Centos7 Zabbix3.4分布式监控zabbix-proxy

我就是我 2023-02-20 08:16 41阅读 0赞

## 官网介绍： ##

zabbix proxy 可以代替 zabbix server 收集性能和可用性数据,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。

此外，当所有agents和proxies报告给一个Zabbix server并且所有数据都集中收集时，使用proxy是实现集中式和分布式监控的最简单方法。

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
 *  简化分布式监控的维护

zabbix proxy 仅仅需要一条 tcp 连接到 zabbix server,所以防火墙上仅仅需要加上一条规则即可。

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，这样就不会因为服务器的任何临时通信问题而丢失数据。这个时间由 [proxy配置文件][proxy]中参数 *ProxyLocalBuffer* 和 *ProxyOfflineBuffer* 决定。

## 实验环境：（同一个局域网） ##

## 一、Zabbix-server部署 ##

1、查看[https://blog.csdn.net/tladagio/article/details/79056421][https_blog.csdn.net_tladagio_article_details_79056421]

## 二、Zabbix-proxy部署 ##

1、测试环境，关闭防火墙和selinux

#修改主机名
    [root@localhost ~]# hostnamectl set-hostname proxy
    #关闭防火墙和selinux
    [root@proxy ~]# systemctl stop firewalld.service
    [root@proxy ~]# systemctl disable firewalld.service
    [root@proxy ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
    [root@proxy ~]# setenforce 0

2、可选，删除系统自带数据库

![20200625185904746.png][]

3、安装zabbix rpm包（注意链接会更新）

[root@proxy ~]# rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm

4、数据库安装和配置

#yum安装
    [root@proxy ~]# yum -y install mariadb mariadb-server
    
    #启动mysql
    [root@proxy ~]# systemctl start mariadb
    [root@proxy ~]# systemctl enable  mariadb
    
    #初始化mysql（修改root用户密码为redhat）
    [root@proxy ~]# mysql_secure_installation
    
    #创建proxy数据库，proxy用户
    [root@proxy ~]# mysql -uroot -p
    MariaDB [(none)]> create database zabbix_proxy character set utf8;
    Query OK, 1 row affected (0.00 sec)
    
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON zabbix_proxy.* to 'zabbix'@'localhost' IDENTIFIED BY 'Proxy123!';
    Query OK, 0 rows affected (0.00 sec)
    
    MariaDB [(none)]> flush privileges;
    Query OK, 0 rows affected (0.00 sec)
    
    MariaDB [(none)]> quit
    Bye

5、安装zabbix-proxy

[root@proxy ~]# yum install -y zabbix-proxy zabbix-proxy-mysql zabbix-agent

6、导入数据库（注意版本号zabbix-proxy-mysql-3.4.15会随着zabbix rpm包改变）

[root@proxy ~]# zcat /usr/share/doc/zabbix-proxy-mysql-3.4.15/schema.sql.gz | mysql -uroot -p zabbix_proxy
    Enter password: 输入密码redhat

7、修改zabbix\_proxy配置文件（注意是Server IP指向zabbix-server的公网映射IP）

[root@proxy ~]# vi /etc/zabbix/zabbix_proxy.conf 
    [root@proxy ~]# cat /etc/zabbix/zabbix_proxy.conf |grep -v "^#"|grep -v "^$"
    Server=113.108.x.x
    Hostname=proxy
    LogFile=/var/log/zabbix/zabbix_proxy.log
    LogFileSize=0
    PidFile=/var/run/zabbix/zabbix_proxy.pid
    SocketDir=/var/run/zabbix
    DBName=zabbix_proxy
    DBUser=zabbix
    DBPassword=Proxy123!
    SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
    Timeout=4
    ExternalScripts=/usr/lib/zabbix/externalscripts
    LogSlowQueries=3000

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 1][]

8、修改zabbix\_agent配置文件（注意Server IP指定zabbix-proxy服务器的IP，这里是同一台机器）

[root@proxy ~]# vi /etc/zabbix/zabbix_agentd.conf 
    [root@proxy ~]# cat /etc/zabbix/zabbix_agentd.conf |grep -v "^#"|grep -v "^$"
    PidFile=/var/run/zabbix/zabbix_agentd.pid
    LogFile=/var/log/zabbix/zabbix_agentd.log
    LogFileSize=0
    Server=192.168.14.211
    ServerActive=192.168.14.211
    Hostname=proxy
    Include=/etc/zabbix/zabbix_agentd.d/*.conf

9、重启服务（如何有新的agent加入，建议重启proxy服务）

[root@proxy ~]# systemctl restart zabbix-agent
    [root@proxy ~]# systemctl restart zabbix-proxy

10、主机名解析

[root@proxy ~]# vi /etc/hosts
    [root@proxy ~]# cat  /etc/hosts
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.14.211	proxy
    192.168.14.212	client-212

11、查看相关日志

[root@proxy ~]# cat /var/log/zabbix/zabbix_proxy.log

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 2][]

## 三、Zabbix-agent部署 ##

1、测试环境，关闭防火墙和selinux

#更改主机名
    [root@localhost ~]# hostnamectl set-hostname client-212
    #关闭防火墙和selinux
    [root@client-212 ~]# systemctl stop firewalld.service
    [root@client-212 ~]# systemctl disable firewalld.service
    [root@client-212 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
    [root@client-212 ~]# setenforce 0

2、安装zabbix rpm包（注意链接会更新）

[root@client-212 ~]# rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm

3、安装zabbix-agent

[root@client-212 ~]# yum install -y zabbix-agent

4、修改zabbix\_agent配置文件（注意Server IP指定zabbix-proxy服务器的IP）

[root@client-212 ~]# vi /etc/zabbix/zabbix_agentd.conf 
    [root@client-212 ~]# cat /etc/zabbix/zabbix_agentd.conf |grep -v "^#"|grep -v "^$"
    PidFile=/var/run/zabbix/zabbix_agentd.pid
    LogFile=/var/log/zabbix/zabbix_agentd.log
    LogFileSize=0
    Server=192.168.14.211
    ServerActive=192.168.14.211
    Hostname=192.168.14.212
    Include=/etc/zabbix/zabbix_agentd.d/*.conf

5、启动服务

[root@client-212 ~]# systemctl start zabbix-agent 
    [root@client-212 ~]# systemctl enable  zabbix-agent

## 四、华为防火墙配置 ##

1、华为防火墙添加zabbix-server的10051端口映射

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 3][]

## 五、Zabbix-server的Web页面设置 ##

1、创建代理

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 4][]

2、填写代理名称并设置模式为主动

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 5][]

3、创建主机

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 6][]

4、填写内容

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 7][]

5、查看状态

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 8][]

6、查看图形能正常收集到数据

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 9][]

至此，zabbix客户端和zabbix服务器在不同的两个公网范围，通过zabbix-proxy代理成功。
