有没有人知道mysql这数据库最大可以建多少张表格?
我公司现在要建支持二级域名日语的博客
我上网查了一下,只找到wordpress mu这套系统能符合要求,而且我还是用wordpress中的日语语言包,勉强可以用
但是,现在有个问题就是公司要建几十万的博客,而这套系统的数据库设计是每创建一个博客就会新创建8张表
也就是说,我想建几十万博客的话,那就要创建出几百万张表,
我觉得这个实在有点行不通,所以想问一下这里的牛人,mysql这样的数据库有没有最大上限的表格数啊?
大概是多少?
------解决方案--------------------
那么大肯定不行
你可以建立多个数据库吗
------解决方案--------------------
我想这应该受到文件系统最大文件数限制。一个MyISAM表是3个文件,所以你这个"几百万"还得乘个3。
------解决方案--------------------
数据库应该不会坏掉,应该是创建失败。以前我google过linux下可以创建的最大文件数,根目录下可创建的有限(人云亦云的说),子目录下是受到inode的数量限制(这点应该是确定的,但我也没进一步查),现在我一个目录下的文件数到10万了,网站速度没看出影响,但ll一下目录的时间可以喝点茶了。其实想像一下,目录本身也是一个数据库。
------解决方案--------------------
搞这么大的项目,用别人的服务器,总归不太好。
------解决方案--------------------
用空间商的空间?然后建一个如此庞大的项目。这个有点。。。。你们老板是不是也忒欠考虑了?带宽问题呢?数据备份呢?这些都不考虑了?
------解决方案--------------------
没有限制,主要由你的操作系统和硬件来限制。
------解决方案--------------------

最好是和别人合租一台 或者合买一台

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

How to solve the MySQL "Access denied for user" error: 1. Check the user's permission to connect to the database; 2. Reset the password; 3. Allow remote connections; 4. Refresh permissions; 5. Check the database server configuration (bind-address, skip-grant-tables); 6. Check the firewall rules; 7. Restart the MySQL service. Tip: Make changes after backing up the database.

phpMyAdmin is not just a database management tool, it can give you a deep understanding of MySQL and improve programming skills. Core functions include CRUD and SQL query execution, and it is crucial to understand the principles of SQL statements. Advanced tips include exporting/importing data and permission management, requiring a deep security understanding. Potential issues include SQL injection, and the solution is parameterized queries and backups. Performance optimization involves SQL statement optimization and index usage. Best practices emphasize code specifications, security practices, and regular backups.
