Zabbix Agent Install
This page provide basic instructions for installing Zabbix Agent 3.0 LTS from source on OpenSUSE 42.3. Will probably work on more versions.
Add user and group
First add user and group to run the zabbix-agent as.
Note: run this as root (sudo -i) or add sudo in front of every command.
groupadd zabbix
useradd -g zabbix zabbix
Install dependencies
Install dependencies to be able to compile the source
zypper in gcc-c++ libopenssl-devel make
Download source
Download the source from Zabbix.com under "Zabbix Sources" (https://www.zabbix.com/download)
wget https://downloads.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.0.10/zabbix-3.0.10.tar.gz
and the extract it.
tar xvf zabbix-3.0.10.tar.gz
and enter that directory.
Compiling
Start to compile
./configure --enable-agent --with-openssl
After the exited without any errors
make install
Edit the configuration
Edit the Zabbix-agent configuration file to suit your setup.
Here i will set it up as an active only agent with Pre-Shared-Key as encryption.
vim /usr/local/etc/zabbix_agentd.conf
Change/add/uncomment the following:
- LogFile=/var/log/zabbix/zabbix_agentd.log - Server=<zabbix server> - StartAgents=0 - ServerActive=<zabbix server> - Hostname=<hostname> - User=zabbix - TLSConnect=psk - TLSAccept=psk - TLSPSKIdentity=<hostname> - TLSPSKFile=/usr/local/etc/zabbix_agentd.psk
Create the .psk file.
openssl rand -hex 32 > /usr/local/etc/zabbix_agentd.psk
We moved the location of logfile, so we need to create a folder for it
mkdir /var/log/zabbix chown root:zabbix /var/log/zabbix chmod 775 /var/log/zabbix
Add SystemD startup
Create the systemd .service file
vim /etc/systemd/system/zabbix-agentd.service
Enter this:
[Unit] Description=Zabbix Agent 3.0 LTS After=syslog.target After=network.target [Service] Environment="CONFFILE=/usr/local/etc/zabbix_agentd.conf" EnvironmentFile=-/etc/sysconfig/zabbix-agent Type=forking Restart=on-failure KillMode=control-group ExecStart=/usr/local/sbin/zabbix_agentd -c $CONFFILE ExecStop=/bin/kill -SIGTERM $MAINPID RestartSec=10s [Install] WantedBy=multi-user.target
Reload daemons, enable and start
systemctl daemon-reload systemctl enable zabbix-agentd systemctl start zabbix-agentd
Check that the service is running OK
tail /var/log/zabbix/zabbix_agentd.log
Should look something like this
Starting Zabbix Agent [<hostname>]. Zabbix 3.0.10 (revision 70208). **** Enabled features **** IPv6 support: NO TLS support: YES ************************** using configuration file: /usr/local/etc/zabbix_agentd.conf agent #0 started [main process] agent #2 started [active checks #1] agent #1 started [collector]
