How to install Python 3.9 on Raspberry Pi

This short guide explains how to install Python version 3.9.0 on a Raspberry Pi running Raspbian.

First install the dependencies needed to build

sudo apt-get update
sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev

Compile (takes a while!)
wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tar.xz
tar xf Python-3.9.0.tar.xz
cd Python-3.9.0
./configure --prefix=/usr/local/opt/python-3.9.0
make -j 4

Install
sudo make altinstall

And remove the files

cd ..
sudo rm -r Python-3.9.0
rm Python-3.9.0.tar.xz
. ~/.bashrc

Make Python 3.9 the default version, make aliases
sudo update-alternatives --config python

And verify:
python -V

How-To Fedora 20 LAMP installation

This short guide demonstrates how to setup Fedora 20 as a LAMP server containing Apache, PHP, Perl, Python, Ruby and MySQL.

You have to use the shell and be able to use the machine as  root.

Start the terminal and run:

sudo yum install -y httpd php php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-magickwand php-mbstring php-mcrypt php-mssql php-shout php-snmp php-soap php-tidy php-mysql php-odbc php-pear php-mhash curl perl-libwww-perl ImageMagick libxml2 php-pecl-apc mysql mysql-server phpmyadmin ruby mod_python perl mod_perl perl-HTML-Parser perl-DBI perl-Net-DNS perl-Digest-SHA1 perl-ExtUtils-AutoInstall perl-NetAddr-IP perl-Archive-Tar

Second step is to enable the Apache Webserver and MySQL Database server;

sudo systemctl enable httpd.service sudo systemctl start httpd.service sudo systemctl enable mysqld.service sudo systemctl start mysqld.service sudo mysql_secure_installation

How-To setup Fedora Linux 15 as LAMP server

Aside

This short guide demonstrates how to setup Fedora 15 as a LAMP server containing Apache, PHP, Perl, Python, Ruby and MySQL.

You have to use the shell and be able to use the machine as  root.


sudo
yum install httpd
yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-eaccelerator php-magickwand php-magpierss php-mapserver php-mbstring php-mcrypt php-mhash php-mssql php-shout php-snmp php-soap php-tidy curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel
yum install mysql mysql-devel mysql-server
yum install httpd-devel ruby ruby-devel
yum install mod_python
yum install mod_perl
yum install perl-HTML-Parser perl-DBI perl-Net-DNS perl-Digest-SHA1 perl-ExtUtils-AutoInstall perl-NetAddr-IP perl-Archive-Tar
/etc/init.d/httpd restart

Now you have got everything installed except for mod_ruby – so that`s the next step;

cd /tmp
wget http://modruby.net/archive/mod_ruby-1.3.0.tar.gz
tar zxvf mod_ruby-1.3.0.tar.gz
cd mod_ruby-1.3.0/
./configure.rb --with-apr-includes=/usr/include/apr-1
make
make install
/etc/init.d/httpd restart

You have to add mod_ruby by hand in /etc/httpd/conf.d/ruby.conf
By adding

LoadModule ruby_module modules/mod_ruby.so
