通过以root或具有sudo权限的用户身份使用CentOS软件包来安装MySQL 8.0
<code># sudo dnf install @mysql/<code>
@mysql模块将安装MySQL及其所有依赖项。
安装完成后，通过运行以下命令来启动MySQL服务并使它在启动时自动运行：
<code># systemctl start mysqld# systemctl enable --now mysqld/<code>
要检查MySQL服务器是否正在运行，请输入：
<code># systemctl status mysqld/<code>
显示样例：
<code>mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since Sun 2020-2-12 06:07:35 UTC; 1min 59s ago Docs: man:mysqld(8) http://dev.mysql.com/doc/refman/en/using-systemd.html Process: 4633 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) Main PID: 4708 (mysqld) Status: "Server is operational" Tasks: 38 (limit: 9584) Memory: 496.4M CGroup: /system.slice/mysqld.service └─4708 /usr/sbin/mysqldFeb 12 06:07:23 centos8 systemd[1]: Starting MySQL Server...Feb 12 06:07:35 centos8 systemd[1]: Started MySQL Server./<code>
