Mongodb常见错误与解决方法小结(Mongodb中经常出现的错误)
今天在配置MongoDB时发生了以下几个错误, 已经被我解决了,提供给大家.
2015-05-12T09:30:26.313+0800 I STORAGE [initandlisten] exception in initAndListen: 28574 Cannot start server. Detected data files in /root/Desktop/mongodb/data created by storage engine 'mmapv1'. The configured storage engine is 'wiredTiger'., terminating
2015-05-12T09:30:26.313+0800 I CONTROL [initandlisten] dbexit: rc: 100
2015-05-12T09:31:53.043+0800 I CONTROL ***** SERVER RESTARTED *****
2015-05-12T09:31:53.049+0800 I STORAGE [initandlisten] exception in initAndListen: 28574 Cannot start server. Detected data files in /root/Desktop/mongodb/data created by storage engine 'mmapv1'. The configured storage engine is 'wiredTiger'., terminating
2015-05-12T09:31:53.050+0800 I CONTROL [initandlisten] dbexit: rc: 100
补充一下:如果存储空间满了的话也会出现 rc:100错误。总线一下:rc:100是系统文件错误
错误原因: 之前使用mmapv1创建的数据库不能使用wiredTiger打开,需要重新指定dbpath
[root@localhost Desktop]# Python mongodb.py

ERROR: child process failed, exited with error number 100
ERROR: child process failed, exited with error number 100
ERROR: child process failed, exited with error number 100
错误原因: mongodb非正常关闭 删除mongod.lock文件即可.
ERROR: child process failed ,exited with error number 1
错误原因: dbpath文件的权限问题,增加写权限即可
mongodb.conf bind 不能写127.0.0.1否则其它主机连接不了
情况不唯一,这边只能当参考,大致就是这么几种解决思路
child process failed, exited with error number 1
child process failed, exited with error number 48
child process failed, exited with error number 100
前今天装了MongoDB后,今天早上启动服务的时候启动不了了,出现错误如下:
错误:
错误2:系统找不到指定文件
思考过程:
昨天做测试的时候,先后安装了两次MongoDB,后来我又删除(注意不是卸载)了一个MongoDB文件夹,当前这个服务是不是默认的MongoDB的安装地址错误呢?
查看服务属性,Mongo的地址是已经删除了的个地址,而不是当前我用的这个地址。当前用的地址是:E:\Program files\mongodb\bin
解决方式:
先卸载原来的安装,再次安装新的。
Mongo卸载:
卸载:mongod.exe --remove --serviceName "MongoDB"
MongoDB安装为服务:
安装:mongod.exe --install --logpath="E:\Program files\mongodb\data\log\log.txt" --dbpath="E:\Program files\mongodb\data\db"
安装后刷新服务,地址改变:
再次启动MongoDB服务,启动失败,出现1607错误。
错误:
错误原因:不明
解决方式:
删除E:\Program files\mongodb\data\db目录下的mongod.lock文件。
再次重启服务,启动成功。
总结:
接触一个新的东西的时候,难免出现错误,错误来了,就解决,不要躲着,拖着。
