其实Icinga是Nagios监控的一个分支，有两个分支版本Icinga1和Icinga2；Icinga除了完全兼容Nagios的插件和扩展甚至配置文件，在web接口和报告上有很大的改进，并且简化了插件的开发；Icinga1和Nagios的基础监控类似，增加了一些新的特性和修复了Nagios的一些bug

下面基于Centos7来安装Icinga1：


一、安装LAMP环境
1.安装apache和php 
yum -y install httpd php php-pear php-xmlrpc php-xsl php-soap php-mysql php-pdo php-gd php-mbstring
防火墙放行httpd服务
firewall-cmd —add-service=http (临时放行)
firewall-cmd —permanent —add-service=http（永久放行，写入配置文件，系统重启后依然有效）
systemctl start http.service

vim /var/www/html/info.php



测试php解析是否正常
vim /etc/php.ini
date.timezone= PRC

2.安装Mariadb

yum -y install mariadb-server mariadb
mysql_secure_installation
systemctl start mariadb
systemctl status mariadb

二、安装icinga监控工具

wget http://packages.icinga.org/epel/ICINGA-release.repo -O /etc/yum.repod/icinga.repo
rpm --import http://packages.icinga.org/icinga.key
yum  -y install icinga icinga-doc icinga-gui
htpasswd -cm /etc/icinga/passwd  geekwolf
systemctl start icinga
systemctl start httpd

三、安装Nagios插件

   rpm -Uvh http://ftp.ines.lug.ro/fedora/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm
   yum -y install nagios-plugins nagios-plugins-all
   配置文件路径/etc/icinga，配置方式和nagios一样


   vim  /etc/icinga/cgi.cfg
   authorized_for_system_information=geekwolf
   authorized_for_configuration_information=geekwolf
   authorized_for_full_command_resolution=geekwolf
   authorized_for_system_commands=geekwolf
   authorized_for_all_services=geekwolf
   authorized_for_all_hosts=geekwolf
   authorized_for_all_service_commands=geekwolf
   authorized_for_all_host_commands=geekwolf
