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

我的日志：

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”不是吗？

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]

是否有其他进程正在侦听这些端口？尝试找出：

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

如果您确定不需要它，请终止该过程。正如 Lix 在下面回答的那样，可能已经有一个 mongo 进程正在运行。

答案就在日志文件中：

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

具体这部分："Address already in use for socket: 127.0.0.1:28017"

似乎已经在该默认端口 27017 上运行了一个 mongo 实例。它甚至可能不是一个 mongo 实例，而是使用该端口的其他一些应用程序。

根据日志，很明显还有另一个默认运行的 mongodb 实例，我相信您使用 rpm 安装了 mongodb 并使用 service mongodb start 启动了此服务。因此，默认情况下，当服务器重新启动时，它会启动一些服务，使用将在 /etc/mongod.config 中可用的默认配置编辑此文件或停止已经运行的文件，这样您就可以避免使用 mongod 默认实例并制作您的版本启动并运行
