搬瓦工openvz架构vps安装GOOGLE BBR 加速VPS

系统需求:

• CentOS 6 x64 (建议)
• 要求 glibc 版本 2.14 以上

更新 glibc {方法一}

CentOS 6 更新 glibc，首先下载如下几个文件：

wget http://ftp.redsleeve.org/pub/steam/glibc-2.15-60.el6.x86_64.rpm \
http://ftp.redsleeve.org/pub/steam/glibc-common-2.15-60.el6.x86_64.rpm \
http://ftp.redsleeve.org/pub/steam/glibc-devel-2.15-60.el6.x86_64.rpm \
http://ftp.redsleeve.org/pub/steam/glibc-headers-2.15-60.el6.x86_64.rpm \
http://ftp.redsleeve.org/pub/steam/nscd-2.15-60.el6.x86_64.rpm

然后安装：

# rpm -Uvh glibc-2.15-60.el6.x86_64.rpm \
glibc-common-2.15-60.el6.x86_64.rpm \
glibc-devel-2.15-60.el6.x86_64.rpm \
glibc-headers-2.15-60.el6.x86_64.rpm \
nscd-2.15-60.el6.x86_64.rpm

更新 glibc {方法二}:

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
../glibc-2.15/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make all && make install

检查一下：

# ldd --version
ldd (GNU libc) 2.15
Copyright (C) 2012 Free Software Foundation, Inc.

说明升级到 glibc 2.15 了.

安装google BBR脚本:

wget --no-check-certificate https://raw.githubusercontent.com/woyard/script/master/ovz-bbr/ovz-bbr-installer.sh
chmod +x ovz-bbr-installer.sh
./ovz-bbr-installer.sh

判断 BBR 已正常工作

判断 bbr 是否正常启动,可以在vps上尝试 ping 10.0.0.2，如果能通，说明 bbr 已经启动。

然后检查 iptables 规则:

iptables -t nat -nL
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
LKL_IN     all  --  0.0.0.0/0            0.0.0.0/0
 
Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination
 
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
 
Chain LKL_IN (1 references)
target     prot opt source               destination
DNAT       tcp  --  0.0.0.0/0            0.0.0.0/0            tcp dpt:8989 to:10.0.0.2

里边会看到多了一张链表 LKL_IN，里边有相应的端口规则。
