本文详细介绍了在CentOS 7上搭建HTTP Yum源的步骤。首先，需进行环境准备，包括永久关闭防火墙和SELinux，挂载系统镜像并复制到`/opt/centos`，然后配置本地Yum源。接着，安装并启动httpd服务，创建软链接将`/opt`目录内容指向`/var/www/html`，并清除httpd默认欢迎页。最后重启httpd服务，即可通过HTTP访问Yum源。

CentOS7 搭建http的yum源

1. 环境准备

• 永久关闭防火墙

[root@yum ~]# systemctl stop firewalld && systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

• 永久关闭selinux

[root@yum ~]# setenforce 0
[root@yum ~]# sed -i 's/enforcing/disabled/g' /etc/selinux/config 
[root@yum ~]# cat /etc/selinux/config | grep =
# SELINUX= can take one of these three values:
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
SELINUXTYPE=targeted 

• 挂载系统镜像源

[root@yum ~]# mount -o loop /dev/cdrom /mnt/
[root@yum ~]# mkdir /opt/centos
[root@yum ~]# cp -rf /mnt/* /opt/centos/
[root@yum ~]# umount /mnt/

• 备份原有yum源

[root@yum ~]# mkdir yumbackup
[root@yum ~]# mv /etc/yum.repos.d/* yumbackup/

• 配置centos系统镜像源

[root@yum ~]# cat << EOF > /etc/yum.repos.d/yum.repo
> [centos]
> name=centos
> baseurl=file:///opt/centos
> gpgcheck=0
> enable=1
> EOF

[root@yum ~]# cat /etc/yum.repos.d/yum.repo 
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enable=1

[root@yum ~]# yum clean all

[root@yum ~]# yum repolist

• 安装工具

yum install -y vim net-tools

2.配置http源

• 安装http

yum install -y httpd
systemctl restart httpd
systemctl enable httpd

• 创建软连接指向源路径

[root@yum html]# ln -s /opt/* /var/www/html/

• 删除httpd默认页内容

echo "" > /etc/httpd/conf.d/welcome.conf

• 重启httpd服务

systemctl restart httpd
