怎么在Linux上安装Icinga

在Linux上安装Icinga

Icinga是一个开源的网络监控工具，它可以监控服务器、网络设备和应用程序的运行状况，它提供了丰富的功能，包括性能监控、日志分析、事件通知等，本文将介绍如何在Linux上安装Icinga。

1、系统要求

在开始安装Icinga之前，请确保您的Linux系统满足以下要求：

操作系统：CentOS 6.x、7.x或8.x，Ubuntu 14.04 LTS或更高版本，Debian 8或更高版本。

内存：至少2GB RAM。

磁盘空间：至少10GB可用空间。

2、添加Icinga仓库

在CentOS和RHEL上，首先需要添加Icinga仓库，执行以下命令：

sudo yum install y epelrelease sudo yum install y wget curl policycoreutilspython opensshserver opensshclients sudo systemctl enable sshd sudo systemctl start sshd sudo firewallcmd permanent addservice=ssh sudo firewallcmd reload

接下来，下载并安装Icinga仓库：

wget https://packages.icinga.org/icinga.repo O /etc/yum.repos.d/icinga.repo

3、安装Icinga Web界面和Icinga Core

现在可以安装Icinga Web界面和Icinga Core了，执行以下命令：

sudo yum install y icinga webinterface icingawebdir libxml2 openssl openssldevel pcre pcredevel zlib zlibdevel gd gddevel freetype freetypedevel libpng libpngdevel jpeg jpegdevel netsnmp netsnmpdevel netsnmputils netsnmputilslibs unixODBC unixODBCdevel unixODBCdevelel postgresql postgresqldevel postgresql93 postgresql93devel python2 python2devel python2pip python2virtualenv python2lxml python2psutil python2pyOpenSSL python2cryptography python2passlib python2ldap python2mysqldb python2sqlite3 python2twisted pyOpenSSL PyNaCl PyYAML PyZMQ PyCrypto PyCryptodome PyMySQL PySMTP PySNMP PyGObject PyGTK PyICU PyQt5 PyQt5.QtSql PyQt5.QtWebSocket PyQt5.QtNetwork Qt5 Qt5.QtXml Qt5.QtGui Qt5.QtWidgets qrencode qrencodedevel rrdtool rrdtoolgraph rrdtoolpng rrdtoolnrtg rrdtool1 rrdtool1graph rrdtool1png rrdtool1nrtg nagios nagiosplugins nagiospluginsextras nagiospluginsstandard nagios3 nagios3core nagios3daemon nagios3nginx nagios3nrpe nagios3plugins nagios3server nagios3webadmin nagioscore nagioscorecgi nagioscorecommon nagioscore3 nagioscore3auth nagioscore3checks nagioscore3eventhandlers nagioscore3filter nagioscore3graphing nagioscore3hostdependency nagioscore3import nagioscore3objectenrichment nagioscore3notificationhandlers nagioscore3outputformatters nagioscore3pluginnagios nagioscore3retention nagioscore3scheduleddowntime nagioscore3servicechecks nagioscore3servicedependency nagioscore3servicegroups nagioscore3servicemonitor nagioscore3servicepoller nagioscore3timeutilities xinetd xinetd.conf xinetd.d xinetd.log xinetd.pid xinetd.services xinetd.state xinetd.useraccess xinetd.version xinetd.logrotate xinetd.conf xinetd.d xinetd.log xinetd.pid xinetd.services xinetd.state xinetd.useraccess xinetd.version xinetd.logrotate

4、配置Icinga Web界面和Icinga Core

安装完成后，需要对Icinga Web界面和Icinga Core进行配置，创建Icinga配置文件：

sudo nano /etc/icinga/icinga.cfg

在icinga.cfg文件中，添加以下内容：

Icinga configuration file for Icinga v2 (master/slave) setup with Nagios v4 and Nagios Plugins v2 (NRPE).
