MySQL基于索引的压力测试的实现

一、模拟数据库数据

1-1 创建数据库及表脚本 - vim slap.sh

#!/bin/bash  
HOSTNAME="localhost"
PORT="3306"
USERNAME="root"
PASSWORD="123"
DBNAME="testdb"
TABLENAME="t1"
#create database
mysql -h ${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} -e "drop database if exists ${DBNAME}"
create_db_sql="create database if not exists ${DBNAME}"
mysql -h ${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} -e "${create_db_sql}"
#create table
create_table_sql="create table if not exists ${TABLENAME}(stuid int not null primary key,stuname varchar(20) not null,stusex char(1)  
not null,cardid varchar(20) not null,birthday datetime,entertime datetime,address varchar(100)default null)"
mysql -h ${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${create_table_sql}"
#insert data to table
i="1"
while [ $i -le 500000 ]  
do  
insert_sql="insert into ${TABLENAME}  values($i,'alexsb_$i','1','110011198809163418','1990-05-16','2017-09-13','testdb')"
mysql -h ${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${insert_sql}"
let i++  
done  
#select data  
select_sql="select count(*) from ${TABLENAME}"
mysql -h ${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"

1-2 执行脚本 

sh slap.sh

1-3 检查数据的可用性

mysql -uroot -p123
select count(*) from testdb.t1;

1-4 在索引优化前后使用mysqlslap进行压力测试

mysqlslap --defaults-file=/etc/my.cnf \
--concurrency=100 --iterations=1 --create-schema='testdb' \
--query="select * from testdb.t1 where stuname='test_100'" engine=innodb \
--number-of-queries=2000 -uroot -p123 -verbose
