坑爹的nextgen-gallery插件导致MySQL binlog暴涨

我的Blog在优化过后,一直运行良好,速度也很快。可是从昨天开始突然就变得很卡,登陆到服务器上一看,我擦,磁盘空间占用率100%。仔细一看MySQL binlog占据了绝大部分空间,增长速度迅猛,每10分钟500M的节奏。
这肯定不正常啊,我去。我平均每个月才更新1-3文章。而且前来评论的人也不多,就算是Spam也不会有这么大的量啊。为了找出到底是什么SQL的干活,我停掉了Nginx,然后登陆到mysql中,选定一个binlog文件,执行"mysql -uroot -p -e 'show binlog events in 'binlog.000041' limit 10;' > /tmp/fuckedbyng.log",然后就看到了不断重复的那个坑爹的SQL。
通过这个SQL中的相关内容,Google到了问题的原因,那就是坑爹的刚刚更新过的nextgen-gellery插件的一个Bug。

在上面的论坛中,有人给出了解决方案,就是注释掉一部分更新后产生的新的相关代码。
因为我已经被激怒了,所以我首先按照以上方法修正了这个bug,再重新启动了我的Nginx,接着直接删除了这个坑爹的插件。其实我本身也不太用得上这个相册插件,呵呵。

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. If successful, a confirmation message will be output.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

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.

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.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
