1、实验环境 2、测试网络环境 3、安装wget 4、下载阿里云repo文件。 5、清除yum缓存。 6、创建yum缓存。 7、效果测试。[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core)
服务器必须能够访问互联网,这里用ping www.baidu.com来测试,使用域名不但可以测试网络的连通性,也可以测试域名解析的功能。[root@localhost ~]# ping www.baidu.com PING www.a.shifen.com (14.215.177.39) 56(84) bytes of data. 64 bytes from 14.215.177.39 (14.215.177.39): icmp_seq=1 ttl=55 time=21.0 ms
若Linux系统中未安装wget,需要安装wget。wget是一个非交互的下载工具,参数 y 的作用是当安装过程中需要用户输入yes或no的时候,默认为yes。yum -y install wget
进入repo目录,删除系统自带的repo文件。下载阿里云的repo文件,作为服务器的yum仓库配置文件。[root@localhost ~]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# rm -rf * [root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/aliyun.repo http://mirrors.aliyun.com/repo/Centos-7.repo --2020-05-31 00:00:52-- http://mirrors.aliyun.com/repo/Centos-7.repo Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 218.67.61.95, 218.67.61.32, 61.131.39.13, ...

[root@localhost yum.repos.d]# yum clean all

随便安装一个软件测试,这里使用安装httpd测试。[root@localhost yum.repos.d]# yum -y install httpd Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies --> Running transaction check ---> Package httpd.x86_64 0:2.4.6-93.el7.centos will be installed --> Processing Dependency: httpd-tools = 2.4.6-93.el7.centos for package: httpd-2.4.6-93.el7.centos.x86_64 --> Processing Dependency: /etc/mime.types for package: httpd-2.4.6-93.el7.centos.x86_64 --> Processing Dependency: libaprutil-1.so.0()(64bit) for package: httpd-2.4.6-93.el7.centos.x86_64 --> Processing Dependency: libapr-1.so.0()(64bit) for package: httpd-2.4.6-93.el7.centos.x86_64 --> Running transaction check ---> Package apr.x86_64 0:1.4.8-5.el7 will be installed ---> Package apr-util.x86_64 0:1.5.2-6.el7 will be installed ---> Package httpd-tools.x86_64 0:2.4.6-93.el7.centos will be installed ---> Package mailcap.noarch 0:2.1.41-2.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================== Package Arch Version Repository Size ============================================================================================================================== Installing: httpd x86_64 2.4.6-93.el7.centos base 2.7 M Installing for dependencies: apr x86_64 1.4.8-5.el7 base 103 k apr-util x86_64 1.5.2-6.el7 base 92 k httpd-tools x86_64 2.4.6-93.el7.centos base 92 k mailcap noarch 2.1.41-2.el7 base 31 k Transaction Summary ============================================================================================================================== Install 1 Package (+4 Dependent packages) Total download size: 3.0 M Installed size: 10 M Downloading packages: warning: /var/cache/yum/x86_64/7/base/packages/apr-1.4.8-5.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY Public key for apr-1.4.8-5.el7.x86_64.rpm is not installed (1/5): apr-1.4.8-5.el7.x86_64.rpm | 103 kB 00:00:00 (2/5): apr-util-1.5.2-6.el7.x86_64.rpm | 92 kB 00:00:00 (3/5): httpd-tools-2.4.6-93.el7.centos.x86_64.rpm | 92 kB 00:00:00 (4/5): mailcap-2.1.41-2.el7.noarch.rpm | 31 kB 00:00:00 (5/5): httpd-2.4.6-93.el7.centos.x86_64.rpm | 2.7 MB 00:00:00 ------------------------------------------------------------------------------------------------------------------------------ Total 4.6 MB/s | 3.0 MB 00:00:00 Retrieving key from http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 Importing GPG key 0xF4A80EB5: Userid : "CentOS-7 Key (CentOS 7 Official Signing Key) <security@centos.org>" Fingerprint: 6341 ab27 53d7 8a78 a7c2 7bb1 24c6 a8a7 f4a8 0eb5 From : http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : apr-1.4.8-5.el7.x86_64 1/5 Installing : apr-util-1.5.2-6.el7.x86_64 2/5 Installing : httpd-tools-2.4.6-93.el7.centos.x86_64 3/5 Installing : mailcap-2.1.41-2.el7.noarch 4/5 Installing : httpd-2.4.6-93.el7.centos.x86_64 5/5 Verifying : apr-1.4.8-5.el7.x86_64 1/5 Verifying : httpd-tools-2.4.6-93.el7.centos.x86_64 2/5 Verifying : mailcap-2.1.41-2.el7.noarch 3/5 Verifying : httpd-2.4.6-93.el7.centos.x86_64 4/5 Verifying : apr-util-1.5.2-6.el7.x86_64 5/5 Installed: httpd.x86_64 0:2.4.6-93.el7.centos Dependency Installed: apr.x86_64 0:1.4.8-5.el7 apr-util.x86_64 0:1.5.2-6.el7 httpd-tools.x86_64 0:2.4.6-93.el7.centos mailcap.noarch 0:2.1.41-2.el7 Complete!
