列出启用的存储库
在 CentOS 6.x 机器上,我有以下存储库:
$ yum repolist|column
Loaded plugins: fastestmirror, priorities, refresh-packagekit
Loading mirror speeds from cached hostfile
* base: mirrors.usinternet.com
* epel: mirror.steadfast.net
* extras: centos.mbni.med.umich.edu
* updates: centos.mirrors.tds.net
76 packages excluded due to repository priority protections
repo id repo name status
base CentOS-6 - Base 6,315+66
epel Extra Packages for Enterprise Linux 6 - x86_64 9,349
extras CentOS-6 - Extras 6+7
updates CentOS-6 - Updates 1,020+3
repolist: 16,690
包 X 来自哪个存储库?
在 CentOS 6.x 上,当我使用命令时,repoquery
我发现以下软件包来自这些存储库:
$ for i in pcre pcre-devel php php-common php-gd php-cli php-mysql flex bison ; do
echo -n $i; repoquery -i --archlist=`uname -m` $i \
| grep Repo | sed 's/Repository//';
done | column -t
产生以下输出:
pcre : base
pcre-devel : base
php : updates
php-common : updates
php-gd : updates
php-cli : updates
php-mysql : updates
flex : base
bison : base

要启用已禁用的存储库之一:
$ yum-config-manager --enablerepo=<reponame>
例如:
$ yum-config-manager --enablerepo=centosplus
添加存储库
如果您有存储库 .repo 文件,您可以添加它并启用它,如下所示:
$ yum-config-manager --add-repo http://www.example.com/example.repo
$ yum-config-manager --enablerepo=example
