感觉是此处MongoDB后天没有 运行？
但是要去搞清楚，如何启动MongoDB服务。
如何确保Mac启动时，自动启动MongoDB服务。
参考之前的：
【已解决】给Win中VMWare中macOS安装MongoDB和恢复MongoDB数据
去试试：
brew services enable mongodb-community brew services start mongodb-community
不过先去看看 是不是更新了MongoDB的版本了
~ brew info mongodb-community mongodb/brew/mongodb-community: stable 4.4.3 High-performance, schema-free, document-oriented database https://www.mongodb.com/ /usr/local/Cellar/mongodb-community/4.4.3 (11 files, 156.8MB) * Built from source on 2021-01-18 at 16:35:41 From: https://github.com/mongodb/homebrew-brew/blob/HEAD/Formula/mongodb-community.rb ==> Dependencies Recommended: mongodb-database-tools ✔ ==> Options --without-mongodb-database-tools Build without mongodb-database-tools support ==> Caveats To have launchd start mongodb/brew/mongodb-community now and restart at login: brew services start mongodb/brew/mongodb-community Or, if you don't want/need a background service you can just run: mongod --config /usr/local/etc/mongod.conf
结果：
~ brew services enable mongodb-community Usage: brew services [subcommand] Manage background services with macOS' launchctl(1) daemon manager. If sudo is passed, operate on /Library/LaunchDaemons (started at boot). Otherwise, operate on ~/Library/LaunchAgents (started at login). [sudo] brew services [list]: List all managed services for the current user (or root). [sudo] brew services run (formula|--all): Run the service formula without registering to launch at login (or boot). [sudo] brew services start (formula|--all): Start the service formula immediately and register it to launch at login (or boot). [sudo] brew services stop (formula|--all): Stop the service formula immediately and unregister it from launching at login (or boot). [sudo] brew services restart (formula|--all): Stop (if necessary) and start the service formula immediately and register it to launch at login (or boot). [sudo] brew services cleanup: Remove all unused services. --all Run subcommand on all services. -d, --debug Display any debugging information. -q, --quiet Make some output more quiet. -v, --verbose Make some output more verbose. -h, --help Show this message. Error: Invalid usage: unknown subcommand: enable
没有enable。
mac mongodb-community enable
mac mongodb-community start after boot
说是：
brew services start mongodb-community
中start是：自动开机运行？
而run：
brew services run mongodb-community
只是单次运行？
去start看看
突然注意到：
[sudo] brew services start (formula|--all): Start the service formula immediately and register it to launch at login (or boot).
意思是就是：启动，并且注册服务到开机启动。是我们希望的。
去启动：
~ brew services start mongodb-community Service `mongodb-community` already started, use `brew services restart mongodb-community` to restart.
竟然说是已经启动过了。
那代码中为何不对。
重启试试：
brew services restart mongodb-community Stopping `mongodb-community`... (might take a while) ==> Successfully stopped `mongodb-community` (label: homebrew.mxcl.mongodb-community) ==> Successfully started `mongodb-community` (label: homebrew.mxcl.mongodb-community)
再去运行代码，结果：好像卡死了？？
问题依旧。
mac pymongo.errors.ServerSelectionTimeoutError localhost 27017 Errno 61 Connection refused
brew services start mongodb
的确没有：
~ brew services start mongodb Error: No available formula with the name "mongodb".
去看看当前mongodb状态：
~ brew services Name Status User Plist mongodb-community error xxx /Users/xxx/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
发现是error
Pymongo.errors.serverselectiontimeouterror: localhost:27017: [errno 61] connection refused – Kodlogs
mac mongodb-community status error
去看看mongodb的log
homebrew – brew services start mongodb-community@4.0 fails – uninitialized constant – Stack Overflow
mongod --config /usr/local/etc/mongod.conf
找到：
配置文件：
/usr/local/etc/mongod.conf
去看看
~ cat /usr/local/etc/mongod.conf systemLog: destination: file path: /usr/local/var/log/mongodb/mongo.log logAppend: true storage: dbPath: /usr/local/var/mongodb net: bindIp: 127.0.0.1
去看看db的path：
~ ll /usr/local/var/mongodb total 1175952 -rwxr-xr-x 1 xxx CORP\Domain Users 45B 6 18 2019 WiredTiger -rwxr-xr-x 1 xxx CORP\Domain Users 21B 6 24 2019 WiredTiger.lock -rw------- 1 xxx admin 1.2K 1 22 11:32 WiredTiger.turtle -rwxr-xr-x 1 xxx CORP\Domain Users 276K 1 22 11:32 WiredTiger.wt -rw------- 1 xxx admin 4.0K 1 22 11:32 WiredTigerLAS.wt -rwxr-xr-x 1 xxx CORP\Domain Users 44K 1 22 11:32 _mdb_catalog.wt -rw------- 1 xxx admin 36K 6 3 2020 collection-0--1086966650214792146.wt 。。。
是有数据的。
然后去解决：
【已解决】Mac中MongoDB报错：initandlisten Failed to start up WiredTiger under any compatibility version This may be due to an unsupported upgrade or downgrade
此处是：
brew uninstall mongodb-community brew install mongodb-community@4.2 brew services start mongodb-community@4.2
至少是启动了mongodb。
去试试代码能否运行。
可以了。
【总结】
此处，之前brew不知道何时update或upgrade，导致了
之前的 4.2.1版的 mongodb-community@4.2 被升级到最新的 4.4.3的mongodb-community
导致后续无法正常启动mongodb服务了。
解决办法：
卸载（目前新的，不能用的）：
brew uninstall mongodb-community
重新安装旧的：
brew install mongodb-community@4.2
启动服务：
单次启动是：
brew services run mongodb-community@4.2
启动，并设置为开机启动：
brew services start mongodb-community@4.2
即可。
