怎样进行Nagios客户端安装

Nagios是一个开源的监控系统，可以用来监控网络服务器、网络设备、应用程序等。Nagios使用一个叫做Nagios客户端的程序来进行监控。下面我们就来介绍一下如何进行Nagios客户端的安装。 首先，下载Nagios客户端的安装包，目前最新的版本是3.5.1。下载地址为： https://www.nagios.org/downloads/nagios-core/ 下载完成后，解压安装包。 tar -xzf nagios-core-3.5.1.tar.gz 进入解压后的目录，执行以下命令来进行安装。 ./configure --with-nagios-user=nagios --with-nagios-group=nagios make all make install make install-init make install-commandmode make install-config make install-webconf 安装完成后，需要执行以下命令来创建Nagios的web管理用户。 htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin 创建完成后，需要重新启动Nagios。 /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 如果一切正常，则会看到以下输出： Nagios Core 3.5.1 Copyright (c) 2009-present Nagios Core Development Team and Community Contributors Copyright (c) 1999-2009 Ethan Galstad Last Modified: 2018-07-26 License: GPL Website: https://www.nagios.org Reading configuration data...

(PID=31559) 如果看到以上输出，则说明Nagios客户端安装成功。 安装完成后，可以通过以下地址来访问Nagios的web界面： http://your_server_ip/nagios 使用刚才创建的用户名和密码来登录。 登录成功后，就可以看到Nagios的监控界面了。
