谷歌的tcp-bbr拥堵算法,shadowsocks神器加buff
昨晚测试了tcp-bbr拥堵算法,效果看起来还是挺不错的。油管4k很稳定,8k可以播放。使用说明如下
1安装有bbr算法的内核
wget -O linux-image-4.9.0-amd64.deb http://kernel.ubuntu.com/~kernel-ppa/\
mainline/v4.9/linux-image-4.9.0-040900-generic_4.9.0-040900.201612111631_amd64.deb
dpkg -i linux-image-4.9.0-amd64.deb
2删除原来内核
dpkg -l|grep linux-image | awk '{print $2}' | grep -v 'linux-image-4.9.0-040900-generic'#列出原有内核
apt-get purge 旧内核名称#删除旧内核
update-grub #更新grub
reboot
3开启bbr
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p#使配置生效
4查看是否生效
sysctl net.ipv4.tcp_available_congestion_control
lsmod | grep bbr
5关闭bbr
sed -i '/net\.core\.default_qdisc=fq/d' /etc/sysctl.conf
sed -i '/net\.ipv4\.tcp_congestion_control=bbr/d' /etc/sysctl.conf
sysctl -p
reboot
6shadowsocks一键安装脚本
allinone版
wget --no-check-certificate https://raw.githubusercontent.com/teddysun/\
shadowsocks_install/master/shadowsocks-all.sh
chmod +x shadowsocks-all.sh
./shadowsocks-all.sh 2>&1 | tee shadowsocks-all.log
python版
wget --no-check-certificate https://raw.githubusercontent.com/teddysun/\
shadowsocks_install/master/shadowsocks.sh
chmod +x shadowsocks.sh
./shadowsocks.sh 2>&1 | tee shadowsocks.log
7说明
由于需要更换内核,需要kvm或xen架构的vps,openvz的不行,经测试,linode的开启失败,vultr的成果。
