1.查看数据库:
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
5 rows in set (0.25 sec)
2.创建数据库,create 数据库名字 default charset 编码格式 collate 字符集;
mysql> create database test_db default charset utf8 collate utf8_general_ci;
Query OK, 1 row affected, 2 warnings (0.21 sec)
3:使用数据库
mysql> use test_db;
Database changed
4.用户管理:
4.1:创建用户:
mysql> create user 'test'@'localhost' identified by '';
Query OK, 0 rows affected (0.03 sec)
出现错误: The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
解决:
mysql> flush privileges;
Query OK, 0 rows affected (0.05 sec)
4.2删除用户:
mysql> drop user 'test'@'localhost';
Query OK, 0 rows affected (0.11 sec)
4.3修改用户名;
mysql> rename user 'test'@'localhost' to 'new_test'@'localhost';
Query OK, 0 rows affected (0.04 sec)
4.4修改密码
set password for 'name' =password('new_password'); 我mac上的mysql 这个会语法错误，版本是Server version: 8.0.13 MySQL Community Server - GPL,查询后判断为新版本的不支持set password的语法
mysql> alter user 'new_test'@'localhost' identified by '';
Query OK, 0 rows affected (0.08 sec)
5.权限相关:
5.1显示用户的权限:
mysql> show grants for 'root'@'localhost';
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for root@localhost |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `root`@`localhost` WITH GRANT OPTION |
| GRANT BACKUP_ADMIN,BINLOG_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GROUP_REPLICATION_ADMIN,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_SLAVE_ADMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SET_USER_ID,SYSTEM_VARIABLES_ADMIN,XA_RECOVER_ADMIN ON *.* TO `root`@`localhost` WITH GRANT OPTION |
| GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
3 rows in set (0.01 sec)
5.2授权,必须写明表名,如果是所有加上*;
权限需要小于自己的权限，注意host的限制，
mysql> grant select on mysql.* to 'new_test'@'localhost';
Query OK, 0 rows affected (0.07 sec)
all privileges 除grant外的所有权限
select 仅查权限
select,insert 查和插入权限
