In the process of using VPS, some users may want to install the BBR acceleration module. However, it is not possible to directly modify the system kernel settings in OpenVZ VPS. Fortunately, a developer on GitHub has created a modified version of the BBR module acceleration script, allowing us to enable BBR acceleration on OpenVZ VPS. The steps to deploy this script involve ensuring that the VPS is set up and ports are open, SSH into the VPS, and run the provided command to install the script. It is important to note that the script relies on the TUN module, so the VPS must have the TUN module enabled. The original GitHub repository for the script is provided for reference.

Preparation#

VPS with OpenVZ virtualization

Deployment Steps#

First, make sure that the node has been installed and the port is open.

SSH into the VPS and copy and paste the following command:

wget --no-cache -O lkl-haproxy.sh https://github.com/mzz2017/lkl-haproxy/raw/master/lkl-haproxy.sh && bash lkl-haproxy.sh

Enter y to confirm the installation.

Choose whether to accelerate a single port or a port range. I will choose a single port here.

Enter the acceleration port.

Wait for 1-3 minutes for the script installation to complete.

Notes#

Since the script depends on the TUN module, the VPS must have the TUN module enabled.
