当远程连接MySQL数据库的时候显示Can't connect to MySQL server (10060),我们从以下几个方面入手,找出错误的原因:
1.网络不通。
检查能不能ping通。
2.防火墙设置。
防火墙是否放过mysql的进程,是否屏蔽了mysql的3306端口。
3.mysql的账户设置。
mysql账户是否不允许远程连接。如果无法连接可以尝试以下方法:
<ol> <li><span>mysql -u root -p //登录MySQL </span></li> <li><span> </span></li> <li> <span>mysql</span><span>></span><span> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION; //任何远程主机都可以访问数据库 </span> </li> <li><span> </span></li> <li> <span>mysql</span><span>></span><span> FLUSH PRIVILEGES; //需要输入次命令使修改生效 </span> </li> <li><span> </span></li> <li> <span>mysql</span><span>></span><span> EXIT //退出 </span> </li> </ol>
也可以通过修改表来实现远程:
<ol> <li><span>mysql -u root -p </span></li> <li><span> </span></li> <li> <span>mysql</span><span>></span><span> use mysql; </span> </li> <li><span> </span></li> <li> <span>mysql</span><span>></span><span> update user set </span><span>host</span><span> = </span><span>'%'</span><span> where </span><span>user</span><span> = </span><span>'root'</span><span>; </span> </li> <li><span> </span></li> <li> <span>mysql</span><span>></span><span> select host, user from user; </span> </li> </ol>

GRANT ALL PRIVILEGES
一。 改表法。可能是你的帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,从"localhost"改称"%"
1. mysql -u root -pvmwaremysql>use mysql;
2. mysql>update user set host = '%' where user = 'root';
3. mysql>select host, user from user;
二. 授权法。
例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。
1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
2.FLUSH PRIVILEGES;
如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器,并使用mypassword作为密码
1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
2. FLUSH PRIVILEGES;
另外一种方法.
在安装mysql的机器上运行:
1、d:\mysql\bin\>mysql -h localhost -u root
//这样应该可以进入MySQL服务器
2、mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION
//赋予任何主机访问数据的权限
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root身份登录啦!
ps:安装mysql后,增加mysql的root用户的密码: mysql -u root password 'your_password‘

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query.

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

How to implement HTTP streaming in C++? Create an SSL stream socket using Boost.Asio and the asiohttps client library. Connect to the server and send an HTTP request. Receive HTTP response headers and print them. Receives the HTTP response body and prints it.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.
