安装所需环境：yum install gcc libxml2-devel libpng-devel pkg-config glib pixman pango pango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel libart_lgpl-devel

2.下载安装包

wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz

# tar zxvf rrdtool-1.4.5.tar.gz

# cd rrdtool-1.4.5

# ./configure --prefix=/usr/local/rrdtool

# make

# make install

在安装过程中，出现

configure: error: Please fix the library issues listed above and try again错误

(1)安装 cgilib-0.5.tar.gz

#wget http://download.chinaunix.net/down.php?id=2531&ResourceID=1333&site=1

#tar zxvf cgilib-0.5.tar.gz

#cd cgilib-0.5

#make

#cp libcgi.a /usr/local/lib

#cp cgi.h /usr/include

(2)安装libart_lgpl-devel这个包

#yum –y install libart_lgpl-devel

(3)如果还报错,把这两个包装上pango-devel cairo-devel

# yum –y install pango-devel* cairo-devel*

#cd cd rrdtool-X.X.X

#./configure --prefix=/usr/local/rrdtool

(4)如果还是不行的话，试试yum install libxml2-devel

重新make可以先make clean

3.如何验证是否安装成功

pnp安装

1.安装pnp

wget http://nchc.dl.sourceforge.net/project/pnp4nagios/PNP/pnp-0.4.14/pnp-0.4.14.tar.gz

2.安装pnp报错

#./configure --with-nagios-user=nagios --with-nagios-group-nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata --with-perl_lib_path/usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/

configure: WARNING: Perl Module RRDs not available

解决方法

#cd /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi

#cp RRDs.pm /usr/lib/perl5/5.8.8/i386-linux-thread-multi/

#cp /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/auto/RRDs/RRDs.so /usr/lib/perl5/5.8.8/i386-linux-thread-multi/

重新./configure

[root@localhost pnp4nagios-0.6.20]#./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group-nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata --with-perl_lib_path=/usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/

3.安装完成，PNP默认文件放置情况如下：

*** Configuration summary for pnp 0.4.14 05-02-2009 ***

General Options:

------------------------- -------------------

Nagios user/group: nagios nagios

Install directory: /usr/local/nagios

HTML Dir: /usr/local/nagios/share/pnp

Config Dir: /usr/local/nagios/etc/pnp

Location of rrdtool binary: /usr/local/rrdtool/bin/rrdtool Version 1.4.7

RRDs Perl Modules: FOUND (Version 1.4007)

RRDs Perl search path: /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/

RRD Files stored in: /usr/local/nagios/share/perfdata

process_perfdata.pl Logfile: /usr/local/nagios/var/perfdata.log

Perfdata files (NPCD) stored in: /usr/local/nagios/var/spool/perfdata/

4.设置PNP

① 创建默认配置文件

cd /usr/local/nagios/etc/pnp

cp process_perfdata.cfg-sample process_perfdata.cfg 此文件无sample文件，将源文件备份即可

cp npcd.cfg-sample npcd.cfg

cp rra.cfg-sample rra.cfg

[root@localhost pnp]# chown -R nagios:nagios /usr/local/pnp4nagios/etc/

② 修改process_perfdata.cfg文件

vi /usr/local/nagios/etc/pnp/process_perfdata.cfg

LOG_FILE = /usr/local/nagios/var/perfdata.log

# Loglevel 0=silent 1=normal 2=debug

LOG_LEVEL = 2

这里将日志级别改为2,即为debug模式。

5.修改nagios配置文件

①增加小太阳标示

修改templates.cfg，增加一个定义PNP的hosts和services

define host {

name hosts-pnp

action_url /nagios/pnp/index.php?host=$HOSTNAME$

process_perf_data 1

}

define service {

name services-pnp

action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$

process_perf_data 1

}

②修改nagios.cfg

找到如下几项，去掉注释，修改后信息如下：

process_performance_data=1

host_perfdata_command=process-host-perfdata

service_perfdata_command=process-service-perfdata

③修改commands.cfg

# 'process-host-perfdata' command definition

define command{

command_name process-host-perfdata

command_line /usr/local/nagios/libexec/process_perfdata.pl

}

# 'process-service-perfdata' command definition

define command{

command_name process-service-perfdata

command_line /usr/local/nagios/libexec/process_perfdata.pl

}

④修改hosts.cfg文件和services.cfg文件

define host{

use linux-server,hosts-pnp

host_name web

alias ixdba-web

address 192.168.12.251

}

define host{

use linux-server,hosts-pnp

host_name MySQL

alias ixdba-mysql

address 192.168.12.237

}

define service{

use local-service,services-pnp

host_name mysql

service_description SSH

check_command check_ssh

}

define service{

use local-service,services-pnp

host_name web

service_description http

check_command check_http

}

6.测试PNP功能

所有配置完成之后，重新检查nagios配置文件是否正确，然后重启nagios

/etc/init.d/nagios restart

如果配置正确，此时就会生成响应主机的pnp文件

[root@nagios web]# pwd

/usr/local/nagios/share/perfdata/web

[root@gaojf web]# ls

http.rrd http.xml PING.rrd PING.xml SSHD.rrd SSHD.xml

最后打开网页：

打开网页http://IP/nagios，选择主机选项，然后点击小太阳就可以看到图表，或者访问http://ip/nagios/pnp也可以直接访问图表信息。

进入监控界面，点击监控主机的小太阳提示一下错误

PHP zlib Support not found.

PHP GD Support not found.

（1）由于编译PHP时候未将zlib,gd编译进PHP中，需要重新编译PHP 添加参数--with-zlib,--with-gd

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-zlib --with-gd

（2）安装完PHP提示

You may want to add: /usr/local/php/lib/php to your php.ini include_path

/root/rpm/php-5.3.23/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin

ln -s -f /usr/local/php/bin/phar.phar /usr/local/php/bin/phar

Installing PDO headers: /usr/local/php/include/php/ext/pdo/

解决方法：cp php.ini-production /usr/local/php/lib/php.ini
