suse11 sp4自带zlib-1.2.7但是make & make install时提示你找不到zlib.h
所以安装zlib-1.2.8即可
tar -xvf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make & make install
第二步：安装python3.6.5
进入到下载后的python文件目录下
./configure --prefix=/usr/local/python3
make & make install
（备注：--prefix=/usr/local/python/python3.6.5 指的是安装后的路径，自己随便指向）
第三步：创建指向（这样做可以在不破化系统使用的到的python2.6.9）
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
测试：
cd /usr/bin/
python3
==运行结果==
Python 3.6.5 (default, Apr 3 2018, 11:25:01)
