Install Gnocchi¶
/ `4 i: c2 V! o1 H$ VInstall the Gnocchi packages. Alternatively, Gnocchi can be install using pip:

! r" r# n& q0 J+ N8 gDepending on your environment size, consider installing Gnocchi separately as it makes extensive use of the cpu.
Create the database for Gnocchi’s indexer:
Use the database access client to connect to the database server as the root user:
$ mysql -u root -p
Create the gnocchi database:
CREATE DATABASE gnocchi;
  v- |1 x2 n: N3 aGrant proper access to the gnocchi database:

# v! w) n* a9 i$ [: g  IDENTIFIED BY 'GNOCCHI_DBPASS';

Replace GNOCCHI_DBPASS with a suitable password.
