一键安装脚本：

wget -N –no-check-certificate “https://raw.githubusercontent.com/chiakge/Linux-NetSpeed/master/tcp.sh” && chmod +x tcp.sh && ./tcp.sh

手动bbr

“`shell

echo “net.core.default_qdisc=fq” >> /etc/sysctl.conf

echo “net.ipv4.tcp_congestion_control=bbr” >> /etc/sysctl.conf

sysctl -p

查看bbr是否开启

sysctl net.ipv4.tcp_available_congestion_control

sysctl net.ipv4.tcp_congestion_control

查看bbr是否启动

lsmod | grep bbr
