RPM (Original: RedHat Package Manager now means: RPM is the package manager)

(Package, install, uninstall, upgrade, query, check)

2.RPM Package Acquisition Method

1, release version self-provided package

2,fedora-epel

3, the official site of the project

4, search engine

Http://rpmfind.net

Http://rpm.pbone.net

http://pkgs.org

5, Mount device file acquisition

3.RPM (package, install, uninstall, upgrade, query, check)

RPM-IVH xxx.rpm	Install a package-i:install-v: Show installation Process-H: Show installation progress in #
RPM-UVH xxx.rpm	Upgrade a package-u:upgrade if there is an older version of the package, upgrade it, or if not, install it;
RPM-FVH xxx.rpm	Remove a package-f:freshen if there is an older version of the package, upgrade it, or if not, install it;
Rpm-e xxx.rpm	Removing a package-e:erase
Rpm-qa	Query the current machine on all installed RPM packages-q:query-a:all
Rpm-q xxx	Query if XXX package exists
Rpm-qf	Query which package the file is generated by
Rpm-qc	Queries the specified package installation build configuration file
Rpm-qd	Query the specified package installation build document
Rpm-qi	Querying for information about a specified package
Rpm-ql	Query the list of all files generated by the specified package installation
Rpm-v	Verifies whether the current file has been changed

4. Package Check:

1, local key address:/ETC/PKI/RPM-GPG

[Email protected] yum.repos.d]# ll/etc/pki/rpm-gpg/-rw-r--r--. 1 root root 1706 October rpm-gpg-key-centos-6-rw-r--r--. 1 root root 1730 October rpm-gpg-key-centos-debug-6-rw-r--r--. 1 root root 1730 October rpm-gpg-key-centos-security-6-rw-r--r--. 1 root root 1734 October rpm-gpg-key-centos-testing-6

2, import the local key: Rpm-import/etc/pki/rpm-gpg/keyfile

[Email protected] yum.repos.d]# rpm--import/etc/pki/rpm-gpg/rpm-gpg-key-centos-6

3, RPM package check: Rpm-k/rmpfile

[Email protected] software]# rpm-k mysql-server-5.5.36-1.el6.x86_64.rpm MYSQL-SERVER-5.5.36-1.EL6.X86_64.RPM:SHA1 MD5 (GPG) not OK (MISSING keys:gpg#5072e1f5)
