在Icinga中设置自动恢复功能，可以通过以下步骤进行：
1、安装和配置Icinga
确保已经安装了Icinga，如果没有安装，可以参考官方文档进行安装和配置。
2、启用插件
在Icinga中，需要启用一些插件来实现自动恢复功能，这些插件包括：
Icinga Web 2：用于创建和管理Icinga的Web界面。
Icinga DB：用于存储Icinga的数据。
Icinga LDAP：用于从LDAP目录中获取用户和主机信息。
Icinga NTP：用于同步网络时间。
Icinga PuppetDB：用于从PuppetDB中获取主机信息。
Icinga GeoIP：用于根据IP地址获取地理位置信息。
Icinga Command：用于执行外部命令并检查其输出。
Icinga File Integrity：用于检查文件的完整性。
Icinga Scripts：用于执行自定义脚本。
Icinga Director：用于管理多个Icinga实例。
3、配置主机和服务
在Icinga中，需要为每个主机和服务创建一个配置文件，配置文件通常位于/etc/icinga/conf.d/目录下，对于一台名为webserver的主机，可以创建一个名为webserver.conf的文件，内容如下：
“`
define host {
use linuxserver;
hostname webserver;
address 192.168.1.10;
}
define service {
host_name webserver;
service_description HTTP Server;
check_command http://localhost:80/;
check_interval 5;
normal_check_interval 2;
retry_check_interval 3;
check_period 24×7;
contact_groups admins;
max_check_attempts 3;
check_freshness 5;
event_handlers critical, flapping;
}
“`
4、配置通知模板和联系人组
在Icinga中，可以为不同类型的事件配置通知模板和联系人组，通知模板通常位于/etc/icinga/templates/notifications/目录下，可以创建一个名为httpdown.conf的通知模板，内容如下：
“`
# httpdown.conf template for notifications sent when the HTTP server is down.
# This file is located at /etc/icinga/templates/notifications/httpdown.conf by default.
# To customize the contents of this file, you can create a copy in your own home directory and make changes there.
# For more information about customizing notification templates, see the documentation at: http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/NotificationTemplates.html#customizingnotificationtemplates
define host{ $host_name } {
host_name $host_name; # The name of the host that is down. For example: webserver, dbserver, etc.
use generichost; # Use the generichost template definition for this host notification. See below for available macros and variables that you can use in this template: http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/NotificationTemplates.html#macrosandvariablesavailableinthegenerichosttemplate
