MySQL8.0.32在Linux下的安装

Install the MySQL8.0 version of Linux

1、Prepare a Linux server

Cloud server or virtual machine can be used;

Linux should be CentOS7;

2、Download the MySQL installation package for Linux

地址：https://dev.mysql.com/downloads/mysql/

3、Upload the MySQL installation package

Here I upload through Xtp,you can also choose your own uploading method.

4、Create a directory and decompress it

5、Install the MySQL installation package

Here we need to follow exactly the steps to perform rpm operations.

6、Start the MySQL service

• systemctl start mysqld

• systemctl restart mysqld
• systemctl stop mysqld

7、Example Query the automatically generated password of user root

Copy a new session and enter:

• vi /var/log/mysqld.log

And then we copy the password, enter to “Enter Password”.

Successful connection!

8、Change the user password

After logging in to MySQL, you need to change the automatically generated inconvenient password into a familiar password that is easy to remenber.

alter user 'root'@'localhost' identified by 'root';

An error occurs when executing the above SQL because the password is too simple, We can set the password complexity to simple and the password length to 4.

set global validate_password.policy = 0;
set global validate_password.length = 4;

After relaxing the password verification policy, execute the aforementioned command to reset the password.

9、Create user

The default ‘root’ user can only access the current node ‘localhost’ and can’t be accessed remotely.We also need to create a root account for remote access.

create user 'root'@'%' identified with mysql_native_password by '1234';

10、Assign permissions to the ‘root’ user.

grant all on *.* to 'root'@'%';
