刚装好mongodb启动报错如下:
root@inspur-CE3000F:/usr/local/mongodb# /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 8485
ERROR: child process failed, exited with error number 48
To see additional information in this output, start without the "--fork" option.
解决方法：
- 首先删除
data以及log里面生成的所有文件
root@inspur-CE3000F:/usr/local/mongodb# cd data/
root@inspur-CE3000F:/usr/local/mongodb/data# ll
总用量 168
