MAC 環境下初始化mysql root 密碼，mysqlroot

1.關掉mysql服務，打開系統設置最後的mysql,然後將mysql先關掉

2.生成一個文件命名mysql-init，文件中放入：一句話，這句話不同版本不一樣，如下：（括號裡面不包含）

alter user ‘root’@‘localhost’ identified by ‘新密碼’；(MySQL 5.7.6 and later)

set password for ‘root’@‘localhost’=password(‘新密碼’);(MySQL 5.7.5 and earlier)

3.cd /usr/local/mysql/bin/

sudo su

mysql_safe —init-file=/home/me/mysql-init &

mysql_safe —skip-grant-tables &

./mysql

flush privileges;

update mysql.user  set authentication_string = password(‘你在文件中定義的新密碼’)，password_expired = ’N’ where user = ‘root’ and host = ‘localhost’;

flush privileges;

quit;

./mysql -u root -p

輸入你的新密碼就好了
