zabbix-slave 配置

#zabbix-slave设置

keepalived 获得

[root@zabbix_slave ~]# wget http://www.keepalived.org/software/keepalived-2.0.8.tar.gz

#自动安装脚本

[root@zabbix_slave ~]# cat keepalived_install.sh

#!/bin/bash

pkg=keepalived-2.0.8.tar.gz

tar xf $pkg

yum -y install kernel-devel

ln -s /usr/src/kernels/3.10.0-862.14.4.el7.x86_64/ /usr/src/linux

cd keepalived-2.0.8/

yum install openssl-* gcc-* -y

./configure --prefix=/usr/local/keepalived

make

make install

mkdir -pv /etc/keepalived

cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

ln -s /usr/local/keepalived/sbin/keepalived /sbin/

[root@zabbix_slave ~]# cat /etc/keepalived/keepalived.conf

五、测试

5.1）测试zabbix-server 双机同步情况

通过VIP登录zabbix 添加一个监控机器 然后分别通过zabbix-server的真实IP登录看两个监控平台是否全部都有刚才通过VIP 登录添加的那个机器，确保有就OK

通过VIP登录zabbix修改某个机器的监控项，然后分别通过zabbix-server的真实IP登录看两个监控平台是否全部都有刚才通过VIP 登录修改的那个监控项，确保有就OK

关闭zabbix-server中的master机器，看VIP是否漂移到salve，如果漂移则正确，然后在开启master，开启业务，看slave是否将VIP交出给master，交出并在mater上生效则正常

六、实验问题

问题一 zabbix_get [2480]: Check access restrictions in Zabbix agent configuration

我配置的agent的zabbix服务器为 虚IP地址

成功后发现agent报错

[root@zabbix_master zabbix]# zabbix_get -s 192.168.10.100 -k agent.ping

zabbix_get [2480]: Check access restrictions in Zabbix agent configuration

agent日志 /var/log/zabbix/zabbix_agentd.log

1666:20181215:033150.540 failed to accept an incoming connection: connection from "192.168.10.39" rejected, allowed hosts: "192.168.10.100"

1666:20181215:033202.114 failed to accept an incoming connection: connection from "192.168.10.40" rejected, allowed hosts: "192.168.10.100"

日志中大概能看出原因，agent只接受服务器地址是虚iP，但是通信又是使用的出口网卡的地址，所以拒接了

解决方案 修改server的zabbix server配置文件中的

[root@zabbix_master zabbix]# vim /etc/zabbix/zabbix_server.conf

SourceIP=192.168.10.100

成功了

[root@zabbix_master zabbix]# zabbix_get -s 192.168.10.39 -k agent.ping -I 192.168.10.100

问题二 假报警

仪表盘显示橘黄色的PROGRAM 配置中的host的 主机zabbix状态是红色，但是数据还正常监控中，解决方法是来一次人为的故障切换就好了，

让备当一次主，这样主备监控通道就打通了。
