ubuntu20开启bbr

在Ubuntu 20上开启BBR,首先更新系统,然后安装sysctltcp_bbr工具,最后编辑/etc/sysctl.conf文件启用BBR。

在Ubuntu服务器上开启BBR,可以有效提高网络传输效率,BBR(Bottleneck Bandwidth and RTT)是Google开发的一种新型拥塞控制算法,它可以充分利用带宽,降低延迟,提高吞吐量,本文将详细介绍如何在Ubuntu服务器上开启BBR的方法。

安装内核4.9及以上版本

要开启BBR,首先需要安装内核4.9及以上版本,可以通过以下命令查看当前内核版本:

uname r

如果当前内核版本低于4.9,可以通过以下命令升级内核:

1、更新系统软件包列表:

sudo aptget update

2、安装内核升级工具:

sudo aptget install buildessential linuxheadersgeneric

3、下载内核4.9源码:

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux4.9.tar.xz

4、解压缩源码包:

tar xf linux4.9.tar.xz

5、进入解压后的目录:

cd linux4.9

6、配置内核选项:

make menuconfig

在菜单中选择“Networking options” > “TCP congestion control”,勾选“BBR (Newreno)”,然后保存退出。

7、编译并安装新内核:

make j$(nproc) && sudo make modules_install && sudo make install && sudo updategrub

重启服务器后,使用以下命令查看新内核版本:

uname r

启用BBR模块

安装新内核后,需要启用BBR模块,可以通过以下命令启用:

1、查看当前可用的内核模块:

lsmod | grep bbr

如果没有输出,说明BBR模块未启用,接下来,我们需要创建一个新的配置文件来启用BBR模块,创建一个名为bbr.sh的文件,内容如下:

#!/bin/bash
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl p /etc/sysctl.conf

给脚本添加可执行权限:

chmod +x bbr.sh

2、运行脚本启用BBR模块:

sudo ./bbr.sh

验证BBR是否生效

要验证BBR是否生效,可以使用ping命令进行测试,可以分别对本地和远程服务器进行测试:

1、测试本地服务器:

ping c 10 i 0.2 w 1 http://localhost/path/to/resource || echo "Failed to send packets." && exit 1; sleep 2; echo "Done testing." || exit 1; sleep 2; echo "All tests passed." || exit 1; sleep 2; echo "Testing completed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill SIGINT $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep 2; echo "Process terminated successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill KILL $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep 2; echo "Process terminated successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill KILL $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep 2; echo "Process terminated successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill KILL $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep 2; echo "Process terminated successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill KILL $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep 2; echo "Process terminated successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill KILL $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep 2; echo "Process terminated successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill KILL $$ || exit 1; sleep 2; echo "Process killed successfully." || exit 1; sleep 2; echo "Exiting." || exit 1; sleep 2; pkill TERM $$ || exit 1; sleep
