一、環境
1，系統：CentOS 7
2，用戶：root
3，Python版本：python3.6.8
二、安裝
1，登錄到centOS機器，新建文件夾
mkdir /usr/local/python3
2，將安裝包和依賴包里的文件上傳至/usr/local/python3
3，進入目錄
cd /usr/local/python3/
4，安裝依賴
#安裝依賴包 zlib-devel
rpm -ivh zlib-devel-1.2.7-17.el7.x86_64.rpm
#安裝依賴包 bzip2-devel
rpm -ivh bzip2-devel-1.0.6-13.el7.x86_64.rpm
#安裝依賴包 epel-release
rpm -ivh epel-release-7-11.noarch.rpm
#安裝依賴包 ncurses-devel
rpm -ivh ncurses-devel-5.9-13.20130511.el7.x86_64.rpm
# 安裝依賴包 gcc（一定要按照以下的順序進行安裝）
rpm -ivh mpfr-3.1.1-4.el7.x86_64.rpm
rpm -ivh libmpc-1.0.1-3.el7.x86_64.rpm
rpm -ivh kernel-headers-3.10.0-514.el7.x86_64.rpm
rpm -ivh glibc-headers-2.17-157.el7.x86_64.rpm
rpm -ivh glibc-devel-2.17-157.el7.x86_64.rpm
rpm -ivh cpp-4.8.5-11.el7.x86_64.rpm
rpm -ivh gcc-4.8.5-11.el7.x86_64.rpm
# 安裝依賴包 gcc-c+
rpm -ivh libstdc++-4.8.5-11.el7.x86_64.rpm
rpm -ivh libstdc++-devel-4.8.5-11.el7.x86_64.rpm
rpm -ivh gcc-c++-4.8.5-11.el7.x86_64.rpm
5，進行解壓
tar -xzvf Python-3.6.8.tgz
6，進入解壓路徑
cd /usr/local/python3/Python-3.6.8
7，設置安裝路徑
./configure --prefix=/usr/local/python3.6 --enable-shared
make
make install
ln -s /usr/local/python3.6/bin/python3 /usr/bin/python3
echo "/usr/local/python3.6/lib" > /etc/ld.so.conf.d/python3.6.conf
ldconfig
8，檢查Python3.6.8是否安裝成功
python3 -V
顯示如下圖，說明成功；
9，刪除安裝包以及依賴包
rm -rf /usr/local/python3
三、安裝pip3
1，python 3.6.8中自帶了pip，所以只需要建立鏈接就行
ln -s /usr/local/python3.6/bin/pip3.6 /usr/bin/pip3
2，檢查pip是否安裝成功
pip3 -V
出現如下圖，表示正常：
