nagios安裝監(jiān)控報(bào)警配置詳解byHF講課講稿

1、Good is good, but better carries it.精益求精，善益求善。nagios安裝監(jiān)控報(bào)警配置詳解byHFNagios安裝與配置詳解內(nèi)容簡(jiǎn)介本文檔介紹nagios監(jiān)控linux服務(wù)器,因?yàn)楸O(jiān)控都是依靠插件去完成的，而監(jiān)控linux主要使用NRPE插件,本文首先簡(jiǎn)單介紹一下NRPE監(jiān)控基礎(chǔ),及監(jiān)控過(guò)程,然后一步步的配置一個(gè)實(shí)例實(shí)現(xiàn)監(jiān)控linux服務(wù)器1.NRPE監(jiān)控插件基礎(chǔ)NRPE總共由兩部分組成:check_nrpe插件,運(yùn)行在監(jiān)控主機(jī)上。NRPEdaemon,運(yùn)行在遠(yuǎn)程的linux主機(jī)上(通常就是被監(jiān)控機(jī))整個(gè)的監(jiān)控過(guò)程:(如下圖)當(dāng)Nagios需要監(jiān)控某個(gè)遠(yuǎn)程li

2、nux主機(jī)的服務(wù)或者資源情況時(shí)：1).nagios運(yùn)行check_nrpe插件,我們要在nagios配置文件中告訴它要檢查什么.2).check_nrpe插件會(huì)通過(guò)SSL連接到遠(yuǎn)程的NRPEdaemon.3).NRPEdaemon會(huì)運(yùn)行相應(yīng)的nagios插件來(lái)執(zhí)行檢查本地資源或服務(wù).4).NRPEdaemon將檢查的結(jié)果返回給check_nrpe插件,插件將其遞交給nagios做處理.注意:NRPEdaemon需要nagios插件安裝在遠(yuǎn)程被監(jiān)控linux主機(jī)上,否則,daemon不能做任何的監(jiān)控.別外因?yàn)樗鼈冮g的通信是加密的SSL,所以在編譯安裝時(shí)都要加上選項(xiàng),./configure-ena

3、ble-ssl-with-ssl-lib=/lib/,否則也會(huì)出錯(cuò).安裝Nagios一、準(zhǔn)備軟件包在做安裝之前確認(rèn)要對(duì)該機(jī)器擁有root權(quán)限。確認(rèn)你安裝好的linux系統(tǒng)上已經(jīng)安裝如下軟件包再繼續(xù)。ApacheGCC編譯器GD庫(kù)與開發(fā)庫(kù)可以用yum命令來(lái)安裝這些軟件包，鍵入命令：yumyinstallhttpdgccglibcglibccommongdgddevelrootlocalhost#rpm-qa|grepgdgd-devel-2.0.33-9.3.fc6gdb-6.5-16.el5gd-2.0.33-9.3.fc6gdbm-1.8.0-26.2.1sysklogd-1.4.1-39.

7、agios2.2創(chuàng)建一個(gè)用戶組名為nagioscmd用于從Web接口執(zhí)行外部命令。將nagios用戶和apache用戶都加到這個(gè)組中。rootlocalhostnagios#groupaddnagioscmdrootlocalhostnagios#usermodGnagioscmdnagiosrootlocalhostnagios#usermodGnagioscmdapache（沒(méi)裝apache可以先不配置）rootlocalhost#less/etc/groupnagios:x:500:nagioscmd:x:501:nagios,apache2.3編譯與安裝Nagiosrootlocalh

10、ourparticularneeds.安裝nagios與別的軟件安裝稍有不同，nagios的安裝要好幾步才能完成。第一步執(zhí)行makeinstall安裝主要的程序、CGI及HTML文件第二步執(zhí)行makeinstall-commandmode給外部命令訪問(wèn)nagios配置文件的權(quán)限第三步執(zhí)行makeinstall-config把配置文件的例子復(fù)制到nagios的安裝目錄第三步執(zhí)行makeinstall-init它的作用是把nagios做成一個(gè)運(yùn)行腳本，使nagios隨系統(tǒng)開機(jī)啟動(dòng)，這是一個(gè)很方便的措施rootlocalhostnagios-3.2.1#ll/usr/local/nagios/tot

14、b功能，因此簡(jiǎn)單的執(zhí)行一下幾個(gè)步驟就可以正確的把a(bǔ)pache安裝到系統(tǒng)：rootlocalhost#tarzxvfhttpd-2.2.0.tar.gzrootlocalhost#cdhttpd-2.2.0rootlocalhost#./configure-prefix=/usr/local/apache-enable-modules=all-enable-sorootlocalhost#make&makeinstall。安裝完成后，執(zhí)行/usr/local/apache/bin/apachectl-t檢查一下apache是否正確安裝。rootlocalhost#/usr/local/apach

15、e/bin/apachectl-tSyntaxOKrootlocalhosthttpd-2.2.15#usermod-Gnagioscmdapache添加到管理組里3.2啟動(dòng)、停止以及重啟服務(wù)器啟動(dòng)服務(wù)器，在安裝目錄的子目錄下，如/usr/local/apache/bin，輸入以下命令即可：rootlocalhosthttpd-2.2.15#./apachectlstart此時(shí)，你服務(wù)器端窗口應(yīng)顯示如下：apachectlstart:httpdstarted此時(shí)，可以在客戶端用瀏覽器輸入服務(wù)器的IP地址，IE應(yīng)該顯示如下畫面：Itworks!停止服務(wù)器，只需在相同的目錄下輸入以下命令：root

16、localhosthttpd-2.2.15#./apachectlstop重新啟動(dòng)服務(wù)器，可輸入以下命令：rootlocalhost#./apachectlgracefulapachectlgraceful:httpdgracefullyrestarted或輸入如下命令：rootlocalhost#./apachectlrestartedapachectlrestart:httpdrestartedrootlocalhost#cp/usr/local/apache/bin/apachectl/etc/rc.d/init.d/httpd這樣就可以實(shí)用servicehttpdStart了3.3配置

17、WEB接口方法一：直接在安裝nagios時(shí)makeinstallwebconf創(chuàng)建一個(gè)nagiosadmin的用戶用于Nagios的WEB接口登錄。記下你所設(shè)置的登錄令，一會(huì)兒你會(huì)用到它。htpasswdc/usr/local/nagios/etc/htpasswd.usersnagiosadmin重啟Apache服務(wù)以使設(shè)置生效。servicehttpdrestart方法二：在httpd.conf最后添加如下內(nèi)容：#settingfornagios20090325#ScriptAlias/nagios/cgi-bin/usr/local/nagios/sbinOptionsExecCGIAl

37、nagios.cfg重啟動(dòng)Nagios當(dāng)你修改了配置文件并想使之生效的話，重啟動(dòng)或重載入動(dòng)作是必須的。初始化腳本：最簡(jiǎn)單地重啟動(dòng)Nagios守護(hù)進(jìn)程的方式是使用初始化腳本，象這樣：/etc/rc.d/init.d/nagiosreload評(píng)估啟動(dòng)時(shí)間/usr/local/nagios/bin/nagioss/usr/local/nagios/etc/nagios.cfg六、通過(guò)WEB管理nagios也可以通過(guò)nagios的web頁(yè)面重啟服務(wù)和添加監(jiān)控，設(shè)置如下：1、apache的運(yùn)行用戶添加到nagioscmd組里2、nagios.cfg里command_file=/usr/local/nag

44、我改為如下這樣allowed_hosts=/32,11以逗號(hào)相隔.這個(gè)地方是支持子網(wǎng)的,如果寫成/24則表示該子網(wǎng)內(nèi)的所有機(jī)器都可以訪問(wèn).如果這個(gè)地方是空白則表示所有的主機(jī)都可以連接上來(lái).注意是Settings部分的,因?yàn)镹SClient部分也有這個(gè)選項(xiàng).必須保證NSClient的port選項(xiàng)并沒(méi)有被注釋,并且它的值是12489,這是NSClient的默認(rèn)監(jiān)聽(tīng)端口5進(jìn)入CMD命令行，啟動(dòng)NSClient+nsclient+.exe-start6netstat-an如果看到以下信息說(shuō)明成功TCP:1248:0LISTENING然后查看服務(wù)是否自動(dòng)啟動(dòng)已經(jīng)正常啟動(dòng)了.注意服務(wù)默認(rèn)設(shè)的是”自動(dòng)”,也

45、就是說(shuō)是開機(jī)自動(dòng)啟動(dòng)的.2、對(duì)監(jiān)控主機(jī)的配置接下來(lái)就是要配置監(jiān)控主機(jī)了.與之前的nrpe的過(guò)程類似,在監(jiān)控主機(jī)上做的就3件事情1.安裝監(jiān)控windows的插件(已經(jīng)默認(rèn)安裝了,check_nt)2.定義命令3.定義要監(jiān)控的項(xiàng)目定義命令vi/usr/local/nagios/etc/commands.cfg增加下面的內(nèi)容#2007.9.6addbyyahoon#CHECK_NT#checkwindowshostsinfo#definecommandcommand_namecheck_nt_effemcommand_line$USER1$/check_nt-H$HOSTADDRESS$-p1248
