我的環(huán)境如下：Centos-6.2Nagios4.0.1NagiosPlugin1.5Nagios是一個非常棒的免費的開源的監(jiān)控工具，它提供給你一個很全面的監(jiān)控環(huán)境，始終密切監(jiān)視你的機器或者網(wǎng)絡(luò)，不管是在數(shù)據(jù)中心還是在你自己的一個小實驗室。步驟1：安裝需要的依賴包

需要安裝Apache、PHP和一些庫像：gcc、glibc、glibc-common、gd、gd-devel、make、net-snmp[root@taoteng~]#yuminstall-yhttpdphpgccglibcglibc-commongdgd-develmakenet-snmp創(chuàng)建一個新的nagios用戶和nagcmd組賬戶并設(shè)置密碼。[root@taoteng~]#useraddnagios

[root@taoteng~]#groupaddnagcmd接下來，添加nagios和Apache用戶到nagcmd組。[root@tecmint]#usermod-Gnagcmdnagios[root@tecmint]#usermod-Gnagcmdapache步驟3：下載Nagios-4.0.1和Nagios-plugin-1.5

在/root目錄下創(chuàng)建一個安裝包以及后續(xù)需要下載的安裝包的目錄。[root@taoteng~]#mkdir/root/nagios

[root@taoteng~]#cd/root/nagios

現(xiàn)在來下載最新版本的Nagio-4.0.1和Nagios-plugin-1.5通過wget命令

[root@taotengnagios]#wget/sourceforge/nagios/nagios-4.0.1.tar.gz

[root@taotengnagios]#wget/download/nagios-plugins-1.5.tar.gz步驟4：提取Nagios和nagios-plugins壓縮包

我們需要通過tar命令來提取下載的壓縮包里面的文件：

[root@taotengnagios]#tar-zxvfnagios-4.0.1.tar.gz

[root@taotengnagios]#tar-zxvfnagios-plugins-1.5.tar.gz緊接著nagios文件夾里面將會出現(xiàn)解壓之后的文件夾[root@taotengnagios]#ll總用量30668drwxrwxr-x18root

2月2020:58nagios-plugins-1.5.tar.gz配置nagios的核心現(xiàn)在，首先我們將配置nagios核心，將進(jìn)入到nagios文件夾里面運行configure命令，如果一切運行順利將會出現(xiàn)下面的界面：[root@taotengnagios]#cdnagios-4.0.1[root@taotengnagios-4.0.1]#./configure--with-command-group=nagcmd輸出示例：Nagiosexecutable:

Iftheylookokay,type'makeall'tocompilethemainprogramandCGIs.隨后配置和編譯所有的的二進(jìn)制文件，make和makeinstall將會在你的機器上安裝所需的二進(jìn)制文件然后才能繼續(xù)安裝，[root@taotengnagios-4.0.1]#make[root@taotengnagios-4.0.1]#makeinstall輸出樣例：***Mainprogram,CGIsandHTMLfilesinstalled***YoucancontinuewithinstallingNagiosasfollows(type'make'withoutanyargumentsforalistofallpossibleoptions):

makeinstall-config

-Thisinstallssampleconfigfilesin/usr/local/nagios/etc其實從上面的樣例上可以看出下步我們需要的操作步驟，接著執(zhí)行makeinstall-init去安裝初始化腳本。[root@taotengnagios-4.0.1]#makeinstall-init從輸出的命令行上可以看出我們需要安裝外部命令文件(libxce)[root@taotengnagios-4.0.1]#makeinstall-commandmode接下來安裝nagios示例文件，運行下面的命令：[root@taotengnagios-4.0.1]#makeinstall-config輸出示例：/usr/bin/install-c-m775-onagios-gnagios-d/usr/local/nagios/etc/usr/bin/install-c-m775-onagios-gnagios-d/usr/local/nagios/etc/objects/usr/bin/install-c-b-m664-onagios-gnagiossample-config/nagios.cfg/usr/local/nagios/etc/nagios.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/cgi.cfg/usr/local/nagios/etc/cgi.cfg/usr/bin/install-c-b-m660-onagios-gnagiossample-config/resource.cfg/usr/local/nagios/etc/resource.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/templates.cfg/usr/local/nagios/etc/objects/templates.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/commands.cfg/usr/local/nagios/etc/objects/commands.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/contacts.cfg/usr/local/nagios/etc/objects/contacts.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/timeperiods.cfg/usr/local/nagios/etc/objects/timeperiods.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/localhost.cfg/usr/local/nagios/etc/objects/localhost.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/windows.cfg/usr/local/nagios/etc/objects/windows.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/printer.cfg/usr/local/nagios/etc/objects/printer.cfg/usr/bin/install-c-b-m664-onagios-gnagiossample-config/template-object/switch.cfg/usr/local/nagios/etc/objects/switch.cfg***Configfilesinstalled***Remember,theseare*SAMPLE*configfiles.

}步驟6：安裝和配置Nagios的web接口到目前為止，我們已經(jīng)完成了所有的配置，接下來將用下面的命令來配置Nagios的web接口。下面的命令將配置web接口并同時創(chuàng)建一個“nagiosadmin”管理用戶。[root@taotengnagios-4.0.1]#makeinstall-webconf接下來的這步將會創(chuàng)建一個密碼為“nagiosadmin”記住這個密碼，因為待會兒在瀏覽器中登錄的時候?qū)玫竭@個密碼。[root@taotengnagios-4.0.1]#htpasswd-s-c/usr/local/nagios/etc/htpasswd.usersnagiosadmin

Addingpasswordforusernagiosadmin重啟Apache服務(wù)使新的配置生效。[root@taotengnagios-4.0.1]#servicehttpdrestart(OnRedHat/CentOS)[root@taotengnagios-4.0.1]#systemctlstarthttpd.service(OnFedora)步驟7：編譯和安裝nagios插件。這兒已經(jīng)下載了nagios插件在/root/nagios目錄下面，直接進(jìn)去編譯和安裝即可：[root@taotengnagios]#tar-zxvfnagios-plugins-1.5[root@taotengnagios]#./configure--with-nagios-user=nagios--with-nagios-group=nagios[root@taotengnagios]#make[root@taotengnagios]#makeinstall步驟8：驗證nagios配置文件的是否有錯誤（這就是nagios其中的一個很不錯的地方，可以很清晰的告訴你是否有錯誤）如果沒有什么錯誤就輸出下面的語句：[root@taotengnagios]#/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfgs輸出示例：Runningpre-flightcheckonconfigurationdata...Checkingservices...
