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

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

chmod +x ./dynamips-0.2.8-RC2-x86.bin

chmod +x ./dynamips-0.2.8-RC2-amd64.bin

8.运 行GNS3

python /opt/GNS3/gns3

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

Once PyQt4 was installed, GNS3 opened properly.

至此，在Fedora上可以运行GNS3了
