【移动应用开发技术】搭建nagios监控系统

1、软件包准备nagios-4.0.8.tar.gznagios-plugins-2.0.3.tar.gznrpe-2.15.tar.gzhttpd-2.2.23.tar.gz2、NagiosServer端安装1）、安装相关依赖包yuminstall-ygccglibcglibc-commongdgd-develxinetdopenssl-devel2)、安装Nagios#useradd-s/sbin/nologinnagios#configure--prefix=/usr/local/nagios#makeall#makeinstall#makeinstall-init#makeinstall-commandmode#makeinstall-config#chkconfignagioson#chkconfig--list|grepnagios

3)、安装Nagios插件#tarzxvfnagios-plugins-2.0.3.tar.gz#cdnagios-plugins-2.0.3#./configure--prefix=/usr/local/nagios/#make&&makeinstall4）、安装配置apache#tarzxvfhttpd-2.2.23.tar.gz#cdhttpd-2.2.23#./configure--prefix=/usr/local/apache2#make&&makeinstall#vim/usr/local/apache2/conf/http.conf~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Userdaemon

Groupdaemon修改为UsernagiosGroupnagios~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<IfModuledir_module>

DirectoryIndexindex.html

</IfModule>

修改并增加为

<IfModuledir_module>

DirectoryIndexindex.htmlindex.php

</IfModule>AddTypeapplication/x-httpd-php.php

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~增加验证配置，即在httpd.conf文件最后添加如下信息：

#settingfornagios

ScriptAlias/nagios/cgi-bin"/usr/local/nagios/sbin"

<Directory"/usr/local/nagios/sbin">

AuthTypeBasic

OptionsExecCGI

AllowOverrideNone

Orderallow,deny

Allowfromall

AuthName"NagiosAccess"

AuthUserFile/usr/local/nagios/etc/htpasswd

Requirevalid-user

</Directory>

</Directory>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~创建上面的目录验证文件htpasswd#/usr/local/apache2/bin/htpasswd-c/usr/local/nagios/etc/htpasswdnagios#vim/usr/local/nagios/etc/cgi.cfg修改配置文件中所有含有nagiosadmin的内容nagiosadmin=>nagiosadmin,nagios#scp/usr/local/apache2/bin/apachectl/etc/init.d/httpd#vim/etc/init.d/httpd添加以下内容#chkconfig:23458515#description:ApacheisaWorldWideWebServer#chkconfighttpdon#chkconfig--list|grephttpd5）、安装配置php#tarzxvfphp-5.4.10.tar.gz#cdphp-5.4.10#./configure--prefix=/usr/local/php--with-apxs2=/usr/local/apache2/bin/apxs#make&&makeinstall#servicehttpdstart#servicenagiosstart6)、安装nrpe#tarzxvfnrpe-2.15.tar.gz#cdnrpe-2.15#./configure--enable-command-args#makeall#makeinstall-plugin#/usr/local/nagios/libexec/check_nrpe-H03NRPEv2.157)、配置commands.cfg，添加check_nrpe定义vim/usr/local/nagios/etc/objects/commands.cfg#'check_nrpe'commanddefinitiondefinecommand{command_name

check_nrpe

command_line

$USER1$/check_nrpe-H$HOSTADDRESS$-c$ARG1$

}8、配置hosts.cfgvim/usr/local/nagios/etc/objects/hosts.cfgdefinehost{use

linux-serverhost_name

node.3alias

node.3address

03}9、配置node.3.cfg(也就是node.3的services.cfg文件，为了便于管理，每台机器的services.cfg文件分开配置，并以主机名命名)vim/usr/local/nagios/etc/objects/node.3.cfgdefineservice{use

找到NSClientpp服务，双击打开，点击”登录“标签，在”允许服务与桌面交互“前打勾编辑c:\NSClient++-0.2.7\NSC.ini[modules]模块去掉除CheckWMI.dll和RemoteConfiguration.dll以外行的”；“[Settings]去掉password行的注释，并设置密码123456，同时需要在NagiosServer端command.cfg配置文件中check_nt命令定义处配置对应的密码definecommand{command_name
