centos creates a local yum repository

centos creates a local yum repository

1. Create the relevant directories you need to use
   
   • /mnt/dvd1 and /mnt/dvd2 are used to mount centos images
   • /mnt/dvd3 Place the merged image file
   • /mnt/iso to place the original centos image file
   • mkdir -p /mnt/dvd1 /mnt/dvd2 /mnt/dvd3 /mnt/iso create directory command
2. Upload the two dvd image files on the local machine to the centos server, and then mount them to the corresponding directories respectively
   
   • mount //local machine ip/shared directory name/centos server corresponding directory/centos -o username=local machine username, password=local machine password, nounix, noserverino
   • Copy the two original image files to the /mnt/iso directory
   • mount -o loop /mnt/iso/CentOS-6.5-x86_64-bin-DVD1.iso /mnt/dvd1
   • mount -o loop /mnt/iso/CentOS-6.5-x86_64-bin-DVD2.iso /mnt/dvd2
3. copy file
   
   • First, copy all files under /mnt/dvd1 to /mnt/dvd3 directory, then, copy only all rpm files in Packages directory under /mnt/dvd2 to /mnt/dvd3/Packages directory
   • cp -av / mnt / dvd1 / * / mnt / dvd3 /
   • cp -av /mnt/dvd2/Packages/*.rpm / mnt / dvd3 / Packages /
4. Merge TRANS.TBL
   
   • Append the information of TRANS.TBL in /mnt/dvd2 to the back of TRANS.TBL in /mnt/dvd1, and save in order
   • cat /mnt/dvd2/Packages/TRANS.TBL >> /mnt/dvd3/Packages/TRANS.TBL
   • mv /mnt/dvd3/Packages/{TRANS.TBL,TRANS.TBL.BAK}
   • sort /mnt/dvd3/Packages/TRANS.TBL.BAK > /mnt/dvd3/Packages/TRANS.TBL
   • rm -rf /mnt/dvd3/Packages/TRANS.TBL.BAK
   • /mnt/dvd3 is already a merged directory and can be used as a local yum source
5. Backup YUM configuration file
   
   • cd /etc/yum.repos.d
   • rename .repo .repo.bak *.repo
6. Generate a new YUM configuration file
   
   • vi /etc/yum.repos.d/CentOS-Media.repo
7. Update YUM source
   
   • yum clean all
   • yum upgrade
