# installation of software packages:

-rpm

-yum

# rpm package installation

-preparation: download iso image

-Mount the device to a directory: mount xxx.iso / mnt/

-enter the Packages package to execute the command:

Rpm-ivh xxx.rpm # installation software, iinstall, display process

Rpm-qp xxx.rpm # find out the name of the rpm package after it is installed on the system

Rpm-e xxx # remove software

Query:

Rpm-ql xxx.rpm # query which files are generated by the software

Rpm-qc xxx.rpm # query software generated configuration file

Rpm-qa # query the installed software packages

Rpm-qa | grep http # query whether the software related to http is installed

Rpm-qf / bin/ls # check which software package / bin/ls is generated by

-disadvantages: you must change to the directory where the package is located; dependencies need to find their own installation.

# yum installation

-premise

Iso Mirror

Need your software package repository

# # Building a local yum repository

1. Mount the iso image to a local directory:

Mount xxx.iso / mnt/

# you can access the contents of the iso image in the / mnt directory

two。 Tell the yum warehouse where your software is located:

# change to the directory where the yum warehouse configuration file is located

Cd / etc/yum.repos.d/

# Delete the default configuration file when installing the system

Rm-fr *

# Editing your own configuration file

Vim westos.repo # must end with .repo, any before it

`

[rhel7] # Warehouse name

Name=rhel7 # Warehouse description

Baseurl= file:///mnt # warehouse address, file:// is the protocol, / mnt is the local location

Gpgcheck=0 # does not detect key

Enabled=1 # 1, warehouse takes effect; 0, no effect

`

3. Clear the cache:

# by default, you will go to / var/cache/yum to find software information. Be sure to clear the cache after changing the configuration.

Yum clean all

4. Detection

-method 1:

# list the software packages contained in all software repositories

Yum repolist

-method 2:

# install any software at will

Yum install lftp-y

1111111111111111111111111111111111111111111111111111111111111111111111111111111111111111

# # Building Network yum Warehouse

* * desktop host

1. Preparation: make local files accessible to other hosts (httpd)

# generally speaking, hosts with httpd software installed are called Web servers, and files can be shared with other hosts

Yum install httpd-y

Systemctl start httpd

Systemctl enabled httpd

Systemctl stop firewalld

Systemctl disable firewalld

two。 Make the contents of the iso image accessible to other hosts:

# / var/www/html, which is the default release directory for http and accessed by http://ip/rhel7

Mkdir / var/www/html/rhel7

# iso is mounted to the default release directory of http

Mount xxx.iso / var/www/html/rhel7

3. Modify the configuration file of yum repository

# only need to modify baseurl

Vim westos.repo # must end with .repo, any before it

`

[rhel7] # Warehouse name

Name=rhel7 # Warehouse description

Baseurl= http://ip/rhel7 # warehouse address, http:// is the protocol, / rhel7 is the ip host / var/www/html/rhel7 directory

Gpgcheck=0 # does not detect key

Enabled=1 # 1, warehouse takes effect; 0, no effect

`

4. Clear cache and detect

* other hosts (want to use the yum repository built by desktop)

# you only need to modify the configuration file of the yum repository, as in step 3 of desktop

# # Building Network third-Party Software Warehouse

-understand what is third-party software?

The iso image contains more than 4000 software packages, but some software (eg:wps,smplayer,ntfs) does not

Other software packages downloaded from other places (eg:baidu,www.pkgs.org)

* * desktop host

1. Create a software directory for other hosts to access

Mkdir / var/www/html/software

two。 Put the third-party software in the / var/www/html/software directory

# can be accessed at http://ip/software

Cp xxxx.rpm / var/www/html/software/

3. Generate repodata metadata for the software directory to let the system know that there are software packages in that directory

Createrepo / var/www/html/software/

4. Modify the configuration file of yum repository

Vim westos.repo # must end with .repo, any before it

`

[rhel7] # Warehouse name

Name=rhel7 # Warehouse description

Baseurl= http://ip/rhel7 # warehouse address, http:// is the protocol, / rhel7 is the ip host / var/www/html/rhel7 directory

Gpgcheck=0 # does not detect key

Enabled=1 # 1, warehouse takes effect; 0, no effect

[soft] # Warehouse name

Name=soft # Warehouse description

Baseurl= http://ip/software # warehouse address, http:// is the protocol, / software is the ip host / var/www/html/software directory

Gpgcheck=0 # does not detect key

Enabled=1 # 1, warehouse takes effect; 0, no effect

`

5. Clear cache and detect

* other hosts need to use a third-party software repository:

# you only need to modify the configuration file of the yum repository, as in step 4 of the desktop host
