CentOS7同步阿里云镜像rpm包并自建本地yum仓库
系统环境
# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
# uname -r
3.10.0-957.el7.x86_64
# ip a |awk ‘NR==9{print $2}‘|awk -F ‘/‘ ‘{print $1}‘
10.0.0.100
修改yum源为阿里云源
备份系统自带的yum源
# tar -zcvf CentOS-bk.tar.gz /etc/yum.repos.d/CentOS-*
修改yum源
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
或者
# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
检验阿里云源是否正常
# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
#仓库标识仓库名称状态
repo id repo name status
!base/7/x86_64 CentOS-7 - Base - mirrors.aliyun.com 10,019
!epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 12,902
!extras/7/x86_64 CentOS-7 - Extras - mirrors.aliyun.com 371
!updates/7/x86_64 CentOS-7 - Updates - mirrors.aliyun.com 1,103
repolist: 24,395
安装相关软件
# yum install -y wget make cmake gcc gcc-c++ pcre-devel lib zlib-devel openssl openssl-devel createrepo yum-util
yum-utils:reposync同步工具
createrepo:编辑yum库工具
plugin-priorities:控制yum源更新优先级工具,这个工具可以用来控制进行yum源检索的先后顺序,建议可以用在client端。
注:由于很多人喜欢最小化安装,上边软件是一些常用环境。
根据源标识同步源到本地目录
创建本地目录
#mkdir /mirror
同步到本地目录
# reposync -p / mirror
注:不用担心没有创建相关目录,系统自动创建相关目录,并下载,时间较长请耐心等待。
可以用 repo -r --repoid=repoid指定要查询的repo id,可以指定多个(# reposync -r base -p /mirror #这里同步base目录到本地)
更新新的rpm包
# reposync -np /mirror
注:时间同样较长,请耐心等待。
创建索引
# createrepo -po /mirror/base/ /mirror/base/
# createrepo -po /mirror/extras/ /mirror/extras/
# createrepo -po /mirror/updates/ /mirror/updates/
# createrepo -po /mirror/epel/ /mirror/epel/
更新源数据
# createrepo --update /mirror/base
# createrepo --update /mirror/extras
# createrepo --update /mirror/updates
# createrepo --update /mirror/epel
创建定时任务脚本
#vim /mirror/script/centos_yum_update.sh
#!/bin/bash
echo ‘Updating Aliyum Source‘
DATETIME=`date +%F_%T`
exec > /var/log/aliyumrepo_$DATETIME.log
reposync -np /mirror
if [ $? -eq 0 ];then
createrepo --update /mirror/base
createrepo --update /mirror/extras
createrepo --update /mirror/updates
createrepo --update /mirror/epel
echo "SUCESS: $DATETIME aliyum_yum update successful"
else
echo "ERROR: $DATETIME aliyum_yum update failed"
fi
将脚本加入到定时任务中
# crontab -e
# Updating Aliyum Source
00 13 * * 6 [ $(date +%d) -eq $(cal | awk ‘NR==3{print $NF}‘) ] && /bin/bash /mirror/script/centos_yum_update.sh
每月第一个周六的13点更新阿里云yum源
安装nginx开启目录权限保证本地机器可以直接本地yum源
# yum install nginx -y
找到nginx配置文件,并修改nginx配置文件:
# vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
root /mirror ; #这里是yum源存放目录
location / {
autoindex on; #打开目录浏览功能
autoindex_exact_size off; # off:以可读的方式显示文件大小
autoindex_localtime on; # on、off:是否以服务器的文件时间作为显示的时间
charset utf-8,gbk; #展示中文文件名
index index.html;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
在客户端修改yum源,并指向本地搭建的yum源主机
