本地sqlyog连接阿里云MariaDB数据库

本地数据库可视化客户端工具：sqlyog，当然其他工具也应该是一个道理

远程服务器：阿里云服务器上的MariaDB服务（其他远程数据库也是同样的道理）一、阿里云服务器自带MariaDB数据库，你在远程连接时，需要将3306端口添加至安全组

二、使用远程工具，连接到阿里云服务器，例如，FinalShell；

1、关于MariaDB数据库的操作

• 启动MariaDB命令：systemctl start mariadb.service
• 停止MariaDB命令：systemctl stop mariadb.service
• 重启MariaDB命令：systemctl restart mariadb.service

2、启动数据库之后

• mysql -u root -p  
• 然后输入密码
• show databases;
• use mysql;
•  UPDATE user set password=PASSWORD('*****')where user='root';  (**代表你的密码，root是你的用户名)
• GRANT ALL PRIVILEGES ON *.* TO root@'%'  WITH GRANT OPTION;
• commit;
• flush privileges;
• exit;
• 重启Maria：systemctl restart mariadb.service

3、客户端连接

 

三、其实前面的操作已经完了，但是好多和我一样的菜鸟，命令都不知道怎么敲。下面复制一下我的命令

[root@wyx ~]# mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> use mysql;

You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [mysql]> UPDATE user set password=PASSWORD('wyx123456')where user='root';
Query OK, 4 rows affected (0.01 sec)
Rows matched: 4  Changed: 4  Warnings: 0

MariaDB [mysql]> exit
Bye

=================下面第二次，上面没有重启，已经改了，但并没有生效，下面接着操作后面的==========
[root@wyx ~]# mysql -u root -p
