*** 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
# tar xvf rrdtool-1.4.7.tar.gz
# cd 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：
# cat dag.repo
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
#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：
#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：
#wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz
#tar -zxvf rrdtool-1.3.1.tar.gz
#cd rrdtool-1.3.1
#./configure --prefix=/usr/local/rrdtool && make && make install
#ln -s /usr/local/rrdtool/bin/* /usr/bin/
运行rrdtool –v测试安装成功没有：
#rrdtool -v //可以看到RRDTool的用法以及版本信息
下载pnp
# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata/
# make all
# make install
# make install-config
# make install-init
配置PNP
# pwd
/share/softwares/nagios/pnp-0.4.14/sample-config/pnp
# ls
background.pdfconfig.php npcd.cfg-sample pages pnp4nagios_release.in process_perfdata.cfg-sample.in

# cp process_perfdata.cfg-sample

# cp process_perfdata.cfg-sample /usr/local/nagios/etc/pnp/process_perfdata.cfg
# cp npcd.cfg-sample /usr/local/nagios/etc/pnp/npcd.cfg
# cp rra.cfg-sample /usr/local/nagios/etc/pnp/rra.cfg
# 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

# 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,# /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：
# cat /etc/passwd|grep nagios
nagios:x:503:503::/home/nagios:/sbin/nologin
