 修改zabbix-agent配置文件

注：修该主机10.0.0.7的zabbix-agent配置文件

vim /etc/zabbix/zabbix_agentd.conf
修改如下三处：
Server=10.0.0.61,10.0.0.62
ServerActive=10.0.0.61,10.0.0.62
Hostname=10.0.0.7

systemctl start zabbix-agent
systemctl enable zabbix-agent

zabbix部署keepalived

zabbox01安装keepalived

yum install keepalived.x86_64 -y
systemctl start keepalived
systemctl enable  keepalived 

 keepalived配置文件01

cat /etc/keepalived/keepalived.conf
​
! Configuration File for keepalived
global_defs {
router_id LVS_DEVEL 29
}
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 51
priority 150
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
172.16.1.66
}
notify_master /opt/to_master.sh
}
​
systemctl restart keepalived

cat /opt/to_master.sh
​
#!/bin/bash
sshpass -p 123456 ssh -o StrictHostKeyChecking=no root@10.0.0.62 "/etc/init.d/zabbix-server stop"
systemctl start zabbix-server

zabbix02安装keepalived

yum install keepalived.x86_64 -y
systemctl start keepalived
systemctl enable  keepalived 

keepalived配置文件02

cat /etc/keepalived/keepalived.conf
​

​
#!/bin/bash
sshpass -p 123456 ssh -o StrictHostKeyChecking=no root@110.0.0.61 "/etc/init.d/zabbix-server stop"
systemctl start zabbix-server

测试

• 两台zabbix-server都启动keepalived
• zabbix-server01 启动zabbix server
• zabbix-server02 启动zabbix server

zabbix-server01状态如下

zabbix-server02状态如下

模拟zabbix-server01宕机,keepalived
