RHEL8上配置yum源

使用iso文件的话：

mount -o loop rhel-8.0-x86_64-dvd.iso /mnt/cdrom

使用光驱的话：

 mount /dev/cdrom /mnt/cdrom

编辑rhel8.repo文件，文件内容见：

[root@rhel8server1 yum.repos.d]# cat /etc/yum.repos.d/rhel8.repo 
[InstallMedia-BaseOS]
name=Red Hat Enterprise Linux 8 - BaseOS
metadata_expire=-1
gpgcheck=1
enabled=1
baseurl=file:///mnt/cdrom/BaseOS/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[InstallMedia-AppStream]
name=Red Hat Enterprise Linux 8 - AppStream
metadata_expire=-1
gpgcheck=1
enabled=1
baseurl=file:///mnt/cdrom/AppStream/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[root@rhel8server1 yum.repos.d]# 

清理:

[root@rhel8server1 yum.repos.d]# dnf clean all
[root@rhel8server1 yum.repos.d]# subscription-manager clean

安装iptraf-ng命令：
 

[root@rhel8server1 yum.repos.d]# dnf install iptraf-ng
