问题
I installed mongodb by brew on my MacOS as the mongodb official documentation, but I tried to run MongoDB manually as a background process, use command "mongod --config /usr/local/etc/mongod.conf --fork". Then the terminal displayed the message is : command not found: mongo.
Did I miss any steps?
回答1:
The above error appears when mongodb executable is not included in the PATH environment variable.
MongoDB gets installed to /usr/local/bin/mongod
The command 'mongod --config /usr/local....' will work only if '/usr/local/bin' is included in PATH.
How to fix the problem?
The problem can be fixed in 2 ways -
- Calling the mongod command with full path
/usr/local/bin/mongod --config /usr/local/etc/mongod.conf --fork
- Adding '/usr/local/bin' to PATH
export PATH=$PATH:/usr/local/bin
Run the above command or add the above line to the end of .zshrc file and .bash_profile file and execute mongodb command in a new terminal window.
mongod --config /usr/local/etc/mongod.conf --fork
