- 先到mysql官网上下载dmg格式安装包,进行安装。
- 安装完后,命别名:
vim ~/.bash_profile
alias mysql=/usr/local/mysql/bin/mysql
alias mysqladmin=/usr/local/mysql/bin/mysqladmin
- 修改MySQL密码(版本5.7.x)
通过 –skip-grant-tables的方式启动mysqld_safe ,这个模式可以绕过mysql授权。
sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
之后进入mysql:
sudo /usr/local/mysql/bin/mysql -u root
在mysql.user中以前版本会有一个字段password,但是现在替换成了authentication_string
进入mysql之后:
mysql> update mysql.user set authentication_string=PASSWORD('123') where user=’root’;
Query OK, 1 row affected, 1 warning (0.04 sec)
Rows matched: 1 Changed: 1 Warnings: 1
mysql> flush privileges;
Query OK, 0 rows affected (0.02 sec)
mysql> quit
这时候Myqsl密码已经修改完了,我们把上面的mysqld进程干掉,通过正常途径起Mysqld服务
mysql -u root -p
mysql>
mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql>
mysql> set password for root@localhost=password(‘123');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> show databases;
