初始化

网络重装为debian9

使用moeclub.org的脚本

bash <(wget --no-check-certificate -qO- 'https://moeclub.org/attachment/LinuxShell/InstallNET.sh') -d 9 -v 64 -a

重装完成后修改root密码

开启BBR

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

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

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
