*** Config files installed ***
Remember, these are *SAMPLE* config files. You'll need to read
the documentation for more information on how to actually define
services, hosts, etc. to fit your particular needs.

安装rrdtool工具
wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz
[root@mysql nagios]# tar xvf rrdtool-1.4.7.tar.gz
[root@mysql nagios]# cd rrdtool-1.4.7
[root@mysql rrdtool-1.4.7]# ./configure --prefix=/usr/local/rrdtool
一、使用yum安装：
在 /etc/yum.repos.d/下面新建dag.repo文件在文件中输入源地址：
[root@hmg2 yum.repos.d]# cat dag.repo
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1
[root@hmg2 yum.repos.d]#yum -y install rrdtool
这样就可以完成RRDTool安装……
二、软件包安装：
先yum安装所要的库文件：
[root@hmg2 yum.repos.d]#yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel
然后下载rrdtool包，安装：
[root@hmg2 src]#wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz
[root@hmg2 src]#tar -zxvf rrdtool-1.3.1.tar.gz
[root@hmg2 src]#cd rrdtool-1.3.1
[root@hmg2 src]#./configure --prefix=/usr/local/rrdtool && make && make install
[root@hmg2 src]#ln -s /usr/local/rrdtool/bin/* /usr/bin/
运行rrdtool –v测试安装成功没有：
[root@hmg2 src]#rrdtool -v //可以看到RRDTool的用法以及版本信息
下载pnp
[root@mysql pnp-0.4.14]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata/
[root@mysql pnp-0.4.14]# make all
[root@mysql pnp-0.4.14]# make install
[root@mysql pnp-0.4.14]# make install-config
[root@mysql pnp-0.4.14]# make install-init
配置PNP
[root@mysql pnp]# pwd
/share/softwares/nagios/pnp-0.4.14/sample-config/pnp
[root@mysql pnp]# ls
background.pdf config.php npcd.cfg-sample pages pnp4nagios_release.in process_perfdata.cfg-sample.in
check_commands config.php.in npcd.cfg-sample.in pnp4nagios_release process_perfdata.cfg-sample rra.cfg-sample
[root@mysql pnp]# cp process_perfdata.cfg-sample
process_perfdata.cfg-sample process_perfdata.cfg-sample.in
[root@mysql pnp]# cp process_perfdata.cfg-sample /usr/local/nagios/etc/pnp/process_perfdata.cfg
[root@mysql pnp]# cp npcd.cfg-sample /usr/local/nagios/etc/pnp/npcd.cfg
[root@mysql pnp]# cp rra.cfg-sample /usr/local/nagios/etc/pnp/rra.cfg
[root@mysql pnp]# chown -R nagios.nagios /usr/local/nagios/etc/pnp/
vim /usr/local/nagios/etc/pnp/process_perfdata.cfg
LOG_LEVEL = 2 (修改)
下载 NRPE
http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.13/nrpe-2.13.tar.gz
[root@mysql nrpe-2.13]# make all

[root@mysql etc]# /usr/local/nagios/bin/nrpe -d /usr/local/nagios/etc/nrpe.cfg -d
[root@mysql etc]# netstat -ntlp|grep 5666

错误处理：
1，nagios web界面提示
It appears as though you do not have permission to view information for any of the services you requested...
打开cgi.cfg配置文件，里面有个参数:
use_authentication=1
为了保障系统的安全性，nagios设置了这个参数，默认为1,改为0即可。
2,[root@mysql etc]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios:This account is currently not available.
done.
这个引起：
[root@mysql etc]# cat /etc/passwd|grep nagios
nagios:x:503:503::/home/nagios:/sbin/nologin
