BBR original version/BBR magic modification/BBR Plus + Ruisu and other four-in-one installation scripts

This script combines the original BBR, modified BBR, BBR Plus and Ruisu. You can use whichever one you want. I can only say: it is so convenient!

Tested on Centos 7, Debian 8/9, Ubuntu 16/18 on Vultr. OVZ and LXC are not supported.

It is recommended to use SSH as the root user.

1. Install the certificate
apt-get -y install ca-certificates
or
yum -y install ca-certificates

2. Installation
wget "https://github.com/chiakge/Linux-NetSpeed/raw/master/tcp.sh" && chmod +x tcp.sh && ./tcp.sh
1. Switch the kernel in [1 – 3] (if it is displayed as bbr kernel for the first time, you need to switch it again), and restart

This option appears

2. After restarting, you don’t need to download the script again. Just run ./tcp.sh and select the acceleration you want to enable in [4 – 8]

"1. Install BBR/BBR modified kernel" corresponds to 4, 5, 6 (original, modified, violent modified)
"2. Install the BBRplus kernel" corresponds to 7 (plus)
"3. Install the Lotserver (Ruisu) kernel" corresponds to 8 (Ruisu)

3. After enabling, run ./tcp.sh again. If it shows that it is enabled successfully, then the startup is successful. You can also confirm it manually

Now you can freely switch the acceleration you want until you don't want to toss it~
