Zabbix 5.0.14 problem after regular Ubuntu 20.04.2 updates
Ok so something happened and I cannot figure out. We have Zabbix 5.0 LTS environment installed on Ubuntu Server 20.04.2 LTS. Everything was fine, 6 months without single problem.
Yesterday after regular weekly updates, after reboot on the server, the front-end web cannot says that the Zabbix server is down.
I check literary everything, from firewall, config files, zabbix_server.service is up, everything seems to be OK !
One strange thing is that, even the zabbix_server.service is UP, I cannot find that the service is listening on 10051 (checking with command: sudo ss -ltn)
Log file /var/log/zabbix/zabbix_server.log prints:
[Z3001] connection to database 'zabbix' failed: [1045] Access denied for user 'zabbix'@'localhost' (using password: NO)
1198:20210721:220441.364 database is down: reconnecting in 10 seconds
I tried granting privileges again: grant all privileges on zabbix.* to zabbix@localhost;
I will appreciate any help and suggestions, this is very weird, and I am desperate !
Thanks !
EDIT:
The problem is solved, compliments to user Spro-ot on Reddit. The solution was increasing the cache_size parameter in zabbix_server.conf file
