Debian Wheezy

• Per Wheezy l'ultima release disponibile è la 3.4:

 cd /tmp  && \
 wget https://repo.zabbix.com/zabbix/3.4/debian/pool/main/z/zabbix-release/zabbix-release_3.4-1+wheezy_all.deb

• Se non va con wget, usare curl

cd /tmp  &&  curl -O -J https://repo.zabbix.com/zabbix/3.4/debian/pool/main/z/zabbix-release/zabbix-release_3.4-1+wheezy_all.deb

• Se si usa un proxy:

--proxy http://user:password@1.2.3.4:3128

• Se curl non è installato, instalallarlo
• Se non si installa

wget http://archive.debian.org/debian/pool/main/c/curl/curl_7.26.0-1+wheezy13_i386.deb
wget http://archive.debian.org/debian/pool/main/c/curl/libcurl3_7.26.0-1+wheezy13_i386.deb
dpkg -i libcurl3_7.26.0-1+wheezy13_i386.deb
apt-get install curl

• Installare zabbix

 dpkg -i zabbix-release_3.4-1+wheezy_all.deb && \
 sudo apt-get update && \
 sudo apt-get install zabbix-agent

Configurazione

• Configurare i parametri:

export SRV=192.168.10.254
export HST=myserver.example.priv

sed -i -e "s/^Server=127.0.0.1/Server=${SRV}/" /etc/zabbix/zabbix_agentd.conf
sed -i -e "s/^ServerActive=127.0.0.1/ServerActive=${SRV}/" /etc/zabbix/zabbix_agentd.conf
sed -i -e "s/^Hostname=Zabbix server/Hostname=${HST}/" /etc/zabbix/zabbix_agentd.conf

• Verificare

sudoedit /etc/zabbix/zabbix_agentd.conf

Server=192.168.6.254                 # Internal IP of Zabbix Server/Proxy
ServerActive=192.168.6.254           # Internal IP of Zabbix Server/Proxy
Hostname=internal-host.example.priv  # Name of internal host as defined on zabbix server

• Abilitare il servizio:

sudo systemctl enable zabbix-agent.service
sudo systemctl restart zabbix-agent.service
sudo systemctl status zabbix-agent.service

• Per Wheezy

/etc/init.d/zabbix-agent restart
/etc/init.d/zabbix-agent  status

• Definire l'host sul server Zabbix, assegnandolo al proxy precedentemente creato

• Attendere circa 5 minuti, che il server invii i dettagli di configurazione al proxy.
