zabbix agentd客户端插件Shell一键自动安装脚本
这次生产环境上线了多台Linux服务器，需要全部纳入Zabbix监控范畴，一台一台的去装Zabbix Agentd插件那就太苦逼了，所幸Zabbix客户端插件是支持绿色安装的，就写了个简单的一键安装脚本，然后配合 Secure CRT 的多窗口交互命令一次性就可以搞定了。
正常启动Zabbix客户端服务其实只需要2个文件： zabbix_agentd 和 zabbix_agentd.conf，需要特别说明的是：zabbix_agentd 最好是和 Zabbix_Server 一同编译所得，保证版本和配置文件的路径是一致的，否则可能无法使用Linux系统的 service 服务启动模式。
一、准备工作
Zabbix 主机肯定搭建了WEB服务，所以正好可以将所需放置到WEB目录，方便下载。
客户端插件 zabbix_agentd 位于 Zabbix 安装目录下的 sbin 目录，比如：/usr/local/zabbix/sbin/zabbix_agentd
服务控制脚本 zabbix_agentd 位于 zabbix 源码编译目录下的 misc/init.d/fedora/core/zabbix_agentd
我们要做的就是将这些文件拷贝到 WEB目录即可，比如 /var/www/html/zabbix_agent/ ，根据系统版本的不同，我们可以准备64和32位的 zabbix_agentd，方便后续不同系统下的安装。
拷贝后，手工验证下文件是否可以下载：
客户端插件：http://192.168.1.40/zabbix\_agent/64/zabbix\_agentd
服务控制脚本：http://192.168.1.40/zabbix\_agent/init.d/zabbix\_agentd
二、编写脚本
①、将以下代码保存为 zabbix_agentd.sh ，上传到第一步中的 zabbix_agent 目录。

②、Service 服务控制脚本
为了方便没找到 zabbix agent 服务控制脚本的朋友，额外提供服务控制代码。将代码保存为zabbix_agentd，上传到第一步的 zabbixz_agent/init.d/ 目录备用。

三、使用方法
登录到客户端系统，运行如下命令即可一键安装：
①、使用默认 zabbix_server 的IP地址：
1 | wget http : / / 192.168.1.40 / zabbix_agent / zabbix_agent .sh && chmod + x zabbix_agent .sh && . / zabbix_agent .sh |
②、后面添加IP参数可指定到其他 zabbix_server 或 zabbix_proxy：
1 | wget http : / / 192.168.1.40 / zabbix_agent / zabbix_agent .sh && chmod + x zabbix_agent .sh && . / zabbix_agent .sh 192.168.1.41 |
Secure CRT多会话交互执行：
其他说明：此脚本中的 zabbix_agentd 编译路径（prefix）为 /usr/local/zabbix，如果编译的时候不是这个路径，则需要根据实际情况修改脚本里面相关路径，否则注册的zabbix_agentd服务将无法启动，就只能通过命令行启动了！
