centos7使用镜像作为本地yum源

搭建本地yum源

1. 配置网络

##配置网络命令，可使用Tab键辅助
nmcli connection modify "ens33" ipv4.method manual ipv4.addresses "192.168.131.161/24" ipv4.gateway "192.168.131.2" ipv4.dns "114.114.114.114" connection.autoconnect yes

##关闭网络并重新启动生效
nmcli con down  ens33
nmcli con up  ens33

##验证网络是否ping通
[root@localhost ~]# ping www.baidu.com

64 bytes from 36.152.44.95 (36.152.44.95): icmp_seq=1 ttl=128 time=35.8 ms

^C

2 packets transmitted, 2 received, 0% packet loss, time 1004ms
rtt min/avg/max/mdev = 35.627/35.727/35.827/0.100 ms

2. 关闭防火墙及开机自启

systemctl stop firewalld.service
systemctl disable firewalld.service

3. 关闭SELinux

##临时关闭
setenforce 0

##开机关闭，需要重启才能生效
sed -i '/SELINUX/{s/permissive/disabled/}' /etc/selinux/config 
或	vim /etc/selinux/config		
		SELINUX=disabled

4. 挂载镜像

mount /dev/sr0 /mnt/	#临时挂载

vim /etc/fstab 	##开机自启挂载；进入配置文件，并在最后一行添加下面的命令
/dev/cdrom /mnt iso9660 defaults 0 0

5. 配置本地yum

mkdir /tmp/repo							#创建存放原先的repo文件目录
mv /etc/yum.repos.d/CentOS-* /tmp/repo/	#把原先的repo文件全部移到/tmp/repo/下
vim /etc/yum.repos.d/centos7.repo		#创建本地repo文件
	[centos]
	name=centos
	baseurl=file:///mnt
	enabled=1
	gpgcheck=0

7. 检验本地yum源是否成功

[root@localhost ~]# yum clean all;yum repolist
