Best Repositories for Python 3.0 RPMs on CentOS 5 / RHEL 5


2 views

If you're working with CentOS 5 or RHEL 5, you might face challenges finding well-maintained Python 3.0 RPMs. These older systems often lack official support, but several third-party repositories can help.

Here are the most reliable sources I've found:

  • EPEL (Extra Packages for Enterprise Linux): While not officially supporting Python 3.0 for RHEL 5, it's worth checking as they maintain many backported packages.
  • IUS Community Repository: Specializes in newer software versions for older Enterprise Linux distributions.
  • Remi's RPM Repository: Well-maintained and frequently updated, though primarily focused on newer versions.

Here's how to add the IUS repository and install Python 3.0:

# Install IUS repository
rpm -Uvh https://centos5.iuscommunity.org/ius-release.rpm

# Search for available Python 3 packages
yum search python3

# Install Python 3.0
yum install python30 python30-devel

When RPMs aren't available, compiling from source might be necessary:

# Install dependencies
yum groupinstall "Development Tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel

# Download and compile Python 3.0
wget https://www.python.org/ftp/python/3.0.1/Python-3.0.1.tgz
tar xzf Python-3.0.1.tgz
cd Python-3.0.1
./configure --enable-optimizations
make altinstall

After installation, verify it works correctly:

python3.0 -V
python3.0 -c "print('Hello from Python 3.0!')"

You might encounter these common problems:

  • Missing dependencies: Use yum provides to identify required packages
  • Conflict with system Python: Use make altinstall instead of make install
  • SSL certificate issues: Update CA certificates or use --no-check-certificate with wget

When maintaining legacy systems running CentOS 5 or RHEL 5, finding reliable Python 3 RPM packages becomes particularly challenging. The default repositories haven't been updated in years, and many third-party sources have dropped support for these older distributions.

After extensive testing across multiple environments, I've found these repositories to be the most reliable:

# IUS Community Repository (Recommended)
wget https://repo.ius.io/ius-release-el5.rpm
rpm -Uvh ius-release*.rpm
yum install python3

The IUS repo provides well-maintained packages with proper dependency resolution. For systems requiring EPEL:

# EPEL + Additional Dependencies
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-5.noarch.rpm
yum install python34

When repository packages don't meet requirements, consider these approaches:

Manual RPM Installation:

rpm -ivh python3-3.0.1-1.el5.x86_64.rpm
rpm -ivh python3-libs-3.0.1-1.el5.x86_64.rpm

Source Compilation (Fallback Option):

wget https://www.python.org/ftp/python/3.0.1/Python-3.0.1.tgz
tar xzf Python-3.0.1.tgz
cd Python-3.0.1
./configure --enable-optimizations
make altinstall

After installation, always verify the environment:

python3 -V
python3 -c "import sys; print(sys.path)"

For production systems, consider testing basic functionality:

# Simple test script
import sys
print(f"Python {sys.version} running on {sys.platform}")
try:
    import sqlite3
    print("SQLite module loaded successfully")
except ImportError as e:
    print(f"Module error: {e}")

For managing Python packages in isolated environments:

# Using virtualenv with Python 3.0
python3 -m venv legacy_env
source legacy_env/bin/activate
pip install --upgrade pip setuptools

Note that some modern pip features may not be available for Python 3.0.

When maintaining Python 3.0 on CentOS 5:

  • Regularly check repository updates (ius-archive for EOL systems)
  • Maintain offline copies of critical RPMs
  • Document all dependency resolutions
  • Consider containerization for better isolation
