手把手从python安装到setuptools、pip工具安装

一、python安装
1、基础开发库

apt-get install gcc
apt-get install openssl libssl-dev

2、安装数据库和开发库

apt-get install mysql-server libmysqld-dev

3、python环境

下载地址：https://www.python.org/downloads/

tar -xvf Python-2.7.10.tar.xz

cd Python-2.7.10/

./configure --prefix=/opt/python2.7

make

make install

echo "export PATH=/opt/python2.7/bin:\$PATH" > /etc/profile.d/python.sh

echo $PATH

which python

mkdir ~/.python-eggs

chmod +w ~/.python-eggs

echo "export PATH=/opt/python2.7/bin:\$PATH" > /etc/profile.d/python.sh

export PATH=/opt/python2.7/bin:$PATH

二、setuptools安装
要使用easy_install工具，那么需要安装setuptools，方式如下：

下载地址：

https://pypi.python.org/pypi/setuptools

https://files.pythonhosted.org/packages/37/1b/b25507861991beeade31473868463dad0e58b1978c209de27384ae541b0b/setuptools-40.6.3.zip

方式如下：

unzip setuptools-28.8.0.zip

cd setuptools-28.8.0/

/opt/python2.7/bin/python ./setup.py install

四、pip安装
/opt/python2.7/bin/pip install -r ./requirements.txt

wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
python get-pip.py
