当我尝试使用“mongod”命令（在Macintosh上）启动mongo时出现错误。

all output going to: /usr/local/var/log/mongodb/mongo.log

更新：

当我执行“mongo”命令时：

MacBook-Pro-de-Anthony:Sites anthonycluse$ mongo
MongoDB shell version: 2.4.4
connecting to: test
Server has startup warnings: 
Tue Oct 29 11:43:15 [initandlisten] 
Tue Oct 29 11:43:15 [initandlisten] ** WARNING: soft rlimits too low. Number of files is 256, should be at least 1000
> show dbs;
anthonycluse    (empty)
local   (empty)
>

这意味着用户名是“test”no？

更新2：

“显示用户”;命令：

MacBook-Pro-de-Anthony:Sites anthonycluse$ mongo
MongoDB shell version: 2.4.4
connecting to: test
Server has startup warnings: 
Tue Oct 29 11:43:15 [initandlisten] 
Tue Oct 29 11:43:15 [initandlisten] ** WARNING: soft rlimits too low. Number of files is 256, should be at least 1000
> show users;

Answer 1

是否还有另一个进程侦听这些端口？尝试找出：

netstat -tulpen | grep 017 # 017 for both port 27017 and 28017

如果您确定不需要，请终止该过程。如下面Lix所述，可能已经有一个mongo进程在运行。

Answer 2

答案就在日志文件旁边：

Tue Oct 29 13:15:48.801 [websvr] ERROR: listen(): bind() failed errno:48 Address already in use for socket: 127.0.0.1:28017

特别是这部分："Address already in use for socket: 127.0.0.1:28017"

似乎已经在默认端口27017上运行了mongo实例。它甚至可能不是mongo实例，而是使用该端口的其他应用程序。

Answer 3

根据日志很明显，默认情况下运行另一个mongodb实例，我相信您使用rpm安装了mongodb并使用服务mongodb start启动了此服务。因此，当服务器默认重启时，它会启动一些服务，使用defaultconfiguration，可以在/etc/mongod.config中编辑这个文件或者停止已经运行的文件，这样你就可以避免mongod默认instamce并制作你的版本了启动并运行

启动mongo失败
