Unable to get Agent running on Server

[GrumpyZAF]

I am very new to zabbix and I am trying to get it running on an Azure VM running Ubuntu 18.04.

Managed to get everything setup and installed, on the front end I am unable to connect to the server.

Here is the snippets from the log files.

You have two separate (unrelated) problems:

11110:20201119:144604.159 [Z3001] connection to database 'zabbix' failed: [1045] Access denied for user 'zabbix'@'localhost' (using password: NO)
11110:20201119:144604.159 database is down: reconnecting in 10 seconds

Your zabbix_serverd process cannot access the database. You need to review the database setup, make certain you've followed all the steps for setting up and that the /etc/zabbix/zabbix_server.conf has the right configuration for connecting to your database. If the zabbix_serverd processes can't connect to the database, not much is going to work.

Agent

43605:20201119:103742.394 active check configuration update from [127.0.0.1:10051] started to fail (cannot connect to [[127.0.0.1]:10051]: [111] Connection refused)

43600:20201119:111539.625 Got signal [signal:15(SIGTERM),sender_pid:62415,sender_uid:111 ,reason:0]. Exiting ...

That says that your agent can't get a list of what active checks it should be running because the zabbix_serverd has the first problem (described above). Then, the agent exits with SIGTERM, which is probably intentional, but I would have to look at the code to be certain.

Get your zabbix_serverd fixed up so that it's running and working, then restart your agent to see if the problem goes away once the server is functional
