Preface

This procedure explains how to install MySQL and MySQL Workbench using Homebrew on macOS. This is a fork of these instructions, to make them more concise and solve the issues reported here.

MySQL

To install MySQL enter :

• brew install mysql
• brew services start mysql
• then run mysql_secure_installation and follow the instructions

MySQL Workbench

install via HomeBrew Cask: brew cask install mysqlworkbench

phpMyAdmin

• install brew install phpmyadmin
• edit /private/etc/apache2/httpd.conf file as sudo
• add below code block at the end:

Alias /phpmyadmin /usr/local/share/phpmyadmin
    <Directory /usr/local/share/phpmyadmin/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        <IfModule mod_authz_core.c>
            Require all granted
        </IfModule>
        <IfModule !mod_authz_core.c>
            Order allow,deny
            Allow from all
        </IfModule>
    </Directory>


LoadModule php7_module /usr/local/opt/php/lib/httpd/modules/libphp7.so

    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

and make sure you have the line:

DirectoryIndex index.html index.php home.pl index.cgi

• then sudo apachectl restart

Visual Studio Code connection

• Install MySQL plugin
• run mysql - u <user> -p to enter mysql
• run ALTER USER '<user>'@'<server>' IDENTIFIED WITH mysql_native_password BY '<password>';
• if your password is not accepted:

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

• run SHOW VARIABLES LIKE 'validate_password%'; to see the password policies
• run SET GLOBAL <Variable_name> = <New_Value>; to change

Python

• install pip3 install mysql-connector
• run the blow code to test your Python connection:

import mysql.connector
 
mydb = mysql.connector.connect(
    host="localhost",
    user="<user>",
    passwd="<password>",
    auth_plugin='mysql_native_password',
)
 
print(mydb)

and using Pandas to run and fetch the results of MySQL queries:

df = pd.read_sql_query("SELECT * FROM <table>", mydb)
df.head()

Jupyter

• Install pip3 install ipython-sql
• pip3 install mysqlclient
• now you should be able to run these cells and get pretty-printed HTML output:

# 
%sql mysql+mysqldb://<user>:<password>@localhost/<dataBase>
 
# sql
 
SELECT *
FROM <table>;
