zabbix 3.2高可用

bco

1、架构设计图


2、设计说明
1. 基础架构为LAMP环境，采用keepalived实现zabbix服务器高可用，保证主server的mysql或者httpd宕掉后能切换到从server。
2、数据库做主主同步，保证两边服务器数据的一致性，实现数据库的高可用。
3、采用unison同步软件保证不管修改那台服务器配置，zabbix配置目录及web目录内容的一致，实现文件双向同步。

3、网络环境
zabbix01：192.168.8.117
zabbix02：192.168.8.118
vip：192.168.8.111
4、软件版本
OS：CentOS release 6.9 X86_64
MYSQL:Percona-Server-5.6
NGINX:tengine-2.2.0
PHP: php-7.0.16
ZABBIX:zabbix3.2.6
ZLIB:zlib-1.2.11

5、基础调试
yum update
yum groupinstall '开发工具'
vim /etc/selinux/config
selinux=disabled
:wq
iptables -F
/etc/init.d/iptables save
/etc/init.d/iptables stop
chkconfig iptables off
/etc/init.d/postfix stop && chkconfig postfix off
yum install gcc gcc-c++ libxml2 libxml2-devel libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libmcrypt libmcrypt-devel openssl-devel bzip2-devel recode-devel openldap openldap-devel net-snmp net-snmp-devel libcurl-devel libcurl vim wget ntp jemalloc -y
reboot

chkconfig mysql on
启动服务
/etc/init.d/nginx restart
/etc/ini.d/php-fpm restart

7、安装zabbix（zabbix01和zabbix02相同）
groupadd -g 201 zabbix
useradd -g zabbix -u 201 -s /sbin/nologin zabbix
tar xf zabbix-3.2.6.tar.gz
cd zabbix-3.2.6
./configure --prefix=/usr/local/zabbix --enable-server --enable-proxy --enable-agent --with-mysql=/usr/bin/mysql_config --with-net-snmp --with-libcurl --with-ldap --with-libxml2
make && make install
创建并导入数据（注意顺序）
mysql -e "create database zabbix default charset utf8;"
mysql -e "grant all on zabbix.* to zabbix@localhost identified by 'zabbix';"
mysql -uzabbix -pzabbix zabbix
