1.安裝openssl靜態庫【pip3安裝需要，如果已經安裝請跳過】

yum install -y openssl-static

2.安裝GCC和wget【如果已經安裝請跳過】

yum install -y gcc wget

yum groupinstall "Development tools"

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

3.下載python3的源碼包
wget http://python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz

4.加壓源碼包
tar xf Python-3.6.1.tar.xz

5.設定安裝路徑
cd Python-3.6.1
./configure --prefix=/usr/local/python3

6.編譯安裝包並安裝
make
make install

7.添加檔案連結，因為我們自訂了安裝路徑
ln -s /usr/local/python3/bin/python3 /usr/bin/python3

8.檢驗是否安裝成功，出現以下介面說明成功了
python3 -V

9.配置pip3捷徑

ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
