目录

Linux local source list

A. Ubuntu

1. 本地ISO

# 首先挂载本地镜像
mount -o loop -t iso9660 ./ubuntu.iso /media/cdrom
# 手动添加ISO镜像至源列表，这样就可以在软件库中找到ISO中的所有包
apt-cdrom -m -d=/media/cdrom add
# 刷新软件库
apt update
# 完成后查看sources.list ，本地源应该在第一条，否则默认还是从网上下载

e.g.

root@ubuntu:/# mount -t iso9660 /dev/cdrom /media/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
root@ubuntu:/# sudo apt-cdrom -m -d /media/cdrom/ add
Using CD-ROM mount point /media/cdrom/

Writing new source list
Source list entries for this disc are:
deb cdrom:[Ubuntu-Server 16.04.5 LTS _Xenial Xerus_ - Release amd64 (20180731)]/ xenial main restricted
Repeat this process for the rest of the CDs in your set.
root@ubuntu:/# vim /etc/apt/sources.list
# 此时sources.list中多出一行本地源
# deb cdrom:[Ubuntu-Server 16.04.5 LTS _Xenial Xerus_ - Release amd64 (20180731)]/ xenial main restricted

root@ubuntu:/# 
root@ubuntu:/# sudo apt update

2. 制作本地源

平时apt-get install安装软件时，下载的deb文件都会存放在/var/cache/apt/archives/下，为了今后重装或给别人用 。

步骤：

# 新建离线源目录
mkdir ~/packs
# 将缓存复制到目录
cp -rv  /var/cache/apt/archives/* ~/packs

    # 拷贝过来发现在packs当中为文件都是root账户的，需要修改
    # 修改所有者
    # sudo chown -R someone.someone * $pack_dir
    # 修改权限
    # sudo chmod ug+rw,o+r * $pack_dir
    
# 建立Packages包，里面记录了packs目录下的软件包信息，包括依赖信息
dpkg-scanpackages ~/packs /dev/null |gzip > packs/Packages.gz -r
# 将~/packs复制到目标计算机，或本机的某处
vim /etc/apt/sources.list
# 添加 deb file:/// /home/someone/packs/ 
# 注意： packs后面有一个斜杠，全路径前面还要有空格
# 更新源
sudo apt-get update ---allow-insecure-repositories
sudo apt-get install -f
sudo apt-get xxxx --allow-unauthenticated
# 本地的源是没有签名的，直接更新ubuntu1604下的apt会提示找不到release文件，是一种不安全的源，默认是被禁用的。如果还要安装的话需要加上 --allow-unauthenticated 选项。
# N: Updating from such a repository can't be done securely, and is therefore disabled by default.

B. CentOS

1. 本地ISO

1. 首先创建挂载点
2. 然后挂载光驱
3. 移除原有源
4. 新建local.repo文件,内容如下：
​```
[name]
name="local repo"
baseurl=file:///media/cdrom/
enabeld=1
gpgcheck=0
​```
5. 对yum进行初始化操作

e.g.

[root@cent7 ~]# mkdir /media/cdrom
[root@cent7 ~]# mount -t iso9660 /dev/cdrom /media/cdrom
mount: /dev/sr0 is write-protected, mounting read-only
[root@cent7 ~]# cd /etc/yum.repos.d/
[root@cent7 yum.repos.d]# pwd
/etc/yum.repos.d
[root@cent7 yum.repos.d]# ls
CentOS-Base.repo  CentOS-Base.repo.bak  CentOS-CR.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Sources.repo  CentOS-Vault.repo  epel.repo  epel-testing.repo  mysql-community.repo  mysql-community-source.repo
[root@cent7 yum.repos.d]# mkdir bak
[root@cent7 yum.repos.d]# mv *.repo bak/
[root@cent7 yum.repos.d]# vim local.repo
写入以下内容：
        [name]
        name="local repo"
        baseurl=file:///media/cdrom/
        enabeld=1
        gpgcheck=0

[root@cent7 yum.repos.d]# yum clean all  # 清除缓存

Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

[root@cent7 yum.repos.d]# yum makecache  # 建立新缓存
Loaded plugins: fastestmirror
