1 NS-3概述

官网:https://www.nsnam.org/

ns-3 is a discrete-event network simulator for Internet systems, targeted primarily for research and educational use. ns-3 is free software, licensed under the GNU GPLv2 license, and is publicly available for research, development, and use.ns-3是用于因特网系统的离散事件网络模拟器,主要用于研究和教育用途。ns-3是免费软件,根据GNU GPLv2许可证授权,可公开用于研究,开发和使用。

介绍完NS-3的用途接下来就是安装教程啦~

注意:本实验所有操作通过虚拟机直接进入root用户进行操作,默认所有操作都在root权限下进行。


2 平台安装

2.1 安装ns-3的依赖环境

yum install gcc-c++ python

yum install python-devel

yum install mercurial 

yum install doxygen graphviz ImageMagick

yum install python-sphinx dia texlive texlive-latex

yum install openmpi openmpi-devel

yum install tcpdump wireshark

yum install sqlite sqlite-devel

yum install libxml2 libxml2-devel

yum install boost-devel 

yum install graphviz graphviz-devel python-setuptools-devel ipython

sudo easy_install pygraphviz

yum install goocanvas pygtk2-devel

 

Then obtain the RPM for pygoocanvas andpygoocanvas-devel from here: http://li.nux.ro/download/nux/dextop/el6/x86_64/

在上面网址下载pygoocanvas-0.14.1-3.el6.nux.x86_64.rpm和pygoocanvas-devel-0.14.1-3.el6.nux.x86_64.rpm,放入/root/packages文件夹中,用rpm进行安装时要在包前加上文件路径。

rpm -ivh /root/packages/pygoocanvas-0.14.1-3.el6.nux.x86_64.rpm --nodeps --force

rpm -ivh /root/packages/pygoocanvas-devel-0.14.1-3.el6.nux.x86_64.rpm --nodeps --force

 

yum install git

yum install gsl gsl-devel

yum install gtk2 gtk2-devel

yum install gdb valgrind

 

2.2 Downloading ns-3

创建文件夹:[root@localhost ~]# mkdir tarballs

进入tarballs:[root@localhost ~]# cd tarballs

联网下载: [root@localhost tarballs]# wget http://www.nsnam.org/releases/ns-allinone-3.21.tar.bz2

解压:[root@localhost tarballs]# tar jxvf ns-allinone-3.21.tar.bz2

进入ns-allinone-3.21[root@localhost tarballs]# cd ns-allinone-3.21

构建安装:[root@localhost ns-allinone-3.21]# ./build.py

进入ns-3.21:[root@localhost ns-allinone-3.21]# cd ns-3.21

使用waf编译安装,使用test.py测试,运行脚本测试:

[root@localhost ns-3.21]# ./test.py

[root@localhost ns-3.21]# ./waf distclean

[root@localhost ns-3.21]# ./waf --build-profile=debug --enable-examples --enable-tests configure

[root@localhost ns-3.21]# ./waf

[root@localhost ns-3.21]# ./test.py -c core

[root@localhost ns-3.21]# ./waf --hello-simulator

通过以上代码和部分压缩吧可以搭建好ns-3.21的环境,接下来是安装eclipse。


3 Eclipse配置

3.1 安装Eclipse

(1)测试一下是否已安装jdk:# java -version

         一般centos7已经安装jdk 8.0,如果没安装,在root用户下,输入命令yum install java

(2)下载eclipse:# wget http://mirrors.neusoft.edu.cn/eclipse/technology/epp/downloads/release/luna/SR2/eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz

(3)新建一个eclipse文件夹保存下载压缩包:

         # mkdir eclipse

         # mv /root/eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz /root/eclipse

(4)将eclipse压缩包解压到/opt目录下:

         # cd eclipse 

         # tar -zxvf eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz -C/opt

(5)建立软连接(等同于快捷方式):

         # ln -s /opt/eclipse/eclipse /usr/bin/eclipse

(6)为 Eclipse 设置桌面启动:

         # vim /usr/share/applications/eclipse.desktop

         并在文件中添加如下内容:

[Desktop Entry]
Encoding=UTF-8
Name=Eclipse 4.4.1
Comment=Eclipse Luna 
Exec=/usr/bin/eclipse
con=/opt/eclipse/icon.xpm
Terminal=false
Version=1.0
Type=Application
Categories=Application;Development;Java;IDE


:wq保存退出

(7)Eclipse安装完成,可在应用程序——编程中查看

点击Add

Nmae:cdt

Location:http://download.eclipse.org/tools/cdt/releases/kepler

点击ok后,再点击右下方next按照需要选择组件继续向下安装即可。

3.3 配置

(1)新建一个C++Project,我将其name命名为homework,这个项目的路径是:/root/workspace/homework

将/root/tarballs/ns-allinone-3.21/ns-3.21目录下的所有文件,全部复制到homework目录中,在eclipse中刷新构建该项目。

(2)进入ns-3.21目录,执行waf配置:

# cd /root/tarballs/ns-allinone-3.21/ns-3.21

# ./waf --build-profile=debug --enable-examples --enable-tests configure

(3)回到eclipse,右击项目homework,选择properties,点击C/C++ build

Centos7下的NS-3安装与配置总结(超详细!超完整!)_第5张图片

Build command栏中改写为:${workspace_loc:/homework/waf}

Build directory栏中改写为:${workspace_loc:/homework/build}

点击上方的behaviour,将all改为build

点击apply,ok完成应用设置。

(4)右击homework项目,选择debug as --> debug configure --> 选择C/C++ application

修改C/C++ Application:build/scratch/scratch-simulator

再选Environment,添加如下信息:

Variable:LD_LIBRARY_PATH

Value:${workspace_loc:/homework/build}

至此,eclips配置成功。


4 脚本运行

4.1 终端编译运行

(1)将编写的脚本(first.cc和second.cc)复制到/root/tarballs/ns-allinone-3.21/ns-3.21/scratch目录下,可以在centos7窗口界面直接复制;然后,进入ns3目录:# cd /root/tarballs/ns-allinone-3.21/ns-3.21

(2)构建(编译):# ./waf

(3)运行脚本

运行first.cc脚本:# ./waf --run scratch/first

运行second.cc脚本:# ./waf --run scratch/second

4.2 Eclipse编译运行

(1)将编写的脚本(first.cc和second.cc)复制到/root/workspace/homework/scratch目录下,刷新构建该工程。

(2)右击homework项目,选择debug as --> debug configure --> 选择C/C++ application

修改C/C++ Application:build/scratch/first

然后点击apply应用于该项目。

5 可视化界面

PyViz是一个用Python开发的在线ns-3可视化工具,不需要使用trace文件

5.1 PyViz安装

(1)首先需要检查机器上是否有epel仓库,因为会用到里面的一些包。如果有结果则从(2)开始向下进行,如果无显示则表明本机无epel仓库需要继续执行后续操作。

检查epel仓库:# rpm -qa | grep epel

安装epel:# yum -y install epel-release

查看仓库信息:# yum repolist

(2)安装该模块依赖的软件包

# yum install python-devel gnome-python2 gnome-python2-gnomedesktop gnome-python2-rsvg graphviz-python pygoocanvas python-kiwi graphviz-devel

(红色字体的包我没有在yum,epel源中找到,暂时不知是否会对以后操作有影响,所以暂且搁置。做完回来发现这三个包即使没有找到未安装,最后的可视化界面也能出来,还是没有搞懂,我还是自己再研究研究吧。)

# yum install python

# yum install ipython

# yum install mock

# useradd -s /sbin/nologin mockbuild

# yum install cmake glibc-devel  glibc-devel

# easy_install pygraphviz

(3)下载pyviz

pyviz下载网址:http://code.nsnam.org/gjc/

# tar -xzvf ns-3-pyviz-d26a12d3ebb8.tar.gz

解压后将文件夹放在/root/tarballs/ns-allinone-3.21/ns-3.21/目录下,再重新编译如下命令:

# ./waf clean

# ./waf --build-profile=debug --enable-examples --enable-tests configure

(4)用如下命令可以测试是否安装成功:

# ./waf --pyrun src/flow-monitor/examples/wifi-olsr-flowmon.py --visualize

若安装成功则会出现下图:

5.2 PyViz使用

(1)修改脚本

首先,到/root/tarballs/ns-allinone-3.21/ns-3.21/scratch找到first.cc和second.cc;

然后,双击打开这两个脚本,看文件中是否有以下两句,如果没有则添加到两文件的指定位置:

CommandLine cmd;
cmd.Parse(argc,argv);

6 总结

拖拖拉拉好长时间终于将NS-3的总体框架搭建成功了~希望对大家的学习有所帮助,有问题可以评论,我会尽力帮大家解决哒~

That is all.
