遇到一堆问题：直接从mysql官下载，都不行。下列是失败的：
mysql80-community-release-el8-1.noarch.rpm
mysql-8.0.34-1.el8.x86_64.rpm-bundle.tar
mysql-8.1.0-1.el9.x86_64.rpm-bundle.tar
后来想从openeuler下载应该靠谱：https://repo.huaweicloud.com/openeuler/openEuler-23.03/everything/x86_64/Packages/
就安装了这里面所有的mysql:

systemctl start mysqld
Active: active (running)
我去，不容易，不友好。
