CentOS 7.9 配置Yum 本地源Everything

一、CentOS 7.9 配置Yum 本地源Everything

1 设置系统光盘开机自动挂载

增加内容

/dev/cdrom      /mnt  iso9660 defaults        0 0

vi /etc/fstab
#
# /etc/fstab
# Created by anaconda on Thu Oct 20 03:29:12 2022
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/centos-root /                       xfs     defaults        0 0
UUID=823a0431-42ac-49ee-864b-b06d5979faba /boot                   xfs     defaults        0 0
/dev/mapper/centos-swap swap                    swap    defaults        0 0
/dev/cdrom                                /mnt  iso9660 defaults        0 0

2 执行挂载命令

[root@localhost ~]# mount -a
mount: /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]# df -h
Filesystem               Size  Used Avail Use% Mounted on
devtmpfs                 1.3G     0  1.3G   0% /dev
tmpfs                    1.3G     0  1.3G   0% /dev/shm
tmpfs                    1.3G  9.5M  1.3G   1% /run
tmpfs                    1.3G     0  1.3G   0% /sys/fs/cgroup
/dev/mapper/centos-root   98G  1.3G   97G   2% /
/dev/sda1                497M  131M  367M  27% /boot
tmpfs                    263M     0  263M   0% /run/user/0
/dev/sr0                 9.5G  9.5G     0 100% /mnt

3 此目录下有内容，说明挂载成功

[root@localhost ~]# ls /mnt/
CentOS_BuildTag  EULA  images    LiveOS    repodata              RPM-GPG-KEY-CentOS-Testing-7
EFI              GPL   isolinux  Packages  RPM-GPG-KEY-CentOS-7  TRANS.TBL

4 配置本地Yum源

# 备份已有Yum源
mkdir /etc/yum.repos.d.bak
cp /etc/yum.repos.d/* /etc/yum.repos.d.bak/
rm -rf /etc/yum.repos.d/*

# 新建自己的本地Yum原
vim /etc/yum.repos.d/CentOS-xyz.repo 
[CentOS-XYZ]            # Yum的ID，必须唯一
name=CentOS7.9-Yum      # 描述信息
baseurl=file:///mnt     # /mnt 表示光盘的挂载点
enabled=1               # 启用
gpgcheck=0              # 取消验证，不用校验

5 测试

[root@localhost yum.repos.d]# yum install httpd
