zabbix 使用进阶（六）
===============================================================================概述
===============================================================================
zabbix proxy：
---可选组件，常用于分布式监控环境中，代理Server收集部分被监控数据并统一发往Server端；
★安装配置过程：
(1)准备数据库服务器；
(2)安装
zabbix-proxy-mysql-3.0.2-1.el7.x86_64.rpmzabbix-get-3.0.2-1.el7.x86_64.rpm
(3)生成数据库
sql脚本位置：/usr/share/doc/zabbix-proxy-mysql-3.0.2/schema.sql.gz
mysql zabbix_proxy < /usr/share/doc/zabbix-proxy-mysql-3.0.2/schema.sql
(4)配置启动；
(5)在server端添加此proxy；
(6)添加hosts时，选择使用指定的proxy进行监控；
演示：
操作环境：新添加一台CentOS 7.2-4的虚拟主机配置zabbix-proxy，然后代理server端监控CentOS 7.2-3 主机；
-----------------------------------------------------------------------------------------
1.设置zabbix database，创建一个数据库，并授权一个用户有权限连接并使用zabbix-proxy的数据库
1)mariadb安装，配置，及启动

# 在CentOS 7 安装mariadb数据库，使用前要首先编辑其配置文件/etc/my.cnf,添加跳过名称解析等
# vim /etc/my.cnf
skip_name_resolve = ON
innodb_file_per_table = ON
# 启动数据库，可以设置开机自启动
# systemctl start mariadb.service
# systemctl enabled mariadb.service
2）创建zabbix database数据库，并授权一个用户可以远程和本地登录此数据库；

2.安装服务器端
1）下载zabbix相关的所有程序包
# ls zabbix-proxy
zabbix-get-3.0.2-1.el7.x86_64.rpmzabbix-proxy-mysql-3.0.2-1.el7.x86_64.rpm
2）安装server端的程序包：zabbix-server-mysql和zabbix-get
# yum install zabbix-proxy-mysql-3.0.2-1.el7.x86_64.rpm zabbix-get-3.0.2-1.el7.x86_64.rpm -y
# rpm -ql zabbix-proxy-mysql

4.zabbix-proxy配置启动
1）配置说明
# grep "^####" /etc/zabbix/zabbix_proxy.conf //获取配置段大概信息
############ GENERAL PARAMETERS #################
######### PROXY SPECIFIC PARAMETERS #############
############ ADVANCED PARAMETERS ################
####### LOADABLE MODULES #######
####### TLS-RELATED PARAMETERS #######
2）编辑配置如下：
# vim /etc/zabbix/zabbix_proxy.conf
Server=
Hostname=zbxproxy.CentOS7.2-4
DBHost=
DBName=zabbix_proxy
DBUser=zbxproxy
DBPassword=zbxpass
ConfigFrequency=120 //zabbix-server端多长时间将proxy配置推送给proxy端
DataSenderFrequency=1 //proxy端每多长时间把数据发送给zabbix-server端
3)启动zabbix-proxy服务，查看端口10051
---------------------------------------------------------------------------------------
5.在server端添加此proxy
6.添加hosts时，选择使用指定的proxy进行监控；
