo\data

还有一些情况会造成这种 Unclean shutdown,解决方法可参考官方文档:
