[root@CentOS1 dynamips-0.2.8-RC3-community]# make && make install
（若为64位系统，先执行export DYNAMIPS_LIB=lib64和export DYNAMIPS_ARCH=amd64在make&&make install ）
5、安装GNS3
[root@CentOS1 src]# tar zxvf GNS3-0.8.3.1-src.tar.gz
[root@CentOS1 src]# cd GNS3-0.8.3.1-src
[root@CentOS1 GNS3-0.8.3.1-src]# python setup.py install
6、启动GNS3
6.1、添加IOS镜像
6.2、测试dynamips
6.3、添加设备
注释掉下面两行，重启GNS3即可
[root@CentOS1 GNS3-0.8.3.1-src]# vim /usr/lib/python2.6/site-packages/GNS3/Node/AbstractNode.py
62 #if QtCore.QT_VERSION >= 0x040600:
63 # flags = flags | self.ItemSendsGeometryChanges
6.4、设置配置终端
