Nagios安裝配置1-Linux配置-坐沙發(fā)上等戈多

Nagios安裝配置[1]-Linux 配置 -坐沙發(fā)上等戈多安裝問題 (我找到的中文版之中最好的一個 ,我照著手冊裝了一下，不成功，轉而按照此文，最終成,限于篇幅原因就不在貼上來了,我自己的安裝步驟基本上和這篇相同)/index.php?play=search&make=view&id=282&key=nagios我的安裝步驟(操作系統(tǒng) centoslinxu4.3)1、所需軟件nagios-pluginsimagepak-basenrpeapache2、nagios安裝首先安裝apache 具體過程參考 手冊不在贅述w[]#addusernagios[]#groupaddnagios[]#mkdir/usr/local/nagios[]#./configure--prefix=/usr/local/nagios--with-gd-lib=/usr/local/lib--with-gd-inc=/usr/local/include上面命令用到的 libgd庫，在centos下的安裝可以用以下命令[]#yuminstallgd(gdbphp-gdglib-develgd-devellibpng-devellibpng10-devellibjpeg-develmod_perl-develglibcmod_perl)具體的可參考我上文給出的聯(lián)接[]#makeall[]#makeinstall[]#makeinstall-init ##Thisinstallstheinitscriptin/usr/local/etc/rc.d[]#makeinstall-commandmode[]#makeinstall-config ##將初始的配置文件安裝到/usr/local/nagios/etc2.2、nagios-plugins 的安裝[]#tar–[]#mkdir/usr/local/nagios-plugins[]#./configure--prefix=/usr/local/nagios-plugins[]#makeall[]#makeinstall安裝完成以后在/usr/local/nagios-plugins會產生一個libexec的目錄，將該目錄全部移動到/usr/local/nagios目錄下[]#cp/usr/local/nagios-plugins/libexec/usr/local/nagios/libexec2.3、imagepak-base 的安裝[]#tar–解壓以后是 base目錄[]#cp–Rbase/usr/local/nagios/share/images/logos2.4、安裝過程全部結束4、Nagios的設定:1、配置apache在apache的配置文件httpd.conf中追加(注意，要有image這段，不然 nagios不能顯示圖片，這三段順序好象不能變，不然啟動nagios的時候會提示錯誤 )Alias/nagios/cgi-bin/images/"/usr/local/nagios/share/images/"<Directory"/usr/local/nagios/share/images/">AllowOverrideNoneOptionsNoneOrderallow,denyAllowfromallAuthName"NagiosAccess"AuthTypeBasicAuthUserFile/usr/local/nagios/etc/.htpasswdRequirevalid-user</Directory>ScriptAlias/nagios/cgi-bin/"/usr/local/nagios/sbin/"<Directory"/usr/local/nagios/sbin/">AllowOverrideNoneOptionsNoneOrderallow,denyAllowfromallAuthName"NagiosAccess"AuthTypeBasicAuthUserFile/usr/local/nagios/etc/.htpasswdRequirevalid-user</Directory>Alias/nagios/"/usr/local/nagios/share/"<Directory"/usr/local/nagios/share/">AllowOverrideNoneOptionsNoneOrderallow,denyAllowfromallAuthName"NagiosAccess"AuthTypeBasicAuthUserFile/usr/local/nagios/etc/.htpasswdRequirevalid-user</Directory>2、設置訪問權限在/usr/local/nagios/share目錄下[]#/usr/local/www/bin/htpasswd –c/usr/local/nagios/etc/.htpasswdnagios這個apache目錄根據安裝目錄的不同而不同 ,主要所以用.htpasswd 這個命令生成用戶名和密碼3、配置nagios3.1、在/usr/local/nagios/etc 下是nagios的配置模板文件.cfg-sample,把.cfg-sample文件全部拷貝成.cfg例如:[]#cpnagios.cfg-samplenagios.cfg全部拷貝完成即可 .修改minimal.cfg，把里面所有定義 command 的全部注釋掉[]#vi/etc/minimal.cfg(這個我注釋掉好象有問題 待改正)修改cgi.cfg 改use_authentication=1 為use_authentication=0, 即不用驗證.不然有一些頁面不會顯示。建立所有的 cfg文件[]#touchcontactgroups.cfgcontacts.cfghostgroups.cfghosts.cfgservices.cfgtimeperiods.cfg[]#chownnagios.nagioscontactgroups.cfgcontacts.cfghostgroups.cfghosts.cfgservices.cfgtimeperiods.cfg然后檢查配置文件是否出錯/usr/local/nagios/bin/nagios –v/usr/local/nagios/etc/nagios.cfg出現TotalWarnings:0TotalErrors: 0為正常出錯的話,就是.cfg文件有問題 根據錯誤提示 一個個修正3.5、啟動后臺進程/usr/local/nagios/bin/nagios-d/usr/local/nagios/etc/nagios.cfg/usr/local/etc/rc.d/nagiosstart3.6、(如果有些頁面看不到的話 .可以在cgi.cfg文件中把帶有authorized 的選項前的#號去掉即可)這些配置完以后，基本的 nagios配置完成。5、NRPE的安裝.及監(jiān)按指令的布署nrpe 安裝與使用1、遠程主機的配置1.1、安裝openssl[]#yuminstallopenssl(openssl-devel 等等)1.2、安裝nrpe與配置[]#./configure--enable-ssl--with-ssl-lib=/usr/local/nagios/openssl/lib--with-kerberos-inc=/usr/local/nagios/openssl/include--enable-command-args[]#makeall[]#cpsample-config/nrpe.cfg/usr/local/nagios/etc[]#cpsrc/nrpe/usr/local/nagios/bin[]#vi/usr/local/nagios/etc/nrpe.cfg改成你允許的 IP 是nagios服務器)1.3、啟動nrpe，端口為5666/usr/local/nagios/bin/nrpe-c/etc/nrpe.cfg-d1.4、安裝監(jiān)測的模塊nagios-plugins 的安裝tar–mkdir/usr/local/nagios-pluginscdnagios-plugins-1.4./configure--prefix=/usr/local/nagios-pluginsmakeallmakeinstall安裝完成以后在/usr/local/nagios-plugins會產生一個libexec的目錄，將該目錄全部移動到/usr/local/nagios目錄下mv/usr/local/nagios-plugins/libexec/usr/local/nagios2、服務器上的配置2.1、安裝openssl[]#./config--prefix=/usr/local/nagios/openssl[]#make[]#makeinstall2.2、安裝nrpe(主要是使用 check_nrpe 模塊)[]#./configure--enable-ssl--with-ssl-lib=/usr/local/nagios/openssl/lib--with-kerberos-inc=/usr/local/nagios/openssl/include--enable-command-args[]#makeall[]#cpsrc/check_nrpe/usr/local/nagios/libexec2.3、nagios文件的配置vicheckcommands.cfg定義check_nrpe
