Mysql 5.7.20 installation tutorial on Mac OS:

MySQL 5.7 is installed in TAR. GZ mode on Mac OS X. Compared with MySQL 5.6, MySQL 5.7 is installed in two different ways:

1: The initialization method is changed from scripts/mysql_install_db -- user = mysql to bin/mysqld -- initialize -- user = mysql;

2: The initial password generation is changed. After tar gz Mode Initialization is complete in version 5.6, the root password is blank by default. A temporary root password is generated in version 5.7 after Initialization is complete;

1. Enter the following address in the browser:

Https://dev.mysql.com/downloads/mysql/

Http://www.bkjia.com/softs/451120.html

　

2. Go to the following page: click the following position and select skip logon.

Click this button to download it directly.

　

3. After the download is complete, double-click it to open it. The following page is displayed, and click Continue.

　　

Continue as you are about to install other software.

4. Start MySQL

After the installation is complete, go to the settings to view the following options. If MySQL exists, it indicates that the installation is successful.

　　

Click to start MySQL

　　

5. Change the Database Password

After the terminal is started, open the terminal

　　aliasmysql=/usr/local/mysql/bin/mysql

　　aliasmysqladmin=/usr/local/mysql/bin/mysqladmin　　

Copy the preceding two commands to the terminal and give the two addresses a temporary alias.

The purpose is to directly execute mysql or mysqladmin in the next execution.

No need to switch back and forth Directories

　
　

Next, modify the Database Password and run the following command:

　　mysqladmin -u root -p password root123

Root123 is my new password. You can change it to the password you want to set.

Press enter and prompt to enter the password. In this case, the entered password is not your computer password.

It is the password of the database.

The default user name and password are available before 5.7, both of which are root

However, after 5.7, only the Default User Name P: root

The default password will be automatically assigned to you, and will be automatically assigned to you during installation.

You can also view it in the mac notification bar.

A Database Password is automatically generated.

　　

The default password is localhost: all the content following it. Enter it and press Enter.

(Mac cannot input the password in the command line, so do not enter an error when entering the password)

　　

6. Enter the database

The above information is displayed, and the modification is successful.

Next, go to the database.

Make sure that:aliasmysql=/usr/local/mysql/bin/mysql

If the command is not executed, you must switch to the preceding directory to execute the mysql command.

Otherwise, the system prompts that mysql is not found.

Run the following command:mysql -u root -p

Note:-p is followed by nothing, and press Enter.

You will be asked to enter the password. At this time, the password is the one you modified on it.

What I entered here is: root123

The following information is displayed, indicating that the database has entered.
