yum，全称“Yellow dog Updater, Modified”，是一个专门为了解决包的依赖关系而存在的软件包管理器。类似于我们软件管家一样，一键安装软件并解决环境依赖关系，而且也可以管理并一键卸载。 |
云厂商的安装源 如果您的服务器是腾讯云的机器，建议设置腾讯云的安装源
1、CentOS7 安装源更换为腾讯源：
①、备份当前的安装源
- \cp -rp /etc/yum.repos.d/ /etc/yum.repos.d_back
下载腾讯云的安装源
- wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
②、设置腾讯云的epel源
- wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo
操作完后使用下面的命令进行清理当前的yum缓存，并生成腾讯云的安装缓存
- yum clean all
- yum makecache
2、Ubuntu系列安装源太老，请参考下面的清华源
3、Debian系列，只增加Debian9 和Debian10
备份Debian系列的安装源
- \cp -rp /etc/apt/sources.list /etc/apt/sources.list_back
①Debian9.x （stretch）
- echo "" > /etc/apt/sources.list
- 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
- #deb http://mirrors.cloud.tencent.com/debian stretch-backports main contrib non-free

- #deb-src http://mirrors.cloud.tencent.com/debian stretch-backports main contrib non-free
- #deb-src http://mirrors.cloud.tencent.com/debian stretch-proposed-updates main contrib non-free
- EOF
②、debian10.x（buster）
- \cp -rp /etc/apt/sources.list /etc/apt/sources.list_back
- echo "" > /etc/apt/sources.list
- cat > /etc/apt/sources.list<<EOF
- deb https://mirrors.cloud.tencent.com/debian/ buster main contrib non-free
- deb https://mirrors.cloud.tencent.com/debian/ buster-updates main contrib non-free

- deb-src https://mirrors.cloud.tencent.com/debian-security buster/updates main contrib non-free
- EOF
如果您的服务器是阿里云的服务器，可以指定阿里云的安装源
1、CentOS7：
①先备份当前的安装源目录
- \cp -rp /etc/yum.repos.d/ /etc/yum.repos.d_back
下载阿里云的安装源
- wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
②操作完成后，执行清理之前安装源的缓存命令，然后重新生成新的阿里云的安装源缓存
- yum clean all
- yum makecache
2、Ubuntu系列安装源太老，请参考下面的清华源
3、Debian系列安装源太老，请参考下面的清华源
国内优秀安装源---清华源
1、CentOS7
①、先备份当前的安装源目录
- \cp -rp /etc/yum.repos.d/ /etc/yum.repos.d_back
②、注释mirrorlist
- sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo
③、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
替换后，执行下面命令进行生成软件包的缓存
