yum本地源搭建记录

参考：https://www.vos.cn/os/387.html

https://www.wanpeng.life/1903.html

1、安装工具

yum install screen wget -y
yum install yum-utils createrepo -y

2、开始下载

安装源

yum install epel-release -y
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo

查看源列表

yum repolist

image-20230928173702037

创建目录（其实这步可以省，文件夹会自动创建）

mkdir -p /home/html/{base,centosplus,extras,updates}

下载

下载所有，不指定--repoid

reposync -g -l -d -m --newest-only --download-metadata --download_path=/home/html/

下载指定仓库：

reposync -g -l -d -m --repoid=base --newest-only --download-metadata --download_path=/home/html/
reposync -g -l -d -m --repoid=centosplus --newest-only --download-metadata --download_path=/home/html/
reposync -g -l -d -m --repoid=extras --newest-only --download-metadata --download_path=/home/html/
reposync -g -l -d -m --repoid=updates --newest-only --download-metadata --download_path=/home/html/
reposync -g -l -d -m --repoid=epel --newest-only --download-metadata --download_path=/home/html/
reposync -g -l -d -m --repoid=docker-ce-stable --newest-only --download-metadata --download_path=/home/html/

-g 删除公钥校验不通过的包

-d 删除本地有但是远程源没有的包

这两个会导致很多有用的包被删除，比如p7zip、nethogs

3、创建仓库

cd /home/html
ls|xargs -n1 echo createrepo 
# 然后拷贝打印的命令进行执行
# base  docker-ce-stable  epel  extras  updates
#然后压缩
cd ..
tar cJvf html.tar.xz html/
# 或者轻度压缩
tar czvf html.tar.gz html/
# 或者不压缩
tar cvf html.tar html/

4、文件服务器

启动文件服务器

python2（大部分系统自带）

cd /home/html
python -m SimpleHTTPServer 80

python3

cd /home/html
python3 -m http.server 80

5、客户端配置

包含：base docker-ce-stable epel extras updates

[base]
name=base
baseurl=http://192.168.31.197/base
enable=1
gpgcheck=0
proxy=_none_
[docker-ce-stable]
name=docker-ce-stable
baseurl=http://192.168.31.197/docker-ce-stable
enable=1
gpgcheck=0
proxy=_none_
[epel]
name=epel
baseurl=http://192.168.31.197/epel
enable=1
gpgcheck=0
proxy=_none_
[extras]
name=extras
baseurl=http://192.168.31.197/extras
enable=1
gpgcheck=0
proxy=_none_
[updates]
name=updates
baseurl=http://192.168.31.197/updates
enable=1
gpgcheck=0
proxy=_none_

可以用pyhton脚本生成

import os
def gen(name, addr):
    return '''[%s]
name=%s
baseurl=http://%s/%s
enable=1
gpgcheck=0
proxy=_none_

''' % (name,name,addr,name)
if __name__ == "__main__":
    html = "/home/package_dir/html"
    addr = "192.168.31.89"
    content = ""
    for d in os.listdir(html):
        if os.path.isdir(os.path.join(html, d)):
            content += gen(d, addr)
    with open("/etc/yum.repos.d/local.repo", "w") as f:
        f.write(content)

6、优化

6.1、裁剪体积

下载的源中的包，绝大部分是用不到的，可以删除一些，基本上rpm包大小在30M以上的，都可以删除（少数除外），实际操作中，30M以上的，只保留了这几个：

其实这里面有几个也不需要保留

6.2、新增mysql

之前下载的时候没有添加mysql源，后面补上

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
yum install mysql-community-release-el7-5.noarch.rpm
# 重新下载（增量下载）
reposync -l -m --newest-only --download-metadata --download_path=/home/html/
# 重新创建库
cd /home/html
ls|xargs -n1 createrepo

7、定制特定软件的源

yum install screen wget -y
yum install yum-utils createrepo -y
mkdir source
cd source
yumdownloader --resolve --alldeps --destdir=./ docker-ce docker-ce-cli
yumdownloader --resolve --alldeps  --destdir=./ rpcbind 
yumdownloader --resolve --alldeps  --destdir=./ nfs-utils 
yumdownloader --resolve --alldeps  --destdir=./ ipvsadm 
yumdownloader --resolve --alldeps  --destdir=./ ipset 
yumdownloader --resolve --alldeps  --destdir=./ sysstat 
yumdownloader --resolve --alldeps  --destdir=./ conntrack-tools
yumdownloader --resolve --alldeps  --destdir=./ libseccomp

不要一起下载，一起下载时没有对应的源没法下载的包会被忽略。实测，在kylin v10上有 --alldeps选项（下载所有依赖，即使已安装），centos7上没有，所以centos7使用yumdownloader可能会漏包

使用repotrack 参考：https://zhuanlan.zhihu.com/p/662529601

113  repotrack -p ./  docker-ce docker-ce-cli
  118  repotrack -p ./  rpcbind
  119  repotrack -p ./  nfs-utils 
  120  repotrack -p ./  ipvsadm
  121  repotrack -p ./ ipset
  122  repotrack -p ./ sysstat
  123  repotrack -p ./ conntrack
  124  repotrack -p ./ libseccomp
  126  repotrack -p ./ conntrack-tools

创建索引

createrepo ./
tar czvf ../centos7-rpms-amd64.tar.gz ./*
