Zabbix监控平台实施方案一、开局、环境准备1二、Zabbix_server监控搭建21/安装LAMP环境及依赖包32/添加用户33/启动mysql，创建数据库，添加用户授权34/编译安装zabbix45/导入数据库，在zabbix的解压文件里导入，导入顺序不能乱46/拷贝、修改配置文件47/添加服务端口58/修改php.Ini59/启动服务510/关闭selinux和iptables611/网页打开http：/6/zabbix6三、zabbix_ agent安装10四、keepalived安装111/安装112/建立启动脚本113/启动keepalived服务124/编辑配置文件125/测试136/脚本14五、mysql主主配置16一、开局、环境准备LAMP（linux+apache+mysql+php）环境搭建及依懒性软件安装安装zabbix-2.4.5.tar.gz安装keepalived-1.2.19.tar.gzMysql主从配置编辑shel脚本，监控服务N:7/24N:9/24Virtual Router:00/24拓补图有两台服务器node1与node2做主备，监控人员只需要登录汇总后的IP地址即可访问zabbix监控服务器上的信息二、Zabbix_server监控搭建安装zabbix需要lamp或者lnmp环境上安装，这里我们选择了lamp，apache相对更加稳定。在安装centos6.5时需要注意的地方系统最小化安装Centos6.5安装好后CRT登录1/安装LAMP环境及依赖包rootnode1 # yum install mysql-server mysql-devel libcurl-devel net-snmp-devel php php-gd php-xml php-mysql php-mbstring php-bcmath httpd y2/添加用户rootnode1 # groupadd zabbixrootnode1 # useradd zabbix -g zabbix -s /sbin/nologin3/启动mysql，创建数据库，添加用户授权rootnode1 # /etc/init.d/mysqld startrootnode1 # mysql -e create database zabbix character set utf8;rootnode1 # mysql -e grant all privileges on zabbix.* to zabbixlocalhost identified by 111111;4/编译安装zabbixrootnode1 # yum install gcc make yrootnode1 # cd /usr/local/src/rootnode1 src# lftp 4lftp 4:/ get zabbix-2.4.5.tar.gzlftp 4:/ exitrootnode1 src# lszabbix-2.4.5.tar.gzrootnode1 src# tar -zxvf zabbix-2.4.5.tar.gzrootnode1 src# cd zabbix-2.4.5rootnode1 zabbix-2.4.5# ./configure -prefix=/usr/local/zabbix -enable-server -enable-agent -with-mysql -with-net-snmp -with-libcurl编辑完zabbix，最后会显示下面的内容* Now run make install * * Thank you for using Zabbix!
