MySQL5.7 忘记root密码,怎么破?
关服
# kill -0 $mysql_pid
# kill $mysql_pid
免密启动
# /usr/local/mysql57/bin/mysqld_safe --defaults-file=/etc/my.cnf --skip-grant-tables &

改密码呀
# /usr/local/mysql57/bin/mysql -S /tmp/mysql.sock
mysql> update mysql.user set authentication_string=password(‘4a68a3c809c38e31‘) where user=‘root‘ ;
Query OK, 1 row affected, 1 warning (0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 1
mysql> quit
Bye
重启
# /usr/local/mysql57/bin/mysqladmin -S /tmp/mysql3308.sock shutdown
2017-12-08T10:33:02.360399Z mysqld_safe mysqld from pid file /data/database/mysql/host-30-0-0-196.pid ended
[1]+ Done 阿/usr/local/mysql57/bin/mysqld_safe --defaults-file=/etc/my.cnf --skip-grant-tables
# /usr/local/mysql57/bin/mysqld_safe --defaults-file=/etc/my.cnf
还得再改一次
You must reset your password using ALTER USER statement before executing this statement.
mysql> alter user [email protected] identified by ‘4a68a3c809c38e31‘;
Query OK, 0 rows affected (0.01 sec)
可以了
