我们接着上一篇,继续搭建YUM服务

1.挂载光盘镜像

先接着把光盘镜像挂载起来,因为YUM数据仓库的RPM包都要先从安装光盘中拷贝出来

# mount /dev/cdrom /media/
mount: block device /dev/sr0 is write-protected, mounting read-only


2.将光盘中的内容,复制到/var/ftp/pub目录下

/var/ftp/pub目录在vsftp安装完成后,一般会自动生成

# cp -a /media/* /var/ftp/pub/


3.更新数据仓库中的依赖关系,及分组信息

# createrepo -g /var/ftp/pub/repodata/2727fcb43fbe4c1a3588992af8c19e4d97167aee2f6088959221fc285cab6f72-c6-x86_64-comps.xml /var/ftp/pub/

4.启动vsftp并检查监听是否正常

# service vsftpd start
Starting vsftpd for vsftpd:                                [  OK  ]
# netstat -nlptu |grep vsftpd
tcp        0      0 0.0.0.0:21                  0.0.0.0:*                   LISTEN      2806/vsftpd


5.本地登陆,查看是否可以正常看到/var/ftp/pub目录中的内容

# ftp 127.0.0.1

可以看到,一切ok,下面到CentOS2上面配置客户端

2号机上配置客户端与前文所说的配置本地客户端基本一致,只是把basurl的指向改为1号机的ftp

# rename repo repo.bak *
