RHEL installs software using rpm or tar packages. ubuntu is the most popular among many linux distributions, it has its own software center and RedHat has its own RHN, but it is charged. how to build its own local installation source? This is the first question I need to consider every time I do the system. The following shows how I installed the source. When www.2cto.com is installed with an rpm package, there is a dependency between the package and the package, which makes the installation inconvenient. Fortunately, the yum mechanism is used to control the package and overcome the dependency of the package. In several steps. 1. copy all rpm packages to a directory, put them in/mnt/local/. 2. install the createrepo package, rpm-ivh createrepo-0.9.8-4.el6.noarch 3, createrepo-v/mnt/local #-v specifies then in/etc/yum. repos. d/create the yum repository configuration file. end example of repo: # vi local. repo [base] # yum repository description name = local # repository name, which can be set to any one. here, it is just for me to view baseurl = file:///mnt/local/ # Rpm package path, that is, the installation source gpgcheck = 0 pointed to by yum # Run # yum clean all after it is not detected. of course, I can also use the RedHat system image as the yum source, method: mount the image file to the Directory, for example, mount-o loop-t iso9660 rhel6.iso/mnt/iso. add [server] name = RHEL baseurl = to the repo file file:///mnt/iso/ Gpgcheck = 0 # yum clean all
