OpenVZ平台Google BBR加速TCP之Rinetd方式

简介

Rinetd这种方式其实两三个月前就已经有了，是v2ex网友@linhua的成果，他直接将BBR内置到了Rinetd里边，比较方便的就能配置出来。也就是由于配置比较简单，先说一下手动搭建的方法。后续扩软博主可能会制作出通用的rinetd-bbr一键脚本，到时候更新一键包方法。

手动安装

Github地址：https://github.com/linhua55/lkl_study
系统支持：仅支持64位系统。
1、下载文件到/usr/bin/rinetd-bbr

wget -O /usr/bin/rinetd-bbr https://github.com/linhua55/lkl_study/releases/download/v1.2/rinetd_bbr_powered

2、设置权限

chmod a+x /usr/bin/rinetd-bbr

3、创建配置文件

vi /etc/rinetd-bbr.conf

输入以下内容

# bindadress bindport connectaddress connectport
 
0.0.0.0 443 0.0.0.0 443

其中的443请改为你的端口，IP地址统一写0.0.0.0。

4、获取接口名称

# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
    link/void
    inet 127.0.0.2/32 scope host venet0
    inet 10.10.10.10/32 brd 10.10.10.10 scope global venet0:0

看具有公网IP的接口名称（比如我的公网IP是10.10.10.10），上面这种的接口是venet0:0而不是venet0，搬瓦工的OpenVZ应该都是venet0:0接口。

5、启动

/usr/bin/rinetd-bbr -f -c /etc/rinetd-bbr.conf raw venet0:0 &

注意：将最后的接口改为你上面获取到的接口。在命令最后面加&以使其能后台运行。

查看iptables规则：

# iptables -t raw -nL

已经有两条规则了。
