 ubantu仓库路径

/etc/sources.list.d/

 安装zabbix_proxy

yum -y install zabbix-proxy-mysql.x86_64 

 安装mysql

mysql> create database zabbix_proxy_active character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on zabbix_proxy_active.* to proxy@localhost identified by "xxxxxxxx";
Query OK, 0 rows affected, 1 warning (0.00 sec)

 导入数据

[root@master-3 mysql]# zcat /usr/share/doc/zabbix-/create.sql.gz | mysql -uproxy -p  zabbix_proxy_active

修改zabbix-proxy配置文件

[root@master-3 mysql]# grep "^[a-Z]"  /etc/zabbix/zabbix_proxy.conf
ProxyMode=0   # 0为主动模式，主动到server获取监控项

修改agent客户端的配置文件，使其指向proxy

[root@master-3 mysql]# grep "^[a-Z]"  /etc/zabbix/zabbix_agent2.conf
PidFile=/var/run/zabbix/zabbix_agent2.pid
LogFile=/var/log/zabbix/zabbix_agent2.log
LogFileSize=512
Server=192.168.64.111,192.168.64.112   # 设置允许的获取本机数据的客户端
ServerActive=192.168.64.112            # 主动模式发送数据给proxy
Hostname=192.168.64.112
Include=/etc/zabbix/zabbix_agent2.d/*.conf
ControlSocket=/tmp/agent.sock

zabbix  server创建agent

 使用agent代理获取数据

 查看proxy日志验证

[root@master-3 mysql]# tail -f /var/log/zabbix/zabbix_proxy.log35725:20220530:014726.571 received configuration data from server at "192.168.64.111", datalen 38608
