Ovz机器开启BBR加速(64bit only)

    由于刚刚接触这方面,也没有什么经验,自己买了一个垃圾而且超售的ovz机器,而且自带的linux内核版本并不支持开启bbr,所以打算分享一个前几天刚刚看到的ovz开启bbr的方法(暂时不清楚是否有加速效果),下面贴上原帖地址。

原帖地址查看 OpenVZ平台谷歌BBR加速TCP之Rinetd方式

    我再写一遍算是给自己备用吧!

首先将文件下载到/usr/bin/rinetd-bbr

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

给文件权限

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

新建配置文件

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

将其中的443改为你需要bbr加速的端口
在vim下按 i 进入输入模式,按 esc 进入命令模式,在命令模式下按 :wq 保存退出。

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

找到公网ip地址的接口
注意:示例上的接口应该是venet0:0而不是venet0

搬瓦工的OpenVZ应该都是venet0:0接口。
我的小鸡也是venet0:0。

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

Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            tcp dpt:443 /* LKL_RAW */
DROP       tcp  --  0.0.0.0/0            0.0.0.0/0            tcp dpt:443 /* LKL_RAW */

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

出现了如上所示两条规则了。
