Build an intranet yum repository using CentOS

Recently, I was working on an internal knowledge base system, requiring that it can only be used in an Intranet environment. I virtualized a server on a physical server. After installing the CentOS6.4 system, during environment deployment, it is found that the system is installed with minimal installation. Many Development Kits are not installed. However, the server cannot access the Internet and cannot use the Internet yum source to install the software package. As a result, I set up a yum source on the Intranet and sorted out the steps. I have done this before, but I have been very lazy and have not sorted it out. I want to sort it out today. The steps I have written are relatively detailed, so it looks long, but it is suitable for beginners.

(To facilitate the deployment of other servers of the same version in the same Intranet in the future, I use ftp as the yum source on the local machine, in the future, other servers in the Intranet can directly use the yum source using ftp .)

(1) mount the ISO image file to/media/cdrom.
Mount the downloaded CentOS-6.4-x86_64-bin-DVD1.iso image file to a directory in the following way, usually mounted to/media/cdrom:
Mount-t iso9660-o loop/root/CentOS-6.4-x86_64-bin-DVD1.iso/media/cdrom/
 
(2) install and start the vsftpd service.
The vsftpd service is not installed by default because the installation of my server is minimized. Enter the mounted directory here. Use rpm-ivh to install the vsftpd service.

[Root @ centos6cdrom] # rpm-ivh Packages/vsftpd-2.2.2-11.el6_3.1.x86_64.rpm
After the installation is complete, start the vsftpd service:
[Root @ centos6 cdrom] # service vsftpd restart
[Root @ centos6 cdrom] # chkconfig vsftpd on # Set vsftpd service to self-start
[Root @ centos6cdrom] # chkconfig -- list | grep vsftpd
Vsftpd0: Disable 1: Disable 2: Enable 3: Enable 4: Enable 5: Enable 6: Disable
 
(3) create a yum repository directory
After vsftpd is installed, the/var/ftp/pub/directory is automatically created by default. We create the yum repository directory under this directory and name it centos6.4, as shown below:
[Root @ centos6 cdrom] # mkdir-p/var/ftp/pub/centos6.4/
[Root @ centos6 cdrom] # cp-rf/media/cdrom/*/var/ftp/pub/centos6.4/# copy all files in the CD image to the yum repository directory
This is the directory structure after the copy is completed:
[Root @ centos6 cdrom] # cd/var/ftp/pub/centos6.4
[Root@centos6centos6.4] # ll

(4) create a yum source and update the software package dependency.
Manually create a repository dependency file. To create a yum source, you must install the createrepo software package. The installation of this software package depends on the following two packages:
Python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
Deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
Install these three packages together, as shown below:
[Root @ centos6cdrom] # rpm-ivh Packages/createrepo-0.9.9-17.el6.noarch.rpm Packages/python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm Packages/deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
 
[Root @ centos6 cdrom] # rm-rf/var/ftp/pub/centos6.4/repodata/# Delete the original dependency file and regenerate it.
[Root @ centos6 cdrom] # createrepo-v/var/ftp/pub/centos6.4/# recreate the dependency library file and regenerate the repodata directory
Next, modify the configuration file of the yum source address.
[Root @ centos6 ~] # Cd/etc/yum. repos. d/
[Root @ centos6 yum. repos. d] # for I in 'ls. /'; domv $ I-bak; done ;## put/etc/yum. repos. d/The files in the directory are renamed and backed up.
[Root @ centos6 yum. repos. d] # cp CentOS-Media.repo-bak CentOS-Media.repo
[Root @ centos6 centos6.4] # vi/etc/yum. repos. d/CentOS-Media.repo # use this file only, modify the following bold part of the content. You can change the directory according to your actual directory.
As follows:
 
C6-media
Name = CentOS-$ releasever-Media
# Baseurl = file: // media/CentOS/
File: // media/cdrom/
File: // media/cdrecorder/
Baseurl = ftp: // 192.168.0.109/pub/centos6.4/
Gpgcheck = 1
Enabled = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
 
Note:
Name = CentOS-$ releasever-Media custom description
Baseurl = file: // yum/Server specifies the protocol used and the location of the yum Source
Enabled = 1 whether to enable the yum repository, 1 for use, 0 for not use
Gpgcheck = 0 indicates whether the gpg key of the process is checked. 1 indicates check, and 0 indicates no check.
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-RedHat-release specify the location of the gpg KEY
 
Note:
Baseurl = specifies the yum source to use.
File indicates that the local yum source is used, in the format of file: // Source Path
Ftp means to use the ftp protocol to obtain the yum source, in the format of ftp: // sourceIP/repository directory
Http indicates that the Yum source is obtained using the http protocol in the format of http: // sourceIP/repository directory.
 
Gpgcheck = indicates whether to check the key. If you need to check the key, you can manually import it.
# Rpm -- import/etc/pki/rpm-gpg/gpg key file name
 
In the/etc/yum. repo. d/directory, it is best to have only one file with the suffix "repo", and rename other files to prevent interference.
