We have a development environment offline. There are some Python developers and users who want to use non-standard packages from PyPI website. After doing comparison, I decided to create a PyPI Mirror with devpi-server. Steps to create will be covered in the coming sections.

Installing devpi-server, devpi-web, devpi-client packages on our machine:

```
pip install -q -U devpi-server devpi-web devpi-client
```

Show version:

```
$ devpi-server --version
5.2.0
$ devpi --version
devpi-client 5.1.1
```

Initialize devpi-server:

To initialize devpi-server issue:

```
$ devpi-init
INFO  NOCTX Loading node info from /tmp/home/.devpi/server/.nodeinfo
INFO  NOCTX generated uuid: cfd8cd68eb384f349935a210670415fb
INFO  NOCTX wrote nodeinfo to: /tmp/home/.devpi/server/.nodeinfo
INFO  NOCTX DB: Creating schema
INFO  [Wtx-1] setting password for user 'root'
INFO  [Wtx-1] created user 'root' with email None
INFO  [Wtx-1] created root user
INFO  [Wtx-1] created root/pypi index
INFO  [Wtx-1] fswriter0: committed: keys: '.config','root/.config'
```

Create the config file for it:

```
$ devpi-gen-config
It is highly recommended to use a configuration file for devpi-server, see --configfile option.
wrote gen-config/crontab
wrote gen-config/net.devpi.plist
wrote gen-config/launchd-macos.txt
wrote gen-config/nginx-devpi.conf
wrote gen-config/supervisor-devpi.conf
wrote gen-config/supervisord.conf
wrote gen-config/devpi.service
wrote gen-config/windows-service.txt
```

Then we start supervisored using a config which includes the generated file:

```
$ supervisord -c gen-config/supervisord.conf  # you must install supervisord first.
```

You now have a server listening on [http://localhost:3141](http://localhost:3141/). Please note that the default host is 127.0.0.1, i.e., localhost, and default port is 3141.

Change host and port by editing gen-config/supervisor-devpi.conf file:

![supervisor-devpi.conf_.png](/media/202111/2021-11-19_101636_844203.png)

Then stop and start devpi-server by issuing:

```
$ supervisorctl -c gen-config/supervisord.conf shutdown
$ supervisord -c gen-config/supervisord.conf
```

Now, our devpi-server is ready!

We can visit [http://localhost:3141](http://localhost:3141/) now. Note that default PyPI site is [https://pypi.org/simple/](https://pypi.org/simple/).

![mirror_url.png](/media/202111/2021-11-19_101716_318048.png)

If we want to change the default mirror site, how can we do that? We should be using devpi-client to do this change.

```
$ devpi use http://localhost:3141       # which url devpi-client uses
$ devpi login root                      # login as root user, 默认密码为空
$ devpi user -m root password=devpi123  # set password for root user
$ devpi index root/pypi mirror_url="https://mirrors.aliyun.com/pypi/simple"  # set mirror_url for devpi-server
```

Now let’s revisit [http://localhost:3141](http://localhost:3141/) and the mirror_url has been changed to [https://mirrors.aliyun.com/pypi/simple](https://mirrors.aliyun.com/pypi/simple).

The most exciting moment is coming, visit [http://localhost3141/root/pypi/+simple/](http://localhost3141/root/pypi/+simple/) you can see the whole indices that mirrored from PyPI website.

We can also install a package from our PyPI mirror site by issuing:

```
pip install -i http://localhost:3141/root/pypi/+simple/ simplejson
```

Congrats, Our work is done perfectly.

客户端设置：
```
pip config set global.index-url http://10.10.10.10/pypi/+simple
pip config set global.trusted-host 10.10.10.10
```
