一、模拟数据库数据

1-1 创建数据库及表脚本&n【文章出处:国外服务器http://www.558idc.com 转发请说明出处】bsp;- 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
