(3)安装mysql 服务端
$sudo apt-get install mysql-server
- 设置输入mysql root用户的密码和确认密码
(4)登录mysql
使用命令$mysql -uroot -p123456
其中root是用户,123456是设置的密码,这些根据自己情况进行相应修改
经过上面操作，就完成了数据库的安装和配置。
二:让mysql连接工具Navicat Premium 可以连接到服务器的mysql
1.首先sufo ufw status查看防火墙是否开启，状态为inactive说明没有开启防火墙。
2.然后输入netstat -an|grep 3306查看端口启动和占用情况，可以看到绑定为127.0.0.1，这块需要我们修改为0.0.0.0，下面会讲到。
3.首先得修改mysql访问权限，输入mysql -u root -p，回车，然后输入密码123456进入mysql命令行。
4..输入grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
授予 所有 权限 给 库名.表名 to 用户@ip地址 通过密码"123456" 确认连接
指定所有客户端都可以使用root账户访问mysql。
5.输入flush privileges; 立刻刷新权限生效
6.输入exit;退出mysql命令行。
7.输入cd /etc/mysql/mysql.conf.d进入mysql配置目录
将127.0.0.1 改为 0.0.0.0
8.输入sudo /etc/init.d/mysql restart 重启mysql
9.使用Navicat Premium 连接Ubuntu上的mysql
