【移動應(yīng)用開發(fā)技術(shù)】nagios詳細的安裝及配置！

一、安裝前的準備1.下載到核心源碼：wget/projects/nagios/files/nagios-3.x/nagios-3.4.3/nagios-3.4.3.tar.gz/download2.下載插件包：[root@gjp~]#wget/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.tar.gz3.nagios服務(wù)器端軟件和客戶端軟件[root@gjp~]#wget/project/nagios/nrpe-2.x/nrpe-2.13/nrpe-2.13.tar.gz4.源碼安裝前需要先確定已經(jīng)安裝apache，gcc，GD庫和開發(fā)庫我本地DVD上沒有g(shù)d-devel,所以我又加一一個163的鏡像源yuminstall-yhttpdphpgccglibcglibc-commongdgd-develperlmake二、監(jiān)控端：第1個步驟：創(chuàng)建一個名為nagios的帳號并給定登錄口令/usr/sbin/useraddnagiospasswdnagios#密碼123456創(chuàng)建一個用戶組名為nagcmd用于從Web接口執(zhí)行外部命令。將nagios用戶和apache用戶都加到這個組中。/usr/sbin/groupaddnagcmd/usr/sbin/usermod-Gnagcmdnagios/usr/sbin/usermod-Gnagcmdapache[root@gjpnagios]#yuminstallsendmail–ycd/rootnagios下載目錄tarxzfnagios-3.4.3.tar.gzcdnagios運行Nagios配置腳本并使用先前開設(shè)的用戶及用戶組：./configure--with-command-group=nagcmd下面這個，我這里沒指定makeallmakeinstallmakeinstall-initmakeinstall-configmakeinstall-commandmode把Nagios加入到服務(wù)列表中以使之在系統(tǒng)啟動時自動啟動現(xiàn)在還不能啟動Nagios－還有一些要做的...客戶后配置樣例配置文件默認安裝在這個目錄下/usr/local/nagios/etc，這些樣例文件可以配置Nagios使之正常運行，只需要做一個簡單的修改...用你擅長的編輯器軟件來編輯這個/usr/local/nagios/etc/objects/contacts.cfg配置文件，更改email地址nagiosadmin的聯(lián)系人定義信息中的EMail信息為你的EMail信息以接收報警內(nèi)容。vi/usr/local/nagios/etc/objects/contacts.cfg配置WEB接口安裝Nagios的WEB配置文件到Apache的conf.d目錄下nagios-3.4.3.tar.gz解壓后的nagios中執(zhí)行[root@gjp~]#cdnagios[root@gjpnagios]#makeinstall-webconf在ls/etc/httpd/conf.d/下，會出現(xiàn)nagios.conf文件第2個步驟：ngios插件下面使用的版本與上面不同：展開Nagios插件的源程序包cd/roottarxzfnagios-plugins-1.4.16.tar.gzcdnagios-plugins-1.4.16yuminstall-yopensslopenssl-devel編譯并安裝插件./configure--with-nagios-user=nagios--with-nagios-group=nagiosmake&&makeinstall第3個步驟：安裝nagios漢化插件（此步，我跳過了）第4個步驟：我在這里采用的yum安裝！以上，是參考文檔，我這里如下配置：因為前面建立了個用戶組，把nagios和apache都添加進去了！因此，我這里無需改動：除了這個無需改動，其他修改如上創(chuàng)建一個nagiosadmin的用戶用于Nagios的WEB接口登錄。記下你所設(shè)置的登錄口令，一會兒你會用到它。htpasswd-c/usr/local/nagios/etc/htpasswdnagiosadmin#密碼123456重啟Apache服務(wù)以使設(shè)置生效。servicehttpdrestart如果出現(xiàn)服務(wù)啟動不了,出現(xiàn)這樣啟動Nagios驗證Nagios的樣例配置文件/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg如果沒有報錯，可以啟動Nagios服務(wù)servicenagiosstart[root@gjpnagios-plugins-1.4.16]#servicenagiosstartStartingnagios:done.界面：04:1080/nagios/訪問時，輸入用戶名和密碼：則是vim/usr/local/nagios/etc/htpasswd該文件中的用戶和密碼！三、中間出現(xiàn)的問題及解決方法：這時,監(jiān)控端已配置好：04:1080/nagios/訪問時,卻發(fā)現(xiàn),訪問不到Apache重啟才能生效!如果無法訪問，查看apache服務(wù)是否開啟，如果啟動不了，查原因，我這里是由于selinux沒關(guān)閉，導(dǎo)致的，vim/etc/selinux/config把#SELINUX=enforcingSELINUX=disabled如果apache正常，扔無法打開web，則查看iptables如iptables–F規(guī)則，清理下，ok四、NEPR監(jiān)控遠程主機在監(jiān)控機上安裝cd/roottarxvfnrpe-2.13.tar.gzcdnrpe-2.13./configuremakeall&&makeinstall-plugin在文件/usr/local/nagios/etc/objects/commands.cfg后面增加：#'check_nrpe'commanddefinitiondefinecommand{command_namecheck_nrpecommand_line$USER1$/check_nrpe-H$HOSTADDRESS$-t30-c$ARG1$}定義主機：vim/usr/local/nagios/etc/nagios.cfg/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg監(jiān)測看到如下:這里有1個警告，是沒問題的！/etc/init.d/nagiosrestart看到界面如下：定義相應(yīng)的服務(wù):vim/usr/local/nagios/etc/objects/service.cfg(自己創(chuàng)建的)[root@rootobjects]#catservice.cfgdefineservice{usegeneric-service;host_nametest;service_descriptionusers;check_commandcheck_nrpe!check_users;}defineservice{usegeneric-service;host_nametest;service_descriptionload;check_commandcheck_nrpe!check_load;}defineservice{usegeneric-service;host_nametest;service_descriptiondisk;check_commandcheck_nrpe!check_disk;}defineservice{usegeneric-service;host_nametest;service_descriptionzombie;check_commandcheck_nrpe!check_zombie_procs;}defineservicegroup{servicegroup_nameservergroup;aliasserver-group;memberstest,users,test,load,test,disk,test,zombie;}(這個文檔對應(yīng)的是被監(jiān)控端的vim/usr/local/nagios/etc/nrpe.cfg中定義的命令，如command[check_users]=/usr/local/nagios/libexec/check_users-w10-c16)寫完后，進行驗證：/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg然后記著重啟nagios出現(xiàn)上面：在被監(jiān)控端06：在監(jiān)控端：[root@rootobjects]#/usr/local/nagios/libexec/check_nrpe-H06-ccheck_diskDISKOK-freespace:/6666MB(72%inode=95%);|/=2521MB;9188;9488;0;9688上面的HTTP錯誤，開放80端口，在httpd.conf中，增加Listen80，然后，apache服務(wù)重啟，解決！在被監(jiān)控機上：在這里,我的操作如下：groupaddnagiosuseradd-gnagios-d/usr/local/nagios-s/sbin/nologinnagioscd/tmp/tarxvfnagios-plugins-1.4.16.tar.gzcdnagios-plugins-1.4.16./configure--with-nagios-user=nagios--with-nagios-group=nagios--enable-redhat-pthread-workaroundmake&&makeinstallcd/roottarxvfznrpe-2.13.tar.gzcdnrpe-2.13./configuremakeallmakeinstall-pluginmakeinstall-daemonmakeinstall-daemon-config具體操作如下：更改/usr/local/nagios/etc/nrpe.cfg文件，在參數(shù)allowed_hosts后添加監(jiān)控機ip（多個ip以逗號分隔，目前監(jiān)控及ip為36,11）可以在/etc/services結(jié)尾增加：echo'nrpe5666/tcp#NRPE'>>/etc/services/usr/local/nagios/libexec/check_nrpe-HlocalhostNRPEv2.13更改/usr/local/nagios/etc/nrpe.cfg，把原來command都注釋掉nrpe.cfg文件里包含需要監(jiān)控遠程主機的命令，如：echo'command[check_users]=/usr/local/nagios/libexec/check_users-w10-c16command[check_load]=/usr/local/nagios/libexec/check_load-w15,10,5-c30,25,20command[check_disk]=/usr/local/nagios/libexec/check_disk-w500-c200-p/command[check_zombie_procs
