解决mac使用homebrew安装MySQL无法登陆问题

如果你电脑是mac的，使用homebrew安装mysql是一个非常便捷的方式，但是还是会出现一些问题；

首先保证你已经安装了mysql,如果是通过homebrew安装的，输入mysql.server start 启动服务

如果在输入

mysql -u root

出现这个错误error 1045 (28000): access denied for user (using password: yes)，应该是修改初始密码没有成功

解决步骤

（1）终端输入mysqld_safe --skip-grant-tables 显示如下

2017-03-21t11:44:11.6nz mysqld_safe logging to '/usr/local/var/mysql/zhongchengmingdemacbook-air.local.err'.
2017-03-21t11:44:11.6nz mysqld_safe logging to '/usr/local/var/mysql/zhongchengmingdemacbook-air.local.err'.
2017-03-21t11:44:11.6nz mysqld_safe a mysqld process already exists

 （2）再次输入mysql -u root显示如下
