Linux Software Installation

first, the Linux software name version identification 650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M02/9D/40/wKiom1l8cIyQ-jj3AABy0kEIMlY663.png "title=" N ' Df1[bo~uf (0 (acimpmse8.png "alt=" Wkiom1l8ciyq-jj3aaby0keimly663.png "/>

Second, Linux rpm installation software

Rpm-q Name	Query whether the software is installed
RPM-IVH name.rpm	Installing the Software
RPM-E Name	Uninstalling software
RPM-QL Name	Querying software generation files
RPM-QLP name.rpm	What files are generated when you query the system for installation
Rpm-qa |gerp name.rpm	Query whether the software is installed
Rpm-qa	Querying the name of all software in the system
RPM-QC Name	View the configuration files for installed software
RPM-QP name.rpm	Query the software installed name
RPM-IVH name.rpm--force	Force installation but cannot ignore file dependencies
RPM-IVH name.rpm--nodeps--force	Ignore dependencies and force installation
Rpm-qi Name	View software Information
RPM-KV name.rpm	Detects if the software has been changed
RPM-QP name.rpm--scripts	View the actions of the software during the installation or uninstallation process

Note: RPM installation software is not a good solution for dependencies between different RPMs, and the following Yum can be a good solution for installing dependencies between different installation packages.

Second, Linux yum installation software

Although Yum can be a good solution to the dependency between RPMs, there must be a Yum source before using Yum.

Yum Install Softwarename	Installing the Software
Yum Repolist	List Yum Source information
Yum Remove Softwarename	Uninstalling software
Yum List Softwarename	See if the software source has software
Yum List	List all software names
Yum List installed	List the names of installed software
Yum available	List software names that can be installed with Yum
Yum Clean All	Emptying the Yum cache
Yum Search Softwareinfo (features of the software)	Search software name based on software information
Yum whatprovides filename	Find the package containing the filename in the Yum source
Yum Update	Update Software
Yum history	View System software changes history
Yum Reinstall Softwarename	Re-install
Yum Info softwarename	View software Information
Yum Groups list	View Software group information
Yum Groups Info Softwaregroup	View Software group information
Yum Groups install Softwaregroup	Installing components
Yum groups Remove Softwaregroup	Uninstalling components

1, download the local ISO image file on the network, and make it into a yam source.

1. Delete all files under the/etc/yum.repos.d/directory in this machine, and it is best to back it up.

Vim/etc/yum.repos.d/rhel.repo[server] #自定义软件仓库名称name =rhel7.0 #自定义软件仓库描述 baseurl=file:///var/www/html/rhel7.0 #将本地的 Image as Yum source gpgcheck=0 #不检测gpgkey

2. Mount the downloaded ISO file to the/var/www/html/rhel7.1 directory

Mount rhel-server-7.1-x86_64-dvd.iso/var/www/html/rhel7.1

This is for the sake of convenience to make the host known as the network Yum source, so he mounted to the HTTP service's default Site Directory

Then execute yum clean all to empty the Yum cache to identify the new configuration

Note: If you have a local Yum source, you can continue to add a mirrored address to the Rhel.repo file in the/ETC/YUM.REPOS.D directory, for example, my/tools contains a large number of third-party software RPM packages:

[Server2]name=rhel7.0baseurl=file:///toolsgpgcheck=0

After you add the save, empty the Yum cache to identify the new configuration, and if you perform Yum to install the third-party software, the following error will appear at the bottom:

Failure:repodata/repomd.xml from soft: [Errno) No more mirrors to Try.file:///tools/repodata/repomd.xml: [Errno] C Url#37-"couldn ' t open file/tools/repodata/repomd.xml"

He suggested that the/tools/repodata/directory was not repomd.xml file, you need to execute createrepo-v this command, add RPM to the DB database, this will appear repodata this directory, so you

Createrepo-v/tools[[email protected] yum.repos.d]# ll/tools |grep repodatadrwxr-xr-x 2 root root 4096 Jul 28 2 2:23 Repodata

2. Use the host as a Yum source for other machines: for example, virtual machines

Depending on the Yum source with the host on top, do the following

On the host:

Download install httpd service: Yum install httpd-y

You can see the input 172.25.254.31/rhel7.0 in the browser

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M01/9D/3F/wKioL1l8bFvQJlZUAABcQ2FSlwQ014.png "title=" Screenshot from 2017-07-29 10-26-30.png "alt=" Wkiol1l8bfvqjlzuaabcq2fslwq014.png "/>

on other machines, delete all files under the/etc/yum.repos.d/directory, preferably back up .

vim/etc/yum.repos.d/rhel.repo[client]name=rhel7.0baseurl=172.25.254.31/rhel7.0 gpgcheck=0# Execute yum Clean all # after exiting save Emptying the Yum cache

3, the Yum source on the network as the host's Yum source

Root above the client machine above the configuration is basically the same, but its Yum source repository of different URLs, but also in addition to the/etc/yum.repos.d/directory files.

Vim/etc/yum.repos.d/rhel.repo[rhel7.0]name=rhel7.0baseurl= here fill out your Yum source URL gpgcheck=0# exit Save and execute yum clean all #清空yum缓存

4. Shielding certain installation packages

Add the following line in the/etc/yum.conf

Exclude *.x86_64 #屏蔽所有64位安装包, don't forget yum clean all clears yum cache
