  • mysqlslap 使用总结

    mysqlslap 可以用于模拟服务器的负载，并输出计时信息。其被包含在 MySQL 5.1 的发行包中。测试时，可以指定并发连接数，可以指定 SQL 语句。如果没有指定 SQL 语句，mysqlslap 会自动生成查询 schema 的 SELECT 语句。

    6. 使用 --only-print 选项，可以查看 mysqlslap 在测试过程中如何执行的 sql 语句。在这种方式下，仅会对数据库进行模拟操作。如下显示的自动产生测试表和数据的情况下，mysqlslap 的执行过程： 创建一个临时的库 mysqlslap ，并在测试结束是会将其删除。

      1 [root@davy libmysql]# mysqlslap -a --only-print

    7. 实际测试中的复杂情况。
    使用 --defaults-file 选项，指定从配置文件中读取选项配置。
    使用 --number-int-cols 选项，指定表中会包含 4 个 int 型的列。
    使用 --number-char-cols 选项，指定表中会包含 35 个 char 型的列。
    使用 --engine 选项，指定针对何种存储引擎进行测试。

    mysqlslap 运行分三个阶段:
    创建 schema，table 和任何用来测试的已经存储了的程序和数据。这个阶段使用单客户端连接；
    进行负载测试。这个阶段使用多客户端连接；
    清除（断开连接，删除指定表）。这个阶段使用单客户端连接。

    例子：

    a. 提供你自己的创建 SQL 语句和查询 SQL 语句，有 50 个客户端查询，每个查询 200 次（在单行上输入命令）： 

    1 [root@davy ~]# mysqlslap --delimiter=";" --create="CREATE TABLE a (b int);INSERT INTO a VALUES (23)" --query="SELECT * FROM a" --concurrency=50 --iterations=200
2 Benchmark
3 Average number of seconds to run all queries: 0.005 seconds
4 Minimum number of seconds to run all queries: 0.003 seconds
5 Maximum number of seconds to run all queries: 0.007 seconds
6 Number of clients running queries: 50
7 Average number of queries per client: 1

    b. 让 mysqlslap 创建查询的 SQL 语句，使用的表有 2 个 INT 行和 3 个 VARCHAR 行。使用 5 个客户端，每一个查询 20 次！不要创建表或插入数据。(换言之，用之前测试的模式和数据): 

    1 [root@davy ~]# mysqlslap --concurrency=5 --iterations=20 --number-int-cols=2 --number-char-cols=3 --auto-generate-sql
2 
3 Benchmark
4 Average number of seconds to run all queries: 0.025 seconds
5 Minimum number of seconds to run all queries: 0.012 seconds
6 Maximum number of seconds to run all queries: 0.084 seconds
7 Number of clients running queries: 5
8 Average number of queries per client: 0

    c. 告诉程序从指定的 create.sql 文件去加载 create，insert 和查询等 SQL 语句。该文件有多个表的 create 和insert 语句, 它们都是通过“；”分隔开的。query.sql 文件则有 多个查询语句, 分隔符也是“；”。执行所有的加载语句，然后通过查询文件执行所有的查询语句，分别在 5 个客户端上每个执行 5 次：

    1 [root@Betty ~]# mysqlslap --concurrency=5 --iterations=5 --query=query.sql --create=create.sql --delimiter=";"

    mysqlslap 对于模拟多个用户同时对 MySQL 发起“进攻”提供了方便。同时详细的提供了“高负荷攻击 MySQL”的详细数据报告。
