建立本地yum源

使用环境

• 服务器处于内网,需要更新
• 网络资源紧张,节约带宽

建立yum目录

mkdir -p /opt/opmgmt/yum

rsync服务器列表

• centos mirrors
• epel mirrors
• rpmforge mirrors

同步脚本

/opt/opmgmt/yum/rsync_centos.sh

#!/bin/bash
repo_root='/opt/opmgmt/yum/centos/'
sync_cmd='rsync -arv --delete-after --delete-excluded'
sync_srv='rsync://mirrors.shu.edu.cn/centos/'
exclude='--exclude [23456]/ --exclude [2345].*/ --exclude i386/ --exclude drpms/ --exclude SCL/ --exclude centosplus/ --exclude contrib/ --exclude cr/ --exclude fasttrack/ --exclude isos/ --exclude virt/ --exclude paas/ --exclude 7.[012]*/ --exclude atomic/ --exclude cloud/ --exclude storage/'

[ -d $repo_root ] && mkdir -p $repo_root 
$sync_cmd $exclude $sync_srv $repo_root &

/opt/opmgmt/yum/rsync_epel.sh

#!/bin/bash
repo_root='/opt/opmgmt/yum/epel/'
sync_cmd='rsync -arv --delete-after --delete-excluded'
sync_srv='rsync://mirrors.shu.edu.cn/epel/'
exclude='--exclude [45]*/ --exclude testing/ --exclude SRPMS/ --exclude i386/ --exclude ppc64*/ --exclude aarch64/ --exclude debug/ --exclude=repoview'

[ -d $repo_root ] && mkdir -p $repo_root 
$sync_cmd $exclude $sync_srv $repo_root &

cd yum
rsync -avzRHP --delete-after --exclude={'debug/','drpms/'} rsync://hkg.mirror.rackspace.com/epel/7/x86_64/ epel/
rsync -avzRHP --delete-after --exclude={'atomic/','cr/','dotnet/','fasttrack/','isos/','nfv/','opstools/','rt/'} rsync://hkg.mirror.rackspace.com/centos/7/ centos/

计划任务

/etc/cron.d/sync-yum-repo

0 1 * * * root /bin/sh /opt/opmgmt/yum/rsync_centos.sh
0 2 * * * root /bin/sh /opt/opmgmt/yum/rsync_epel.sh

自定义源

yum install createrepo
mkdir -p /opt/opmgmt/yum/custom/x86_64
copy *rpm /opt/opmgmt/yum/custom/x86_64
createrepo -p -d --update /opt/opmgmt/yum/custom/x86_64

nginx服务配置

/etc/nginx/conf.d/yum.conf

server {
    listen	192.168.0.100:80;
    server_name	yum.localhost;

    #allow 10.0.1.0/24;
    #deny all;

    charset utf-8;
    access_log  /var/log/nginx/$server_name.access.log  main;

    location / {
        root   /opt/www/yum;
        index  index.html index.htm;
    }

    error_page  404              /404.html;
    location = /404.html {
        root   /usr/share/nginx/html;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}
