搭建本地yum源
本地yum源，就意味著只有搭建該yum源的這臺服務(wù)器能使用，其它的服務(wù)器都不能使用該yum源。搭建本地yum源的所有步驟如下：
#準備好一個centos?的鏡像，我這里是CentOS-7-x86_64-DVD-1810.iso #?在/local-yum目錄創(chuàng)建掛載鏡像的文件夾 #?將iso鏡像掛載到/mnt/iso目錄 mount?-o?loop?CentOS-7-x86_64-DVD-1810.iso?/local-yum #?掛載成功后可以使用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，把原先的配置先備份了 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，載入新的緩存 yum?clean?all yum?makecache 這樣，一個嶄新的本地yum源就可以使用了。
搭建局域網(wǎng)yum源
除了可以搭建本地yum源外，我們還可以基于HTTP方式配置yum源，這樣我們就可以配置一個局域網(wǎng)內(nèi)都可以使用的yum源。
一般都是通過apache 來搭建HTTP的yum源，本次我們使用Nginx搭建
#官網(wǎng)下載nginx1.18.0 wget?http://nginx.org/download/nginx-1.18.0.tar.gz #安裝依賴包，NGINX是C語言寫的，pcre-devel支持正則表達式，openssl?開啟加密 [root@proxy?~]#?yum?-y?install?gcc?pcre-devel?openssl-devel??? #創(chuàng)建NGINX用戶，為了安全起見，不允許登錄系統(tǒng) [root@proxy?~]#?useradd?-s?/sbin/nologin?nginx?? #解壓，安裝，這里把nginx?部署在/home/application/nginx?目錄下 [root@proxy?~]#?mkdir?/home/application/nginx?
