【问题描述】：

我运行mongo 并得到输出：

MongoDB shell version v4.4.1
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("446d44ce-8342-40ec-a308-667a28ce10a0") }
MongoDB server version: 4.4.1

The server generated these startup warnings when booting: 
        2020-12-16T20:36:30.592-03:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted

        Enable MongoDB's free cloud-based monitoring service, which will then receive and display
        metrics about your deployment (disk utilization, CPU, operation statistics, etc).

        The monitoring data will be available on a MongoDB website with a unique URL accessible to you
        and anyone you share the URL with. MongoDB may use this information to make product
        improvements and to suggest MongoDB products and deployment options to you.

        To enable free monitoring, run the following command: db.enableFreeMonitoring()
        To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

在另一个终端我运行mongod 并得到：

但我没有看到“等待端口 27017 上的连接”消息。我尝试了我在互联网上找到的所有内容！我安装了自制软件来安装 MongoDB。

【问题讨论】：

另外，当我输入命令 ~ % brew services list 时，它会返回错误消息
mongodb-community error myname /Users/myname/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
mongodb-community@4.2 错误我的名字 /usr/local/opt/mongodb-community@4.2/homebrew.mxcl.mongodb-community@4.2.plist

标签： mongodb macos homebrew macos-catalina

【解决方案1】：

从运行mongo 得到的输出中，我们可以看到您能够成功连接到预先存在的mongod 进程。当您尝试运行mongod 时，会出现一条说明Address already in use 的日志，支持已经有mongod 进程在运行的想法。我不清楚您遇到了什么问题。
