Ubuntu离线源制作

1. 离线制作机操作

1.1 下载软件包及其依赖

cd /var/cache/apt/archives

apt-get download $(apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances vim chrony | grep "^\w" | sort -u)

1.2 构建离线源

mkdir -p /opt/openstackpkg/debs/

touch /opt/openstackpkg/debs/Packages.gz

chmod 777 -R /opt/openstackpkg


# 拷贝离线包到目录
cp -r /var/cache/apt/archives/* /opt/openstackpkg/


# 构建依赖关系
dpkg-scanpackages /opt/openstackpkg /dev/null | gzip > /opt/openstackpkg/debs/Packages.gz


# 打包环境
tar zcvf openstackpkg.tar.gz openstackpkg/

2. 使用离线源

2.1 配置

• 将离线压缩包拷贝到相应机器上解压配置

tar zxvf openstackpkg.tar.gz

cp /etc/apt/sources.list{,.bak}

cat > /etc/apt/sources.list << EOF
deb [trusted=yes] file:// /opt/openstackpkg/debs/
EOF

apt-get clean all
apt-get update
