双主安装文档

1、 Zabbix 高可用方案实施拓扑图准备环境：1、server1 安装zabbix，mysql，php，nginx ,keepalived 确保zabbix能够正常服务第一步ok，肯定都是有在跑着的zabbix服务的。这里不介绍zabbix的安装，可参考我zabbix安装的文档2、准备server2环境：（1）安装php、nginx、mysql、zabbix,keepalived（2）备份server1数据库导入到server2数据库中（3）server1和server2 数据库做主主同步（全库同步）（3）cp server1 web文件到server2 web目录中。（4）启动所有服务，打开

2、浏览器登录zabbix，确保zabbix能够正常访问。1 安装 安装依赖包 yum install -y gcc gcc-c+ pcre-devel openssl-devel epel-release libxml2-devel libevent-devel php-fpm php-common php-devel php-mbstring php-mcrypt php php-mysql php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-bcmath mysql-connector-odbc libdbi-dbd-my
