一款MySQL自带的专用轻量压测工具：mysqlslap
--query：测试要执行的sql语句
--number-of-queries：指定测试要执行sql语句执行的请求数
-c,concurrency：指定测试执行请求的并行度
-i,--iterations：指定测试运行的次数
--create-schema：指定此次测试在哪个schema下执行
[mysql@mysql1 ~]$ mysqlslap -usystem -p123456 -S /data/mysqldata/3306/mysql.sock --query="select user,host from mysql.user" --number-of-queries=10000 -c 30 -i 10 --create-schema=mysql
模拟30个用户连接，共执行100万次请求
