Oracle Free VPS Start BBR Acceleration Tutorial Based on Oracle Cloud centos7.7

Tutorial on applying for Oracle’s free VPS: https://www.138vps.com/freevps/1969.html

We are using Oracle's centos 7.7 version, because the kernel is already 4.14 and the system has built-in BRR, which only needs to be turned on. All this tutorial is very simple.

You can use the uname -r command to view the kernel. If your kernel is relatively low, please refer to this article to upgrade the kernel: https://www.138vps.com/vpsjc/971.html

In fact, the new version of centos kernel is relatively high and can be turned on directly.

Execute the following three commands:

echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf

echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf

sysctl-p

To observe whether BBR is opened successfully, execute the following code:

sysctl net.ipv4.tcp_available_congestion_control

sysctl net.ipv4.tcp_congestion_control

If the results all show bbr, it proves that your kernel has bbr enabled.
