While learning the above lesson with dot installation
$ sudo yum -y install httpd
After entering the command [vagrant @ localhost ~]
Error: File contains no section headers.
file: file://///etc/yum.repos.d/CentOS-Base.repo, line: 1
I got an error like this.

When I referred to the above article, I found that the error was "The first line of etc/yum.repos.d/CentOS-Base.repo is strange".
$ sudo vi /etc/yum.repos.d/CentOS-Base.repo
When I executed and looked at the data inside, the first line was something like entOS-Base.repo.
It should be # CentOS-Base.repo (don't forget the space after #!), Change it and try again.
$ sudo yum -y install httpd
After executing, I was able to successfully complete!
There are many things I can't do at all when resolving errors, but most of them are typos, so be sure to check carefully.
