• 使用的系統(tǒng)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
  

• 會進(jìn)行安裝ovz-bbr但是由于cs6的 glibc 版本 是2.12，這里需要升級 glibc大于2.12.

• CentOS 6 更新 glibc，首先下載如下幾個文件：

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查看當(dāng)前的glibc的版本

    ldd (GNU libc) 2.15

• 然后后退到根目錄下執(zhí)行
  ./ovz-bbr-installer.sh

• 選擇需要加速的端口即可開啟

• 判斷 BBR 已正常工作

     ping 10.0.0.2，如果能通，說明 bbr 已經(jīng)啟動。
