I am new to Ubuntu and Zabbix. I followed all of the steps, but the zabbix server does not start. The server log shows "connection to database zabbix failed: access denied for user zabbix @ localhost". When doing the install, there was an error importing the initial schema and data, and I think that zabbix is not connecting properly to mysql. I believe mysql is running, and there are no errors in the apache logs. When I use a web browser to IPADDRESS/zabbix/stup.php I get a "file not found" page. Sorry I cannot explain the problem better, and thanks for your help.
