## 一、简介 ##

zabbix proxy可以代替zabbix server检索客户端的数据，然后把数据汇报给zabbix server，并且在一定程度上分担了zabbix server的压力。对于多机房大集群情况下，肯定不是一台zabbix server服务器来进行信息的收集等工作，所以就要用到代理了。zabbix proxy可以非常简便的实现了集中式、分布式监控。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70]  
zabbix-server 处于外网，zabbix-agent 处于各个地方的内网，所有内网都是互通的。其中有一台内网服务器既可以和内网通信，也可以和外网进行通信。

zabbix proxy仅仅需要一条tcp连接到zabbix server,所以zabbix server主机的防火墙上仅仅需要加上一条规则即可。zabbix proxy数据库必须和server分开，否则数据会被破坏，毕竟这两个数据库的表大部分都相同。总之记住，数据库分开即可。

zabbix proxy收集到数据之后，首先将数据缓存在本地，然后在一定得时间之后传递给zabbix server。这个时间由zabbix proxy配置文件中参数ProxyLocalBuffer and ProxyOfflineBuffer决定。

**zabbix proxy 使用场景：**

监控远程区域设备
     监控本地网络不稳定区域
     当 zabbix 监控上千设备时，使用它来减轻 server 的压力
     简化 zabbix 的维护

zabbix proxy 是一个数据收集器,它不计算触发器、不处理事件、不发送报警。

## 二、搭建zabbix-proxy ##

#### 实验 ####

在server3上：  
步骤一：停掉之前配置的zabbix-agent

systemctl stop zabbix-agent.service

步骤二：修改主机名为proxy，方便后续配置

hostnamectl set-hostname proxy

添加本地解析  
![在这里插入图片描述][2020032821521293.png]  
步骤三：安装zabbix-proxy，及数据库mariadb

yum install zabbix-proxy-mysql-4.0.5-1.el7.x86_64.rpm fping-3.10-1.el7.x86_64.rpm -y
    yum install mariadb-server -y

步骤四：开启数据库并配置

systemctl start mariadb.service 
    systemctl enable mariadb.service 
    systemctl status mariadb.service

步骤五：数据库安全初始化

mysql_secure_installation

步骤六：创建数据库zabbix-proxy，并授权

mysql -uroot -predhat
    MariaDB [(none)]> create database zabbix_proxy character set utf8 collate utf8_bin;
    MariaDB [(none)]> grant all privileges on zabbix_proxy.* to zabbix@localhost identified by 'redhat';
    MariaDB [(none)]> show databases;

步骤七：将zabbix-proxy自生成的数据库文件导入数据库

zcat /usr/share/doc/zabbix-proxy-mysql-4.0.5/schema.sql.gz | mysql -uzabbix -p zabbix-proxy    #这里的密码是数据库的登陆密码

在server2上：

vim /etc/zabbix/zabbix_agentd.conf
     98 Server=172.25.1.3
    139 ServerActive=172.25.1.3
    systemctl restart zabbix-agent.service 
    cat /var/log/zabbix/zabbix_agentd.log

![在这里插入图片描述][20200328220311106.png]  
![在这里插入图片描述][20200328220216252.png]![在这里插入图片描述][20200328220220130.png]  
在server3上：

cat /var/log/zabbix/zabbix_proxy.log   #可以在日志中查看到server2的信息

![在这里插入图片描述][20200328220435850.png]

在web界面查看主机：

此时可以查看到server2上的agent服务已经被检测到。  
但是JMX没启用，这是因为我们的代理配置文件的没有设置这个监控，给proxy设置监控java应用的模块。

在server3上：

vim /etc/zabbix/zabbix_proxy.conf 
    329 JavaGateway=172.25.1.1
    337 JavaGatewayPort=10052
    345 StartJavaPollers=5
    systemctl restart zabbix-proxy.service
