Python3.6.5和pip安装脚本以及离线安装pip包【原创】

1、将Python3.6.5安装包及python36_install.sh放在同一目录

# 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

安装脚本内容

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

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、执行脚本

sh python36_install.sh

3、会自动安装好Python和pip，并做成软链接，与现有Python不冲突

4、离线安装pip包

有的生产系统服务器不允许连接内网，所以要用离线方法安装

先在能上网服务器下载

pip3 install redis --download /tmp

# 下载后的文件以whl后缀的文件，在/tmp目录
-rw-r--r--   1 root root   71K  8月 28 16:30 redis-3.5.3-py2.py3-none-any.whl

将文件拷贝到服务器上安装，将文件放到/root目录下

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

访问试试

# python3
Python 3.6.5 (default, Aug 28 2020, 17:11:02) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import redis
>>> 

5、离线下载时报错，pip新离线下载方法

[root@hch tmp 10:46:56]# pip36 install requests --download /tmp/offline_packages

Usage:   
  pip36 install [options] <requirement specifier> [package-index-options] ...
  pip36 install [options] -r <requirements file> [package-index-options] ...
  pip36 install [options] [-e] <vcs project url> ...
  pip36 install [options] [-e] <local project path> ...
  pip36 install [options] <archive url/path> ...

no such option: --download

# 离线下载requests库，如果豆瓣源不是https还要添加信任
pip36 download requests --trusted-host pypi.douban.com

pip36 download requests

# 在无外网服务器上安装， requests为离线包目录 # pip3 install --no-index --find-links=file:./requests requests Collecting requests Collecting certifi>=2017.4.17 (from requests) Collecting idna<3,>=2.5 (from requests) Collecting urllib3<1.27,>=1.21.1 (from requests) Collecting chardet<5,>=3.0.2 (from requests) Installing collected packages: certifi, idna, urllib3, chardet, requests Successfully installed certifi-2020.12.5 chardet-4.0.0 idna-2.10 requests-2.25.1 urllib3-1.26.3
