centos6.x​之python2.6升级为2.7

centos6.x开始升级为2.7 :

yum -y install gcc zlib zlib-devel python-devel libffi-devel openssl openssl-devel 
wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz   
tar -xvf Python-2.7.14.tgz  
cd Python-2.7.14
./configure --prefix=/opt/python2.7 --with-ssl 
make && make install

mv /usr/bin/python /usr/bin/python.2.6
rm -f /usr/bin/python-config
ln -s /opt/python2.7/bin/python /usr/bin/python
ln -s /opt/python2.7/bin/python-config /usr/bin/python-config
ln -s /opt/python2.7/include/python2.7/ /usr/include/python2.7 

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
ln -s /opt/python2.7/bin/pip2.7 /usr/bin/pip2.7
sed -i "s/bin\/python/bin\/python2.6/g" /usr/bin/yum
ln -s /opt/python2.7/bin/easy_install /usr/bin/easy_install

注: 不要忘记修改yum 值否则会报什么module 的错误 

        vim /usr/bin/yum

        #!/usr/bin/python2.6 

注意使用 pip2.7 而不是pip 执行

其它问题:

错误1: 

  File "setup_posix.py", line 25, in mysql_config

        raise EnvironmentError("%s not found" % (mysql_config.path,))

    EnvironmentError: mysql_config not found 

解决方法: ln -s /opt/mysql/bin/mysql_config /usr/bin/mysql_config 

pip2.7 install MySQL-python
