搭建本地yum源并定时同步

时间：2021-09-12 21:50:34

在生产中内网的机器都是不能访问外网，所以需要搭建本地yum源。以中国科学科技大学的yum源为基准。http://mirrors.ustc.edu.cn/

有些模块会同步失败，可以wget下载至指定位置。

代码如下： 

#!/bin/bash
#Script name:rsync_yumrepo.sh 

RsyncPerm='-avSH --delete-after --no-iconv --bwlimit=5000'
Centos_6_base='/app/YumRepo/Centos6/x86_64/Base/'
Centos_6_update='/app/YumRepo/Centos6/x86_64/update/'
Centos_6_epel='/app/YumRepo/Centos6/x86_64/Epel'
Centos_6_salt='/app/YumRepo/Centos6/x86_64/Salt'
Centos_6_docker='/app/YumRepo/Centos6/x86_64/Docker'
Centos_7_base='/app/YumRepo/Centos7/x86_64/Base/'
Centos_7_update='/app/YumRepo/Centos7/x86_64/update/'

Centos_7_salt='/app/YumRepo/Centos7/x86_64/Salt'
Centos_7_docker='/app/YumRepo/Centos7/x86_64/Docker'
LogFile='/app/YumRepo/rsync_yum_log'
Date=`date +%Y-%m-%d`

function CheckDir(){
if [ -d $1 ];then
        echo "$1 dir is exist,Please check it!"
else
        echo "$1 dir is not exist,will create it!"
    mkdir $1 -p
fi
}
function CheckFile(){
if [ -e $1 ];then
        echo "$1 dir is exist,Please check it!"
else
        echo "$1 dir is not exist,Please install on there!"
fi
}
function CheckStatus(){
if [ $? -eq 0 ];then
    echo -e "\033[1;32mRsync is success!\033[0m" >>$LogFile/$Date.log
else
    echo -e "\033[1;31mRsync is fail!\033[0m" >>$LogFile/$Date.log
fi
}

同步完成后，启用httpd服务

配置DocumentRoot "/app/YumRepo"

ServerName *:80

<Directory "/app/YumRepo/">

　　Options Indexes FollowSymLinks

　　AllowOverride None

　　Order allow,deny

　　Allow from all

</Dircetory>

检查语法错误httpd -t

重载配置service httpd reload

配置客户端

把/etc/yum.repo.d/目录下的所有.repo文件。mv改为*.bak

新建文件vim /etc/yum.repo.d/CentOS-Base.repo

[base]
name=Centos6 - base
baseurl=baseurl=http://HOSTADDR/Centos6/x86_64/Base
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
 
[updates]
name=CentOS6 - updates
baseurl=http://HOSTADDR/Centos6/x86_64/update
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

重新生成缓存 

　　yum clean all

　　yum makecache
