注意事项

确保安装了所需软件:

Debian/Ubuntu:

apt-get install -y gawk sed grep

RedHat/CentOS:

yum install -y gawk sed grep

如果出现了错误,请运行:

Debian/Ubuntu:

apt-get update

RedHat/CentOS:

yum update

在安装Ubuntu时,可能会遇到:

Getting the time form a network time server...

界面进度条很长时间不会动,可以等待它超时或者更换别的版本.
该问题是Ubuntu系统的问题.
前面有介绍过通过升级 Linux Kernel 内核升级到 4.9 及以上版本实现 BBR 加速的,由于 Debian9 默认的内核就是 4.9 的内核而且编译了 TCP BBR 的内容,所以可以直接通过参数开启。

新的 TCP 拥塞控制算法 BBR (Bottleneck Bandwidth and RTT) 可以让服务器的带宽尽量跑慢,并且尽量不要有排队的情况,让网络服务更佳稳定和高效。

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

保存生效

sysctl -p

执行

sysctl net.ipv4.tcp_available_congestion_control

如果结果是这样

"rootMF8-BIZ sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = bbr cubic reno

就开启了。

执行 lsmod | grep bbr ,以检测 BBR 是否开启。
