[CentOS7] Memo when [Errno 14] HTTP Error 404 - Not Found appears with yum install

Hello.
always
be cute at Hello World System Solution Department.

The other day when I tried to install a package on an AWS EC2 instance (graviton), for some reason

[Errno 14] HTTP Error 404 - Not Found

An error occurred and I got stuck, so I'll leave a memo in the article.
Writing the results first, it seems that the cause is that there are few mirroring sites for AArch64 (ARM64) CPU architecture.
I hope this will be helpful for those who encounter similar errors, such as when the environment is the same.

It seems like the 5 series is a paid option

Operating environment and error details

Operating environment

cat /etc/proc/version Linux version 4.14.256-197.484.amzn2.aarch64 (xxxx@ip-xx-xx-xx-xx) (gcc version 7.3.1 20180712 (Red Hat 7.3.1-13) (GCC) )

Error when installing zabbix-agent

yum install zabbix-agent http://repo.zabbix.com/zabbix/5.0/rhel/7/aarch64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. http://repo .zabbix.com/non-supported/rhel/7/aarch64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror.

In this way, the mirror site URL also results in a 404 error, and the installation does not proceed.

What I tried

1. Delete cache

yum clean all

2. Update zabbix-agent package

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

The above two points do not solve the problem.

This is resolved

I later found out that in the case of CentOS7, there seem to be few places offering mirror sites for architectures other than x86_64. In order to make it compatible with ARM64, I installed the EPEL repository and successfully solved the problem (the version of zabbix-agent was 4, but within the expected range).
