安装编译环境
1 2 | yum install -y ncurses-devel make gcc bc bison flex elfutils-libelf-devel openssl-devel rpm-build yum install -y dpkg-dev #生成deb包依赖 |
ubuntu下:
1 | apt install build-essential libncurses-dev flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf |
下载4.14版内核:
1 2 | tar xf linux-4.14.158.tar.xz |

下载tcp_bbrplus源码:
1 | wget -P net /ipv4/ https: //raw .githubusercontent.com /cx9208/bbrplus/master/tcp_bbrplus .c |
打开编译选项并开启编译bbr为模块:
1 | make menuconfig |
禁用签名调试:
1 2 | scripts /config --disable MODULE_SIG scripts /config --disable DEBUG_INFO |
编译内核生成centos rpm或ubuntu deb包,注意如果使用make rpm-pkg则每次编译前会先clean,如果重复编译会很慢!
1 2 | make binrpm-pkg -j4 make bindeb-pkg -j4 |
开启bbrplus:
1 2 3 | echo "net.core.default_qdisc=fq" >> /etc/sysctl .conf echo "net.ipv4.tcp_congestion_control=bbrplus" >> /etc/sysctl .conf sysctl -p |
ubuntu系统禁止更新内核:
1 2 3 4 | for pkg in $(dpkg -l| awk '/linux-(generic|headers|image|libc|modules)/{print $2}' ); do echo $pkg; apt-mark hold $pkg; done |
20210102更新:
由于4.14内核过于老旧,新系统使用会出现兼容性问题,且新内核bbr也一直在更新优化,建议下载安装最新的内核使用。

大佬,请问debian9编译错误怎么解决? github有人提问,没人解答,只好来这里看看.

不清楚,可尝试使用ubuntu18.04系统按本文方法编译试试。
