Linux系统下yum镜像源环境部署记录

之前介绍了Linux环境下本地yum源配置方法,不过这个是最简单最基础的配置,在yum安装的时候可能有些软件包不够齐全,下面说下完整yun镜像源系统环境部署记录(yum源更新脚本下载地址:https://pan.baidu.com/s/1miMNPgc     提取密码:hq6u):

1)安装nginx,用于yum镜像源访问配置
[root@yum ~]# yum -y install gcc pcre-devel zlib-devel openssl-devel
[root@yum ~]# cd /data/software
[root@yum software]# wget http://nginx.org/download/nginx-1.12.0.tar.gz
[root@yum software]# tar -zvxf nginx-1.12.0.tar.gz
[root@yum software]# cd nginx-1.12.0
   
添加www用户,其中-M参数表示不添加用户家目录,-s参数表示指定shell类型
[root@yum nginx-1.12.0]# useradd www -M -s /sbin/nologin
[root@yum nginx-1.12.0]# ./configure --prefix=/data/nginx --user=www --group=www --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre
[root@yum nginx-1.12.0]# make && make install
   
2)配置nginx
[root@yum ~]# cat /data/nginx/conf/vhosts/mirrors.conf
server {
    listen 80;
    server_name yum.kevin.com mirrors.kevin.com localhost;
    index index.html index.php index.htm;
   
    access_log  /data/nginx/logs/access.log main;
    error_log  /data/nginx/logs/error.log;
   
    location / {
    root /data/mirrors;
    autoindex on;
    autoindex_exact_size  off;        
    autoindex_localtime on;
    }
   
  }
   
[root@yum ~]# /data/nginx/sbin/nginx -t
nginx: the configuration file /data/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /data/nginx/conf/nginx.conf test is successful
[root@yum ~]# /data/nginx/sbin/nginx
[root@yum ~]# lsof -i:80
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   7741 root    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7769  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7770  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7771  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7772  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7773  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7774  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7775  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
nginx   7776  www    6u  IPv4  28311      0t0  TCP *:http (LISTEN)
   
   
3)创建yum源数据目录
[root@yum ~]# mkdir -p /data/mirrors
[root@yum ~]# cd /data/mirrors/
[root@yum mirrors]# mkdir centos  epel  etc  rpmforge
[root@yum mirrors]# ls
centos  epel  etc  rpmforge
   
4)编写yum源下载更新脚本(从mirrors.ustc.edu.cn镜像网站下载和更新)
[root@yum ~]# cat /data/script/mirrors.sh
#!/bin/bash
    
#==========================================
# Program   : /bin/update_yum_source.sh
# Info      : 定期同步官方 yum 源到本地
# Version   : 2017.12.10 v1.0
# author    :kevin
# Usage     : 3 3 * * * /bin/bash /data/script/mirrors.sh
#==========================================
    
Date=`date +%Y%m%d`
LogFile="/data/logs/$Date.log"
ReceiveMail="wangshibo@kevin.com"
    
RsyncBin="/usr/bin/rsync"
RsyncPerm="-avrt --delete --exclude=debug/  --exclude=isos/ --exclude=SRPMS/ --exclude=ppc/ --delete-excluded"
    
#============ centos ==============
CentOS_Path="/data/mirrors/centos"
YumSiteList="rsync://mirrors.ustc.edu.cn/centos/"
centosparm="--exclude=2*/ --exclude=3*/ --exclude=4*/ --exclude=5*/"
    
#============ epel ==============
epelSite="rsync://mirrors.ustc.edu.cn/fedora-epel"
epelLocalPath="/data/mirrors/epel"
epelparm="--include=7/x86_64 --include=7Server/x86_64 --include=6/x86_64 --include=6Server/x86_64"
    
#============ rpmforge ==============
rpmforgeSite="rsync://apt.sw.be/pub/freshrpms/pub/dag/redhat/"
#rpmforgeSite="rsync://apt.sw.be/redhat/"
rpmforgeLocalPath="/data/mirrors/rpmforge/"
rpmforgeparm="--exclude=ppc/ --exclude=el2.1/ --exclude=el3/ --exclude=el4/ --exclude=el5/"
    
echo "---- $Date `date +%T` Begin ----" >>$LogFile
    
# centos
$RsyncBin $RsyncPerm  $centosparm $YumSiteList $CentOS_Path >> $LogFile
    
# epel
$RsyncBin $RsyncPerm  $epelparm  $epelSite $epelLocalPath >> $LogFile
    
# rpmforge
$RsyncBin $RsyncPerm  $rpmforgeparm $rpmforgeSite $rpmforgeLocalPath >> $LogFile
    
echo  "---- $Date `date +%T` End ----" >> $LogFile
    
#/bin/mail -s "opt001 - update yum source - $Date" $ReceiveMail<$LogFile
   
   
以上脚本中需要注意的几点:
--exclude   表示rsync同步的时候,需要排除的目录(具体表现:同步下来的目录里面为空,大小为0)
--include   表示rsync同步的时候,只想同步的目录
   
由于本案例是部署yum源,用于linux服务器上本地yum方案安装,不需要同步isos镜像(同时也可以节省机器空间资源),所以在同步的时候将isos镜像目录屏蔽
   
执行同步脚本。这个过程比较长,大概要下载将近180G的内容。需要耐心等待~~
[root@yum ~]# sh -x /data/script/mirrors.sh
   
[root@yum ~]# du -sh /data/mirrors/*
93G   /data/mirrors/centos
80G   /data/mirrors/epel
4.0K  /data/mirrors/etc
4.0K  /data/mirrors/rpmforge
410M  /data/mirrors/software
   
[root@yum ~]# ls /data/mirrors/centos/

5)替换linux本机的yum源地址
[root@yum ~]# cd /etc/yum.repos.d/
[root@yum yum.repos.d]# ls
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Vault.repo
[root@yum yum.repos.d]# mkdir bak
[root@yum yum.repos.d]# mv *.repo bak/
[root@yum yum.repos.d]# ls
bak
   
编写yum源文件
[root@yum yum.repos.d]# cat CentOS-Base.repo
# CentOS-Base.repo
#
# The mirrors system uses the connecting IP address of the client and the
# update status of each mirrors to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrorss.
#
# If the mirrorslist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

[root@yum yum.repos.d]# yum clean all
[root@yum yum.repos.d]# yum makecache
   
   
其他服务器要是想用本yum源,就按照上面操作,将/etc/yum.repos.d目录下的repo文件都移除,然后将上面编写的两个文件放进去,执行yum clean all和yum makecache即可!
   
============================================================================
温馨提示:以上的yum源配置及两个yum文件在centos6和centos7系统下都适用!已经验证!!
   
============================================================================
更新以上yum源的脚本:
可以将上面两个文件放到http://mirrors.kevin.com/software里面,用于脚本中下载
[root@yum ~]# cd /data/mirrors/software/
[root@yum software]# ls
yum_reset.sh        CentOS-Base.repo            epel.repo                    
   
[root@yum software]# cat yum_reset.sh
#!/bin/bash
cd /etc/yum.repos.d/
/bin/mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak
wget http://mirrors.kevin.com/software/CentOS-Base.repo
wget http://mirrors.kevin.com/software/epel.repo
/usr/bin/yum clean all
/usr/bin/yum makecache
   
   
只需要将上面的yum_reset.sh脚本下载到目标服务器上,然后执行,就可以将目标服务器的yum源更新了。
# wget http://mirrors.kevin.com/software/yum_reset.sh
# sh -x yum_reset.sh

  可以定期更新以上的yum源同步脚本(mirros.sh),比如每月更新一次

[root@yum ~]# crontab -e
#每个月1号的23:00点同步一次yum源
0 23 1 * * /bin/bash -x /data/script/mirrors.sh > /dev/null 2>&1
