# 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
|
||||
