问题如下：

[root@localhost bin]# ./mongod -f mongodb.conf &
    [1] 2276
    [root@localhost bin]# warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default
    about to fork child process, waiting until server is ready for connections.
    forked process: 2278
    ERROR: child process failed, exited with error number 100
    
    [1]+  Exit 100                ./mongod -f mongodb.conf

解决办法：
