To have launchd start mongodb now and restart at login:
brew services start mongodb
Or, if you don't want/need a background service you can just run:
mongod --config /usr/local/etc/mongod.conf

/usr/local/Cellar/mongodb/4.0.0需要创建一个存放数据的目录，运行
mkdir -p /data/db确保/DATAB/DB目录具有正确的权限：运行
sudo chown -R `id -un` /data/db使用brew 启动和停止
brew services start mongodb
brew services stop mongodb 关闭mongo
db.shutdownServer()如果不想后台启动：
mongod --config /usr/local/etc/mongod.conf
或
mongod --dbpath . # 启动打开一个新的窗口:
mongo出现错误，是因为当前用户没有对存放数据的文件操作的权限 比如 mongod --dbpath /data/db 没有对/data/db 的操作权限
[main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'shutting down with code:100修改权限
sudo chmod -r /data/db
sudo chown -R `id -un` /data/db还是不行,查看一下mongodb.conf 文件，发现
dbPath: /usr/local/var/mongodb
修改试一下,发现可以了
查看mongodb 的端口号
