python 版本升级

升级python

python  -V
Python 2.6.6

wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tgz[/code] 解压

tar -xvf Python-2.7.12.tgz

安装

cd Python-2.7.12
./configure --prefix=/usr/local/python2.7
make all
make install
make clean
make distclean

查看安装后python版本

/usr/local/bin/python2.7 -V
Python 2.7.12

建立软连接

mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/bin/python2.7 /usr/bin/python

重新检验Python 版本

python -V

解决系统 Python 软链接指向 Python2.7 版本后，因为yum是不兼容 Python 2.7的

vi /usr/bin/yum
# 修改 python 指向
#!/usr/bin/python  -> #!/usr/bin/python2.6.6
