只下载rpm安装包而不进行安装:

安装插件yum-plugin-downloadonly:

[root@saltstack zhongw]yum install yum-plugin-downloadonly

将tcpdump包下载到目录/zhongw下面:

[root@saltstack zhongw]# yum install --downloadonly --downloaddir=/zhongw/ tcpdump

本地网络yum源配置:

新建并修改yum配置文件:

vi  /etc/yum.repos.d/rh6.7.repo

[base]

Baseurl=http://192.168.1.10/rh6.7/

Gpgcheck=0

Enable=1

cat > /etc/yum.repos.d/rh6.7.repo <<EOF

[base]

Baseurl=http://192.168.1.10/rh6.7/

Gpgcheck=0

Enable=1

EOF


本地yum:

例如:

mount /dev/cdrom /mnt/

cat > /etc/yum.repos.d/local.repo <<EOF

[base] #库名称

name=Centos6.5_local   #名称描

Baseurl=file:///mnt/   #yum源目录,源地址

Gpgcheck=0   #检查GPG-KEY,0为不检查,1为检查

Enable=1   #是否用该yum源,0为禁用,1为使用

EOF


测试yum:

yum list
