2) Create .repo file under /etc/yum.repos.d, or you can download any repo template to modify
# 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] name=CentOS-$releasever - Base - mirrors.neusoft.edu.cn failovermethod=priority baseurl=http://mirrors.neusoft.edu.cn/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.neusoft.edu.cn/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates - mirrors.neusoft.edu.cn failovermethod=priority baseurl=http://mirrors.neusoft.edu.cn/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.neusoft.edu.cn/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - mirrors.neusoft.edu.cn failovermethod=priority baseurl=http://mirrors.neusoft.edu.cn/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.neusoft.edu.cn/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus - mirrors.neusoft.edu.cn failovermethod=priority baseurl=http://mirrors.neusoft.edu.cn/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.neusoft.edu.cn/centos/RPM-GPG-KEY-CentOS-7 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib - mirrors.neusoft.edu.cn failovermethod=priority baseurl=http://mirrors.neusoft.edu.cn/centos/$releasever/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.neusoft.edu.cn/centos/RPM-GPG-KEY-CentOS-7
3) Since the default $releasever is set to "7server" , I need to change this to "7", or yum cannot find corresponding folder in mirror site
vi /etc/yum/vars/releasever , input 7 , then save the file
4) yum install -y /home/<UserName>/Download/microsoft-edge-dev-88.0.685.3-1.x86_64.rpm
