sysbench的安装和做性能测试

http://imysql.cn/node/312

sysbench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。

关于这个项目的详细介绍请看：http://sysbench.sourceforge.net。

它主要包括以下几种方式的测试：

1、cpu性能

2、磁盘io性能

3、调度程序性能

4、内存分配及传输速度

5、POSIX线程性能

6、数据库性能(OLTP基准测试)

目前sysbench主要支持 MySQL,pgsql,oracle 这3种数据库。

一、安装首先，在 http://sourceforge.net/projects/sysbench 下载源码包。

接下来，按照以下步骤安装：

tar zxf sysbench-0.4.8.tar.gz cd sysbench-0.4.8 ./configure && make && make install strip /usr/local/bin/sysbench

以上方法适用于 MySQL 安装在标准默认目录下的情况，如果 MySQL 并不是安装在标准目录下的话，那么就需要自己指定 MySQL 的路径了。

比如我的 MySQL 喜欢自己安装在 /usr/local/mysql 下，则按照以下方法编译：

/configure --with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib && make && make install

当然了，用上面的参数编译的话，就要确保你的 MySQL lib目录下有对应的 so 文件，

如果没有，可以自己下载 devel 或者 share 包来安装。

另外，如果想要让 sysbench 支持 pgsql/oracle 的话，

就需要在编译的时候加上参数 --with-pgsql 或者 --with-oracle 这2个参数默认是关闭的，只有 MySQL 是默认支持的。

二、开始测试编译成功之后，就要开始测试各种性能了，测试的方法官网网站上也提到一些，

但涉及到 OLTP 测试的部分却不够准确。在这里我大致提一下：

1、cpu性能测试

sysbench --test=cpu --cpu-max-prime=20000 run cpu测试主要是进行素数的加法运算，在上面的例子中，指定了最大的素数为 20000，

自己可以根据机器cpu的性能来适当调整数值。

2、线程测试

sysbench --test=threads --num-threads=64 --thread-yields=100 --thread-locks=2 run 3、磁盘IO性能测试

sysbench --test=fileio --num-threads=16 --file-total-size=3G --file-test-mode=rndrw prepare sysbench --test=fileio --num-threads=16 --file-total-size=3G --file-test-mode=rndrw run sysbench --test=fileio --num-threads=16 --file-total-size=3G --file-test-mode=rndrw cleanup

上述参数指定了最大创建16个线程，创建的文件总大小为3G，文件读写模式为随机读。

4、内存测试

sysbench --test=memory --memory-block-size=8k --memory-total-size=4G run

上述参数指定了本次测试整个过程是在内存中传输 4G 的数据量，每个 block 大小为 8K。

5、OLTP测试

sysbench --test=oltp --mysql-table-engine=myisam --oltp-table-size=1000000 / --mysql-socket=/tmp/mysql.sock --mysql-user=test --mysql-host=localhost / --mysql-password=test prepare

上述参数指定了本次测试的表存储引擎类型为 myisam，

这里需要注意的是，官方网站上的参数有一处有误，即 --mysql-table-engine，官方网站上写的是 --mysql-table-type，这个应该是没有及时更新导致的。

另外，指定了表最大记录数为 1000000，其他参数就很好理解了，主要是指定登录方式。

测试 OLTP 时，

可以自己先创建数据库 sbtest，或者自己用参数 --mysql-db 来指定其他数据库。

--mysql-table-engine 还可以指定为 innodb 等 MySQL 支持的表存储引擎类型。

好了，主要的就是这些了，想要了解更多信息就访问 sysbench 项目的主页吧

How does MySQL index cardinality affect query performance?Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL: Resources and Tutorials for New UsersApr 14, 2025 am 12:16 AM

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

Real-World MySQL: Examples and Use CasesApr 14, 2025 am 12:15 AM

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.

SQL Commands in MySQL: Practical ExamplesApr 14, 2025 am 12:09 AM

SQL commands in MySQL can be divided into categories such as DDL, DML, DQL, DCL, etc., and are used to create, modify, delete databases and tables, insert, update, delete data, and perform complex query operations. 1. Basic usage includes CREATETABLE creation table, INSERTINTO insert data, and SELECT query data. 2. Advanced usage involves JOIN for table joins, subqueries and GROUPBY for data aggregation. 3. Common errors such as syntax errors, data type mismatch and permission problems can be debugged through syntax checking, data type conversion and permission management. 4. Performance optimization suggestions include using indexes, avoiding full table scanning, optimizing JOIN operations and using transactions to ensure data consistency.

How does InnoDB handle ACID compliance?Apr 14, 2025 am 12:03 AM

InnoDB achieves atomicity through undolog, consistency and isolation through locking mechanism and MVCC, and persistence through redolog. 1) Atomicity: Use undolog to record the original data to ensure that the transaction can be rolled back. 2) Consistency: Ensure the data consistency through row-level locking and MVCC. 3) Isolation: Supports multiple isolation levels, and REPEATABLEREAD is used by default. 4) Persistence: Use redolog to record modifications to ensure that data is saved for a long time.

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

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

What are phantom reads and how does InnoDB prevent them (Next-Key Locking)?Apr 13, 2025 am 12:16 AM

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.
