GNS3 on Centos / Redhat / Fedora源码安装

  1.安装必要的软件包
yum install python python-devel xorg-x11-proto-devel libXext-devel
yum install gcc-c++

2.下载qt4、pyqt4、sip4,这几个包可以在我的服务器上下载
cd /tmp
wget http://61.160.250.243:1000/GNS3/GNS3-0.7.2-src.tar.bz2
wget http://61.160.250.243:1000/GNS3/PyQt-x11-gpl-4.5.2.tar.gz
wget http://61.160.250.243:1000/GNS3/qt-x11-opensource-src-4.5.1.tar.gz
wget http://61.160.250.243:1000/GNS3/sip-4.8.1.tar.gz

3.编译Qt4
cd /tmp
tar zxvf qt-x11-opensource-src-4.5.1.tar.gz
cd qt-x11-opensource-src-4.5.1
./configure -nomake examples -nomake demos -qt-gif -no-exceptions -debug -qt3support //等几分钟
gmake   //等吧，1小时-3小时不等
gmake install    //继续等，30分钟或者更长
export PATH=/usr/local/Trolltech/Qt-4.5.1/bin:$PATH





4.编译sip
cd /tmp
tar zxvf sip-4.8.1.tar.gz
cd sip-4.8.1
python configure.py
make
make install


5.编译PyQt
cd /tmp
tar zxvf PyQt-x11-gpl-4.5.2.tar.gz
cd PyQt-x11-gpl-4.5.2
python configure.py
make   //继续等，差不多30分钟以上
make install

  


6.安装GNS3
cd /tmp
tar jxvf GNS3-0.7.2-src.tar.bz2 -C /opt
mv /opt/GNS3-0.7.2-src /opt/GNS3

7.创建几个目录
mkdir /opt/GNS3/Dynamips
mkdir /opt/GNS3/IOS
cd /opt/GNS3/Dynamips
wget http://www.ipflow.utc.fr/dynamips/dynamips-0.2.8-RC2-x86.bin    //for 32bit
chmod +x ./dynamips-0.2.8-RC2-x86.bin
wget http://www.ipflow.utc.fr/dynamips/dynamips-0.2.8-RC2-amd64.bin //for 64bit
chmod +x ./dynamips-0.2.8-RC2-amd64.bin

8.运 行GNS3
python /opt/GNS3/gns3

原作者：探险者  谢谢分享

按照上述方法运行python /opt/GNS3/gns3会提示：

[root@localhost GNS3]# ./gns3
Can't import Qt modules, PyQt is probably not installed ...

解决方法：

I’ve finally decided to move away from configuring all my emulators on the CLI and use GNS3.  The primary reason for using a GUI over the CLI is ease-of-use.  Whenever I run into a unique routing problem or need to conduct a proof of concept on a technology at work, I found that the whole process of generating a .net configuration was time consuming.  Using GNS3 allows me to quickly point-and-click my way to a new scenario in just minutes.

After downloading the source files, I attempted to run ./gns3 and encountered the following error message:

[root@CTSLA-NMS19 GNS3-0.6-src]# ./gns3
Can’t import Qt modules, PyQt is probably not installed …

To satisfy the installation requirements, I needed to install or update a few of the dependencies:

[root@CTSLA-NMS19 GNS3-0.6-src]# yum -y install python sip qt4 PyQt4

[root@localhost GNS3]# yum -y install python sip qt4 PyQt4
已加载插件：presto, refresh-packagekit

完毕！

Once PyQt4 was installed, GNS3 opened properly.

至此，在Fedora上可以运行GNS3了，看截图：
