二、安装配置MySQL

1.下载安装

sudo apt install mysql-server
sudo apt install libmysql++-dev

2.修改用户名密码
log in mysql by password:

1. sudo cat /etc/mysql/debian.cnf
2. mysql -u debian-sys-maint -p
	ZSX5MbUDpyxCt9cS
3. mysql> set password for root@localhost = password('123'); 
4. mysql> update mysql.user set authentication_string=PASSWORD('123'), plugin='mysql_native_password' where user='root';
5. mysql> flush privileges;
6. sudo mysql -u root -p 
	123

3.修改工作目录（自己测试的分区）
Change mysql dir:

1. service mysql stop
2. sudo cp -arp /var/lib/mysql /data/       
3. sudo chown -R mysql:mysql /data/mysql
4. sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
	datadir=/data/mysql
5. sudo vim /etc/apparmor.d/usr.sbin.mysqld
	/data/mysql r
	/data/mysql/** rwk
6. /etc/init.d/apparmor restart
   /etc/init.d/mysql restart

三、tpcc运行

create databases and tables;

1. cd tpcc
2. sudo mysqladmin -u root -p create tpcc1000
3. sudo mysql -u root -p tpcc1000 < create_table.sql
4. sudo mysql -u root -p tpcc1000 < add_fkey_idx.sql

load data:

sudo ./tpcc_load -h 127.0.0.1 -d tpcc1000 -u root -p '123' -w 100

run:

sudo ./tpcc_start -h 127.0.0.1 -P 3306 -d tpcc1000 -u root -p 123 -w 10 -c 10 -r 120 -l 120 >> mysql_tpcc_20210517

四、自动化运行脚本

1.数据库自动删除

https://www.cnblogs.com/xpwi/p/9818751.html

2.注意：做文件系统压力测试时，比如按照10%递增，需要将上次load的数据库删除掉，重新以2倍的w数load，其中70个w大约有6.5G左右。

3.运行时如果需要清缓存可以运行脚本:

#!/bin/bash
while true
do
echo "drop_caches"
sudo echo 3 > /proc/sys/vm/drop_caches
sleep 1
sudo sync
sleep 1
done
