linux mysql 数据库权限

hi 楼主，在数据库中创建包含很多，视图，索引，临时表的创建权限都能分开赋予，你可以执行 show privileges 来查看权限参数，我这边就以创建表为例，只包含查询表功能，其他修改，删除，备份没有权限；以下是步骤：

1，create user 'tom'@'%' identified by '123456'---创建用户，无权限；

2， grant create,select on wangxh2.* to tom-----把wangxh2库的所有表的创建和查询赋予tom

3，flush privileges-----刷新权限表才能起效

接下来是测试：

mysql>show databases

+--------------------+

| Database |

+--------------------+

| information_schema |

| test |

| wangxh2|

+--------------------+

3 rows in set (0.06 sec)

mysql>use wangxh2

Database changed

mysql>show tables

+-------------------+

| Tables_in_wangxh2 |

+-------------------+

| test |

+-------------------+

1 row in set (0.00 sec)

mysql>drop test

ERROR 1064 (42000): You have an error in your SQL syntaxcheck the manual that corresponds to your MySQL server version for the right syntax to use near 'test' at line 1

mysql>drop table test

ERROR 1142 (42000): DROP command denied to user 'tom'@'localhost' for table 'test'

mysql>select count(*) from test

+----------+

| count(*) |

+----------+

| 33554432 |

+----------+

1 row in set (0.01 sec)

mysql>insert into test values(1)

ERROR 1142 (42000): INSERT command denied to user 'tom'@'localhost' for table 'test'

mysql>delete from test

ERROR 1142 (42000): DELETE command denied to user 'tom'@'localhost' for table 'test'

mysql>update test set id=1

ERROR 1142 (42000): UPDATE command denied to user 'tom'@'localhost' for table 'test'

mysql>create table test1 (id int)

Query OK, 0 rows affected (0.02 sec)

mysql>insert into test1 values(1)

ERROR 1142 (42000): INSERT command denied to user 'tom'@'localhost' for table 'test1'

[mysql@localhost ~]$ mysqldump -u tom -paidengshan wangxh2 >/home/mysql/aa.sql

mysqldump: Got error: 1044: Access denied for user 'tom'@'%' to database 'wangxh2' when using LOCK TABLES

[mysql@localhost ~]$

-----------------------------------------------------------------------------------------

以上测试发现，tom对wangxh2有建表，查询表的权限，但是修改，删除，新增，备份都没有权限，达到你的需求了

1、root用户登录到mysql数据库 代码示例: /usr/local/mysql/bin/mysql -u root -p (输入密码进入mysql) 2、进入mysql，输入： 代码示例: use mysql3、查看user表的情况 代码示例: SELECT Host,User FROM user//指明主机名称，

可以使用telnet ip地址 端口进行测试远程主机数据库端口是否可以访问

要想远程数据库必须要在数据库里授权远程登录的权限

远程连接常用数据库mysql的命令是mysql -u 用户名 -h 远程IP地址 -p
