net-speeder网速优化器一键安装脚本
net-speeder是一个由snooda.com博主写的Linux脚本程序,主要目的是为了解决丢包问题,实现TCP双倍发送,即同一份数据包发送两份。这样的话在服务器带宽充足情况下,丢包率会平方级降低。
1、net-speeder相关介绍
项目主页:https://code.google.com/p/net-speeder
net-speeder对于不加速就可以跑满带宽的类型来讲(多线程下载),开启后反而由于多出来的无效流量,导致速度减半,性能开销稍大和自由度有损失。所以,如果你的VPS连接国内速度一切正常,请不要启用net-speeder。
2、安装net-speeder
系统要求:CentOS 5/6 32or64bit
安装net-speeder的方法也很简单,这里提供由lazyzhu.com博主写的net-speeder一键安装包。执行以下命令:
- wget --no-check-certificate https://gist.github.com/LazyZhu/dc3f2f84c336a08fd6a5/raw/d8aa4bcf955409e28a262ccf52921a65fe49da99/net_speeder_lazyinstall.sh
- sh net_speeder_lazyinstall.sh
3、启用
安装完成后,会给出脚本用法,最简单的就是开启所有IP协议加速。执行以下命令:
- nohup /usr/local/net_speeder/net_speeder venet0 "ip" >/dev/null 2>&1 &
4、如果上面的安装地址失效,则给出脚本代码,自行放到服务器上做成sh文件使用:
- #!/bin/sh
- # Set Linux PATH Environment Variables
- PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
- 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
- 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"
至于该插件是否有效果现在还无法下结论,如果发现你的VPS搭建SS账号一切正常可不用尝试,本人使用的日本Linode在使用后速度提升了20%左右。仅作参考。
