MySQL for Mac基本操作

shell> sudo /Library/StartupItems/MySQLCOM/MySQLCOM start 

(Enter your password, if necessary) 

(Press Control-D or enter "exit" to exit the shell) 

如果不使用Startup Item，输入下面的命令序列： 

shell> cd /usr/local/mysql 

shell> sudo ./bin/mysql

(Enter your password, if necessary) 

(Press Control-Z) 

shell> bg 

(Press Control-D or enter "exit" to exit the shell) 


二.创建用户 分配权限 
grant all privileges on *.* to 'user'@'localhost' with grant option 
grant all privileges on *.* to 'user'@'localhost' identified by ‘123456′; 
flush privileges; 

1.新建用户。 

登录MYSQL 
@>mysql -u root -p 
@>密码 
创建用户 
mysql> insert into mysql.user(Host,User,Password) values("localhost","phplamp",password("1234")); 
刷新系统权限表 
mysql>flush privileges; 
这样就创建了一个名为：phplamp  密码为：1234  的用户。 

然后登录一下。 

mysql>exit; 
@>mysql -u phplamp -p 
@>输入密码 
mysql>登录成功 

2.为用户授权。 

登录MYSQL（有ROOT权限）。我里我以ROOT身份登录. 
@>mysql -u root -p 
@>密码 
首先为用户创建一个数据库(phplampDB) 
mysql>create database phplampDB; 
授权phplamp用户拥有phplamp数据库的所有权限。 
>grant all privileges on phplampDB.* to phplamp@localhost identified by '1234'; 
刷新系统权限表 
mysql>flush privileges; 
mysql>其它操作 


如果想指定部分权限给一用户，可以这样来写: 
mysql>grant select,update on phplampDB.* to phplamp@localhost identified by '1234'; 
//刷新系统权限表。 
mysql>flush privileges; 


3.删除用户。 
@>mysql -u root -p 
@>密码 
mysql>DELETE FROM user WHERE User="phplamp" and Host="localhost"; 
mysql>flush privileges; 
//删除用户的数据库 
mysql>drop database phplampDB; 

4.修改指定用户密码。 
@>mysql -u root -p 
@>密码 
mysql>update mysql.user set password=password('新密码') where User="phplamp" and Host="localhost"; 
mysql>flush privileges;
