Zabbix_Server迁移之Agent地址批量修改

Posted 2020-12-20

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。

(2)脚本执行结果
