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 # 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% / devtmpfs 63G 0 63G 0% /dev tmpfs 63G 0 63G 0% /dev/shm tmpfs 63G 11M 63G 1% /run 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
