Question

我们正在使用运行Angstrom Linux的BeagleBone Black和opkg软件包管理器为我们的某些系统供电。我们需要确保我们对opkg软件包的特定版本具有一致且可靠的访问权限。我已经建立了一个内部opkg存储库。有没有办法在存储库之间同步包？例如我希望将特定软件包从公共/不可访问的存储库复制到我们的内部存储库，以实现速度和可靠访问。

在使用各种软件包之后，我发现了一种使用Ubuntu系统克隆（部分）存储库的方法。这是我采取的步骤：

# Install apache
sudo apt-get install apache2

# Install git
sudo apt-get install git

# Download the opkg-utils from the Yocto Project
git clone http://git.yoctoproject.org/git/opkg-utils

# Build the opkg-utils
cd opkg-utils && make; cd -

# Move them to a common directory
mv opkg-utils /usr/local/share\

# Add them to my path
echo "PATH=\"\$PATH:/usr/local/share/opkg-utils\"" >> /etc/environment

# Update my environment
source /etc/environment

# Create the structure of my repository
mkdir -p /var/www/repositories/opkg/beaglebone

# Create an index for the packages
opkg-make-index -l Packages.filelist -p Packages /var/www/repositories/opkg/beaglebone
cd /var/www/repositories/opkg/beaglebone
gzip -c Packages > Packages.gz

在我的客户端BeagleBone Blacks上，设置对此存储库的访问权限：

echo "src/gz reponame http://myserver/repositories/opkg/beaglebone" > /etc/opkg/rms-feed.conf
chmod 666 /etc/opkg/reponame-feed.conf
opkg update

在我的开发者计算机上，任何时候我需要备份包：

# bbb_clone_package_to_internal_repo.sh
#
# Description:
# Clones an ipkg / opkg package to the internal repository server so that it can be deployed 
# to BeagleBone Black clients on demand. This is so that we can have backups in
# the event that a public server becomes temporarily or permanently 
# inaccessible.
#
# Pre-conditions:
# 1) The given package file must exist at the path specified. 
#
# Post-conditions:
# 1) The given package file will be sent to the internal repository server.
# 2) The opkg repository indexes will all be updated 
#
# Parameters:
# -p <file path.opk> : The package to be cloned

exit 0

与opkg打包同步
