zabbix_proxy离线安装超详细

zabbix_proxy使用

背景

阿里云的网络有俩种网络架构，经典网络和专有网络(vpc)
我们的监控机zabbix是在VPC内网的，如果对经典网络(公网)进行监控呢？
可能方法有很多，但是我使用了zabbix的proxy主动模式，这种场景正符合分布式监控:)

拓扑图

关于proxy的使用场景

zabbix的proxy主动模式proxy 可以用在 Proxy 没有公网 IP ，但可以访问公网的情况下
Zabbix Server <- Zabbix Proxy -> Zabbix Agent
Proxy 去请求 Zabbix Server,由于 Zabbix Agent 用的是被动模式，所以也是由 Zabbix Proxy 去请求 Zabbix Agent
• 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
• 简化分布式监控的维护
zabbix proxy 仅仅需要一条 tcp 连接到 zabbix server
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
官网参考
系统环境：
CentOS Linux release 7.6.1810 (Core)
ip：192.168.21.10 zabbix-proxy地址
192.168.21.11 zabbix-agent地址
192.168.2.15 zabbix-server地址

proxy安装

wget https://repo.zabbix.com/zabbix/5.2/rhel/7/x86_64/zabbix-proxy-mysql-5.2.6-1.el7.x86_64.rpm

1. 下载离线包

2. 安装proxy

[root@localhost tools]# pwd
/home/tools
[root@localhost tools]# ls
zabbix-proxy-mysql-5.2.6-1.el7.x86_64.rpm
[root@localhost ~]# rpm -Uvh zabbix-proxy-mysql-5.2.6-1.el7.x86_64.rpm --nodeps

4. 启动mariadb,默认无密码

[root@localhost tools]# systemctl start mariadb
[root@localhost tools]# systemctl status mariadb

5.proxy需要一个独立的数据库，请勿和server同库。

MariaDB [(none)]> create database zabbix_proxy character set utf8; # 创建数据库
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all on zabbix_proxy.* to zabbix@'%' identified by 'Zabbix@123'; # 创建用户
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant all on zabbix_proxy.* to zabbix@'localhost' identified by 'Zabbix@123'; # 创建用户
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> set password=password('Zabbix@123'); # 设置root密码
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges; # 刷新
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> exit # 退出
Bye

6.导入刷库，无报错代表成功

[root@localhost tools]# zcat /usr/share/doc/zabbix-proxy-mysql-5.2.6/schema.sql.gz | mysql -u zabbix -p'Zabbix@123' zabbix_proxy
[root@localhost tools]#

proxy配置

[root@localhost tools]# vi /etc/zabbix/zabbix_proxy.conf
主要修改以下配置

Server=192.168.2.15 #server的通信IP
ServerPort=10051 #server的端口
Hostname=proxy_fangshan #proxy代理标识
DBPassword=Zabbix@123 #数据库密码
ConfigFrequency=60 #多久从zabbix-server接受配置
DataSenderFrequency=60 #多久向zabbix-server发送收集数据
Timeout=10 　　#等待agent回应超时时间,默认4s

注解（非必要修改）：
ProxyMode=0 //默认主动模式0，被动模式1
DBHost=127.0.0.1 //数据库地址
DBName=zabbix_proxy #数据库名称
DBUser=zabbix #数据库用户
DBPort=3306 #数据库端口
DBSocket=/var/lib/mysql/mysql.sock #数据库sock
LogFileSize=0 //不切割日志,默认1M

[root@localhost tools]# setenforce 0
注：启动失败，没有日志的话参考下面操作
[root@localhost tools]# /usr/sbin/zabbix_proxy #报错没有libodbc.so.2
./zabbix_proxy: error while loading shared libraries: libodbc.so.2: cannot open shared object file: No such file or directory

新建代理

在我们的zabbix界面上点击管理--agent代理程序--创建代理
agent代理程序名称 为 zabbix_proxy的主机名 (建议一致 )

更新完成

添加主机

只需要填写以下
• 主机名称 为 agent的hostname
• 在...群组里
• IP地址 为 agent的内网IP
• 由agent代理程序监测 下拉 选择我们刚创建的代理名称 (敲黑板)
• 模板 添加你需要的模板

再次查看agent代理程序
