一般公司的服务器都是和外网隔离的，这个如果没有内部pip源的话，想要安装python的模块就需要去python官网一个一个下载依赖模块的包，然后逐个安装，这样做非常耗时间。

我们今天用的办法就是现在我们能够连接公网的linux机器上面先使用pip命令安装好我们需要的python模块。然后再将需要的模块一键下载并拷贝到服务器上一键安装。步骤如下：

前提条件：

　　如果服务器是linux的，我们就需要一个能连公网的linux，不能使用windows是因为，有很多模块linux和windows两个平台不是共用的，在安装的时候会报错。

步骤：

1、在能连接公网的linux机器上使用pip命令安装好需要的模块。（pip安装的好处是：会自动帮你把依赖模块安装好）

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ sh

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ docker-py

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ fabric

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ paramiko

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ psutil

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ PyMySQL

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ redis

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ requests

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ selenium

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ SQLAlchemy

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ tornado

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ xlrd

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ xlwt

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ xmltodict

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ celery

pip3 install -i https://mirrors.aliyun.com/pypi/simple/ celery-flower

2、然后在能连接公网的机器上执行pip freeze>python3_module.txt，这样就可以将你之前安装的模块列表导出来

3、列表导出来以后就需要根据这个列表去把模块的代码文件从公网下载下来，执行mkdir python3_package && pip3 download -r python3_modules.txt -d python3_packages/ -i https://mirrors.aliyun.com/pypi/simple/  ，这里我们使用了阿里的源，这样下载的速度会快很多

4、将下载完的文件夹打包，mv python3_modules.txt python3_packages/ && tar -czf python3_packages.tar.gz python3_packages，然后将打包完的文件上传到服务器上解压，tar -xzf python3_packages.tar.gz。

5、在服务器上安装我们的模块（前提需要安装和能连接公网的linux机器版本相同的python），cd python3_packages && /opt/samp/venv/python3/bin/pip3 install --no-index --find-links=file:. -r python3_modules.txt，等待安装完成即可，这样可以避免让人奔溃的依赖模块一个一个安装问题。

[root@itsasitapp213 python3_packages]# /opt/samp/venv/python3/bin/pip3 install --no-index --find-links=file:. -r python3_modules.txt
