Cloud Computing Learning Route course syllabus Courseware: use RPM tools to manage RPM packages:

=

Need to consider:

OS version, e.g. Centos6/7 # cat / etc/redhat-release

System architecture, e.g. I386/x86_64 # uname-m

Dependency, e.g. Ntfs-3g-devel needs to rely on ntfs-3g

Version of the rpm package, e.g. 2015 and 2017

= = install

Rpm-ivh local_path

Rpm-ivh url_path

[root@tianyun ~] # rpm-ivh ntfs-3g-2017.3.23-1.el7.x86_64.rpm package name

[root@tianyun ~] # rpm-Uvh ntfs-3g-2017.3.23-1.el7.x86_64.rpm package name

[root@tianyun ~] # rpm-ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/n/ntfs-3g-devel-2017.3.23-1.el7.x86_64.rpm

Additional options:

-- nosignature / / does not verify the signature of the software package

-- force / / forced installation of the software package yum reinstall

-- nodeps / / ignore dependencies

Software uninstall

# rpm-e Software name

-e erase

-- force is used during installation (force override installation)

-- nodeps is used when uninstalling (dependencies are not checked when uninstalling)

The RPM package installation information is stored in the local RPM database.

= = query

(from the local rpm database)

[root@tianyun ~] # rpm-Q ntfs-3g / / query whether the specified package is installed

[root@tianyun ~] # rpm-qa | grep ntfs

[root@tianyun ~] # rpm-ql ntfs-3g / / query the files installed by ntfs-3g

[root@tianyun ~] # rpm-qf / usr/bin/ntfs-3g / / query which rpm package the file belongs to

[root@tianyun ~] # rpm-qi ntfs-3g / / query package information

[root@tianyun ~] # rpm-qc ntfs-3g / / query the configuration file installed by a package

[root@tianyun ~] # rpm-qd vsftpd / / check the installation help documentation

= = Uninstall

[root@tianyun] # rpm-e ntfs-3g

[root@tianyun] # rpm-e ntfs-3g-- nodeps! Uninstall directly without detecting dependencies

Case 3: install the following software packages

Vsftpd

Samba

Nfs-utils

Httpd

Dhcp

Postfix

Mysql-server

Php

Lftp

Dos2unix

Unix2dos

Tigervnc

[root@tianyun Packages] # pwd

/ media/cd/Packages

[root@tianyun Packages] # rpm-ivh samba-3.0.33-3.37.el5.i386.rpm samba-common-3.0.33-3.37.el5.i386.rpm

Summary of the rpm tool management package:

It is difficult to solve package dependencies

If a file does not exist, it is difficult to know which rpm package provides it, for example, which package provides the semanage or tree commands?

Remote copy

[root@test tmp] # scp / tmp/aa.txt 172.16.110.1:/tmp/

[root@robin ~] # scp / root/install.log 172.16.110.30:/tmp/

[root@robin ~] # scp 172.16.110.30:/tmp/aa.txt 172.16.110.40:/tmp/
