# BBRplus
|
||||
|
||||
## 脚本安装方法:
|
||||
|
||||
一键脚本(全系统):
|
||||
参见https://github.com/chiakge/Linux-NetSpeed
|
||||
|
||||
一键脚本(仅CentOS):
|
||||
```bash
|
||||
wget --no-check-certificate https://raw.githubusercontent.com/Yuk1n0/Shadowsocks-Install/master/bbrplus_centos.sh && chmod +x bbrplus_centos.sh && ./bbrplus_centos.sh
|
||||
```
|
||||
安装后,执行uname -r,显示4.14.129-bbrplus则切换内核成功
|
||||
执行lsmod | grep bbr,显示有bbrplus则开启成功
|
||||
|
||||
## 手动安装方法:
|
||||
1. 卸载本机的锐速(如果有)
|
||||
|
||||
2. 下载内核
|
||||
wget --no-check-certificate https://github.com/Yuk1n0/Shadowsocks-Install/raw/master/Centos7/x86_64/kernel-4.14.129-bbrplus.rpm
|
||||
|
||||
3. 安装内核
|
||||
yum install -y kernel-4.14.129-bbrplus.rpm
|
||||
|
||||
4. 切换启动内核
|
||||
grub2-set-default 'CentOS Linux (4.14.129-bbrplus) 7 (Core)'
|
||||
|
||||
5. 设置fq
|
||||
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
|
||||
设置bbrplus
|
||||
echo "net.ipv4.tcp_congestion_control=bbrplus" >> /etc/sysctl.conf
|
||||
|
||||
6. 重启
|
||||
reboot
|
||||
|
||||
7. 检查内核版本 uname -r
|
||||
显示4.14.129-bbrplus则成功
|
||||
|
||||
8. 检查bbrplus是否已经启动
|
||||
lsmod | grep bbrplus 显示有tcp_bbrplus则成功
|
||||
|
||||
## 卸载方法:
|
||||
安装别的内核bbrplus自动失效,卸载内核自行谷歌即可
|
||||
|
||||
## 内核编译:
|
||||
|
||||
只能用于4.14.x内核,更高版本的tcp部分源码有改动,要移植到高版本内核得自己研究
|
||||
|
||||
下载4.14内核源码
|
||||
wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.91.tar.xz
|
||||
|
||||
解压
|
||||
tar -Jxvf linux-4.14.91.tar.xz -C /root/
|
||||
|
||||
修改linux-4.14.91/include/net/inet_connection_sock.h,139行
|
||||
u64 icsk_ca_priv[112 / sizeof(u64)];
|
||||
#define ICSK_CA_PRIV_SIZE (14 * sizeof(u64))
|
||||
这两段数值改为112和14,如上
|
||||
|
||||
修改/net/ipv4/tcp_output.c#L,1823行
|
||||
tcp_snd_wnd_test函数大括号后}
|
||||
换行添加EXPORT_SYMBOL(tcp_snd_wnd_test);
|
||||
|
||||
添加tcp_bbrplus.c,删除/net/ipv4/tcp_bbr.c
|
||||
修改linux-4.14.91/net/ipv4/Makefile,
|
||||
obj-$(CONFIG_TCP_CONG_BBR) += tcp_bbrplus.o,bbr改为bbrplus
|
||||
|
||||
安装依赖
|
||||
**Centos**
|
||||
yum -y groupinstall Development tools
|
||||
yum -y install ncurses-devel bc gcc gcc-c++ ncurses ncurses-devel cmake elfutils-libelf-devel openssl-devel rpm-build redhat-rpm-config asciidoc hmaccalc perl-ExtUtils-Embed xmlto audit-libs-devel binutils-devel elfutils-devel elfutils-libelf-devel newt-devel python-devel zlib-devel
|
||||
|
||||
**Debian**
|
||||
wget -qO- git.io/superupdate.sh | bash
|
||||
apt-get install build-essential libncurses5-dev
|
||||
apt-get build-dep linux
|
||||
|
||||
切换到目录
|
||||
cd /root/linux-4.14.91
|
||||
|
||||
配置
|
||||
make oldconfig
|
||||
或者
|
||||
make menuconfig
|
||||
|
||||
确保CONFIG_TCP_CONG_BBR=m
|
||||
|
||||
禁用签名调试
|
||||
scripts/config --disable MODULE_SIG
|
||||
scripts/config --disable DEBUG_INFO
|
||||
|
||||
