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
about to fork child process, waiting until server is ready for connections.

错误原因: mongodb非正常关闭删除mongod.lock文件即可.
