Linux-开启bbr加速

树莓派开启 bbr 加速

# 确保内核在4.9以上
sudo rpi-update

# 修改配置，开启 bbr 加速
sudo bash -c 'echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf'
sudo bash -c 'echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf'
sudo sysctl -p
sudo reboot

# 验证
sysctl net.ipv4.tcp_available_congestion_control
# 输出：net.ipv4.tcp_available_congestion_control = bbr cubic reno

lsmod | grep bbr
# 输出：tcp_bbr                20480  1
