如何更新 YUM 存储库？

Question

我对这一切都非常非常陌生，所以如果对您的帮助表示赞赏，请采取婴儿步骤。

我正在尝试连接到以下存储库，以便我可以更新我的 YUM 包：http : //repo.webtatic.com/yum/centos/5/SRPMS/

老实说，我不知道如何从 SSH 中做到这一点 - 任何指导都非常感谢。

Answer 1

说明在：http : //www.webtatic.com/projects/yum-repository/

rpm -ivh http://repo.webtatic.com/yum/centos/5/`uname -i`/webtatic-release-5-0.noarch.rpm

Answer 2

首先，您必须在 yum 的配置文件中设置存储库。像这样创建存储库配置：

# cd /etc/yum.repos.d
# nano Webtatic

在文件中插入类似这样的内容

[webtatic] 
name=Webtatic repo
baseurl=http://repo.webtatic.com/yum/centos/5/SRPMS/
enabled=1 
gpgcheck=1 
gpgkey=http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy

保存并关闭文件。然后导入存储库的密钥：

# rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy

此时存储库已添加到 yum 中。现在你只需要使用它。

# yum update

yum 干净的元数据

取自“man yum”？干净

CLEAN OPTIONS

  yum clean expire-cache
         Eliminate  the local data saying when the metadata and mirrorlists were downloaded for each repo. This means yum will revalidate the cache for each repo. next time it is used. However if the cache is still valid, nothing significant was deleted.

  yum clean packages
         Eliminate any cached packages from the system.  Note that packages are not automatically deleted after they are downloaded.

  yum clean headers
         Eliminate all of the header files, which old versions of yum used for dependency resolution.

  yum clean metadata
         Eliminate all of the files which yum uses to determine the remote availability of packages. Using this option will force yum to download all the metadata the next time it is run.

  yum clean dbcache
         Eliminate the sqlite cache used for faster access to metadata.  Using this option will force yum to download the sqlite metadata the next time it is run, or recreate the sqlite  metadata  if using an older repo.

  yum clean rpmdb
         Eliminate any cached data from the local rpmdb.

  yum clean plugins
         Tell any enabled plugins to eliminate their cached data.

  yum clean all
         Does  all  of  the  above.  As a convenience, if this command does not result in a completely empty cache due to the restrictions outlined at the beginning of this section, a message will be printed, saying how much disk space can be reclaimed by cleaning the remaining repos manually.  For this purpose, a repo is considered clean when its disk usage doesn't exceed 64KB (that  is to account for directory entries and tiny metadata files such as "productid" that are never cleaned).
