yum-utils 详解

yum-utils是yum的工具包集合，由不同的作者开发，使yum使用起来更加方便和强大。包括：debuginfo-install,find-repos-of-install, needs-restarting, package-cleanup, repoclosure, epodiff, repo-graph, repomanage, repoquery, repo-rss, reposync,: repotrack, show-installed, show-changed-rco, verifytree, yumdownloader, yum-builddep,yum-complete-transaction, yum-config-manager, yum-debug-dump, yum-debug-restore and yum-groups-manager.

命令：yum install yum-utils -y

} [color="0.604347826087 0.704347826087 1.0"];

}

repomanage 模块

repomanage 在指定目录后，列出最新和最旧的包

[root@node1 ~]# repomanage --old ./
[root@node1 ~]# repomanage --new ./
mysql80-community-release-el7-6.noarch.rpm
rsyslog-8.2206.0-1.el8.x86_64.rpm

repoquery 模块

类似于yum info /list /provides以及rpm的集合。功能强大.

[root@node1 ~]# repoquery zlib
zlib-0:1.2.7-20.el7_9.i686
zlib-0:1.2.7-20.el7_9.x86_64

#repoquery -i 类似于rpm -qi
[root@node1 ~]# repoquery -i zlib

reposync 模块

reposync 将yum仓库同步到本地目录。后续可以自己做yum仓库

#Sync all packages from the 'updates' repo to the repos directory:
reposync -p repos --repoid=updates

Sync all packages from the 'updates' repo to the repos directory excluding x86_64 arch. Edit /etc/yum.conf adding option exclude=*.x86_64. Then:

reposync -p repos --repoid=updates

repotrack 模块

repotrack 调查一个包，和他的依赖关系，并下载下来，可以作为reposync的补充使用。

yum-debug-dump/yum-debug-restore 模块

yum-debug-dump模块是用来导出当前安装的和仓库源里可安装的rpm包信息。dump会输出一个文件在当前目录：yum_debug_dump--.txt.gz。可以用zless命令命令查看

yun-debug-restore导入dump模块输出的txt.gz的包到本地信息库

yum-groups-manager

EXAMPLES
Create a new group metadata file, with a group called yum containing all the packages that start with yum:
yum-groups-manager --name YUM --save groups.xml 'yum*'

   After the above command, load the groups.xml data, work with the yum group, make the group not user visible, and remove the yum-skip-broken and yum-priorities packages from it:  
           yum-groups-manager -n YUM --merge groups.xml --remove yum-skip-broken yum-priorities --not-user-visible

   After the above commands, add a description and a translated name to the yum group:  
           yum-groups-manager -n YUM --merge groups.xml --description 'This is a group with most of the yum packages in it' --translated-name 'en:yum packages'
