[root@VM-12-6-centos ~]# yum install -y httpd
已加载插件：fastestmirror, langpacks
Repository epel is listed more than once in the configuration
Loading mirror speeds from cached hostfile
没有可用软件包 httpd。
错误：无须任何处理

yum install -y epel-release
安装epel后再试试

你的yum 源有问题，先设置好yum源
你不会设置，就备份现有的源文件，然后，重新弄一个国内源，
例如配置阿里源方法：
基础源：https://developer.aliyun.com/mirror/centos
EPEL：https://developer.aliyun.com/mirror/epel

更新一下源试试，我没centos，参考Ubuntu的看看：
sudo vi /etc/apt/mirror.list
