Based on yum package management, yum packages can be automatically downloaded and installed from the specified server, and dependencies can be automatically processed. all dependent software packages can be installed at one time without the need for tedious download and installation. Software package sources available for Yum download include the Fedora package and the Fedora Extras from yumfusion and yum.livna.org, which are all maintained by the Linux community and are basically free software. All packages have an independent GPG signature, mainly for your system security. For users of Fedora core 4.0, the yum.livna.org signature is automatically imported and installed. The graphic front-end of the graphic front-end Yum mainly includes yumex and kyum. They are not independent of Yum, but the Yum graphics front-end. that is to say, they are both based on Yum installation and configuration while installing and using Yumex and kyum; therefore, you must install and configure Yum before using Yumex or kyum. Unzip 1.2yum installation ----------------------------------------------- Method 1: (recommended) Step 1: create a folder and copy all files on the disc to this folder: [root @ localhost ~] # Mkdir/yum [root @ localhost ~] # Cp-rvf/misc/cd/*/yum Step 2: Back up the repodata file. Because this file exists in four folders, backup is required. [Root @ localhost ~] # Mv/yum/Server/repodata. bak [root @ localhost ~] # Mv/yum/VT/repodata. bak [root @ localhost ~] # Mv/yum/Cluster/repodata. bak [root @ localhost ~] # Mv/yum/ClusterStorage/repodata. bak Step 3: install the toolkit: [root @ localhost ~] # Rpm-ivh/yum/Server/createrepo-0.4.11-3.el5.noarch.rpm Step 4: generate repository database: [root @ localhost ~] # Createrepo-g/yum/Server/repodata. bak/comps-rhel5-server-core.xml/yum/Server/[root @ localhost ~] # Createrepo-g/yum/VT/repodata. bak/comps-rhel5-vt.xml/yum/VT/[root @ localhost ~] # Createrepo-g/yum/Cluster/repodata. bak // yum/Cluster [root @ localhost ~] # Createrepo-g/yum/ClusterStorage/repodata. bak/comps-rhel5-cluster-st.xml/yum/ClusterStorage/Step 5: view the repository data file: [root @ localhost ~] # Ls/yum/Server/repodata/comps-rhel5-server-core.xml // classification of this file software package group. Filelists.xml.gz other.xml.gz primary.xml.gz // these three files are Package List files. Repomd. xml // This file is MD5 verification information. These files are available under/yum/VT/yum/Cluster/yum/ClusterStorage. To update the software package, you only need to put the downloaded software package in the Server or three other directories, and then use step 4 to regenerate the database file. Step 6: configure the client: [root @ localhost ~] # Cp/etc/yum. repos. d/rhel-debuginfo.repo/etc/yum. repos. d/chenbin. repo [root @ localhost ~] # Vi/etc/yum. repos. d/chenbin. repo [rhel-Server] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///yum/Serverenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release [Rhel-VT] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///yum/VTenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release [Rhel-Cluster] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///yum/Clusterenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release [Rhel-ClusterStorage] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///yum/ClusterStorageenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release Step 7: view the software list. --------------------------------------------- Method 2: Step 1: Create a new folder and copy all the content of the CD to the folder: [root @ localhost ~] # Mkdir/yum [root @ localhost ~] # Cp-rvf/misc/cd/*/yum Step 2: install the toolkit: [root @ localhost ~] # Rpm-ivh/yum/Server/createrepo-0.4.11-3.el5.noarch.rpm Step 3: generate repository database: [root @ localhost ~] # Cd/yum [root @ localhost yum] # createrepo. // pay attention to the following. step 4: view the file: The file function is the same as that in [root @ localhost yum] # ls/yum/repodata/filelists.xml.gz other.xml.gz primary.xml.gz repomd. step 5 of xml: Client Configuration: [root @ localhost ~] # Cp/etc/yum. repos. d/rhel-debuginfo.repo/etc/yum. repos. d/chenbin. repo [root @ localhost ~] # Vi/etc/yum. repos. d/chenbin. repo [rhel-chenbin] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///yum/enabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release Clear the cache during yum installation: [root @ localhost ~] # Yum clean all at this point, yum installation is complete, but after installation using this method, the list of application-add and delete software is empty, but you can use yum to install software. [Root @ localhost ~] # Yum install/yum/Server/httpd-2.2.3-22.el5.i386.rpm [root @ localhost ~] # Yum remove httpd ------------------------------------------------- 1.3 Method 3: first put the disc into the optical drive, and then copy the configuration file: [root @ localhost ~] # Cp/etc/yum. repos. d/rhel-debuginfo.repo/etc/yum. repos. d/chenbin. repo finally edit the configuration file: [root @ localhost ~] # Vi/etc/yum. repos. d/chenbin. repo [rhel-Server] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///misc/cd/Serverenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release [Rhel-VT] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///misc/cd/VTenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release [Rhel-Cluster] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///misc/cd/Clusterenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release [Rhel-ClusterStorage] name = Red Hat Enterprise Linux $ releasever-$ basearch-Debugbaseurl = file:///misc/cd/ClusterStorageenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release Clear Cache: [root @ localhost ~] # Yum clean all after installation, there is also a list in the application-add and delete software. Can I use yum for installation? Load [root @ localhost ~] # Yum install/misc/cd/Server/httpd-2.2.3-22.el5.i386.rpm [root @ localhost ~] # Yum remove httpd if you take out the CD, you will not be listed in application-add and delete software, as long as you put it on the CD.
