一，要求

1，安装httpd软件

2，定义防火墙规则

3，设置selinux为强制模式

4，web服务器的端口为8080

5，web服务器的内容目录为 /www/8080

6，所有操作开机有效

7，所有操作必须进行判断

8，在合适的实际输出合适的信息，如果有日志就更好了

二，具体实施

touch /etc/yum.repos.d/rpm.repo
echo -e "[baseos]\nname=baseos\nbaseurl=/mnt/BaseOS\ngpgcheck=0\n[appstream]\nname=appstrean\nbaseurl=/mnt/AppStream\ngpgcheck=0" > /etc/yum.repos.d/rpm.repo
