Redhat7/centOs7 安装配置python3.6.5
centos默认安装python2，设置py2和py3并存的方法如下：
sudo yum install openssl-devel -y
sudo yum install zlib-devel -y
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
mkdir /usr/local/python3
tar -xvJf Python-3.6.5.tar.xz
cd Python-3.6.5
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
ln -f -s /usr/local/python3/bin/python3 /usr/bin/python
vi /usr/bin/yum 把#! /usr/bin/python修改为#! /usr/bin/python2
vi /usr/libexec/urlgrabber-ext-down 文件里面的#! /usr/bin/python 也要修改为#! /usr/bin/python2

(做上一步前先把 三个.so找到复制到/usr/loca/lib/
写入库文件所在目录 # vim /etc/ld.so.conf.d/usr-libs.conf /usr/local/lib
更新/etc/ld.so.cache文件 # ldconfig )
修改 /etc/profile 文件，在文件末尾加上如下两行代码 (把soapy_power.py放到目录下)
PATH=$PATH:/usr/local/..../bin
export PATH
