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}"
