4 Frontend maintenance mode前端维护模式
Overview概述
Zabbix web frontend can be temporarily disabled in order to prohibit access to it. This can be useful for protecting the Zabbix database from any changes initiated by users, thus protecting the integrity of database. Zabbix web前端可以暂时禁用，以禁止访问它。 这对于保护Zabbix数据库免受用户发起的任何更改非常有用，从而保护了数据库的完整性。
Zabbix database can be stopped and maintenance tasks can be performed while Zabbix frontend is in maintenance mode. Zabbix数据库可以被停止，并且维护任务可以在Zabbix 前端在维护模式中进行。
Users from defined IP addresses will be able to work with the frontend normally during maintenance mode. 来自指定IP地址的用户将能够在维护模式期间正常工作。
Configuration配置
In order to enable maintenance mode, the maintenance.inc.php file (located in /conf of the Zabbix HTML document directory on the webserver) must be modified to uncomment the following lines: 为了启用维护模式，必须以取消注释的方法修改 maintenance.inc.php文件（位于web服务器上的Zabbix HTML 文档目录的/ conf中）：
// Maintenance mode. 维护模式
define('ZBX_DENY_GUI_ACCESS', 1);
// Array of IP addresses, which are allowed to connect to frontend (optional). 一列包含IP地址的数组，它们可以连接到前端（可选）
$ZBX_GUI_ACCESS_IP_RANGE = array('127.0.0.1');
// Message shown on warning screen (optional). 警告屏幕上所显示的信息（可选）
$ZBX_GUI_ACCESS_MESSAGE = 'We are upgrading MySQL database till 15:00. Stay tuned...';| Parameter参数 D | tails详情 |
