BBR+BBR Magic Modification+Lotsever (Sharp Speed) One-Click Script for Centos/Debian/Ubuntu

Note: For the CentOS system's BBR modification, I previously carried over the script from the great master Nanqinlang, but unfortunately, a BUG occurred, leading to issues with the CentOS installation. A few days ago, the blogger Qianying, who is a friend link, also wrote a modified BBR script. This script includes BBR + BBR modified version + Lotsever (锐速), and supports CentOS, Debian, and Ubuntu systems, making it very convenient and powerful.

Tutorial Update#

【December 24, 2018】
The script has added a revised version of BBRplus, solving the issues of the original BBR being prone to speed loss under high packet loss rates and slow convergence. It attempts to improve performance, reducing queuing and packet loss.
【March 8, 2018】
The script has added Nanqinlang's violent modified BBR, making the speed more aggressive, with actual effects depending on the line.

Script Installation#

Supported Systems: CentOS 6+, Debian 8+, Ubuntu 14+.

Note: If the server has important data, it is recommended to back up the data before installation, especially for the CentOS system.

Run the following command:

# The process has 2 steps, the first step is to install the corresponding kernel, the second step is to enable the corresponding acceleration for the kernel
wget -N --no-check-certificate "https://raw.githubusercontent.com/chiakge/Linux-NetSpeed/master/tcp.sh" && chmod +x tcp.sh && ./tcp.sh

After using the script, the following options will appear:

Operate according to your needs, and after restarting, use the ./tcp.sh command to continue.

If a picture like this appears during the kernel deletion phase,

be sure to select NO, and then restart the system according to the prompt.

Finally, due to the integration of too many accelerations in this script, compatibility may not be very good, and for some systems, the installation of BBR may not be successful.

In terms of speed improvement, the effect of Ruisu is the best. The modified BBR and the revised version of BBR have varying test effects due to different VPS networks, so it's best to test the specific effects yourself before making a choice.
