如何解决 Linux 实例 pip 操作时的超时问题
pip 是当前最流行的 Python 安装包管理工具之一,很多阿里云用户会通过 pip 更新系统源。阿里云的 pip 源地址有以下三处:
(默认)公网:mirrors.aliyun.com
专有网络 VPC 内网:mirrors.cloud.aliyuncs.com
经典网络内网:mirrors.aliyuncs.com
现象描述
Linux 实例的 pip 请求偶有超时或者失败现象。目前,受影响的公共镜像有:
CentOS
Debian
Ubuntu
SUSE
OpenSUSE
Aliyun Linux
原因分析
pip 请求的默认访问地址为 mirrors.aliyun.com,要求访问该地址的实例能访问公网。当您的实例没有分配公网 IP 时,会出现 pip 请求超时故障。
解决方法
您可以使用以下方法中的任意一种解决问题。
方法一
为您的实例分配公网 IP,即为实例绑定一个 弹性公网 IP(EIP)。预付费实例还可以通过 升降配 重新分配公网 IP。
方法二
一旦出现 pip 响应延迟,您可以在 ECS 实例中运行脚本 fix_pypi.sh,然后再重试 pip 操作。
远程连接实例。
运行 wget http://image-offline.oss-cn-hangzhou.aliyuncs.com/fix/fix_pypi.sh 获取文件。
运行脚本:
VPC 实例:运行 bash fix_pypi.sh "mirrors.cloud.aliyuncs.com"。
经典网络实例:运行 bash fix_pypi.sh "mirrors.aliyuncs.com"。
重试 pip 操作。
以下为 fix_pypi.sh 的脚本内容:
#!/bin/bash function config_pip() { pypi_source=$1 if [[ ! -f ~/.pydistutils.cfg ]]; then cat > ~/.pydistutils.cfg << EOF [easy_install] index-url=http://$pypi_source/pypi/simple/ EOF else sed -i "s#index-url.*#index-url=http://$pypi_source/pypi/simple/#" ~/.pydistutils.cfg fi if [[ ! -f ~/.pip/pip.conf ]]; then mkdir -p ~/.pip cat > ~/.pip/pip.conf << EOF [global] index-url=http://$pypi_source/pypi/simple/ [install] trusted-host=$pypi_source EOF else sed -i "s#index-url.*#index-url=http://$pypi_source/pypi/simple/#" ~/.pip/pip.conf sed -i "s#trusted-host.*#trusted-host=$pypi_source#" ~/.pip/pip.conf fi } config_pip $1

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

Linux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.

The steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.

The core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.

The basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.

The key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.
