魔改 BBR for Ubuntu-kernel-daily-20180105 #13

Closed nanqinlang closed 6 years ago

nanqinlang commented 6 years ago

why daily

default http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/CHANGES

that's why i choose a daily kernel to use.

enable tcp_nanqinlang

to enable tcp_nanqinlang for that kernel, you should run the following directive:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2018-01-05/linux-image-4.15.0-999-lowlatency_4.15.0-999.201801050201_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2018-01-05/linux-headers-4.15.0-999_4.15.0-999.201801050201_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2018-01-05/linux-headers-4.15.0-999-lowlatency_4.15.0-999.201801050201_amd64.deb

dpkg -i linux-image-4.15.0-999-lowlatency_4.15.0-999.201801050201_amd64.deb
dpkg -i linux-headers-4.15.0-999_4.15.0-999.201801050201_all.deb
apt-get install -y libelf1
dpkg -i linux-headers-4.15.0-999-lowlatency_4.15.0-999.201801050201_amd64.deb
update-grub

then, reboot your device, then run these:

wget https://github.com/nanqinlang-tcp/tcp_nanqinlang/releases/download/daily-20180105/tcp_nanqinlang.c

# debian7/8
wget -O Makefile https://raw.githubusercontent.com/nanqinlang-tcp/tcp_nanqinlang/master/Makefile/Makefile-Debian7or8
# debian9
wget -O Makefile https://raw.githubusercontent.com/nanqinlang-tcp/tcp_nanqinlang/master/Makefile/Makefile-Debian9

make && make install

echo -e "\nnet.core.default_qdisc=fq" >> /etc/sysctl.conf
echo -e "net.ipv4.tcp_congestion_control=nanqinlang\c" >> /etc/sysctl.conf
sysctl -p

@Love4Taylor
CentOS 那边的 PTI 是哪个版本内核更新的, 我还没去看呢

nanqinlang commented 6 years ago

there is a script:

wget https://github.com/nanqinlang-tcp/tcp_nanqinlang/releases/download/daily-20180105/tcp_nanqinlang-daily20180105.sh
bash tcp_nanqinlang-daily20180105.sh

requirement, only: Debian7+ 64bit KVM

usage:

  1. run first choice
  2. reboot
  3. run second choice
teochen commented 6 years ago

I don't know what's going wrong when I run second choice
