daemon启动

mongod命令默认是运行在前台，将输出等全部打印在前台
我们新建配置文件/usr/local/etc/mongodb.conf

port=27017
dbpath=/data/db
logpath=/data/log/mongodb.log
logappend=true
fork=true

以配置文件启动

mongod --config mongodb.conf
可能会出现下面的错误

about to fork child process, waiting until server is ready for connections.
forked process: 3413
ERROR: child process failed, exited with error number 1
To see additional information in this output, start without the "--fork" option.

这样的错误一般情况下是因为权限问题，这里以sudo启动: sudo mongod --config mongodb.conf
返回下面信息代表启动成功 :

about to fork child process, waiting until server is ready for connections.
forked process: 3430
child process started successfully, parent exiting
