Centos7的yum使用国内源阿里源163源等提高下载速度

Centos7的yum使用国内源阿里源163源等提高下载速度 原理是下载替换 /etc/yum.repos.d/CentOS-Base.repo 文件 可用 curl 或 wget 工具 curl 在CentOS7最小安装中就自带, wget要另外下载, 比如 sudo yum install wget curl -o是小写 , wget -O是大写

一步使用阿里源的脚本

阿里源

阿里开发者社区镜像站 阿里开发者社区镜像站 CentOS 镜像 CentOS过期源（centos-vault）其中CentOS-Vault.repo对应的是发行该镜像时的yum源版本，使用该镜像源可以下载发行镜像时的yum源。

sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

或

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

实质就是将以下内容取名为Centos-Base.repo文件放到/etc/yum.repos.d/文件夹中

# 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.

对于 CentOS 7，使用以下命令替换默认配置

sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org/centos|baseurl=https://mirrors.ustc.edu.cn/centos|g' \
         -i.bak \
         /etc/yum.repos.d/CentOS-Base.repo

以上命令只替换了默认启用的仓库。替换之后请运行 yum makecache 更新缓存。

建议先备份 /etc/yum.repos.d/ 内的文件。

然后编辑 /etc/yum.repos.d/ 中的相应文件，在 mirrorlist= 开头行前面加 # 注释掉；并将 baseurl= 开头行取消注释（如果被注释的话）。 对于 CentOS 7 ，请把该行内的域名（例如mirror.centos.org）替换为 mirrors.tuna.tsinghua.edu.cn。 对于 CentOS 8 ，请把 mirror.centos.org/$contentdir 替换为 mirrors.tuna.tsinghua.edu.cn/centos。

以上步骤可以被下方的命令一步完成

# 对于 CentOS 7
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' \
         -i.bak \
         /etc/yum.repos.d/CentOS-*.repo

# 对于 CentOS 8
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org/$contentdir|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos|g' \

安装epel源 , 使用epel的阿里源

什么是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。装上了 EPEL之后，就相当于添加了一个第三方源。 为什么要用EPEL？

RHEL以及他的衍生发行版如CentOS Linux为了稳定，官方的rpm repository提供的rpm包往往是很滞后的，当然了，这样做这是无可厚非的，毕竟这是服务器版本，安全稳定是重点，官方的rpm repository提供的rpm包也不够丰富，EPEL恰恰可以解决这两方面的问题。 简单来说

如果某个软件在yum库里面找不到的话，就可以考虑安装epel-release，epel-release可以扩充yum库。 如何安装epel-release？

#  安装epel
sudo yum install -y epel-release

使用阿里提供的epel源

sudo curl -o /etc/yum.repos.d/epel-7.repo  http://mirrors.aliyun.com/repo/epel-7.repo

或

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