Linux安装BBR BBR是google的TCP阻塞控制算法，可以最大程度的利用带宽，提升网络传输速率。Linux kernel 4.9 及以上已支持 tcp_bbrBBR一键安装脚本wget --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh && chmod +x bbr.sh && ./bbr.sh 1.查看系统内核版本：uname -r 看内核版本是否大于等于4.9，否则要升级内核，或者安装bbr。2.开启BBR：echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf 3.保存生效：sysctl -p 4.检查BBR是否启用：sysctl net.ipv4.tcp_available_congestion_control 返回值一般为： net.ipv4.tcp_available_congestion_control = reno cubic bbr sysctl net.ipv4.tcp_congestion_control 返回值一般为： net.ipv4.tcp_congestion_control = bbr sysctl net.core.default_qdisc 返回值一般为： net.core.default_qdisc = fq lsmod | grep bbr 返回值有类似：tcp_bbr 20480 10 则BBR模块已启动
