基于之前设计开发的mysql审计插件,以及《MySQL审计插件安装使用说明文档》的内容介绍,对完善后的mysql审计插件进行补充和说明。

目的

基于之前设计开发的mysql审计插件,以及《MySQL审计插件安装使用说明文档》的内容介绍,对完善后的mysql审计插件进行补充和说明。主要对新增内容进行详细说明,进一步完善审计插件的功能。

新增内容

针对之前版本中存在的不足,功能不够完善的问题,对MySQL审计插件进行进一步的开发和完善。新增内容主要有:

1、增加审计数据库、数据表功能。

之前版本中没有实现该功能,在当前版本中,将审计选项中audit_dbs、audit_tables的处理实现。可以审计某些数据库,或者某些数据表,有利于针对不同应用系统的特殊应用。从而配合审计粒度,对审计内容进行进一步的细化和定制。

2、增加忽略审计的用户、数据库、数据表功能。

鉴于审计应用的特殊性,添加忽略的审计用户、数据库、数据表功能。可以实现忽略某个或某些用户的操作记录;忽略某个或某些数据库的操作记录;忽略某个表的操作记录。这样可以使得当审计的内容较多,而审计中需要剔除某些不必要的审计内容的情况下,这些参数可以有效简化审计的选项配置。

增加的配置文件的选项:

选项

功能

ignore_users

忽略的用户

ignore_dbs

忽略的数据库

ignore_tables

忽略的数据表

选项的设置格式在配置文件中给出了具体的说明,类似audit_users、audit_dbs、audit_tables选项。

在添加忽略的审计用户、数据库、数据表与审计对象发生冲突时,将按照忽略优先的原则进行。例如:audit_dbs = important、audit_tables = test.test、ignore_dbs = test,ignore_tables = important.test,那么审计的内容会首先忽略important.test表的所有操作,而审计test.test数据表的所有操作,然后忽略test数据库的所有操作,审计important数据看的操作。

3、增加审计操作的数据库信息。

由于操作的sql语句中几乎不会直接写操作的数据库,而仅靠sql语句不能有效的辨识操作的数据库。在存在不同数据库中有相同数据表的情况下,数据库审计不能有效的跟踪审计内容。增加数据库信息,可以有效的提高sql审核的内容。

文件输出格式

文件格式分为两种,,分别为连接审计和操作审计。

1、连接审计

连接相关的审计日志信息的格式如下所示。

具体的:

[2012-06-20 15:40:39]:审计的时间。

[CONNECT]:为连接的类型;

status:为连接成功(0)或者失败(错误号)的状态;

user:为连接的用户名;

external-user:为外部连接的用户,在使用中间件或者代理服务的时候有效;

proxy-user:为代理服务的用户名;

host:表示连接的主机名;

ip:连接的ip地址;

database:表示连接的数据库名。

[2012-06-20 15:40:39] [CONNECT] status: # ; thread_id: # ; user: XXX ; external-user: XXX ; proxy-user: XXX ; host: XXX ; ip: ###.###.###.### ; database: XXX

How do you handle database upgrades in MySQL?How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

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.

What are the different backup strategies you can use for MySQL?What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

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.

How do you optimize database schema design for performance in MySQL?How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

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.

How to use MySQL functions for data processing and calculationHow to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PM

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.

An efficient way to batch insert data in MySQLAn efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PM

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.

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

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.
