Configuration File
MaxCtrl reads command-line options from the ~/.maxctrl.cnf configuration file.
The configuration file can be used to store common options, such as the user name and password:
[maxctrl]
user = maxscale
password = secure-password
MaxCtrl will refuse to use the ~/.maxctrl.cnf configuration file if it can be accessed by anyone other than the owner. Ensure that only the owner can access the file using the following command:
$ chown 0600 ~/.maxctrl.cnf
MaxCtrl can use a different configuration file by specifying the -c or --config option:
$ maxctrl --config=/maxscale/maxctrl.cnf \
show services
