1、修改系统变量
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
2、保存生效
sysctl -p
3、查看内核是否已开启BBR
sysctl net.ipv4.tcp_available_congestion_control
显示以下即已开启:
# sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = bbr cubic reno
4、查看BBR是否启动
lsmod | grep bbr
显示以下即启动成功:
# lsmod | grep bbr
tcp_bbr 20480 14
