妈的。。今天下午忙了半天也没搞定mysql的远程连接。。郁闷啊。。
最后回到家里上网无意见看到了篇比较正点的资料。。
呵呵,,
问题解决了。。
明天搞定ftp服务器。。哈哈
netstat -an | grep LISTEN 查看端口
远程连接到mysql需要做的- -
1、进入mysql,创建一个新用户xuys:
格式:grant 权限 on 数据库名.表名 用户@登录主机 identified by "用户密码";
grant select,update,insert,delete on *.* to xuys@192.168.88.234 identified by "xuys1234";
查看结果,执行:
use mysql;
select host,user,password from user;
可以看到在user表中已有刚才创建的xuys用户。host字段表示登录的主机,其值可以用IP,也可用
主机名,
将host字段的值改为%就表示在任何客户端机器上能以xuys用户登录到mysql服务器,建议在开发时
设为%。
update user set host = '%' where user = 'xuys';
2、 ./mysqladmin -uroot -ppwd reload
./mysqladmin -uroot -ppwd shutdown
3、./mysqld_safe --user=root &
记住:对授权表的任何修改都需要重新reload,即执行第3步。
如果经过以上3个步骤还是无法从客户端连接,请执行以下操作,在mysql数据库的db表中插入一条记录
:
use mysql;
insert into db
values('192.168.88.234','%','xuys','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
update db set host = '%' where user = 'xuys';
重复执行上面的第2、3步。

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
