How to use showduplicates in yum command
This article introduces the relevant knowledge of "the use of showduplicates in the yum command". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Yum has a lot of parameters and plug-ins available, so here I'll show you how to use the yum-showduplicates command, which is very useful for us. Especially if you encounter version mismatch compatibility and software dependency problems, you can use this command to find the software version you want.
Assuming that you need to find a specific version of pcre for php, type:
The code is as follows:
# yum search-showduplicates pcre
The keyword pcre will be used to search the yum source for matching software packages.
Output:
The code is as follows:
Loaded plugins: fastestmirror, versionlock
Loading mirror speeds from cached hostfile
* base: mirrors.usc.edu
* extras: mirror.web-ster.com
* updates: mirror.hmc.edu
Reading version lock configuration
= = Matched: pcre = =
Pcre-6.6-9.el5.i386: Perl-compatible regular expression library
Pcre-6.6-9.el5.i386: Perl-compatible regular expression library
Pcre-devel-6.6-9.el5.i386: Development files for pcre
According to the output information, find the full name of the version you want, and then install it with yum
Of course, this uses yum search-showduplicates to output so many packages that if the goal is not clear, it is impossible to determine which package we can use. So you can use the following command:
The code is as follows:
# yum-showduplicates list php-gd
Output:
The code is as follows:
Loaded plugins: fastestmirror, versionlock
Loading mirror speeds from cached hostfile
