无法在安全模式下启动 mysql

Question

根据这个问题Access Denied for MYSQL ERROR 1045 I should be able to start MySQL in safe mode with

sudo mysqld_safe --skip-grant-tables

但这只是将以下几行记录到 STDOUT：

151116 17:46:46 mysqld_safe Logging to '/usr/local/var/mysql/MacBook-Pro.local.err'.
151116 17:46:46 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
151116 17:46:46 mysqld_safe mysqld from pid file /usr/local/var/mysql/MacBook-Pro.local.pid ended

并将我返回到命令行。引用的错误日志在此处具有相同的最后 2 行输出。当我尝试连接到 MySQL 时，我得到：

mysql -uroot -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

刚刚在 mac 上遇到了完全相同的问题。我能够通过以下步骤重置 root 密码。

mysqld --skip-grant-tables  # this will run mysql 
    
mysql -u root
mysql> FLUSH PRIVILEGES;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';

注意：似乎较新版本的 mysql 在运行“sudo mysqld_safe --skip-grant-tables”时出现错误。
