今在服务器上 有mysql 数据库,远程访问,不想公布root账户,所以,创建了demo账户,允许demo账户在任何地方都能访问mysql数据库中shandong库。
方案一:
在安装mysql的机器上运行:
1: 创建user用户
CREATE USER demo IDENTIFIED BY “123456”
2、
mysql>GRANT ALL PRIVILEGES ON shandong.* TO 'demo'@'%'WITH GRANT OPTION
//赋予任何主机访问数据的权限,也可以如下操作
GRANT ALL PRIVILEGES ON shandong.* TO 'demo'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
3、
mysql>FLUSH PRIVILEGES
//修改生效
4、
mysql>EXIT
//退出MySQL服务器,这样就可以在其它任何的主机上以demo身份登录

另外,当用客户端连接 mysql 时,发现无法连接,看来需要对用户进行重新授权。操作如下:
[root@cicro108 mysql]# bin/mysql -uroot -p -h 127.0.0.1 -A cws3
Enter password:
Welcome to the MySQL monitor. Commands end with or /g.
Your MySQL connection id is 1863 to server version: 4.1.20-standard
Type 'help;' or '/h' for help. Type '/c' to clear the buffer.
mysql> grant ALL PRIVILEGES ON *.* to root@"%" identified by "mysql" ;
Query OK, 0 rows affected (0.17 sec)
发现这样更改权限以后,远程仍然不能连接,但是用下面的操作就可以了。
mysql> grant ALL PRIVILEGES ON *.* to root@"%" identified by "mysql" WITH GRANT OPTION;
Query OK, 0 rows affected (0.17 sec)
此刻, root 可以被远程连接,当然这里建立其他非 root 用户也可以远程连接。
方案二:
MySQL 1130错误解决方法:
通过MySQL-Front或MySQL administrator连接MySQL的时候发生的这个错误
ERROR 1130: Host ***.***.***.*** is not allowed to connect to this MySQL server
说明所连接的用户帐号没有远程连接的权限,只能在本机(localhost)登录。
需更改 MySQL 数据库里的 user表里的 host项
把localhost改称%
具体步骤:登陆到MySQL
首先 use MySQL;
按照别人提供的方式update的时候,出现错误。
MySQL> update user set host='%' where user = 'root';
ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'
然后查看了下数据库的host信息如下:
MySQL> select host from user where user = 'root';
+-----------------------+
| host |
+-----------------------+
| % |
| 127.0.0.1 |
| localhost.localdomain |
+-----------------------+
3 rows in set (0.00 sec)
host已经有了%这个值,所以直接运行命令:
MySQL>flush privileges;
再用MySQL administrator连接...成功!!bitsCN.com

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
