●zabbix The stored database table structure is slightly complex, but the logic is clear

●zabbix There is Concept of template , It's convenient to put - Deploy group monitoring items （ For example, we have many zabbix Server side , If we were in a machine a It defines 100 Monitoring content , We're working on the machine b If so many monitoring contents need to be defined in, we don't need to redefine them , Just put the machine a Export the monitoring template of to the machine b Can ）

Four 、zabbix Installation

zabbix The official download ： download Zabbix

1、 Prepare a new machine , Environment initialization

zabbix The machine memory should be large enough ,4G Just fine .

Know the name of the device and take it out ip Address
