密码错误的终端信息如下所示:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)或者: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) 忘记密码的解决方式就是重新设置密码,首先通过终端停止 MySQL 服务: FSdeMacBook-Pro:mysql fs$ support-files/mysql.server status SUCCESS! MySQL running (9872) FSdeMacBook-Pro:mysql fs$ support-files/mysql.server stop Shutting down MySQL . SUCCESS! 通过安全模式运行 MySql 并且跳过授权: FSdeMacBook-Pro:bin fs$ ./mysqld_safe --skip-grant-tables & [1] 9933 FSdeMacBook-Pro:bin fs$ 2017-09-01T02:48:32.6NZ mysqld_safe Logging to '/usr/local/mysql/data/FSdeMacBook-Pro.local.err'. 2017-09-01T02:48:32.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data 这时候我们会发现 MySQL 已经重新启动了: FSdeMacBook-Pro:~ fs$ ps -ef|grep mysql 501 10023 10017 0 10:50上午 ttys000 0:00.00 grep mysql 501 9933 9878 0 10:48上午 ttys002 0:00.02 /bin/sh ./mysqld_safe --skip-grant-tables 501 10013 9933 0 10:48上午 ttys002 0:00.32 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --skip-grant-tables --log-error=/usr/local/mysql/data/FSdeMacBook-Pro.local.err --pid-file=/usr/local/mysql/data/FSdeMacBook-Pro.local.pid在新的终端里进行登录(无需密码): FSdeMacBook-Pro:bin fs$ ./mysql -u root Welcome to the MySQL monitor.

至此,密码重置完成
