安装mariadbmysql)并创建账户

(red hat内置的安装已经是mariadb,而非mysql,因为二者差不多,所以不建议重新下载mysql,建议直接用mariadb)

安装:

[root@localhost ~]# dnf -y install mariadb*

启动:

[root@localhost ~]# systemctl start mariadb

[root@localhost ~]# systemctl status mariadb

[root@localhost ~]# firewall-cmd --permanent --add-service=mysql

[root@localhost ~]# firewall-cmd --reload

[root@localhost ~]# firewall-cmd --permanent --add-service=mariadb

Error: INVALID_SERVICE: mariadb

[root@localhost ~]# mysql_secure_installation

进入root下的mariadb(即mysql)

[root@localhost ~]# mysql -u root -p

Enter password: (这里要输入密码)
