1.下载和安装相关包

前提是有GCC
sudo yum install gcc -downloadonly —downloaddir=/home/ceph-admin
Downloading packages:
(1/2): cpp-4.8.5-44.el7.x86_64.rpm
(2/2): gcc-4.8.5-44.el7.x86_64.rpm

sudo rpm -ivh libgcc-4.8.5-44.el7.x86_64.rpm
sudo rpm -ivh libgomp-4.8.5-44.el7.x86_64.rpm
sudo rpm -ivh cpp-4.8.5-44.el7.x86_64.rpm
sudo rpm -U libgomp-4.8.5-44.el7.x86_64.rpm
sudo rpm -U libgcc-4.8.5-44.el7.x86_64.rpm 
sudo rpm -ivh gcc-4.8.5-44.el7.x86_64.rpm 
gcc -v
#能看到版本说明安装成功

先安装GCC，然后源码安装python3.9.0

tar -zxvf Python-3.9.0.tgz 
cd Python-3.9.0
sudo ./configure prefix=/usr/local/python3
sudo make 
sudo make install
#安装好了，测试一下
python3

sudo pip3 install pip2pi-0.8.1-py2.py3-none-any.whl
mkdir ~/pypi
sudo vim /etc/nginx/nginx.conf
sudo systemctl restart nginx

server {
        listen       8000;
        server_name  192.169.5.59:8000;
        charset utf-8,gbk;
        location / {
                root /data/pip3_source;
                autoindex on;
                autoindex_exact_size off; #显示文件的大小
                autoindex_localtime on; #显示文件时间
                #limit_rate_after 5m; #5分钟后下载速度限制为200k
                #limit_rate 200k;
        }
        access_log logs/pip.log;
}

[global]
index-url=http://ip:port/pypi/simple

我要在pypi目录下放python的各种whl包，命令是pip2tgz yourpath packagename
批量下载pip2tgz path -r requirements.txt

#下载包到data目录
pip2tgz data numpy
pip2tgz data pillow==1.0
cd data 
#在data目录里建立索引，会自动生成simple文件，这是个索引，里面有每个python包的位置
dir2pi data

里面的html文件内容如图，点进去可以下载包，所以nginx的主页要设置在这里
