在 CentOS 上，可以使用 yum 工具来查询某个包是由哪个仓库提供的。
对于你提到的 python2-pip 包，你可以使用以下命令来查找该包来源的仓库：

# yum list python2-pip

Loaded plugins: fastestmirror, langpacks, versionlock
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Loading mirror speeds from cached hostfile
Excluding 1 update due to versionlock (use "yum versionlock status" to show it)
Installed Packages
python2-pip.noarch                                                 8.1.2-14.el7                                                 @epel

此命令会列出 python2-pip 包的详细信息，并显示该包所在的仓库。

另外，你还可以使用以下命令来查看包的仓库来源：

# yum provides /usr/bin/pip

Loaded plugins: fastestmirror, langpacks, versionlock
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Loading mirror speeds from cached hostfile
Excluding 1 update due to versionlock (use "yum versionlock status" to show it)
python2-pip-8.1.2-14.el7.noarch : A tool for installing and managing Python 2 packages
Repo        : @epel
Matched from:
Filename    : /usr/bin/pip

这个命令会告诉你 /usr/bin/pip 这个文件属于哪个包，及其所在的仓库。

如果你希望更详细的信息，使用 rpm -qi 命令查看已安装包的详细信息，也可以看到仓库的信息，但 yum provides 通常是更直接的方式。
