centos安装mininet

#$install cgroup-tools || $install cgroup-bin
换成
$install libcgroup libcgroup-tools
yum -y install libcgroup libcgroup-tools

增加
test -e /etc/centos-release && DIST="CentOS"
if [ "$DIST" = "CentOS" ]; then
    install='sudo yum -y install'
    remove='sudo yum -y erase'
    pkginst='sudo rpm -ivh'
    # Prereqs for this script
    if ! which lsb_release &> /dev/null; then
        $install redhat-lsb-core
    fi
fi
test -e /etc/SuSE-release && DIST="SUSE Linux"

修改

DISTS='Ubuntu|Debian|Fedora|RedHatEnterpriseServer|SUSE LINUX'

DISTS='Ubuntu|Debian|Fedora|RedHatEnterpriseServer|SUSE LINUX|CentOS'
if ! echo $DIST | egrep "$DISTS" >/dev/null; then
    echo "Install.sh currently only supports $DISTS."
    exit 1

#mininet/util/install.sh[options]
这里典型的[options]主要有下面几种：
“-a”：完整安装包括Mininet VM，还包括如Open vSwitch的依赖关系，以及像的OpenFlow Wireshark分离器和POX。默认情况下，这些工具将被安装在你的home目录中。
“-nfv”：安装Mininet、基于OpenFlow的交换机和Open vSwitch。
“-s mydir” ：在其他选项使用前使用此选项可将源代码建立在一个指定的目录中，而不是在你的home目录。

# install.sh –a        ##完整安装（默认安装在home目录下）
# install.sh -s mydir –a        ##完整安装（安装在其他目录） 
# install.sh –nfv        ##安装Mininet+用户交换机+OVS（安装在home目录下）        
# install.sh -s mydir –nfv            ##安装Mininet+用户交换机+OVS（安装在其他目录下）
