Nagios安装配置1-Linux配置-坐沙发上等戈多

Nagios安装配置[1]-Linux 配置 -坐沙发上等戈多安装问题 (我找到的中文版之中最好的一个 ,我照着手册装了一下，不成功，转而按照此文，最终成,限于篇幅原因就不在贴上来了,我自己的安装步骤基本上和这篇相同)/index.php?play=search&make=view&id=282&key=nagios我的安装步骤(操作系统 centoslinxu4.3)1、所需软件nagios-pluginsimagepak-basenrpeapache2、nagios安装首先安装apache 具体过程参考 手册不在赘述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库，在centos下的安装可以用以下命令[]#yuminstallgd(gdbphp-gdglib-develgd-devellibpng-devellibpng10-devellibjpeg-develmod_perl-develglibcmod_perl)具体的可参考我上文给出的联接[]#makeall[]#makeinstall[]#makeinstall-init ##Thisinstallstheinitscriptin/usr/local/etc/rc.d[]#makeinstall-commandmode[]#makeinstall-config ##将初始的配置文件安装到/usr/local/nagios/etc2.2、nagios-plugins 的安装[]#tar–[]#mkdir/usr/local/nagios-plugins[]#./configure--prefix=/usr/local/nagios-plugins[]#makeall[]#makeinstall安装完成以后在/usr/local/nagios-plugins会产生一个libexec的目录，将该目录全部移动到/usr/local/nagios目录下[]#cp/usr/local/nagios-plugins/libexec/usr/local/nagios/libexec2.3、imagepak-base 的安装[]#tar–解压以后是 base目录[]#cp–Rbase/usr/local/nagios/share/images/logos2.4、安装过程全部结束4、Nagios的设定:1、配置apache在apache的配置文件httpd.conf中追加(注意，要有image这段，不然 nagios不能显示图片，这三段顺序好象不能变，不然启动nagios的时候会提示错误 )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、设置访问权限在/usr/local/nagios/share目录下[]#/usr/local/www/bin/htpasswd –c/usr/local/nagios/etc/.htpasswdnagios这个apache目录根据安装目录的不同而不同 ,主要所以用.htpasswd 这个命令生成用户名和密码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文件全部拷贝成.cfg例如:[]#cpnagios.cfg-samplenagios.cfg全部拷贝完成即可 .修改minimal.cfg，把里面所有定义 command 的全部注释掉[]#vi/etc/minimal.cfg(这个我注释掉好象有问题 待改正)修改cgi.cfg 改use_authentication=1 为use_authentication=0, 即不用验证.不然有一些页面不会显示。建立所有的 cfg文件[]#touchcontactgroups.cfgcontacts.cfghostgroups.cfghosts.cfgservices.cfgtimeperiods.cfg[]#chownnagios.nagioscontactgroups.cfgcontacts.cfghostgroups.cfghosts.cfgservices.cfgtimeperiods.cfg然后检查配置文件是否出错/usr/local/nagios/bin/nagios –v/usr/local/nagios/etc/nagios.cfg出现TotalWarnings:0TotalErrors: 0为正常出错的话,就是.cfg文件有问题 根据错误提示 一个个修正3.5、启动后台进程/usr/local/nagios/bin/nagios-d/usr/local/nagios/etc/nagios.cfg/usr/local/etc/rc.d/nagiosstart3.6、(如果有些页面看不到的话 .可以在cgi.cfg文件中把带有authorized 的选项前的#号去掉即可)这些配置完以后，基本的 nagios配置完成。5、NRPE的安装.及监按指令的布署nrpe 安装与使用1、远程主机的配置1.1、安装openssl[]#yuminstallopenssl(openssl-devel 等等)1.2、安装nrpe与配置[]#./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改成你允许的 IP 是nagios服务器)1.3、启动nrpe，端口为5666/usr/local/nagios/bin/nrpe-c/etc/nrpe.cfg-d1.4、安装监测的模块nagios-plugins 的安装tar–mkdir/usr/local/nagios-pluginscdnagios-plugins-1.4./configure--prefix=/usr/local/nagios-pluginsmakeallmakeinstall安装完成以后在/usr/local/nagios-plugins会产生一个libexec的目录，将该目录全部移动到/usr/local/nagios目录下mv/usr/local/nagios-plugins/libexec/usr/local/nagios2、服务器上的配置2.1、安装openssl[]#./config--prefix=/usr/local/nagios/openssl[]#make[]#makeinstall2.2、安装nrpe(主要是使用 check_nrpe 模块)[]#./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定义check_nrpe
