Create zabbix database and set permissions:

sudo mysql -e"create database zabbix;"

sudo mysql -e"grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';"

Populate the database (the order you do this matters):

mysql -D zabbix -uzabbix -pzabbix < /home/zabbix/zabbix-1.9.1/create/schema/mysql.sql

mysql -D zabbix -uzabbix -pzabbix < /home/zabbix/zabbix-1.9.1/create/data/images_mysql.sql

mysql -D zabbix -uzabbix -pzabbix < /home/zabbix/zabbix-1.9.1/create/data/data.sql

Configure, compile and install the server:

cd zabbix-1.9.1/

./configure --prefix=/usr --with-mysql --with-net-snmp --with-libcurl --with-jabber=/usr/ --enable-server --enable-agent

make

sudo make install

Setup the rest of the system:
Configure services:

sudo vi /etc/services

Add the following to the end:

zabbix_agent 10050/tcp # Zabbix ports

zabbix_trap 10051/tcp

Save and exit.

sudo mkdir /etc/zabbix

sudo chown -R zabbix.zabbix /etc/zabbix/

cp misc/conf/zabbix_* /etc/zabbix/

Edit the server configuration file:

sudo vi /etc/zabbix/zabbix_server.conf

Set these two lines as shown ( uncomment DBPassword ):

DBUser=zabbix

DBPassword=zabbix

Save and exit.

Copy the init scripts:

sudo cp misc/init.d/debian/zabbix-server /etc/init.d

sudo cp misc/init.d/debian/zabbix-agent /etc/init.d

Edit the server init script:

sudo vi /etc/init.d/zabbix-server

Change the line:

DAEMON=/usr/local/sbin/${NAME}

So it reads (remove the /local):

DAEMON=/usr/sbin/${NAME}

Edit the agent init script:

sudo vi /etc/init.d/zabbix-agent

Change the line:

DAEMON=/usr/local/sbin/${NAME}

So it reads (remove the /local):

DAEMON=/usr/sbin/${NAME}

Set the correct permissions on the init scripts and set to start at boot:

o chmod 755 /etc/init.d/zabbix-agent

sudo sudo chmod 755 /etc/init.d/zabbix-serversudo update-rc.d zabbix-server defaultssudupdate-rc.d zabbix-agent defaults

Start the server and agent:

sudo /etc/init.d/zabbix-server start

sudo /etc/init.d/zabbix-agent start

See if they are running:

ps -aux | grep zabbix

You should see zabbix-server and zabbix-agent multiple times if everything went ok.

mkdir /home/zabbix/public_html

cp -R frontends/php/* /home/zabbix/public_html/
