qq6825995

以前buyvm 安装bbr都没有问题,昨天买的就出现问题了,采用秋水大佬的脚本

系统centos7

错误代码:

rpm -ivh kernel-ml-5.15.60-1.el7.x86_64.rpm
error: Failed dependencies:
        linux-firmware >= 20100806-2 is needed by kernel-ml-5.15.60-1.el7.x86_64
[Error] Execution command (rpm -ivh kernel-ml-5.15.60-1.el7.x86_64.rpm) failed, please check it and try again.

已经解决
参考秋水大佬https://teddysun.com/648.html  手工开启
下载安装内核,我这里是最新的(centos7),其他版本请到https://dl.lamp.sh/kernel/el7/
wget https://dl.lamp.sh/kernel/el7/kernel-ml-6.2.13-1.el7.x86_64.rpm

wget https://dl.lamp.sh/kernel/el7/kernel-ml-devel-6.2.13-1.el7.x86_64.rpm

wget https://dl.lamp.sh/kernel/el7/kernel-ml-headers-6.2.13-1.el7.x86_64.rpm
安装内核
yum localinstall kernel-ml-*
查看本机已经存在的内核列表
awk -F\' '$1=="menuentry " {print i++ " : " $2}' /boot/grub2/grub.cfg
设置启动最新内核
grub2-set-default 1  (我的是1)

删除 rpm 文件
rm -fv kernel-ml-*
重启
reboot
开启bbr,依次执行以下每行命令
echo 'net.core.default_qdisc=fq' | tee -a /etc/sysctl.conf
echo 'net.ipv4.tcp_congestion_control=bbr' | tee -a /etc/sysctl.conf
sysctl -p
进行BBR的启用验证
sysctl net.ipv4.tcp_available_congestion_control
sysctl -n net.ipv4.tcp_congestion_control
最后检查BBR模块是否已经加载
lsmod | grep bbr

至此，BBR的部署已全部完成
