CentOS 7搭建本地yum源和局域网yum源

看到这个都是情非得已的，话不多说，直接盘

搭建本地yum源

本地yum源，就意味着只有搭建该yum源的这台服务器能使用，其它的服务器都不能使用该yum源。搭建本地yum源的所有步骤如下：

#准备好一个centos 的镜像，我这里是CentOS-7-x86_64-DVD-1810.iso


# 在/local-yum目录创建挂载镜像的文件夹


# 将iso镜像挂载到/mnt/iso目录
mount -o loop CentOS-7-x86_64-DVD-1810.iso /local-yum

#永久挂载
vim /etc/fstab
.......
/dev/sr0 /local-yum iso9660 defaults 0 0


# 挂载成功后可以使用df -h命令查看
[root@localhost application]# df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   50G  1.9G   49G   4% /

tmpfs                     63G     0   63G   0% /sys/fs/cgroup
/dev/sda2               1014M  138M  877M  14% /boot
/dev/sda1                200M   12M  189M   6% /boot/efi
/dev/mapper/centos-home  392G  9.0G  383G   3% /home
tmpfs                     13G     0   13G   0% /run/user/0
/dev/loop0               4.5G  4.5G     0 100% /local-yum




# 修改yum配置文件，把原先的配置先备份了
cd /etc/yum.repos.d
mkdir bak
mv *.repo ./bak

#新建local.repo
vim /etc/yum.repos.d/local.repo

[base]
name=CentOS
baseurl=file:///local-yum
enabled=1
gpgcheck=0



#清除下yum 原有的信息，载入新的缓存
yum clean all
yum makecache

这样，一个崭新的本地yum源就可以使用了。

搭建局域网yum源

除了可以搭建本地yum源外，我们还可以基于HTTP方式配置yum源，这样我们就可以配置一个局域网内都可以使用的yum源。

一般都是通过apache 来搭建HTTP的yum源，本次我们使用Nginx搭建

#登陆浏览器访问查看yum仓库

#
最后，我们开始配置yum的配置文件，在
/etc/yum.repos.d
新建一个名为nginx-yum.repo 的配置文件，内容如下：

vim /etc/yum.repos.d/nginx-yum.repo[Nginx-yum]name=nginx-yumbaseurl=http://10.114.0.15:8899enabled=1gpgcheck=0

#清除下yum 原有的信息，载入新的缓存

yum clean allyum makecache

这样，局域网yum源就可以使用了
