    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
