Zabbix学习(4)-Proxy主动被动部署
Zabbix学习(1)-监控服务与Zabbix介绍
Zabbix学习(2)-Zabbix安装和基础使用
Zabbix学习(3)-Zabbix监控入门
一. Zabbix Proxy 架构
分布式监控文档
Zabbix 通过 Zabbix proxies 为 IT 基础设施提供有效和可用的分布式监控。代理(proxies)可用于代替 Zabbix server 本地收集数据，然后将数据报告给服务器。
zabbix 作为一个分布式监控系统(分布式监控解决方案)，支持通过代理(proxy)收集zabbix agent 的监控数据然后由 zabbix proxy 再把数据发送给 zabbix server，也就是 zabbix proxy 可以代替 zabbix server 收集监控数据，然后把数据汇报给zabbix server，所以 zabbix proxy 可以在一定程度上分担了 zabbix server 的数据收集压力，从而降低了数据的采集时间、也相应的增加了 zabbix server 的监控能力。另外 zabbix proxy 也区分主动模式和被动模式，通信方式与 zabbix server主动模式和被动模式一样，区别是 zabbix proxy 由于没有 zabbix agent 的配置，所以 zabbix proxy 在主动模式下要周期性的向 zabbix server 申请获取 zabbix agent的监控项信息，zabbix proxy 在被动模式下也是等待 zabbix server 的连接并接受 zabbix server 发送的监控项指令，然后再由 zabbix proxy 向 zabbix agent发起请求获取数据。
zabbix proxy MYSQL用于临时存储收集的信息资源数据
二.Zabbix proxy 和 Zabbix server 对比
对比表格:
| 功能\server | zabbxy proxy | zabbix server |
|---|---|---|
| 轻量级 | 是 | 相对重量级 |
| 图形 | 无 | 带图形控制界面 |
| 独立工作 | 是，可以独立采集数据并存储 | 是，即数据采集、存储、分析、展示于一体 |
| 易维护 | 是，配置完成后基本无需管理 | 维护也不难 |
| 独立数据库 | 保留少量最近数据 | 保留指定时间内的所有数据 |
| 报警通知 | 否，代理服务器不发送邮件通知 | 支持邮件、短信等告警机制 |
| 本地管理 | 不支持 | 支持 |
三. Zabbix proxy 部署与使用
zabbix proxy 版本选择
在使用 proxy 做分布式监控时 zabbix proxy 的大版本必须要和 zabbix server版本一致，否则会导致出现 zabbix server 与 zabbix proxy 不兼容问题，出现类似以下的错误提示:
proxy "zabbix-proxy-active" protocol version x.x differs from server version x.x
安装 proxy
官方安装参考手册
ubuntu18.04系统
主机准备：
| 主机类型 | IP地址 |
|---|---|
| zabbix-server | 172.20.32.101 |
| zabbix-proxy-1（主动） | 172.20.32.102 |
| zabbix-proxy-2（被动） | 172.20.32.103 |
| zabbix-Mysql-master | 172.20.32.104 |
| zabbix-Mysql-slave | 172.20.32.105 |
| zabbix-WEB-1 | 172.20.32.106 |
| zabbix-WEB-2 | 172.20.32.107 |
Ubuntu 1804 node1 apt安装
这里有两种方式安装对应的应用，这里在主动模式下用apt安装 在被动模式下用编译安装
root@Zabbix-proxy-active:~# wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-3+bionic_all.deb
root@Zabbix-proxy-active:~# dpkg -i zabbix-release_4.0-3+bionic_all.deb
root@Zabbix-proxy-active:~# apt update
上面的源在国外，可能比较慢，所以可以替换成阿里云的源
阿里开源参考

重启proxy
root@Zabbix-proxy-active:/usr/share/doc/zabbix-proxy-mysql# cd
root@Zabbix-proxy-active:~# systemctl restart zabbix-proxy
root@Zabbix-proxy-active:~# systemctl enable zabbix-proxy
Synchronizing state of zabbix-proxy.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable zabbix-proxy
root@Zabbix-proxy-active:~# tail -f /tmp/zabbix_proxy.log #查看日志看是否报错
web 界面添加主动代理
代理地址可写可不写
主机关联被动模板
这里为了效果明显，复用数据库从库的172.20.32.105的slave数据库服务器添加一个agent代理服务器
在172.20.32.105机器
#从172.20.32.102拷贝deb包到172.20.32.105
root@Zabbix-proxy-active:~# scp zabbix-release_4.0-3+bionic_all.deb 172.20.32.105:/root

#安装
root@Mysql-slave:~# dpkg -i zabbix-release_4.0-3+bionic_all.deb
root@Mysql-slave:~# apt update
root@Mysql-slave:~# apt install zabbix-agent -y
#修改配置文件
root@Mysql-slave:~# vim /etc/zabbix/zabbix_agentd.conf

#重新启动
root@Mysql-slave:~# systemctl restart zabbix-agent
root@Mysql-slave:~# systemctl enable zabbix-agent
Synchronizing state of zabbix-agent.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable zabbix-agent
然后就可以配置主机
命令测试是否主动获取到数据：
root@Zabbix-server:~# /apps/zabbix_server/bin/zabbix_get -s 172.20.32.105 -p10050 -k "system.cpu.load[all,avg1]"
0.000000
稍等一下 然后最终界面：
验证监控数据
扩展
root@Zabbix-server:~# /apps/zabbix_server/bin/zabbix_get -s 172.20.32.104 -p10050 -k "agent.ping"
1
root@Zabbix-server:~# /apps/zabbix_server/bin/zabbix_get -s 172.20.32.105 -p10050 -k "agent.ping"

root@Zabbix-server:~# /apps/zabbix_server/bin/zabbix_get -s 172.20.32.107 -p10050 -k "agent.ping"

实现主动模式java-getewat代理
实现架构
安装java环境
主机duanxin-zabbix-proxy-active: 172.20.32.105-mysql-slave 主动模式下配置java-getewat代理
先要要web主机 172.20.32.105部署Java环境，这里就直接apt安装jdk
root@Mysql-slave:/apps# apt install openjdk-8-jdk -y
#部署tomcat，这里上传到/usr/local/src
# tar xf apache-tomcat-8.5.54.tar.gz
# ln -sv /usr/local/src/apache-tomcat-8.5.54 /apps/tomcat
root@Mysql-slave:/apps# cd /apps/
root@Mysql-slave:/apps# mkdir tomcat/webapps/myapp -p
root@Mysql-slave:/apps# vim tomcat/webapps/myapp/index.html
root@Mysql-slave:/apps# cat tomcat/webapps/myapp/index.html
mysql slave jsp for tomcat test
root@Mysql-slave:/apps# vim tomcat/bin/catalina.sh
