linux下安装python3.5.3

安装python3.5可能使用的依赖

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

到python官网找到下载路径, 用wget下载

wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz

解压tgz包

tar -zxvf Python-3.5.3.tgz

把python移到/usr/local下面

mv Python-3.5.3 /usr/local

删除旧版本的python依赖

ll /usr/bin | grep python
rm -rf /usr/bin/python

进入python目录

cd /usr/local/Python-3.5.3/

配置

./configure

编译 make

make

编译，安装

make install

删除旧的软链接，创建新的软链接到最新的python

rm -rf /usr/bin/python

ln -s /usr/local/bin/python3.5 /usr/bin/python

python -V

升级python后如出现yum 安装报错 File "/usr/bin/yum", line 30 except KeyboardInterrupt, e:因为yum包使用python2*等开发，修该为环境修改python3之后有问题，
解决：
修改文件/usr/bin/yum、/usr/libexec/urlgrabber-ext-down头中相应python为#!/usr/bin/python2.7
