此平台是基于apache2.2.1+php5.3.0+nagios3.1.2+fetion2009等软件的组合搭建而出，这些软件的版本是现阶段 最新的。本人经过一段时间的搭建与测试，各个功能都能够成功实现，现源于开源软件，本人却不敢独享，现把搭建与配置过程介绍如下：
一、服务器端的设置
1、下载需求软件：
nagios主程序：
nagios插件程序：
apache程序：
php程序：
libACE程序：
fetion机器人程序：
2、软件的安装
(1) apache的安装
[root@localhost httpd-2.2.11]# ./configure –prefix=/usr/local/apache –enable-so
[root@localhost httpd-2.2.11]# make && make install容
[root@localhost httpd-2.2.11]# make && make install容
(2) php的安装
[root@localhost php-5.2.10]# ./configure –prefix=/usr/local/php
> –with-apxs2=/usr/local/apache/bin/apxs
[root@localhost php-5.2.10]# make && make install
[root@localhost php-5.2.10]# cp php.ini-dist /usr/local/lib/php.ini
[root@localhost php-5.2.10]# vi /usr/local/apache/conf/httpd.conf请
> –with-apxs2=/usr/local/apache/bin/apxs
[root@localhost php-5.2.10]# make && make install
[root@localhost php-5.2.10]# cp php.ini-dist /usr/local/lib/php.ini
[root@localhost php-5.2.10]# vi /usr/local/apache/conf/httpd.conf请
为了配置文件的工整，在配置文件的相关地方加入如下配置：
LoadModule php5_module modules/libphp5.so（如果有，不用加）
AddType application/x-httpd-php .php .html
找到DirectoryIndex index.html
改为：DirectoryIndex index.php index.html
在最后加入nagios的访问目录：
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory “/usr/local/nagios/sbin”>
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory “/usr/local/nagios/share”>
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
</Directory> 请输入内容
AddType application/x-httpd-php .php .html
找到DirectoryIndex index.html
改为：DirectoryIndex index.php index.html
在最后加入nagios的访问目录：
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory “/usr/local/nagios/sbin”>
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory “/usr/local/nagios/share”>
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
</Directory> 请输入内容
(3) nagios的安装
为了支持Nagios安装完后status map,trend等完全显示，需要gd库的支持，首先看一下gd与gd-devel有没有安装
[root@localhost php-5.2.10]# rpm -qa|grep gdgdb-6.5-37.el5libgdiplus-1.2.5-1.el5.centosgd-2.0.33-9.4.el5_1.1gdbm-1.8.0-26.2.1sysklogd-1.4.1-44.el5libgdiplus-devel-1.2.5-1.el5.centosgd-devel-2.0.33-9.4.el5_1.1如果没有，请拿出光盘安装上，或者用yum -y install gd*安装也可
[root@localhost nagios-3.1.2]# useradd nagios [root@localhost nagios-3.1.2]# ./configure –prefix=/usr/local/nagios> –with-gd-lib=/usr/lib –with-gd-inc=/usr/include –with-nagios-user=nagios> –with-nagios-group=nagios[root@localhost nagios-3.1.2]# make all [root@localhost nagios-3.1.2]# make install [root@localhost nagios-3.1.2]# make install-init[root@localhost nagios-3.1.2]# make install-commandmode[root@localhost nagios-3.1.2]# make install-config(4) nagios-plugin的安装
[root@localhost nagios-plugins-1.4.13]# ./configure –prefix=/usr/local/nagios[root@localhost nagios-plugins-1.4.13]# make && make install(5) 飞信机器人的安装
在安装飞信之前需要在/usr/lib目录下加上libACE库文件，以便使飞信能够正常使用
[root@localhost src]# tar zxvf library_linux.tar.gz[root@localhost src]# mv libACE* libcrypto.so.0.9.8 libssl.so.0.9.8 /usr/lib好了，现在来正式安装飞信
[root@localhost src]# tar zxvf fetion20090406003-linux.tar.gz [root@localhost src]# mv install /usr/local/fetion [root@localhost src]# chmod -R 755 /usr/local/fetion [root@localhost src]# chown -R nagios:nagios /usr/local/fetion测试飞信能否成功发送短信（发送对象需是自己飞信好友）：
[root@localhost src]# /usr/local/fetion/fetion –mobile=137*** –pwd=***> –to=136*** –msg-utf8=”test”如果136***能成功收到137***的短信就是正常的哟，如果不能成功看日志。
3、nagios的配置
首先讲一下，我建有host(主机），hostgroup(主机组），contact（联系人），contactgroup(联系人组），分别讲一下它们的相关情况：
host包含：TH-02,VH-178,VH-132,MH-110,MH-13
hostgroup包含：TG(别名：testgroup) , VG(别名：virtualgroup),MG(别名：maintaingroup)；TG包括主机：TH-02，VG包括主机：VH-132，VH-178，MG包括主机：MH-110,MH-13
contact包含：WSP,HW,ZY
contactgroup包含：testers,virtualers,maintainers；testers包含用户：WSP，virtualers包含用户：WSP和HW,maintainers包含用户：ZY
为了直观起见，请看下图，
好了，有了大致模块以后，现在我们正式开始配置nagios吧
(1) host的编辑与添加
为了灵活使用，我们直接进入/usr/local/nagios/etc/objects目录下面，
[root@localhost src]# cd /usr/local/nagios/etc/objects/[root@localhost objects]# touch hosts.cfg##########################################################################

(2) contacts.cfg的编辑
################################################################################ CONTACTS.CFG – SAMPLE CONTACT/CONTACTGROUP DEFINITIONS## Last Modified: 05-31-2007## NOTES: This config file provides you with some example contact and contact# group definitions that you can reference in host and service# definitions.## You don’t need to keep these definitions in a separate file from your# other object definitions.

为了支持飞信发短信的功能需要在此文件中添加飞信命令，以促使信息的发送，代码如下：
# ‘notify-host-by-fei’ command definition
define command { command_name host-notify-by-fei ; command_line /usr/local/fetion/fetion –mobile=137*** –pwd=*** –to=$CONTACTPAGER$ –msg-utf8=”Host $HOSTSTATE$ alert for $HOSTNAME$! on ‘$LONGDATETIME$’” $CONTACTPAGER$ } # ‘notify-service-by-fei’ command definition define command { command_name service-notify-by-fei command_line /usr/local/fetion/fetion –mobile=137*** –pwd=*** –to=$CONTACTPAGER$ –msg-utf8=”$HOSTADDRESS$ $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ on $LONGDATETIME$” $CONTACTPAGER$ }(4) 编辑nagios.cfg
为了不监控本机，现把localhost注释掉，找到此行，并且加以注释：# cfg_file=/usr/local/nagios/etc/objects/localhost.cfg为了使刚才编辑的文件生效，需加入一行：cfg_file=/usr/local/nagios/etc/objects/hosts.cfg(5) 编辑cgi.cfg
为了保证权限能正常访问nagios的web页面，需把这些行的值改掉：
authorized_for_system_information=*authorized_for_configuration_information=*authorized_for_system_commands=nagiosauthorized_for_all_services=*authorized_for_all_hosts=*authorized_for_all_service_commands=*authorized_for_all_host_commands=**号在此表示所有用户，也可以改成相关用户，不过必须逐一添加。服务器端的配置基本上大致如此了。
4、启动nagios与apache服务
(1) nagios自启动
[root@localhost objects]# service nagios restartRunning configuration check…done.Stopping nagios: done.Starting nagios: done.[root@localhost objects]# chkconfig nagios on [root@localhost objects]# chkconfig –list|grep nagiosnagios 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭(2) apache的启动
[root@localhost ~]# export PATH=$PATH:/usr/local/apache/bin[root@localhost ~]# apachectl -k starthttpd (pid 3108) already running注：为了让apache可以自启动，可以加入到/etc/rc.local之中。
5、测试与浏览
在启动nagios服务之前，我们可以先测试一下是否配置有没有错误，或者你启动的时候出现错误也可以用下述命令进行测试
[root@localhost ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfgNagios 3.1.2Copyright (c) 2009 Nagios Core Development Team and Community ContributorsCopyright (c) 1999-2009 Ethan GalstadLast Modified: 06-23-2009License: GPLWebsite: http://www.nagios.orgReading configuration data… Read main config file okay…Processing object config file ‘/usr/local/nagios/etc/objects/commands.cfg’…Processing object config file ‘/usr/local/nagios/etc/objects/contacts.cfg’…Processing object config file ‘/usr/local/nagios/etc/objects/timeperiods.cfg’…Processing object config file ‘/usr/local/nagios/etc/objects/templates.cfg’…Processing object config file ‘/usr/local/nagios/etc/objects/hosts.cfg’… Read object config files okay…Running pre-flight check on configuration data…Checking services… Checked 9 services.Checking hosts… Checked 5 hosts.Checking host groups… Checked 3 host groups.Checking service groups… Checked 0 service groups.Checking contacts… Checked 3 contacts.Checking contact groups… Checked 3 contact groups.Checking service escalations… Checked 0 service escalations.Checking service dependencies… Checked 0 service dependencies.Checking host escalations… Checked 0 host escalations.Checking host dependencies… Checked 0 host dependencies.Checking commands… Checked 26 commands.Checking time periods… Checked 5 time periods.Checking for circular paths between hosts…Checking for circular host and service dependencies…Checking global event handlers…Checking obsessive compulsive processor commands…Checking misc settings…Total Warnings: 0Total Errors: 0呵呵，没有错误，可能您在配置之前或多或少会出现问题的，根据相关错误提示，逐一排查，相信您定会成功的。
现在我们打开nagios的web页面，输入：http://***.com/nagios样例
先看map页面，大致页面如下
再看hosts相关链接页面：
最后，我们再看一下hostgroups页面：
二、客户端的配置：
1、需求软件的下载：
nagios插件程序：
nrpe软件：
2、软件的安装
(1) nagios插件的安装：
首先在安装前建立nagios用户，命令如下：
[root@yibaner src]# useradd nagios -s /sbin/nologin -M[root@yibaner src]# tar zxvf nagios-plugins-1.4.13.tar.gz[root@yibaner src]# cd nagios-plugins-1.4.13[root@yibaner nagios-plugins-1.4.13]# ./configure –prefix=/usr/local/nagios[root@yibaner nagios-plugins-1.4.13]# make && make install[root@yibaner nagios-plugins-1.4.13]# chown -R nagios.nagios /usr/local/nagios/(2) nrpe的程序的安装：
[root@yibaner src]# tar zxvf nrpe-2.12.tar.gz[root@yibaner nrpe-2.12]# cd nrpe-2.12[root@yibaner nrpe-2.12]# ./configure[root@yibaner nrpe-2.12]# make all[root@yibaner nrpe-2.12]# make install-plugin[root@yibaner nrpe-2.12]# make install-daemon[root@yibaner nrpe-2.12]# make install-daemon-config(3) 修改nrpe.cfg配置文件：
[root@yibaner nrpe-2.12]# vi /usr/local/nagios/etc/nrpe.cfg 将server_address的值修改为本机的IP地址：server_address=*.*.*.110将allowed_hosts的值修改为远程监控服务器的IP地址：allowed_hosts=*.*.*.27(4) 运行nrpe服务：
[root@yibaner nrpe-2.12]# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d(5) 查看nrpe运行情况：
[root@yibaner nrpe-2.12]# netstat -nap | grep nrpetcp 0 0 *.*.*.110:5666 0.0.0.0:* LISTEN 3538/nrpe
从上述情况来看，nrpe成功运行，并且占用了5666端口(6) 设置nrpe自启动：
[root@yibaner nrpe-2.12]#vi /etc/rc.local在其中加中此行：/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d(7) 在监控服务器端测试被监控服务器是否正常运行
[root@localhost src]# telnet *.*.*.110 5666测试如果一切正常，整个配置过程全部告一段落，只需到监控服务器中设置对被监控服务器的所需服务的监控即可。
这样一来，整个nagios的配置全部告一段落了，把被监控服务器的某个服务暂时停用一下，马上就会收到飞信的短消息了，一切表明，配置成功了。
