Nice write up. Do you enable firewall on all your Debian/ubuntu installs?

Yes, only the necessary ports. So I should add that...

Just changed it, let me know if that is better.

Looking good so far. On step 7 you are missing the letter a in Zabbix.

Ever since I've discovered mysql -e because of @JaredBusch how-to guides, I've been a big fan of using that to create the database and securing the database.

#
mysql -e "CREATE DATABASE zabbix_db;"
mysql -e "CREATE USER 'zabbix_user'@'localhost' IDENTIFIED BY 'password';"
mysql -e "GRANT ALL ON zabbix_db.* TO 'zabbix_user'@'localhost';"
mysql -e "FLUSH PRIVILEGES;"

#
mysql -e "UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';"
mysql -e "DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');"
mysql -e "DELETE FROM mysql.user WHERE User='';"
mysql -e "DROP DATABASE test;"
mysql -e "FLUSH PRIVILEGES;"

Fixed it now.

mysql -e "DELETE FROM mysql.user WHERE User='';"
mysql -e "DROP DATABASE test;"
mysql -e "FLUSH PRIVILEGES;"

So the sudo mysql_secure_installation doesn't do that?

It does, but using mysql -e can help with automating the installation.

I see the point.

I see the point.

And you can probably skip the setup wizard just by adding all those information directly to the zabbix conf file.

I added it prior to the zabbix configuration although it chose to go through the setup.

@dbeato said in Zabbix Server Setup on Debian 9.0:

Prior to doing anytighing if you are basing this on a Debian 9 NetInstall you need to install the following packages as root

apt install ufw sudo -y

Then setup the user in the sudo group

sudo adduser username sudo 

Technically, you do this if you don't select certain packages during the installation. It has nothing to do with it being a NetInstall ISO or not.

Technically, these packages are selected by default. I believe both sudo and ufw are part of standard system utilities.

Additionally ufw is not the firewall. That is iptables, but ufw is the simple way to activate and use iptables.

Yes, netinstall has that option as below Figure 1 while though it does not install ufw and sudo on those standard utilities Figure 2 & 3 with the fresh install Figure 4
