python2.7更新至3.6 - 小记一下

python源 https://www.python.org/ftp/python/

 更新至其余版本替换源路径及相应文件版本即可

 752 wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
 753 pwd
 754 ls
 755 tar -zxvf Python-3.6.0.tgz 
 756 ls
 757 cd ./Python-3.6.0
 758 ./configure 
 759 make 
 760 make install
 761 python --version
 762 python -V
 763 python3 -V
 764 ls -al /usr/bin | grep python
 765 mv /usr/bin/python /usr/bin/python.bak
 766 ln -s /usr/local/bin/python3 /usr/bin/python
 767 python -V
 768 vi /usr/bin/yum
 769 vi /usr/libexec/urlgrabber-ext-down
 770 history

vi两步 打开后将 #!/usr/bin/python 改为 #!/usr/bin/python2.7 保存退出即可。
