1. 安裝依賴環境python
# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-develsql
2. 瀏覽器打開 https://www.python.org/ftp/python/ 查看最新的Python版本,標記爲3.A.B瀏覽器
# wget https://www.python.org/ftp/python/3.A.B/Python-3.A.B.tgz測試
3. 建立Python3的目錄sqlite
# mkdir /usr/local/python3ip
4. 解壓下載文件並切換目錄ssl
# tar -zxvf Python-3.A.B.tgzget
# cd Python-3.A.Bopenssl
5. 執行it
# ./configure --prefix=/usr/local/python3
# make && make install
6. 建立Python3的軟連接
# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
7. 建立Pip3的軟連接
# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
8. 測試命令 python3 和 pip3
# python3
# pip3
安裝保留了原python命令調用python2
