EPEL

EPEL的全称叫 Extra Packages for Enterprise Linux 。EPEL是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。

官方网址为：https://fedoraproject.org/wiki/EPEL

Centos安装命令： sudo yum install epel-release

rpmfusion

RPM Fusion provides software that the Fedora Project or Red Hat doesn’t want to ship. That software is provided as precompiled RPMs for all current Fedora versions and current Red Hat Enterprise Linux or clones versions; you can use the RPM Fusion repositories with tools like yum and PackageKit.

RPM Fusion is a merger of Dribble, Freshrpms, and Livna; our goal is to simplify end-user experience by grouping as much add-on software as possible in a single location. Also see our FoundingPrinciples.

官方网站为 https://rpmfusion.org/

Remi repository

Remi repository 是包含最新版本 PHP、MySQL、Python 包的 Linux 源，由 Remi 提供维护。

官方网站为 http://rpms.remirepo.net/。

修改镜像容器存储地址（GraphRoot）

podman info # 找到配置文件地址，默认是/etc/containers/storage.conf

store:
  configFile: /etc/containers/storage.conf
  containerStore:

打开或者新建配置文件，修改GraphRoot和runroot地址。

[storage]
# Default Storage Driver
driver = "overlay"

# Temporary storage location
runroot = "/home/podman/containers/temp_storage"

# Primary Read/Write location of container storage
graphroot = "/home/podman/containers/storage"

修改镜像源地址

升级python所有的包

pip install pip-review # 安装第三方包pip-review

pip-review #查看可更新

pip-review --auto #自动批量升级

pip-review --interactive #以交互方式运行，对每个包进行升级

Python更改pip源

创建配置文件

mkdir ~/.pip
cd ~/.pip
vim pip.conf

编辑 pip.conf文件，添加如下内容：

[global]
index-url = https://mirrors.aliyun.com/pypi/simple
[install]
trusted-host=mirrors.aliyun.com

中国国内推荐的pip源如下：
