安装nagios图形（PNP）
1. 底层支持库（图形显示的依赖） yum install -y cairo pango zlib zlib-devel freetype freetype-devel gd gd-devel2. RRDTOOLS的支持软件libart_lgpl
yum install libart_lgpl
或者编译安装libart_lgpl-2.3.17
重要步骤：
cp -r libart-2.0 /usr/include/
3. 安装rrd-tools
./configure --prefix=/usr/local/rrdtool --disable-python --disable-tcl
4. 安装PNP
./configure --with-rrdtool=/usr/local/rrdtool/bin/rrdtool ----->真正出图的命令
--with-perfdata=/usr/local/nagios/share/perfdata ----->出图所用的数据路径
WARNING: The RRDs Perl Modules are not found on your System
Using RRDs will speedup things in larger Installtions.
警告不用理会。
详细安装记录：
978./configure --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata=/usr/local/nagios/share/perfdata
979make all
980make install
981make install-config
982make install-init
5. 至此，PNP及相关NAGIOS图形安装完毕
6. 配置command.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
}
7. 整合nagios和pnp的web显示页面
编辑host.cfg添加action_url 参数 或者编辑模板文件templates.cfg
action_url /nagios/pnp/index.php?host=$HOSTNAME$
再次整合services
/nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
