MongoDB错误32-bit servers don't have journaling enabled by default解决方法

时间:2021-05-24

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:

复制代码 代码如下:
**************

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:

复制代码 代码如下:
mongod --auth -dbpath C:\mongo\MongoDB\mongo\data --repair

然后重新启动即可:

复制代码 代码如下:
D:\GREENT~1\PowerCmd>mongod --auth -dbpath C:\mongo\MongoDB\mongo\data
