mysql官方没有提供arm64架构的安装源 需要安装mysql的请查看这篇博客

        【树莓派安装mysql5.7】 https://linuxer.top/archives/raspi-install-mysql57.html

    我本地安装了 mariadb 为了省事，

下面是按照步骤

  1，更新软件包

 

sudo apt update

2，安装Mariadb服务端

sudo apt install mariadb-server

3,安装完成后查看安装情况

sudo systemctl status mariadb
或者
service mariadb status

输出一下内容

mariadb.service - MariaDB 10.3.27 database server
   Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2021-03-01 14:36:28 PDT; 19min ago
     Docs: man:mysqld(8)
           https://mariadb.com/kb/en/library/systemd/
 Main PID: 4509 (mysqld)
   Status: "Taking your SQL requests now..."
    Tasks: 30 (limit: 2359)
   Memory: 78.6M
   CGroup: /system.slice/mariadb.service
           └─4509 /usr/sbin/mysqld  

4,基本配置

sudo mysql_secure_installation

脚本执行过程中，系统将提示您为 root 帐户设置密码，删除匿名用户，限制 root 用户对本地计算机的访问权限并删除测试数据库

类似如下:

 

...
Enter current password for root (enter for none):
...
Set root password? [Y/n] Y
New password: 
Re-enter new password: 
...
Remove anonymous users? [Y/n] Y
...
Disallow root login remotely? [Y/n] Y
...
Remove test database and access to it? [Y/n] Y
...
Reload privilege tables now? [Y/n] Y
...
Thanks for using MariaDB!

连接测试

mysql -u root -p

 

5,配置root远程访问

nano /etc/mysql/mariadb.conf.d/50-server.cnf 

修改如下:

bind-address            = 0.0.0.0
#bind-address改为0.0.0.0，从而可以外网访问

6，配置权限

-> # mysql -h localhost -P 3306 -u root -p
Enter password:
