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/
