After the Coronium SkyTable server is running, you can change the server key which the plugin uses to connect to your instance.

Log in with the coronium user:

ssh coronium@<your-instance-ip>

Enter your password. If you have not updated the password yet, the default is coroniumadmin.

Open the config.lua using the nano file editor:

nano ~/lib/coronium/config.lua

You should see the following content in the config.lua file:

return 
{
  key = "ab34b95ef9cc8b024bd184"
}

Use the arrow keys to move the cursor, and replace the key value, making sure to keep it enclosed in quotes:

return 
{
  key = "12345abcdefg"
}

When your changes have been made, use control-x , then press y, and then press enter, to save the changes.

Reload the underlying nginx process to pick up the new configuration:

sudo monit restart nginx

Close the shell connection with:

exit
