使用mongodb时常发生的几个错误

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

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
