Beginning with icinga

• After configuration on puppte master & agent .

• do puppet agent -t on agent machine (This will fetch configuration from master and do the installation ).

if gui is not able to login :

1. check psql -U icingaweb2 -h localhost -d icingaweb2 -W
2. enter password "icingaweb2"
3. if its not able to login then check /var/lib/pgsql/data/pg_hba.conf
4. make sure icinga user is added with md5
5. now restart pgsql ( systemctl restart postgresql.service).
6. again try "psql -U icingaweb2 -h localhost -d icingaweb2 -W" (Now you must be able to login in DB).

1. openssl passwd -1 icingaweb2 (Note down hash key)
2. go into database icingaweb2 => table (icingaweb_user)
