导读:这篇文章主要介绍了Linux如何配置本地yum源(光盘镜像挂载),具有很好的参考价值,希望对大家有所帮助。如有错误或未考虑完全的地方,望不吝赐教
目录光盘镜像挂载登录到目标服务器查看镜像创建挂载目录挂载镜像挂载完毕进入挂载目录查看备份原始repo文件创建备份目录移动文件创建新的repo文件新建Centos-CDROM.repo文件刷新repo信息验证一下总结光盘镜像挂载

上传或者从其它服务器scp传输镜像CentOS-7-x86_64-DVD-1908.iso到目标服务器/mnt目录下(我这里从集群中别的服务器scp过来的):

scp传输命令(1024是服务器端口,需要改成你自己的,IP地址也是同样的需要修改):

如果服务器上有镜像就不用管下面这条命令

scp -P 1024 -r CentOS-7-x86_64-DVD-1908.iso root@192.168.67.200:/mnt/登录到目标服务器查看镜像[root@localhost mnt]# lltotal 4554750-rw-r--r-- 8 root root 4664066080 Dec 5 2016 CentOS-7-x86_64-DVD-1908.iso创建挂载目录[root@localhost mnt]# mkdir /mnt/iso[root@localhost mnt]# ls4554752-rw-r--r-- 8 root root 4664066080 Dec 5 2016 CentOS-7-x86_64-DVD-1908.isodrwxr-xr-x 8 root root 2048 Dec 5 2016 iso挂载镜像[root@localhost mnt]# mount CentOS-7-x86_64-DVD-1908.iso /mnt/iso/mount: /dev/sr0 is write-protected, mounting read-only

有的系统会提示错误需要使用mount -o loop -t iso9660

则将上面的mount语句换成下面语句:(如果你执行上面的mount语句不报错就跳过下面这条命令)

mount -o loop -t iso9660 CentOS-7-x86_64-DVD-1908.iso /mnt/iso挂载完毕进入挂载目录查看[root@localhost mnt]# cd iso/[root@localhost iso]# lltotal 654-rw-r--r-- 1 root root 14 Dec 5 2016 CentOS_BuildTagdrwxr-xr-x 3 root root 2048 Dec 5 2016 EFI-rw-r--r-- 1 root root 215 Dec 10 2015 EULA-rw-r--r-- 1 root root 18009 Dec 10 2015 GPLdrwxr-xr-x 3 root root 2048 Dec 5 2016 imagesdrwxr-xr-x 2 root root 2048 Dec 5 2016 isolinuxdrwxr-xr-x 2 root root 2048 Dec 5 2016 LiveOSdrwxrwxr-x 2 root root 630784 Dec 5 2016 Packagesdrwxrwxr-x 2 root root 4096 Dec 5 2016 repodata-rw-r--r-- 1 root root 1690 Dec 10 2015 RPM-GPG-KEY-CentOS-7-rw-r--r-- 1 root root 1690 Dec 10 2015 RPM-GPG-KEY-CentOS-Testing-7-r--r--r-- 1 root root 2883 Dec 5 2016 TRANS.TBL

镜像已经被解压到挂载目录。

备份原始repo文件创建备份目录mkdir /etc/yum.repos.d/bak移动文件mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/创建新的repo文件新建Centos-CDROM.repo文件vi /etc/yum.repos.d/Centos-CDROM.repo[CDROM]name=CentOS-$releasever - CDROMbaseurl=file:///mnt/isogpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7刷新repo信息[root@localhost ~]# yum clean allLoaded plugins: fastestmirror, langpacksCleaning repos: CDROMCleaning up everythingCleaning up list of fastest mirrors[root@localhost ~]# yum makecacheLoaded plugins: fastestmirror, langpacksCDROM | 3.6 kB 00:00:00 (1/4): CDROM/group_gz | 155 kB 00:00:00 (2/4): CDROM/primary_db | 3.0 MB 00:00:00 (3/4): CDROM/filelists_db | 3.0 MB 00:00:00 (4/4): CDROM/other_db | 1.3 MB 00:00:00 Determining fastest mirrorsMetadata Cache Created验证一下[root@localhost ~]# yum -y install mariadbLoaded plugins: fastestmirror, langpacksLoading mirror speeds from cached hostfileResolving Dependencies--> Running transaction check---> Package mariadb.x86_64 1:5.5.52-1.el7 will be installed--> Processing Dependency: mariadb-libs(x86-64) = 1:5.5.52-1.el7 for package: 1:mariadb-5.5.52-1.el7.x86_64--> Running transaction check---> Package mariadb-libs.x86_64 1:5.5.52-1.el7 will be installedRemoving mariadb-libs.x86_64 1:5.5.52-1.el7 - u due to obsoletes from installed mysql-community-libs-5.6.37-2.el7.x86_64Removing mariadb.x86_64 1:5.5.52-1.el7 - u due to obsoletes from installed mysql-community-client-5.6.37-2.el7.x86_64--> Restarting Dependency Resolution with new changes.--> Running transaction check---> Package mariadb.x86_64 1:5.5.52-1.el7 will be installed---> Package mariadb-libs.x86_64 1:5.5.52-1.el7 will be installed--> Finished Dependency Resolution总结

可以看到没问题了,本地yum源已经可以使用了。

以上为个人经验,希望能给大家一个参考,也希望大家多多支持好吧啦网。
