8. ZABBIX distributed

Distributed

zabbix proxy Can replace zabbix server Collect performance and availability data , And then report the data to zabbix server, And to some extent, they share zabbix server The pressure of the . Besides , When all agents and proxies Report to a Zabbix server And when all the data is collected centrally , Use proxy Is the simplest way to achieve centralized and distributed monitoring

zabbix proxy Use scenarios ：

• Monitoring remote area equipment
• Monitor local network instability areas
• When zabbix When monitoring thousands of devices , Use it to reduce server The pressure of the , Achieve load balancing
• Simplify the maintenance of Distributed Monitoring

# Environmental Science 
server 5.4
proxy  5.5
agent  5.6

# Firewall OFF , Turn off autodiscover , Automatic registration 
systemctl stop firewalld

# The server needs no operation , The default installation is enough 

#agent2 End default installation 

#proxy If installed agent2, close 
systemctl stop zabbix-agent2

# To configure proxy The server , Deploy proxy, Deploy database , If Alibaba cloud is not configured zabbix Source , Then configure , Refer to installation
