centos7 yum安装 mariadb

从最新版本centos7开始，默认的是 Mariadb而不是mysql！

使用系统自带的repos安装很简单：

yum install mariadb mariadb-server

systemctl start mariadb ==> 启动mariadb

systemctl enable mariadb ==> 开机自启动

firewall-cmd --permanent --add-port=3306/tcp ==> 开放端口，允许远程访问

systemctl restart firewalld==> 重启防火墙

mysql_secure_installation ==> 设置 root密码等相关

mysql -uroot -p密码 ==> 测试登录！

授权root远程任何机器都能登陆

use mysql;

update mysql set host=‘%‘ where user=‘root‘ and host=‘localhost‘;

flush privileges;

或

grant all privileges on *.* to ‘[email protected]%‘ identified by ‘密码‘ with grant option;

flush privileges;
