一、前期準備

　　1、寫指令碼刷資料

[root@computer opt]# vi slap.sh
#!/bin/bash
HOSTNAME="localhost"
PORT="3306"
USERNAME="root"
PASSWORD=""
DBNAME="oldboy"
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','oldboyedu')"
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}"
