sudo systemctl set-environment MYSQLD_OPTS="--skip-grant-tables --skip-networking"

# 启动MySQL
sudo systemctl start mysqld

# 以root账号登录MySQL，并重设密码
mysql -uroot

update mysql.user set authentication_string=PASSWORD("NewPassword") where User='root' AND Host = 'localhost';
flush privileges;
quit

# 停止MySQL
