建立自己的Yum源

转自http://kicklinux.com/setup-yum-repos-server/

命令 reposync 可以直接同步yum源

如/etc/yum.repos.d/cloudera-cdh4.repo

合适的目录下 reposync cloudera-cdh4 就ok了

#########更新#################

rhel 5 使用 rhel6 或者 fedora 11 以上版本作为yum 源就会发生如下报错：

[Errno -3] Error performing checksum

原因： rhel 6 中 repomd.xml 文件使用 sha256 作为hash 算法，在rhel 5中默认使用的是sha 作为hash 算法，倒是rhel5 读取 rhel 6 yum 源中的repomd.xml 出现问题

解决办法：将rhel 6 光盘中内容拷贝出来，createrepo -s sha ./ 重新创建repo ，并制定默认算法 sha

##########更新完毕#################

建立自己的yum服务源

为了节省流量，提高效率，我们在机房内部署了自己的yum server。

安装httpd服务。
同步yum源到/var/www/html/linux下的目录

/usr/bin/rsync -avzL --delete--exclude=SRPMS --exclude=i386 --exclude=isos rsync://mirrors.ustc.edu.cn/centos/6/ /var/www/html/linux/centos/x86_64/
/usr/bin/rsync -avzL --delete rsync://mirrors.ustc.edu.cn/fedora-epel/6/x86_64 /var/www/html/linux/centos/epel/

 北京在线源

rsync://mirrors.yun-idc.com/centos
rsync://mirrors.yun-idc.com/epel

官方提供的所有镜像站http://www.centos.org/download/mirrors/

添加自动化任务，每天夜里自动同步

# vi /var/spool/cron/root 

01***/usr/bin/rsync -avzL --delete--exclude=SRPMS --exclude=i386 --exclude=isos rsync://mirrors.ustc.edu.cn/centos/6/ /var/www/html/linux/centos/x86_64/

01***/usr/bin/rsync -avzL --delete rsync://mirrors.ustc.edu.cn/fedora-epel/6/x86_64 /var/www/html/linux/centos/epel/

# service httpd start

在某一台机器上创建和修改以下文件

[root@vm2 yum.repos.d]# more CentOS-Base.repo

测试一下，一切正常。
