搭建CentOS在线yum源镜像服务器

准备篇：

一、安装http服务器

二、系统约定

三、开始Nginx目录浏览功能

# vi /usr/local/nginx/conf/nginx.conf #编辑配置文件，在http {下面添加以下内容：

  autoindex on; #开启nginx目录浏览功能

  autoindex_exact_size off; #文件大小从KB开始显示

  autoindex_localtime on; #显示文件修改时间为服务器本地时间

:wq! #保存，退出

# service nginx reload #重新加载配置

参考：Nginx开启目录浏览功能: http://www.osyunwei.com/archives/5051.html

安装篇：

一、创建镜像文件存放目录

mkdir -p /usr/local/nginx/html/centos #CentOS官方标准源

mkdir -p /usr/local/nginx/html/repoforge #第三方rpmforge源

mkdir -p /usr/local/nginx/html/epel #第三方epel源

说明：这里创建三个文件夹，分别存放CentOS官方标准源、第三方的rpmforge源和epel源

二、确定以上三个yum源上游源的同步镜像地址

三、创建以上三个yum源同步脚本，并且设定脚本自动执行

# mkdir -p /home/crontab #创建目录
# vi /home/crontab/yum_rsync.sh #添加以下代码
  #!/bin/sh

 /usr/bin/rsync -avrt rsync://mirrors.ustc.edu.cn/centos/ --exclude-from=/usr/local/nginx/html/exclude_centos.list /usr/local/nginx/html/centos/

 /usr/bin/rsync -avrt rsync://mirrors.ispros.com.bd/repoforge/ --exclude-from=/usr/local/nginx/html/exclude_repoforge.list /usr/local/nginx/html/repoforge/

 /usr/bin/rsync -avrt rsync://mirrors.ustc.edu.cn/epel/ --exclude-from=/usr/local/nginx/html/exclude_epel.list /usr/local/nginx/html/epel/

:wq! #保存退出

chmod +x /home/crontab/yum_rsync.sh #添加脚本执行权限

备注：运行此脚本前，先要创建好同步目录及不需要同步的目录列表文件

# cd /usr/local/nginx/html/   #进入目录
# touch exclude_centos.list   #创建文件
# touch exclude_repoforge.list   #创建文件
# touch exclude_epel.list   #创建文件

把不需要同步的目录写到上面对应的文件中，每行一个目录,例如：

# vi exclude_epel.list

# 4/
# 4AS/
# 4ES/
# 4WS/

:wq! #保存退出

四、添加脚本定时执行任务

# vi /etc/crontab  #在最后一行添加以下代码

 0 1 * * * root /home/crontab/yum_rsync.sh #设置每天凌晨1点整开始执行脚本

:wq! #保存退出

# service crond restart #重启

测试篇：

一、安装rsync同步软件

# yum install rsync xinetd #安装

# vi /etc/xinetd.d/rsync #编辑配置文件，设置开机启动rsync

 disable = no #修改为

# /etc/init.d/xinetd start #启动（CentOS中是以xinetd 来管理Rsync服务的）

:wq! #保存退出

二、执行同步脚本

# sh /home/crontab/yum_rsync.sh

注意：等待脚本执行完毕，首次同步，耗费的时间比较长！

三、根据不同版本创建三个yum源的repo配置文件

# cd /etc/yum.repos.d/ #进入目录
# mv /etc/yum.repos.d/CentOS-Base.repo CentOS-Base.repo-bak

  1. CentOS官方标准源：

  2. rpmforge源：

  3. epel源：

四、测试yum源是否配置正确

当前系统版本为CentOS 6.x，以此为例

  1. 添加CentOS-Base.repo

    # cd /etc/yum.repos.d/
# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
# vi CentOS-Base.repo #添加以下代码

  # CentOS-Base.repo

  #

  # The mirror system uses the connecting IP address of the client and the

  # update status of each mirror 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 mirrors.

  #

  # If the mirrorlist= does not work for you, as a fall back you can try the

  # remarked out baseurl= line instead.

  #

  #

    # vi rpmforge.repo #添加以下代码

 [rpmforge]

 name = RHEL $releasever - RPMforge.net - dag

 baseurl = http://192.168.21.188/repoforge/redhat/el6/en/$basearch/rpmforge

 enabled = 1

 gpgkey=http://192.168.21.188/repoforge/RPM-GPG-KEY-rpmforge

 gpgcheck = 1

    :wq! #保存退出

  3. 添加epel.repo

    # vi epel.repo #添加以下代码

 [epel]

 name=Extra Packages for Enterprise Linux 6 - $basearch

 baseurl=http://192.168.21.188/epel/6/$basearch

 failovermethod=priority

 enabled=1

 gpgcheck=1

 gpgkey =http://192.168.21.188/epel/RPM-GPG-KEY-EPEL-6

  4. 清除缓存，列出可用源软件包

    # yum clean all #清除当前yum缓存
# yum makecache #缓存yum源中的软件包信息
# yum repolist #列出yum源中可用的软件包
  5. 使用yum命令安装软件
    # yum install php #测试CentOS官方标准源
# yum install htop #测试rpmforge源
# yum install nginx #测试epel源

至此，搭建CentOS在线yum源镜像服务器完成
