環境準備

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

首先去官網下載python3.6

https://www.python.org/ftp/python/

這裡我們下載

yum -y install wget  # 安裝wget
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz

建立python3.6目錄

mkdir /usr/local/python3.6

解壓python3.6安裝包

tar -xzvf Python-3.6.8.tgz

進入解壓路徑

cd Python-3.6.8

原始碼安裝三個步驟

# 配置(configure)
./configure --prefix=/usr/local/python3.6 --enable-optimizations

# 編譯(make)
make

# 安裝(make install)
makeinstall

建立軟連線

ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3.6

ln -s /usr/local/python3/bin/pip /usr/bin/pip3.6

加入環境變數

在etc/profile最後一行中加入變數

export PATH="$PATH:/usr/local/python3.6/bin"

檢測是否安裝成功

python3.6    # 進入python3.6

pip3.6 -V    # 顯示pip的版本
