我似乎无法弄清楚如何安装 systemd。我正尝试将 AWS 上的 mysql 服务器从 5.5 升级到 5.6。尝试安装时出现以下错误 - “需要：systemd”
关于问题可能是什么或者如何安装，您有什么想法吗？我已经尝试过了sudo yum install systemd。
$ sudo yum install mysql-community-server
Loaded plugins: priorities, update-motd, upgrade-helper
4 packages excluded due to repository priority protections

Requires: systemd
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
有什么想法吗？谢谢！
