centos7安装netspeeder教程

方法一：
使用以下命令从github上下载安装脚本
wget --no-check-certificate https://gist.github.com/LazyZhu/dc3f2f84c336a08fd6a5/raw/d8aa4bcf955409e28a262ccf52921a65fe49da99/net_speeder_lazyinstall.sh
sh net_speeder_lazyinstall.sh

由于本机系统为centos7，安装时会遇到报错 \033[31m Error: Unable to Determine OS Version. \033[0m
查看脚本（less net_speeder_lazyinstall.sh）会发现脚本只定义了centos5和centos6的安装包，故而对7无法识别，只能报错

所以需要查看最新的centos7安装包的地址，登录网站http://dl.fedoraproject.org/pub/epel ， 我们看到地址centos7的安装包目前路径为
http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

因此用vi修改脚本 net_speeder_lazyinstall.sh
修改后脚本如下（本脚本增加了7的安装条件，由于7的/etc/release没有7等字眼，因此用判断OS Bit条件做替代，基本不影响）

#/bin/bash
export PATH

#Check If You Are Root
if [ $(id -u) != "0" ]; then
    clear
    echo -e "\033[31m Error: You must be root to run this script! \033[0m"
    exit 1
fi

if [ $(arch) == x86_64 ]; then
    OSB=x86_64
elif [ $(arch) == i686 ]; then
    OSB=i386
else
    echo "\033[31m Error: Unable to Determine OS Bit. \033[0m"
    exit 1
fi
if egrep -q "5.*" /etc/issue; then
    OST=5
    wget http://dl.fedoraproject.org/pub/epel/5/${OSB}/epel-release-5-4.noarch.rpm
elif egrep -q "6.*" /etc/issue; then
    OST=6
    wget http://dl.fedoraproject.org/pub/epel/6/${OSB}/epel-release-6-8.noarch.rpm
elif [ $(arch) == x86_64 ]; then
OST=7
    wget http://dl.fedoraproject.org/pub/epel/7/${OSB}/Packages/e/epel-release-7-11.noarch.rpm
else
    echo "\033[31m Error: Unable to Determine OS Version. \033[0m"
    exit 1
fi

rpm -Uvh epel-release*rpm
yum install -y libnet libnet-devel libpcap libpcap-devel gcc

wget http://net-speeder.googlecode.com/files/net_speeder-v0.1.tar.gz -O -|tar xz
cd net_speeder
if [ -f /proc/user_beancounters ] || [ -d /proc/bc ]; then
    sh build.sh -DCOOKED
    INTERFACE=venet0
else
    sh build.sh
    INTERFACE=eth0
fi

NS_PATH=/usr/local/net_speeder
mkdir -p $NS_PATH
cp -Rf net_speeder $NS_PATH
echo -e "\033[36m net_speeder installed. \033[0m"
echo -e "\033[36m Usage: nohup ${NS_PATH}/net_speeder $INTERFACE \"ip\" >/dev/null 2>&1 & \033[0m"

安装完后，按照提示的安装即可
nohup /usr/local/net_speeder/net_speeder eth0 “ip” >/dev/null 2>&1 &

方法二：
登陆官方作者的GitHub地址，按照作者的建议进行安装，以下内容转载自作者GitHub教程
https://github.com/snooda/net-speeder

安装步骤：
1：下载源码并解压

wget https://github.com/snooda/net-speeder/archive/master.zip
unzip master.zip
2：准备编译环境
debian/ubuntu：

#安装libnet-dev：
apt-get install libnet1-dev
#安装libpcap-dev：
apt-get install libpcap0.8-dev
centos：

#下载epel：https://fedoraproject.org/wiki/EPEL/zh-cn 例：CentOS6 64位：
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
如果是centos7, 使用如下脚本
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
#（如果是centos5，则在epel/5/下）
#安装epel：
#centos6
rpm -ivh epel-release-6-8.noarch.rpm
#centos7
rpm -ivh epel-release-7-11.noarch.rpm
#然后即可使用yum安装：
yum install libnet libpcap libnet-devel libpcap-devel
编译：ls -tlrh
Linux Cooked interface使用编译（venetX，OpenVZ）：
sh build.sh -DCOOKED
普通网卡使用编译（Xen，KVM，物理机）：
sh build.sh
使用方法(需要root权限启动）：

#参数：./net_speeder 网卡名 加速规则（bpf规则）
#ovz用法(加速所有ip协议数据)：
./net_speeder eth0 “ip”
