技术之路

vim /etc/yum.repos.d/zabbix.repo

修改两处bashurl

baseurl=http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/6/x86_64/

baseurl=http://mirrors.aliyun.com/zabbix/non-supported/rhel/6/x86_64/

因为zabbix3.0需要php5.4以上，这里安装一个php的yum源

rpm -ivh http://mirror.webtatic.com/yum/el6/latest.rpm

安装httpd和php

yum install httpd -y

yum install php55w php55w-mysql php55w-common php55w-gd php55w-mbstring php55w-mcrypt php55w-devel php55w-xml php55w-bcmath -y

安装zabbix

yum install -y zabbix-agent.x86_64 zabbix-get.x86_64 zabbix-server-mysql.x86_64 zabbix-web.noarch zabbix-web-mysql.noarch

\cp -R /usr/share/zabbix/ /var/www/html/

sed -i 's#^post_max_size = 8M#post_max_size = 16M#g' /etc/php.ini

sed -i 's#^max_execution_time = 30#max_execution_time = 300#g' /etc/php.ini

sed -i 's#^max_input_time = 60#max_input_time = 300#g' /etc/php.ini

sed -i '883a date.timezone = Asia/shanghai' /etc/php.ini

sed -i '276a ServerName 127.0.0.1:80' /etc/httpd/conf/httpd.conf

scp /usr/share/doc/zabbix-server-mysql-3.0.5/create.sql.gz root@192.168.56.99:/opt

在agent上

yum install -y zabbix-agent.x86_64

yum install -y mysql-server mysql-devel mysql

/etc/init.d/mysqld start

mysql -e "create database zabbix character set utf8 collate utf8_bin;"

mysql -e "show databases;"

mysql -e "grant all on zabbix.* to zabbix@'192.168.56.%' identified by '123456';"

mysql -e "select user,host from mysql.user"

zcat /opt/create.sql.gz |mysql -uzabbix -p123456 zabbix

在zabbix-server01上

sed -i '81a DBHost=192.168.56.99' /etc/zabbix/zabbix_server.conf

sed -i '116a DBPassword=123456' /etc/zabbix/zabbix_server.conf

/etc/init.d/httpd start

/etc/init.d/zabbix-server start

/etc/init.d/zabbix-agent start

打开浏览器进行安装

安装完成后

scp /etc/zabbix/web/zabbix.conf.php root@192.168.56.30:/opt

在zabbix-server02

rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm

vim /etc/yum.repos.d/zabbix.repo

修改两处bashurl

baseurl=http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/6/x86_64/

baseurl=http://mirrors.aliyun.com/zabbix/non-supported/rhel/6/x86_64/

rpm -ivh http://mirror.webtatic.com/yum/el6/latest.rpm

安装httpd和php

yum install httpd -y

yum install php55w php55w-mysql php55w-common php55w-gd php55w-mbstring php55w-mcrypt php55w-devel php55w-xml php55w-bcmath -y

安装zabbix

yum install -y zabbix-agent.x86_64 zabbix-get.x86_64 zabbix-server-mysql.x86_64 zabbix-web.noarch zabbix-web-mysql.noarch

\cp -R /usr/share/zabbix/ /var/www/html/

sed -i 's#^post_max_size = 8M#post_max_size = 16M#g' /etc/php.ini

sed -i 's#^max_execution_time = 30#max_execution_time = 300#g' /etc/php.ini

sed -i 's#^max_input_time = 60#max_input_time = 300#g' /etc/php.ini

sed -i '883a date.timezone = Asia/shanghai' /etc/php.ini

sed -i '276a ServerName 127.0.0.1:80' /etc/httpd/conf/httpd.conf

sed -i '81a DBHost=192.168.56.99' /etc/zabbix/zabbix_server.conf

sed -i '116a DBPassword=123456' /etc/zabbix/zabbix_server.conf

\mv /opt/zabbix.conf.php /etc/zabbix/web/

/etc/init.d/httpd start

vi /etc/zabbix/zabbix_agentd.conf

修改如下三处：

Server=192.168.56.30,192.168.56.29

ServerActive=192.168.56.30,192.168.56.29

Hostname=192.168.56.99

修改完成如下

/etc/init.d/zabbix-agent start

在zabbix-server01和zabbix-server02上分别安装keepalived的

zabbix-server01

配置文件如下

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 {

192.168.56.66

}

notify_master /opt/to_master.sh

}

cat /opt/to_master.sh

#!/bin/bash

sshpass -p 123456 ssh -o StrictHostKeyChecking=no root@192.168.56.30 "/etc/init.d/zabbix-server stop"

/etc/init.d/zabbix-server start

zabbix-server02

配置文件如下

cat /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

router_id LVS_DEVEL 30

}

vrrp_instance VI_1 {

state BACKUP

interface eth0

virtual_router_id 51

priority 100

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

192.168.56.66

}

notify_master /opt/to_master.sh

}

[root@zabbix3 zabbix]# cat /opt/to_master.sh

#!/bin/bash

sshpass -p 123456 ssh -o StrictHostKeyChecking=no root@192.168.56.29 "/etc/init.d/zabbix-server stop"

/etc/init.d/zabbix-server start

下面是测试

两台zabbix server都启动keepalived的

zabbix-server01 启动zabbix server

zabbix-server02不启动zabbix server

zabbix-server01状态如下

zabbix-server02状态如下

模拟zabbix-server01宕机，keepalived不工作了

再测试飘回来

查看数据历史间隔，发现会丢失个别监控项的一次监控数据

由于两台zabbix-server只会同时开启一台，所有agent的日志如下

期待你有更好的方法！
