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.

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
