CentOS7搭建本地YUM仓库并定期同步阿里云源

1、CentOS7搭建本地YUM仓库，并定期同步阿里云源 阅读目录· CentOS7同步阿里云镜像rpm包并自建本地yum仓库o 系统环境o 安装相关软件o 根据源标识同步源到本地目录 回到顶部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-releaseCentOS Linux release 7.6.1810 (Core)# uname -r3.10.0-957.el7.x86_64# ip a |awk 'NR=9print $2'|awk -F '/' 'print $1'

2、;00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 # wget -O /etc/yum.repos.d/epel.repo 或者# curl -o /etc/yum.repos.d/CentOS-Base.repo # curl -o /etc/yum.repos.d/epel.repo  检验阿里云源是否正常# yum repolistLoaded plugin

18、m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  

19、60;  #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/

20、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/bashecho 'Updating Aliyum Source'DATETIME=date +%F_%Texec > /var/log/aliyumrepo_$DATETIME.log     re

21、posync -np /mirrorif $? -eq 0 ;then      createrepo -update /mirror/base      createrepo -update /mirror/extras      createrepo -update /mirror/updates      createrepo -update /mirror/epel  

22、  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 Source00 13 * * 6 $(date +%d) -eq $(cal | awk 'NR=3print $NF') && /bin/bash /

23、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源创建运行账户groupadd nginxuseradd -r -g nginx -s /bin/false -M nginx# yum install nginx -y找到nginx配置文件，并修改nginx配置文件：# vim nginx.confworker_processes  1;events     worker_connections  1024;http
