php - linux starts two mysql services at one time

Question

Virtual machine environment: Port 192.168.0.140

        本地可以连接使用这个端口
        有密码
        使用navicat 工具可以进入mysql 服务

The virtual machine uses mysql -uroot -p
Entered the mysql service and found that the database connected above was not the same database! ,
And the password is empty
There is no mysql table inside either

So I suspected that two mysql services were installed
Then I found the data directory in phpstudy

Inside is the data I used to connect to the database using 192.168.0.140

What should I change so that mysql -uroot -p
also points to this directory, or do I need to move the data directory?
