openvas and redis server problem in sana

root@debain:~# openvas-check-setup
openvas-check-setup 2.3.0
Test completeness and readiness of OpenVAS-8
(add '--v6' or '--v7' or '--9'
if you want to check for another OpenVAS version)

Please report us any non-detected problems and
help us to improve this check routine:
http://lists.wald.intevation.org/mai...penvas-discuss

Send us the log-file (/tmp/openvas-check-setup.log) to help analyze the problem.

Use the parameter --server to skip checks for client tools
like GSD and OpenVAS-CLI.

Step 1: Checking OpenVAS Scanner ...
OK: OpenVAS Scanner is present in version 5.0.1.
OK: OpenVAS Scanner CA Certificate is present as /var/lib/openvas/CA/cacert.pem.
OK: OpenVAS Scanner server certificate is valid and present as /var/lib/openvas/CA/servercert.pem.
OK: NVT collection in /var/lib/openvas/plugins contains 40639 NVTs.
OK: Signature checking of NVTs is enabled in OpenVAS Scanner.
OK: The NVT cache in /var/cache/openvas contains 40639 files for 40639 NVTs.
OK: redis-server is present in version v=2.8.17.
OK: scanner (kb_location setting) is configured properly using the redis-server socket: /var/lib/redis/redis.sock
ERROR: redis-server is not running or not listening on socket: /var/lib/redis/redis.sock
FIX: You should start the redis-server or configure it to listen on socket: /var/lib/redis/redis.sock

ERROR: Your OpenVAS-8 installation is not yet complete!

Please follow the instructions marked with FIX above and run this
script again.
