The configuration that you create relies on the availability of the target server.
So right after creating the configuration using targetcli, use systemctl enable target on the target server.
On a restart, this service looks for the configuration file /etc/target/saveconfig.json.
If however your server is restarted without the target.service being enabled, and you start it manually later on, it will create a new and empty /etc/target/saveconfig.json.
Fortunately, while working in targetcli, backup configurations are created.
To restore the last working configuration, open the targetcli shell, and from there type the restoreconfig command.
It will show you a list of previously (automatically) saved configurations, from which you only have to load the last working configuration to revert to the previous state.
Yes there is! Just use authconfig –test, and you’ll get an exact overview of everything that is configured regarding authentication.
After logging in to the mysql client, using mysql –u username –p, you’ll get access to the internal documentation. Type help for a generic overview of commands, or type help followed by a specific SQL command to see more details.
For instance, if you want to find out how to use the select command, type help select and you’ll see exactly how to use this command.
