在ubuntu上安装和使用mysql

在ubuntu上使用MySQL要比windows上方便的多，只需三步就行了。

第一步:

在终端上输入:sudo apt install mysql-server回车即可安装mysql

第二步:

在终端上输入:sudo mysql -u root -p 按两次回车即可登入mysql，最开始的root用户是没有密码的。

第三步：

通过sudo mysql -u root -p命令进入mysql后，再输入:ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';把root用户的密码改成：123456

当然密码可以改成你自己的密码，做这一步是为了给Mysql加一个密码，没有密码的话就没有办法访问数据库了。

你想做的产品已经有很多人在做了，那还有做的必要吗？

 对于这个问题我想用一个案例来解答。 在1879年奔驰是第一家生产汽车的企业，从1879年到现在一百多年的时间不断有新的人入局汽车行业，并且都过的不错。 在1879年的30年后1908年亨利福特成立了，就算是现在仍然有百度小米华为等互联网大厂入局汽车行业。 为什么在汽车这样的红海市场新人仍然有机会？因为不存在任何一款产品能满足人的所有需求，五菱宏光满足了低收入群体的需求，法拉利满足的是高端人士的需求。就比如成立没多久的特斯拉做的是电动汽车，还有那些互联网大厂做的是自动驾驶。 这说明从来没有完美无缺的产品，产品总有缺点，而机会就来源于对这些缺点的改进，永远不要低估自己的想法。
