CentOS6.3 安裝 Python3.7.7 (快速註記)

本來測試安裝 Python3.8.2，但很3.8.2無法安裝 Pandas，因此退而求其次選擇 3.7.7 

由於未安裝compile工具，從此開始安裝

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 libffi-devel

*** 接著一定要記著先裝好 openssl ，否則 pip 不能用，又要重新 build

wget https://www.openssl.org/source/openssl-1.1.1e.tar.gz
tar -xzf openssl-1.1.1e.tar.gz
cd openssl-1.1.1e
./config --prefix=/usr/local/openssl no-zlib
make
make install

放置openssl  lib

mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl/ /usr/include/openssl.bak

ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl

echo /usr/local/lib >> /etc/ld.so.conf.d/openssl.conf


下載Python 及解壓縮

wget --no-check-certificate https://www.python.org/ftp/python/3.7.7/Python-3.7.7.tgz
tar -xzvf Python-3.7.7.tgz
cd Python-3.7.7

安裝。

./configure --with-openssl=/usr/local/openssl/
make
make install

安裝完畢，執行檔位於 /usr/local/bin 下面， python3 & pip3
