yum-utils各个模块的说明

find-repos-of-install 模块

find-repos-of-install 列出包是从哪个yum 仓库安装的。

[root@node1 ~]# find-repos-of-install zlib
Loaded plugins: fastestmirror
zlib-1.2.7-20.el7_9.x86_64 from repo updates   #来着updates仓库
[root@node1 ~]# find-repos-of-install yum-utils

yum-utils-1.1.31-54.el7_8.noarch from repo base  #来着base仓库

　　

needs-restarting　模块

needs-restarting 列出正在允许的进场被更新过，需要重新启动

package-cleanup 模块

package-cleanup列出本地安装的，重复的或者orphan(找不到对应的仓库源)的包

[root@node1 ~]# package-cleanup --problems

repoclosure 模块

repoclosure模块从多个yum仓库读取包的原信息，查询所有的依赖关系，列出无法解决依赖关系的包。

[root@node1 ~]# repoclosure

repo-graph 模块

repo-graph 模块输出一个详细的包依赖关系的列表：输出很多，最好重定向到文本文件上。

[root@node1 ~]# repo-graph --repoid=base |more
"abrt-java-connector" [color="0.682608695652 0.782608695652 1.0"];

"cracklib"
} [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.

按包名查询

show-installed 模块

show-installed 显示已经安装的包和介绍(貌似没什么用)

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-<hostname>-<time>.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'
