Solution to the forgotten mysql password in MACMy recent project used MySQL. I had installed one before, but I forgot the password I set at that time, and then I embarked on the bumpy road of changing the password. After searching a lot of information on Baidu and Google, I still found that there are pitfalls for programmers everywhere. So I decided to write a blog covering solutions to forgotten passwords in various situations.
Situation 1: Download the dmg file directly from the mysql official website for installation, forget the password
1.Close the mysql server
sudo /usr/local/mysql/support-files/mysql.server stop
2.Enter the directory
cd /usr/local/mysql/bin
3. Obtain permission
sudo su
4.Restart the server
./mysqld_safe --skip-grant-tables &
5.control + D to exit editing
6.Configure short command
alias mysql=/usr/local/mysql/bin/mysql
7.Enter mysql
Command modemysql
use mysql
flush privileges;
10.Reset Password
set password for 'root'@'localhost'=password('新密码');

Case 3: In this case This is a rather tricky situation. After downloading mysql, I forgot about it for a long time, and then downloaded another one. I found that the database I downloaded first directly prompted me to enter the password. Then enter the command according to situation 1 or 2 and it cannot be modified successfully. Afterwards, modifying my.cnf (now changed to my-default.cnf) according to the method introduced online did not work. If you unfortunately encounter this situation, please follow the steps below

sudo rm /usr/local/mysql sudo rm -rf /usr/local/var/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* vim /etc/hostconfig and removed the line MYSQLCOM=-YES-rm -rf ~/Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /var/db/receipts/com.mysql.*
