为内核加载 bbr 模块
echo "tcp_bbr" > /etc/modules-load.d/modules.conf将默认的拥塞算法设置为 bbr
echo "net.core.default_qdisc=fq" > /etc/sysctl.d/bbr.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.d/bbr.conf重启服务器后验证一下
sysctl net.ipv4.tcp_congestion_control
net.ipv4.tcp_congestion_control = bbr打开bbr后，网站速度感觉快了一些
