在更新 PHP 版本的时候，出现了NOKEY的错误提示后，暂时没有解决掉这个问题，于是就手动安装了php-mbstring...rpm  包的高版本，这样在接下来的错作中就出现了错误信息：The program package-cleanup is found in the yum-utils package. 什么是yum-utils: yum-utils are tools for manipulating repositories and extended package management. It is a collection of tools and programs for managing yum repositories, installing debug packages, source packages, extended information from repositories and administration.  yum-utils package includes: debuginfo-install - install debuginfo packages and their dependencies package-cleanup - manage package cleanup, duplicates, orphaned packages and outstanding dependency problems repo-graph - outputs a full package dependency list in dot format repo-rss - generates an RSS feed from one or more repositories repoclosure - reads metadata of repositories, checks dependencies and displays list of unresolved dependencies repodiff - takes two or more repositories, returns a list of added, removed or changed packages repomanage - manages a directory of rpm packages, returns a list of newest or oldest packages in a directory repoquery - query yum repositories and get additional information on the them reposync - synchronize a remote yum repository to a local directory using yum to retrieve packages repotrack - track packages and its dependencies and downloads them yum-builddep - installs missing dependencies to build a specified package yum-complete-transaction - finds incomplete or aborted yum transactions and attempts to complete them yum-installed - print a compact package list making use of comps groups yumdownloader - downloads packages from yum repositories including source RPMs 出现这句话说明清除程序包存在并在yum-utils套件包里找到了，看不出安装存在问题。存在不兼容问题的话一般是用yum安装一些rpm packages时候会出现missing dependency error，会有error提示的。 解决办法： yum install yum-utils yum-complete-transaction --cleanup-only 清除可能存在的重复包 package-cleanup --dupes 清除可能存在的损坏包 package-cleanup --problems 清除重复包的老版本： package-cleanup --cleandupes package-cleanup 帮助信息如下： options: -h, --help show this help message and exit --problems List dependency problems in the local RPM database --leaves List leaf nodes in the local RPM database --all When listing leaf nodes also list leaf nodes that do not match leaf-regex --leaf-regex=LEAF_REGEX A package name that matches this regular expression (case insensitively) is a leaf --exclude-devel When listing leaf nodes do not list development packages --exclude-bin When listing leaf nodes do not list packages with files in bin dirs --orphans List installed packages which are not available from currenly configured repositories. -q, --quiet Print out nothing unecessary -y Agree to anything asked -d, --dupes Scan for duplicates in your rpmdb --cleandupes Scan for duplicates in your rpmdb and cleans out the older versions --oldkernels Remove old kernel and kernel-devel packages --count=KERNELCOUNT Number of kernel packages to keep on the system (default 2) --keepdevel Do not remove kernel-devel packages when removing kernels -c CONFFILE config file location
