写在前面
centos6.8中默认自带的python版本为python2.6，那么这里需要将其改为python3
下载并解压
官方下载地址为 https://www.python.org/downlo... ，这里已3.6.3为例。
# 下载
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
# 解压
tar -zxvf Python-3.6.3.tgz
cd Python-3.6.3安装
[root@localhost ~]# ./configure prefix=/usr/local/python3 --enable-optimizations
[root@localhost ~]# make && make install 修改python3为默认的python
[root@localhost ~]# which python
/usr/bin/python
[root@localhost ~]# mv /usr/bin/python /usr/bin/python.bak
/usr/bin/python
[root@localhost ~]# ln -s /usr/local/python3/bin/python3 /usr/bin/python
python3和python2共存
[root@localhost ~]# python -V
Python 3.6.3
[root@localhost ~]# python2.6 -V
Python 2.6.6
由于yum用的python仍然是2.6，所以这里修改一下
[root@localhost ~]# vim /usr/bin/yum将第一行改为：
#!/usr/bin/python2.6原文地址：http://www.tech1024.com/origi...
