在Red Hat Enterprise Linux 5.3安装RRDTool

关于RRDTool的简单介绍：

RRDTool是由Tobias Oetiker开发的自由软件，它使用RRD（Round Robin Database）作为存储格式，Round robin是一种处理定量数据、以及当前元素指针的技术。RRDTool主要用来跟踪对象的变化情况，生成这些变化的走势图。

其实它和mrtg 是同一家族, 主要都是在产生time-series 的图档(如流量,负载,温度,人数.....),不过因为mrtg 当初的考量是画两种资料在图上(或四个值),后来原作者觉得不足,所以另外又开发了rrdtool, rrdtool 本身可和mrtg 结合,但其结合基本上仅在于将mrtg 的文字档的log 转成rrd 储存格式,通常user 尚需要mrtg-rrd/rrdcgi 去转换,不过总觉得美中不足,因为最终其实你用到的还是rrdtool,虽然还有像my14all (http://my14all.sourceforge.net/) 这类的tools可以转换并画图,但其追根究底还是以rrdtool 为base, 所以rrdtool 变成了最终也是最好的选择。

平心而论rrdtool 的学习远比mrtg 来得困难,且相关文件资料也没有mrtg多,其中中文的参考又几乎没有,如果没有较深厚的Linux 基础(尤其是Shell Script) 或了解SNMP,懂得英文及好学的心,否则是不建议学习rrdtool 的.因为你可能很难去控制或获得你所要的资料,亦可能难于表现图档。

当然,每个人看法不见得相同,完全看个人需要而定,就像用mrtg 画CPU Load, Memory Usage,HTTP Client, Process...., 纯使用mrtg 是较简单且好用的,但是你要做很多图,每张图之间的关联生基本上可能需要你用眼睛去判断.但如果使用rrdtool 可以让你四张叠成一张,如此也较好比较出其中的因果关系,不过此时你得懂得控制图的表现方式来达到显示上最好的结果.基本上学rrdtool 完全不需要有mrtg 的经验. 但最好对系统资讯获得的方法(cmd/ snmp/Shell Script )熟一点会较好处理.

RRDTool的优点：灵活，开放：

RRDTool的典型应用：

Cacti

NTOP

Nagios

SmokePing

RRDWeather 等等：（我下面就会有一篇博客来写关于NTOP的配置）

好了，下面开始安装我们的RRDTool：

安装RRDTool的时候经常出现一下问题：

如：我已经下载包所谓的rrdtool的rrdtool - 1.3.1.tar.gz包了。但是./ configure命令发放大量的错误提示信息。我要如何的在Red Hat Enterprise Linux 5.x - 64 安装RRDtool呢？

因为：RRD是Round Robin Database的缩写。RRD是一个系统用来存储和显示的时间序列数据（即网络带宽，机房温度，服务器的平均负载）。它存储数据在一个非常紧凑的方式，将不随时间变化的数据扩大，并提出了处理数据，以执行某种有用的数据密度图。它可以使用，也可以通过简单的包装脚本（shell或perl）或通过前端设备的调查网络，提供友好的用户界面。

下面介绍在RHEL上安装RRDTool。

为了在Red Hat Enterprise Linux上安装RRTool，您需要安装一些开发工具和库。

步骤1：安装需要依赖的包：

以root用户登录，然后输入一下命令：

#yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel

输入此命令后出出现以下信息：

Loaded plugins: rhnplugin

This system is not registered with RHN.

RHN support will be disabled.

步骤2：下载最新版本的RRDTool源码包

#cd /opt/
#wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz

#tar -zxvf rrdtool-1.3.1.tar.gz

#cd rrdtools

步骤3：编译和安装RRDTool：

您需要设置PKG_CONFIG_PATH，请输入

#export PKG_CONFIG_PATH=/usr/lib/pkgconfig/

#./configure

现在，在RHEL上编译和安装RRDTool。

#make
#make install
#cd /usr/local/
#ln -s rrdtool-1.3.1/ rrdtool/
#cd rrdtool
#ls –l

如何验证我的安装呢？

现在RRDTool已经安装上了，并且已经准备好，可以被使用了。您可以到/usr/local/rrdtool/share/rrdtool/examples/ directory下运行它们去查看你是否成功安装了RRDTool？

#cd /usr/local/rrdtool/share/rrdtool/examples/
#./stripes.pl
#ls -l
#cp stripes.png /var/www/html/ （这一步骤的前提是你本机是个WWW服务器器）

在浏览器中输入http://your-domain.com/stripes.png ，看看自己的图形；

出现以上图，说明我们的安装是成功的。

***可选编译时间设置*****

默认情况下RRDTool将安装在/usr/local/rrdtool-1.3.1/ directory。 如果想修改默认安装目录，使用一下命令安装：

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

使用一下命令，让您查看所有编译设置选项：

#./configure -help

输出一下信息：

`configure' configures rrdtool 1.3.1 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as

VAR=VALUE. See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:

-h, --help display this help and exit

--help=short display options specific to this package

--help=recursive display the short help of all the included packages

-V, --version display version information and exit

-q, --quiet, --silent do not print `checking...' messages

--cache-file=FILE cache test results in FILE [disabled]

-C, --config-cache alias for `--cache-file=config.cache'

-n, --no-create do not create output files

--srcdir=DIR find the sources in DIR [configure dir or `..']

Installation directories:

--prefix=PREFIX install architecture-independent files in PREFIX

[/usr/local/rrdtool-1.3.1]

--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX

[PREFIX]

By default, `make install' will install all the files in

`/usr/local/rrdtool-1.3.1/bin', `/usr/local/rrdtool-1.3.1/lib' etc. You can specify

an installation prefix other than `/usr/local/rrdtool-1.3.1' using `--prefix',

for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:

--bindir=DIR user executables [EPREFIX/bin]

--sbindir=DIR system admin executables [EPREFIX/sbin]

--libexecdir=DIR program executables [EPREFIX/libexec]

--sysconfdir=DIR read-only single-machine data [PREFIX/etc]

--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

--localstatedir=DIR modifiable single-machine data [PREFIX/var]

--libdir=DIR object code libraries [EPREFIX/lib]

--includedir=DIR C header files [PREFIX/include]

--oldincludedir=DIR C header files for non-gcc [/usr/include]

--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

--datadir=DIR read-only architecture-independent data [DATAROOTDIR]

--infodir=DIR info documentation [DATAROOTDIR/info]

--localedir=DIR locale-dependent data [DATAROOTDIR/locale]

--mandir=DIR man documentation [DATAROOTDIR/man]

--docdir=DIR documentation root [DATAROOTDIR/doc/rrdtool]

--htmldir=DIR html documentation [DOCDIR]

--dvidir=DIR dvi documentation [DOCDIR]

--pdfdir=DIR pdf documentation [DOCDIR]

--psdir=DIR ps documentation [DOCDIR]

Program names:

--program-prefix=PREFIX prepend PREFIX to installed program names

--program-suffix=SUFFIX append SUFFIX to installed program names

--program-transform-name=PROGRAM run sed PROGRAM on installed program names

System types:

--build=BUILD configure for building on BUILD [guessed]

--host=HOST cross-compile to build programs to run on HOST [BUILD]

--target=TARGET configure for building compilers for TARGET [HOST]

Optional Features:

--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)

--enable-FEATURE[=ARG] include FEATURE [ARG=yes]

--enable-maintainer-mode enable make rules and dependencies not useful

(and sometimes confusing) to the casual installer

--disable-rrdcgi disable building of rrdcgi

--disable-mmap disable mmap in rrd_update, use seek+write instead

--disable-pthread disable multithread support

--enable-static-programs Build static programs

--disable-dependency-tracking speeds up one-time build

--enable-dependency-tracking do not reject slow dependency extractors

--enable-shared[=PKGS] build shared libraries [default=yes]

--enable-static[=PKGS] build static libraries [default=yes]

--enable-fast-install[=PKGS]

optimize for fast installation [default=yes]

--disable-libtool-lock avoid locking (might break parallel builds)

--disable-libintl i18n support (libintl)

--disable-perl do not build the perl modules

--enable-perl-site-install by default the rrdtool perl modules are installed

together with rrdtool in $prefix/lib/perl. You have to

put a 'use lib qw($prefix/lib/perl)' into your scripts

when you want to use them. When you set this option

the perl modules will get installed wherever

your perl setup thinks it is best.

--disable-ruby do not build the ruby modules

--enable-ruby-site-install by default the rrdtool ruby modules are installed

together with rrdtool in $prefix/lib/ruby. You have to

add $prefix/lib/ruby/$ruby_version/$sitearch to you $: variable

for ruby to find the RRD.so file.

--disable-tcl do not build the tcl modules

--enable-tcl-site install the tcl extension in the tcl tree

--disable-python do not build the python modules

Optional Packages:

--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]

--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)

--with-rrd-default-font=OPTIONS set the full path to your default font.

--with-gnu-ld assume the C compiler uses GNU ld [default=no]

--with-pic try to use only PIC/non-PIC objects [default=use

both]

--with-tags[=TAGS] include additional configurations [automatic]

--with-perl-options=OPTIONS options to pass on command-line when

generating Makefile from Makefile.PL. If you set this

option, interesting things may happen unless you know

what you are doing!

--with-ruby-options=OPTIONS options to pass on command-line when

generating Makefile from extconf.rb. If you set this

option, interesting things may happen unless you know

what you are doing!

--with-tcllib=DIR location of the tclConfig.sh
