【Linux】Centos安装Python3

阅读数: 2022-02-10

前言

环境: centos7

1 2	[root@tpl-centos7 Python-3.7.0]# uname -a Linux tpl-centos7 3.10.0-1127.13.1.el7.x86_64 #1 SMP Tue Jun 23 15:46:38 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

更换为国内源

一、阿里云源

备份

1	mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载新的CentOS-Base.repo 到/etc/yum.repos.d/

1	wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

清除重建缓存

1 2	yum clean all # 清除系统所有的yum缓存 yum makecache # 生成yum缓存

阿里源现在重建的时候有一个地址无法访问了，不知道是不是我的网路原因，故用了清华大学源

二、清华大学源【推荐】

首先备份 CentOS-Base.repo

1	mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

将清华大学镜像仓库信息写入 /etc/yum.repos.d/CentOS-Base.repo

1	vim /etc/yum.repos.d/CentOS-Base.repo

将 CentOS-Base.repo 中的内容更新为下面的内容：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

[base]
