cd pip-1.5.5/
python setup.py install
python2.7.5升级到3.6.4
yum install -y gcc* openssl openssl-devel ncurses-devel.x86_64 bzip2-devel sqlite-devel zlib python-devel mysql-devel openldap-devel
wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tar.xz

cd Python-3.6.4
mkdir -p /usr/local/python3
./configure --prefix=/usr/local/python3
make && make install
mv /usr/bin/python /usr/bin/python2.7.5
mv /usr/bin/pip /usr/bin/pip2.7
ln -s /usr/local/python3/bin/python3 /usr/bin/python
ln -s /usr/local/python3/bin/pip3.6 /usr/bin/pip
查看版本
[[email protected] Python-3.6.4]# pip -V
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)
[[email protected] Python-3.6.4]# python -V
Python 3.6.4
[[email protected] Python-3.6.4]# which python

vim /usr/bin/yum
vim /usr/libexec/urlgrabber-ext-down

PS:python3.6.4是默认安装pip的,所以不需要另行安装setuptools和pip.
