aliyun服务器ubuntu系统+MySQL+SqlDeveloper

首先按照

https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-16-04

https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-16-04

安装MySQL

学到了如何添加用户和赋给sudo权限

https://www.digitalocean.com/community/tutorials/how-to-add-and-delete-users-on-ubuntu-16-04

adduser sammy

usermod -aG sudo sammy

不过还有两件事要做

第一件事是创建一个能够接受任何IP地址请求的Mysql用户：

切换到root用户

mysql -u root -p  

https://stackoverflow.com/questions/1559955/host-xxx-xx-xxx-xxx-is-not-allowed-to-connect-to-this-mysql-server

mysql> CREATE USER 'monty'@'localhost' IDENTIFIED BY 'some_pass';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'localhost' WITH GRANT OPTION;

mysql> CREATE USER 'monty'@'%' IDENTIFIED BY 'some_pass';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'%' WITH GRANT OPTION;

第二件事是开放阿里云端口

讲到阿里云端口需要编写安全组规则

有用的命令

netstat -ntpl

之后就是用sqlDeveloper连接MySQL

https://stackoverflow.com/questions/89696/how-do-you-connect-to-a-mysql-database-using-oracle-sql-developer

先去下载connector

https://www.mysql.com/products/connector/

然后

配置用户名密码

都是MySQL用户名密码
