Linux升级python3.x安装pip

网上的教程比较混杂，而且讲真的都很有问题，下面我这套是我独家升级方法。这种方法不需要安装setuptools pip 因为编译的时候就会编译好，yum也可以正常使用。

yum install epel-release openssl-devel zlib-devel zlib gcc gcc-c++
tar -zxf Python-3.5.2.tgz
cd Python-3.5.2/
./configure --prefix=/usr/local/python
make && make install

[root@localhost ~]# mv /usr/bin/python python.backup
[root@localhost bin]# ln -s /usr/local/python/bin/python3.5 /usr/bin/python
[root@localhost bin]# ln -s /usr/local/python/bin/pip3 /usr/bin/pip

[root@localhost bin]# vi /usr/bin/yum
[root@localhost bin]# vi /usr/libexec/urlgrabber-ext-down
