【移動(dòng)應(yīng)用開發(fā)技術(shù)】Nagios4.0.1版本安裝適用于RHELCentos5.x6.x或者Fedora171819(一)

我的環(huán)境如下：Centos-6.2Nagios4.0.1NagiosPlugin1.5Nagios是一個(gè)非常棒的免費(fèi)的開源的監(jiān)控工具，它提供給你一個(gè)很全面的監(jiān)控環(huán)境，始終密切監(jiān)視你的機(jī)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(gè)小實(shí)驗(yàn)室。步驟1：安裝需要的依賴包

需要安裝Apache、PHP和一些庫(kù)像：gcc、glibc、glibc-common、gd、gd-devel、make、net-snmp[root@taoteng~]#yuminstall-yhttpdphpgccglibcglibc-commongdgd-develmakenet-snmp創(chuàng)建一個(gè)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(lái)，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(gè)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(lái)下載最新版本的Nagio-4.0.1和Nagios-plugin-1.5通過(guò)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(guò)tar命令來(lái)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(huì)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(yùn)行configure命令，如果一切運(yùn)行順利將會(huì)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:

}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(lái)將用下面的命令來(lái)配置Nagios的web接口。下面的命令將配置web接口并同時(shí)創(chuàng)建一個(gè)“nagiosadmin”管理用戶。[root@taotengnagios-4.0.1]#makeinstall-webconf接下來(lái)的這步將會(huì)創(chuàng)建一個(gè)密碼為“nagiosadmin”記住這個(gè)密碼，因?yàn)榇龝?huì)兒在瀏覽器中登錄的時(shí)候?qū)?huì)用到這個(gè)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(yàn)證nagios配置文件的是否有錯(cuò)誤（這就是nagios其中的一個(gè)很不錯(cuò)的地方，可以很清晰的告訴你是否有錯(cuò)誤）如果沒(méi)有什么錯(cuò)誤就輸出下面的語(yǔ)句：[root@taotengnagios]#/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfgs輸出示例：Runningpre-flightcheckonconfigurationdata...Checkingservices...
