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。
