mongodb-community安装运行遇到的问题

1. 安装

$ brew tap mongodb/brew
$ brew install mongodb-community

2. 运行

$ brew services start mongodb-community
$ mongo

报错：
MongoDB shell version v4.4.1
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn’t connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :

如何排查

1. 查看日志

$ cat /usr/local/var/log/mongodb/mongo.log

2. 日志的内容有个error是权限问题
