以下是文本的凝炼总结（149字）： CentOS 7 已于 2024 年 6 月 30 日停止维护，导致官方软件源失效。本文提供三种更换安装源的解决方案： 1. **自动脚本**：执行宝塔官方命令 `bash <(wget -qO- https://download.bt.cn/tools/fix_source.sh)` 一键替换。 2. **手动替换**： - **腾讯云源**：备份原配置后下载对应 repo 文件，执行 `yum clean all && yum makecache`（CentOS）或更新 APT 列表（Debian/Ubuntu）。 - **阿里云/清华源**：类似

如何更换LINXU系统的安装源？这篇教程可以教你解决-易云博客

CentOS 7 已于 2024年6月30日 正式停止维护（End of Life, EOL），此后将不再提供官方安全补丁、错误修复或功能更新，故其软件安装源也已被删除，无法正常使用yum指令安装软件。

故记录下解决方案，方便后续遇到可快速解决。

一、自动更换安装源代码（由宝塔官方提供）

前提要求系统已安装wget，若未安装会提示错误，可自助到wget官方下载包通过winscp等方式上传系统安装wget后再执行如下指令

bash <(wget --no-check-certificate -qO- https://download.bt.cn/tools/fix_source.sh)

二、更换安装源为腾讯云源

1、Centos系统更换安装源

备份当前的安装源，防止更换失败无法还原

\cp -rp /etc/yum.repos.d/ /etc/yum.repos.d_back

下载腾讯云的repo安装源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo

设置系统安装源为腾讯云的epel源

wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo

清理系统当前的yum缓存，并生成腾讯云的yum安装缓存

yum clean all
yum makecache

2、Debian系统更换安装源

备份当前的安装源，防止更换失败无法还原

\cp -rp /etc/apt/sources.list /etc/apt/sources.list_back

清空原有安装源

echo "" > /etc/apt/sources.list

设置新的安装源为腾讯云的epel源

①Debian9.x （stretch）

cat > /etc/apt/sources.list<<EOF
deb http://mirrors.cloud.tencent.com/debian stretch main contrib non-free
deb http://mirrors.cloud.tencent.com/debian stretch-updates main contrib non-free

EOF

更新软件包缓存

apt-get update -y

如果无法拉取https源的情况，请执行下面命令再重新执行

apt install apt-transport-https ca-certificates

二、更换安装源为阿里云源

1、Centos系统更换安装源

备份当前的安装源，防止更换失败无法还原

\cp -rp /etc/yum.repos.d/ /etc/yum.repos.d_back

下载阿里云的repo安装源

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


清理系统当前的yum缓存，并生成阿里云的yum安装缓存


yum clean all
yum makecache


三、更换安装源为清华源


1、Centos系统更换安装源


备份当前的安装源，防止更换失败无法还原


\cp -rp /etc/yum.repos.d/ /etc/yum.repos.d_back


注释原有mirrorlist


sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo


将baseurl的地址指向清华源


sed -i 's|#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' /etc/yum.repos.d/CentOS-*.repo


清理系统当前的yum缓存，并生成清华源的yum安装缓存


yum clean all
yum makecache


2、Ubuntu系统更换安装源


备份当前的安装源，防止更换失败无法还原


\cp -rp   /etc/apt/sources.list /etc/apt/sources.list_back
echo "" >/etc/apt/sources.list


添加清华源
