After you logged in Web Gui, it will prompt you for recommended software packages, either LNMP or LAMP.

If there is any installation for LNMP not completed, you will need to install dependencies following the previous section's instruction. 

Eventually, you will have folloing packages installed. 

To install LNMP software, you might need some dependencies installed first.
For example, to Install LNMP (Nginx2.2.4 ，PHP 8.0， Mysql 5.7)

• yum install gcc build-essential
• yum install gcc gcc-c++ autoconf automake
• yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
  

If you got a message to say:
No match for argument: build-essential
Error: Unable to find a match: build-essential

We can try :

• yum install gcc gcc-c++ make

This works equivalent of build-essential in CentOS.

You might also need following package, Libiconv

• wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
• tar zxvf libiconv-1.13.1.tar.gz
• cd libiconv-1.13.1

Configure libiconv:

• ./configure -prefix=/usr/local --build arm-pc-linux

Compile and install:

• make
• make install

• ln -s /usr/local/lib/libiconv.so /usr/lib
• ln -s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2

If install Nginx 1.21 through aaPanel or BT panel, no matter using compiled method or fast method, you will meet Error: The HTTP image filter module requires the GD library, the easy fix is to install gd and gd-devel packages.

• yum install gd gd-devel

Google developed a TCP Congestion Control Algorithm (CCA) called TCP Bottleneck Bandwidth and RRT (BBR) that overcomes many of the issues found in both Reno and CUBIC (the default CCAs). This new algorithm not only achieves significant bandwidth improvements, but also lower latency. TCP BBR is already employed with google.com servers, and now you can make it happen--so long as your Linux machine is running kernel 4.9 or newer.

BBR is a new TCP congestion control algorithm that uses estimated congestion rather than loss to determine when to back off.

wget -N --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh && chmod +x bbr.sh && bash bbr.sh

Check if BBR has been installed and started:

sysctl net.ipv4.tcp_available_congestion_control
sysctl net.ipv4.tcp_congestion_control
sysctl net.core.default_qdisc
lsmod | grep bbr
ps -ef | grep bbr
