zabbix 最后一步无法创建配置文件 zabbix server配置文件

Zabbix的配置文件一般有三种：

• zabbix_server.conf：zabbix server的配置文件
• zabbix_proxy.conf：zabbix proxy的配置文件
• zabbix_agentd.conf：zabbix agentd的配置文件

Zabbix安装完成后，服务端默认的配置文件存在安装文件夹中的etc目录中，假设编译的参数是“--prefix=/usr/local/zabbix”，那么服务端的配置文件则保存在“/usr/loca/zabbix/etc/”目录下。zabbix_server.conf参数除了保证服务正常运行外，还会影响服务器的性能。如果参数设定不合理可能会导致zabbix添加主机不正常、代理端数据无法正常收集或是zabbix服务器性能严重下降，经常报告CPU占用过高或是IO占用过高等问题。本文说明了zabbix server的配置文件中的通用参数和大部分高级参数的具体用法，内容如下：
