After mongdb has been installed through brew, the contents of /usr/local/etc/mongod.conf are as follows
systemLog:
destination: file
path: /Users/zyj/database/log/mongodb/mongo.log
logAppend: true
storage:
dbPath: /Users/zyj/database/mongodb
journal:
enabled: true
net:
bindIp: 127.0.0.1
port: 27017
Then start the command line to enter mongod and display
exception in initAndListen: 29 Data directory /data/db not found., terminating
How do I customize the database path
mongod --config /usr/local/etc/mongod.conf
Although you have modified the configuration file, you have not made the configuration file effective. You have to execute the command to make the configuration file effective.
