Upgrade centos5.x to python2.7 and MySQL-Python

The Python version of centos5.3 is really tearful. When is it 2.4. Self-help clothes and food.

1. download version 2.7 from the official website

 

# Wget http://www.python.org/ftp/python/2.7.1/Python-2.7.1.tar.bz2

 

2. Installation

 

# Tar-jxvf Python-2.7.1.tar.bz2
# Cd Python-2.7.1
#./Configure (if -- prefix is not specified, it is installed in/usr/local/lib/python2.7 by default)
# Make & make install

 

3. Upgrade the default version

 

# Mv Python/usr/bin/python24
# Ln-S/usr/local/bin/python2.7/usr/bin/Python

 

4. Install mysql-Python

(For details about the installation method, see readme in the package)

# Python setup. py build
Traceback (most recent call last ):
File "setup. py", line 5, in <module>
From setuptools import setup, extension
Importerror: No module named setuptools

What is the situation? It seems that setuptools does not exist.

5. Go to the official website to download setuptools

Official Website

# Bash setuptools-0.6c11-py2.7.egg

Traceback (most recent call last ):

File "<string>", line 1, in <module>

Zipimport. zipimporterror: Can't decompress data; zlib not available

What is the situation? Zlib missing? (For the software environment required for installing python, see readme)

This step took me a long time to solve it, and the process was really unpleasant. From the above error message, it seems that zlib does not exist. The first thing that comes to mind is to use Yum to install zlib *.

# Rpm-Qa | grep zlib
Zlib-1.2.3-3
Zlib-devel-1.2.3-3

After re-compiling python, the system still prompts this error "zipimport. zipimporterror: Can't decompress data; zlib not available", which is a bit crazy at the end. When I was about to worry about browsing the official site of zlib, its latest version is zlib-1.2.5. I decided to use the tar package to install the latest version.

The installation process is very simple, but it is still three steps:

# Cd zlib-1.2.5
#./Configure

# Make & make install

In the process of solving this problem, I found the simplest "easy_install" in the python installation method, which will be used to install mysql-Python

# Wget http://peak.telecommunity.com/dist/ez_setup.py
# Python ez_setup.py

In the previous step, it installed the setuptools-0.6c11-py2.7.egg on its own so that you can use easy_install.

4. Install mysql-Python

The preceding error message indicates that the MySQL environment is not installed. MySQL needs to be installed. n characters are omitted here. After MySQL is installed, install mysql-Python again.

5. You have installed mysql-Python. Check the following:

# Python

Python 2.7.1 (r271: 86832, Apr 27 2011, 15:54:05)

It really hurts people. 99 steps have passed. Edit the lD. So. conf file and add the directory of libmysqlclient. so.16:

# Vi/etc/lD. So. conf

/Usr/local/innosql-5.5.8-linux-x86_64/lib/

# Ldconfig-V

 

Test again, Ko

Although the above installation process has no technical content, it is very annoying. I really hope that the uncles of the RedHat series will slightly upgrade their own Python version!
