Zabbix_Server迁移之Agent地址批量修改

互联网 diligentman 1个月前 (10-26) 16次浏览

背景需求:
某企业在测试环境上搭建了一套zabbix,并且通过zabbix的自动注册功能已经将几百台机器包括Window和Linux纳入监控,
现需要在生产环境上重新搭建多一套新的zabbix,需要把之前测试环境上添加的所有机器迁移到生产环境上,并且针对Linux操作系统需要在原有指标的基础上补充一些监控指标。

需求分析:
这里有几种方式实现,一是通过一键卸载脚本,结合自动化运维工具,将之前安装的agent批量删除,然后批量安装新的Agent部署包;二是直接修改zabbix_agentd.conf配置文件,将原来的Server地址替换为生产环境上的地址,然后添加进行自定义监控指标的添加,最后重启Agent。本文使用是第二种。

需求实现:
Linux操作系统

(1)制作替换的脚本;操作步骤:一、把对应的新增指标相关脚本放置在对应的脚本目录,这里需要注意zabbix_agent配置文件是否开启Include参数并且指定对应的目录,二是修改zabbix_agentd.conf的配置文件,将Server参数和ActiveServer修改为生产环境的地址,三是重启zabbix_agentd。
