1、下载以.dmg结尾mysql安装包

mysql下载地址：http://dev.mysql.com/downloads/mysql/

安装过程中，会有一个弹窗提示，注意：XXX的位置是你的初始登录密码

2016-08-17T15:58:04.890314Z 1 [Note] A temporary password is generated for root@localhost: XXX

If you lose this password, please consult the section How to Reset the Root Password in the MySQL reference manual.

 

2、安装完成之后，设置系统变量，

vim /etc/profile 

export PATH=$PATH:/usr/local/mysql/bin/

 

3、打开电脑-》系统偏好设置-》Start MySQL Server

启动服务

 

4、发现登录之后，查询命令输入无用，

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

bash-3.2# mysql -u root -p

Enter password: XXX（初始登录密码）

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

bash-3.2# mysql -u root -p

Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

 

mysql> show databases;

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> select version(),current_date;

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

 

5、所以你必须重设登录密码

mysql> SET PASSWORD = PASSWORD('你自己设置的密码');
Query OK, 0 rows affected, 1 warning (0.03 sec)

mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.03 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.03 sec)
