This article will explain in detail how to solve the timeout during the pip operation of Linux instances. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Pip is one of the most popular Python installation package management tools, and many Ali Cloud users update the system source through pip. Aliyun's pip source address has the following three points:

(default) Public network: mirrors.aliyun.com

Private network VPC intranet: mirrors.cloud.aliyuncs.com

Classic intranet: mirrors.aliyuncs.com

Phenomenon description

The pip request of a Linux instance occasionally times out or fails. Currently, the public images affected are:

CentOS

Debian

Ubuntu

SUSE

OpenSUSE

Aliyun Linux

Cause analysis

The default access address of pip request is mirrors.aliyun.com, which requires that the instance accessing this address can access the public network. When your instance does not have a public network IP assigned, the pip request timeout will occur.

Solution method

You can use any of the following methods to solve the problem.

Method one

Assign a public network IP to your instance, that is, bind an elastic public network IP (EIP) to the instance. Prepaid instances can also be reassigned to the public network IP through upgrade and downloading.

Method two

Once the pip response delay occurs, you can run the script fix_pypi.sh in the ECS instance, and then retry the pip operation.

Remotely connect to the instance.

Run wget http://image-offline.oss-cn-hangzhou.aliyuncs.com/fix/fix_pypi.sh to get the file.

Run the script:

VPC instance: run bash fix_pypi.sh "mirrors.cloud.aliyuncs.com".

Classic network example: run bash fix_pypi.sh "mirrors.aliyuncs.com".

Retry the pip operation.

The following is the content of the script for fix_pypi.sh:

#! / bin/bashfunction config_pip () {pypi_source=$1 if [[!-f ~ / .pydistutils.cfg]]; thencat > ~ / .pydistutils.cfg ~ / .pip/pip.conf
