You need to install Zlib,setuptools before installing PIP

• Installing zlib

#yum-y install zlib error, as follows:

No module named Yum

650) this.width=650; "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ("/e/u261/lang /zh-cn/images/localimage.png ") no-repeat center;border:1px solid #ddd;" alt= "Spacer.gif"/>

The reason for this error is that I upgraded Python, which makes Yum unusable.

Reference Documentation: http://blog.csdn.net/ei__nino/article/details/8495295

Workaround:

# Vi/usr/bin/yum

#!/usr/bin/python_old

//The first line of the file changed to #!/usr/bin/python_old because I renamed the old Python python_old. and Yum matches the old Python.

#/sbin/service yum-updatesd Restart

# yum-y Install zlib zlib-devel //Installation Successful! But installation Setuptools still error. Need to recompile python.

Recompile python below

# cd/usr/local/python-2.7.10

#./configure--prefix=/usr/local/python2.7

#make && make Install

• Installing Setuptools

#cd/usr/local

# Curl-o Https://pypi.python.org/packages/source/s/setuptools/setuptools-2.0.tar.gz

# tar ZXVF setuptools-2.0.tar.gz

# CD setuptools-2.0

#python setup.py Build

#python setup.py Install//Success

• Install PIP

PIP official website Https://pypi.python.org/pypi/pip

#cd/usr/local

# Curl-o https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz#md5=3823d2343d9f3aaab21cf9c917

# Curl-o https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz

Use wget download will error, here instead of Curl-o can, these 2 commands download the package is right

# tar ZXVF pip-7.1.2.tar.gz
# CD pip-7.1.2
#python setup.py Install

# ln-s/usr/local/python2.7/bin/pip/usr/bin/pip

The //pip is installed by default under/usr/local/python2.7/bin/

#pip // test PIP

Error: Importerror:cannot Import name Httpshandler

The reason is that openssl,openssl-devel two packages are not installed correctly

Workaround:

#Yum install OpenSSL openssl-devel-y

Continue to error, then I recompile Python and Pip. OK no longer has an error.
