1、將Python3.6.5安裝包及python36_install.sh放在同一目錄

# ll -thr-rw-r--r--.  1 root root   22M Aug 10 05:09 Python-3.6.5.tgz
-rw-r--r--.  1 root root  1.2K Aug 10 20:58 python36_install.sh
-rw-r--r--.  1 root root   71K Aug 28 04:50 redis-3.5.3-py2.py3-none-any.whl

安裝指令碼內容

# vim python36_install.sh
#!/bin/bash
#===============================================================================
 
# 
# FILE: python36_install.sh
#
# USAGE: install python36 script
#

tar -vxf Python-3.6.5.tgz 
 
if [[ $? = 0 ]];then
    echo ''
    echo -e "\e[1;32mpython3.6 unzip success.\e[0m"
    cd Python-3.6.5
    yum install gcc openssl openssl-devel ncurses-devel.x86_64  bzip2-devel sqlite-devel python-devel zlib -y
    if [[ $? = 0 ]];then
        echo -e "\e[1;32myum install success.\e[0m"
        ./configure --prefix=/usr/local/python3
        
 
if [[ $? = 0 ]];then
            echo -e "\e[1;32mpython configure success.\e[0m"
            make
            if [[ $? = 0 ]];then
                echo -e "\e[1;32mpython make success.\e[0m"
                make install
                if [[ $? = 0 ]];then
                    echo -e "\e[1;32mpython make install success.\e[0m"
                    ln -sv /usr/local/python3/bin/python3 /usr/bin/python3
                    ln -sv /usr/local/python3/bin/pip3 /usr/bin/pip3
                    echo -e "\e[1;32mpython3.6 install success.\e[0m"
                    python3
                else
                    echo -e "\e[1;31mpython3.6 make install failed.\e[0m"
                    exit
                fi
            else
                echo -e "\e[1;31mpython make failed.\e[0m"
                exit
            fi
        else
            echo -e "\e[1;31mpython configure failed.\e[0m"
            exit
        fi
    else
        echo -e "\e[1;31m2yum install failed.\e[0m"
        exit
    fi    
else
    echo ''
    echo -e "\e[1;31mpython3.6 unzip failed.\e[0m"
    exit
fi

2、執行指令碼

sh python36_install.sh

3、會自動安裝好Python和pip，並做成軟連結，與現有Python不衝突

4、離線安裝pip包

有的生產系統伺服器不允許連線內網，所以要用離線方法安裝

先在能上網伺服器下載

pip3 install redis --download /tmp

# 下載後的檔案以whl字尾的檔案，在/tmp目錄
-rw-r--r-- 1 root root 71K 8月 28 16:30 redis-3.5.3-py2.py3-none-any.whl

將檔案拷貝到伺服器上安裝，將檔案放到/root目錄下

# pip3 install --no-index --find-links="/root" redis
Collecting redis
Installing collected packages: redis
Successfully installed redis-3.5.3

訪問試試
