<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'><strong>一、yum环境的本地源搭建(基于VSFTP)：</strong><br><br>
1）安装vsftp;<br>
******************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
# mount /dev/hdc /mnt<br>
# cd /mnt/Server/<br>
# ls |grep vsftp<br>
vsftpd-2.0.5-12.el5.i386.rpm<br>
# rpm --import /etc/pki/rpm-pgp/RPM- PGP-KEY-redhat-release<br>
# rpm -ivh vsftpd-2.0.5-12.el5.i386.rpm <br>
# chkconfig vsftpd on <font color="#ff0000">//开启计算机自动运行vsftpd服务</font><br>
# service vsftpd restart <br>

2）将安装光盘中的文件全部移动到/var/ftp/pub目录下；<br>
3）安装createrepo并创建相关yum库文件:<br>
*****************************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
# ls |grep create<br>
createrepo-0.4.11-3.el5.noarch.rpm<br>
# rpm -ivh createrepo-0.4.11-3.el5.noarch.rpm<br>
# createrepo -v /var/ftp/pub <font color="#ff0000">//打完命令等待一会就会处理完</font><br>
*****************************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
4）编辑/etc/yum.conf文件；加入如下内容：<br>
vim /etc/yum.conf<br>
******************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
（名字可以随便写）<br>
name=yumok（名字可以随便写和上面相同）<br>
baseurl=ftp://192.168.1.88/pub/Server（填写本地的IP地址及相关路径，这里的根是/var/ftp/ ；如果YUM服务器不是本机对应的修改这个地址就可以）<br>
enabled=1<br>
gpgcheck=1</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
********************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
5）测试yum一；例如我们安装gcc<br>
Yum list| grep gcc*；列出相关的yum源。<br>
Yum install gcc.i386 ；yum相关关包源文件的结尾都是.i386<br>
6）yum安装的包源的卸载；<br>
Yum remove gcc ；在卸载包源的时候只会卸载指定的包，安装是需要同步安装的包一般不会删除。<br>
备注：如果在用yum list命令查看列表时出现不能查看被防火前屏蔽的问题<br>
1)防火墙的问题：打开20:21端口： vim /etc/sysconf/iptables<br>
************************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
……前面省略<br>
-A RH-Firewall-1-INPUT -p tcp —dport 20:21 -j ACCEPT<br>
-A RH-Firewall-1-INPUT -p udp —dport 20:21 -j ACCEPT<br>
……后面省略 增加上上面这两行</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
***********************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
2)selinux的问题：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
************************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
setsebool -P -ftpd_disable_trans on<br>
setsebool -P -allow_ftpd_full_access on<br>
servie vsftpd restart</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
*********************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
<strong>二：yum环境光盘源搭建：</strong><br><br>
1）挂在Redhat linux 5.X光盘：<br>
mount /dev/hdc /mnt<br>
2）编辑/etc/yum.conf 增加下面的内容即可<br>
************************************</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
<br>
name=cdrom<br>
baseurl=file:///mnt/Server<br>
enabled=1<br>
gpgcheck=1</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
