OpenVZ平台开启Google BBR

  • 使用的系统是CentOS 6 x64

     wget https://raw.githubusercontent.com/kuoruan/shell-scripts/master/ovz-bbr/ovz-bbr-installer.sh
      chmod +x ovz-bbr-installer.sh
      ./ovz-bbr-installer.sh
    
  • 会进行安装ovz-bbr但是由于cs6的 glibc 版本 是2.12,这里需要升级 glibc大于2.12.

  • CentOS 6 更新 glibc,首先下载如下几个文件:

wget http://ftp.gnu.org/gnu/glibc/glibc-2.15.tar.gz
wget http://ftp.gnu.org/gnu/glibc/glibc-ports-2.15.tar.gz
tar -zxf glibc-2.15.tar.gz
tar -zxf glibc-ports-2.15.tar.gz
mv glibc-ports-2.15 glibc-2.15/ports
mkdir glibc-build-2.15
cd glibc-build-2.15
yum install gcc
../glibc-2.15/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make all && make install
  • ldd --version查看当前的glibc的版本

      ldd (GNU libc) 2.15

  • 然后后退到根目录下执行
    ./ovz-bbr-installer.sh

  • 选择需要加速的端口即可开启

  • 判断 BBR 已正常工作

       ping 10.0.0.2,如果能通,说明 bbr 已经启动。
