1、CentOS安装Python的依赖包

yum groupinstall "Development Tools"

yum install zlib-devel bzip2-developenssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-develdb4-devel libpcap-devel xz-devel

2、下载Python3.5的源码包并编译

wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz/usr/local/src/

sudo mkdir /usr/tools/python

sudo tar xf /usr/local/src/Python-3.5.0.tgz-C /usr/tools/python/

cd /usr/tools/python/Python-3.5.0/

./configure--prefix=/usr/tools/python/python35

make -j8 && make install

3、覆盖原来的版本，并重新建立超链接

mv /usr/bin/python /usr/bin/python_old

ln -fs /usr/tools/python/python35/bin/python3.5/usr/bin/python

python --version

4、修改yum配置（否则yum无法正常运行）

vi /usr/bin/yum

将第一行的#!/usr/bin/python修改为系统原有的python版本地址#!/usr/bin/python2.6

5、删除编译Python时所需要的库

yum groupremove "Development Tools"

yum remove zlib-devel bzip2-developenssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-develdb4-devel libpcap-devel xz-devel

6、设置pip路径

vi /etc/profile

插入以下内容：

# set python-pip path

exportPYTHON_PIP_HOME=/usr/tools/python/python35

export PATH=$PATH:$PYTHON_PIP_HOME/bin

退出后调用：source /etc/profile
