grafana

Change Grafana default Username and Password : 

1. Run : sudo nano /etc/grafana/grafana.ini
2. Change the following parameters : 

#################################### Security #################################$
[security]
# default admin user, created on startup
admin_user = tap-your-username

# default admin password, can be changed before first start of grafana,  or in $
admin_password = tap-your-password

When the grafana database is initialized, it uses the informations defined in grafana.ini. That's why you need to alter the database or delete it in order for your modifications to be taken into consideration

This is an example on how to update the grafana database with your new password hash

$ sudo sqlite3 /var/lib/grafana/grafana.db

sqlite> update user set password = '59acf18b94d7eb0694c61e60ce44c110c7a683ac6a8f09580d626f90f4a242000746579358d77dd9e570e83fa24faa88a8a6', salt = 'F3FAxVm33R' where login = 'admin';
sqlite> .exit
