CentOS7 开启 BBR

CentOS7 是一种广泛使用的开源操作系统BBR 又称为拥塞控制算法。BBR 采用了一种类似于 TCP 客户端的拥塞控制策略。这种策略可以帮助优化网络连接并提高网络传输速度。

如何安装 BBR

在 CentOS7 中安装 BBR 非常容易。首先请确保你已经连接到服务器然后打开终端窗口。然后输入以下命令以安装 BBR:

sudo yum -y install kmod-tcp-bbr

如果在安装过程中出现错误请检查你是否已启用 EPEL 存储库。如果没有启用请使用以下命令启用它:

sudo yum -y install epel-release

一旦安装完成你需要修改系统配置文件以便正确启用 BBR。请使用以下命令打开配置文件:

sudo vi /etc/sysctl.conf

然后将以下内容添加到文件底部:

net.core.default_qdisc=fq

net.ipv4.tcp_congestion_control=bbr

如何检查 BBR 是否已启用

在安装和配置 BBR 之后你应该检查系统是否已正确启用 BBR。请使用以下命令检查:

sudo sysctl net.ipv4.tcp_congestion_control

如果控制台返回以下内容则表示 BBK 已启用:

net.ipv4.tcp_congestion_control = bbr

结论

在本文中我们简要介绍了 CentOS7 操作系统和 BBR 拥塞控制算法。我们还提供了一些关于如何安装和配置 BBR 的步骤。如果你要使用 CentOS7 并想要最大程度地优化你的网络连接那么我们强烈建议你安装和启用 BBR。它将帮助加快你的网络传输速度提高硬件性能使你的互联网体验更加高效和快速。

Enable BBR on CentOS7

CentOS7 is a widely used open-source operating system and BBR (Bottleneck Bandwidth and Round-trip propagation time) is a new congestion control algorithm. BBR uses a congestion control strategy similar to TCP clients, that helps optimize network connections and improve network transmission speeds.

How to Install BBR

Installing BBR on CentOS7 is straightforward. First, make sure you are connected to the server, and then open a terminal window. Then, enter the following command to install BBR:

sudo yum -y install kmod-tcp-bbr

If there are errors during the installation process, check whether you have enabled the EPEL repository. If not, enable it with the following command:

sudo yum -y install epel-release

Once installed, you need to modify the system configuration file to enable BBR correctly. Open the configuration file with the following command:

sudo vi /etc/sysctl.conf

Then, add the following content to the bottom of the file:

net.core.default_qdisc=fq

net.ipv4.tcp_congestion_control=bbr

How to Check if BBR is Enabled

After installing and configuring BBR, you should check whether the system has enabled BBR correctly. Use the following command to check:

sudo sysctl net.ipv4.tcp_congestion_control

If the console returns the following content, it means that BBR is enabled:

net.ipv4.tcp_congestion_control = bbr

Conclusion

In this article, we briefly introduced the CentOS7 operating system and the BBR congestion control algorithm. We also provided some steps on how to install and configure BBR. If you are using CentOS7 and want to optimize your network connection to the fullest, we highly recommend installing and enabling BBR. It will help speed up your network transmission, improve hardware performance, and make your internet experience more efficient and speedy.
