1、编译安装
下载源码包,解压缩,然后:
cp makefile.suite makefile
修改makefile文件中的CC、DATABASE、MACHINE、WORKLOAD等定义:
################ ## CHANGE NAME OF ANSI COMPILER HERE ################ CC = gcc # Current values for DATABASE are: INFORMIX, DB2, ORACLE, # SQLSERVER, SYBASE, TDAT (Teradata) # Current values for MACHINE are: ATT, DOS, HP, IBM, ICL, MVS, # SGI, SUN, U2200, VMS, LINUX, WIN32 # Current values for WORKLOAD are: TPCH DATABASE= MYSQL MACHINE = LINUX WORKLOAD = TPCH
修改tpcd.h文件,增加几行宏定义:
#ifdef MYSQL #define GEN_QUERY_PLAN "" #define START_TRAN "START TRANSACTION" #define END_TRAN "COMMIT" #define SET_OUTPUT "" #define SET_ROWCOUNT "limit %d;\n" #define SET_DBASE "use %s;\n" #endif
然后执行make编译,编译完毕后会生成两个可执行文件:
? dbgen:数据生成工具。在使用InfiniDB官方测试脚本进行测试时,需要用该工具生成tpch相关表数据。
? qgen:SQL生成工具
生成初始化测试数据:
#先把sql脚本模板拷贝到dbgen所在目录下 [root@imysql tpch]# cp -f queries/*.sql ./ [root@imysql tpch]# time ./dbgen -s 50 TPC-H Population Generator (Version 2.9.0) Copyright Transaction Processing Performance Council 1994 - 2008 real 192m43.897s user 37m45.398s sys 19m4.132s [root@imysql tpch]# ls -lh *tbl -rw-r--r-- 1 root root 1.2G Sep 21 15:23 customer.tbl -rw-r--r-- 1 root root 1.4G Sep 21 15:23 lineitem.tbl -rw-r--r-- 1 root root 2.2K Sep 21 15:23 nation.tbl -rw-r--r-- 1 root root 317M Sep 21 15:23 orders.tbl -rw-r--r-- 1 root root 504K Sep 21 15:23 partsupp.tbl -rw-r--r-- 1 root root 464K Sep 21 15:23 part.tbl -rw-r--r-- 1 root root 389 Sep 21 15:23 region.tbl -rw-r--r-- 1 root root 69M Sep 21 15:23 supplier.tbl
dbgen参数 -s 的作用是指定生成测试数据的仓库数,建议基准值设定在100以上,在我的测试环境中,一般都设定为1000。
由于源码包中自带的tpch初始化库表脚本并不能完全适用MySQL,需要修改部分代码。
先生成测试SQL脚本:
[root@imysql tpch]# ./qgen | sed -e 's/\r//' > queries/tpch_queries.sql
而后用vim打开tpch_queries.sql脚本,进行下面几次全局替换:
:%s/;\nlimit/ limit/g :%s/limit -1/limit 1/g
搜索所有类似下面的语句,去掉后面的 (3):
l_shipdate l_shipdate 修改第369行附近: count(o_orderkey) => count(o_orderkey) as c_count
修改第376行附近:
) as c_orders (c_custkey, c_count) => ) as c_orders
修改第431行附近:
drop view revenue0 limit 1; => drop view revenue0;
最后把大的查询SQL脚本拆分成23个独立的SQL查询脚本,分别从tpch_01.sql ~ tpch_23.sql。
2、初始化库表
tpch提供的数据库表初始化脚本有些小问题,需要进行修改:
dss.ddl – DSS库初始化DDL脚本
dss.ri – DSS数据表创建索引、外键脚本
dss.ddl脚本需要增加几行:
drop database tpch; create database tpch; use tpch;
dss.ri脚本需要修改几个地方:
修改第4行左右:
CONNECT TO TPCD; => Use tpch;
修改第6~13行,所有的SQL注释符 “--” 后面再加一个空格:
-- ALTER TABLE TPCD.REGION DROP PRIMARY KEY; -- ALTER TABLE TPCD.NATION DROP PRIMARY KEY; -- ALTER TABLE TPCD.PART DROP PRIMARY KEY; -- ALTER TABLE TPCD.SUPPLIER DROP PRIMARY KEY; -- ALTER TABLE TPCD.PARTSUPP DROP PRIMARY KEY; -- ALTER TABLE TPCD.ORDERS DROP PRIMARY KEY; -- ALTER TABLE TPCD.LINEITEM DROP PRIMARY KEY; -- ALTER TABLE TPCD.CUSTOMER DROP PRIMARY KEY;
修改第25行:
ADD FOREIGN KEY NATION_FK1 (N_REGIONKEY) references TPCD.REGION; => ADD FOREIGN KEY NATION_FK1 (N_REGIONKEY) references TPCD.REGION(R_REGIONKEY);
修改第40行:
ADD FOREIGN KEY SUPPLIER_FK1 (S_NATIONKEY) references TPCD.NATION; => ADD FOREIGN KEY SUPPLIER_FK1 (S_NATIONKEY) references TPCD.NATION(N_NATIONKEY);
修改第55行:
ADD FOREIGN KEY CUSTOMER_FK1 (C_NATIONKEY) references TPCD.NATION; => ADD FOREIGN KEY CUSTOMER_FK1 (C_NATIONKEY) references TPCD.NATION(N_NATIONKEY);
修改第73行:
ADD FOREIGN KEY PARTSUPP_FK1 (PS_SUPPKEY) references TPCD.SUPPLIER; => ADD FOREIGN KEY PARTSUPP_FK1 (PS_SUPPKEY) references TPCD.SUPPLIER(S_SUPPKEY);
修改第78行:
ADD FOREIGN KEY PARTSUPP_FK2 (PS_PARTKEY) references TPCD.PART; => ADD FOREIGN KEY PARTSUPP_FK2 (PS_PARTKEY) references TPCD.PART(P_PARTKEY);
修改第84行:
ADD FOREIGN KEY ORDERS_FK1 (O_CUSTKEY) references TPCD.CUSTOMER; => ADD FOREIGN KEY ORDERS_FK1 (O_CUSTKEY) references TPCD.CUSTOMER(C_CUSTKEY);
修改第90行:
ADD FOREIGN KEY LINEITEM_FK1 (L_ORDERKEY) references TPCD.ORDERS; => ADD FOREIGN KEY LINEITEM_FK1 (L_ORDERKEY) references TPCD.ORDERS(O_ORDERKEY);
修改第96行:
TPCD.PARTSUPP; => TPCD.PARTSUPP(PS_PARTKEY,PS_SUPPKEY);
另外,由于tpch生成的表名是大写的,需要修改下表名成小写的,因此再增加几行:
use tpch; alter table CUSTOMER rename to customer ; alter table LINEITEM rename to lineitem ; alter table NATION rename to nation ; alter table ORDERS rename to orders ; alter table PART rename to part ; alter table PARTSUPP rename to partsupp ; alter table REGION rename to region ; alter table SUPPLIER rename to supplier ;
3、导入数据
测试数据生成了,测试库表也初始化完了,接下来就可以开始导入数据了。
需要注意下,如果开启了binlog,在导入前最好先关闭binlog,否则会提示超出max_binlog_cache_size的错误提示,如果不能关闭binlog,则需要把导入文件切分成多个小文件再导入。
myqsl -e "LOAD DATA INFILE 'path/dbgen/customer.tbl' INTO TABLE CUSTOMER FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/orders.tbl' INTO TABLE ORDERS FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/lineitem.tbl' INTO TABLE LINEITEM FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/nation.tbl' INTO TABLE NATION FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/partsupp.tbl' INTO TABLE PARTSUPP FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/part.tbl' INTO TABLE PART FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/region.tbl' INTO TABLE REGION FIELDS TERMINATED BY '|';" myqsl -e "LOAD DATA INFILE 'path/dbgen/supplier.tbl' INTO TABLE SUPPLIER FIELDS TERMINATED BY '|';"
4、执行tpch测试
接下来就可以进行tpch测试了,逐个执行23个查询SQL脚本即可,每次执行前都要重启下MySQL实例,确保每次的内存缓冲区都是干净的。
简单循环测试脚本如下:
#!/bin/sh ## ## 执行tpch OLAP测试 ## ## writed by yejr(http://imysql.com), 2012/12/14 ## PATH=$PATH:/usr/local/bin export PATH . ~/.bash_profile > /dev/null 2>&1 exec 3>&1 4>&2 1>> tpch-benchmark-olap-`date +'%Y%m%d%H%M%S'`.log 2>&1 I=1 II=3 while [ $I -le $II ] do N=1 T=23 while [ $N -lt $T ] do if [ $N -lt 10 ] ; then NN='0'$N else NN=$N fi echo "query $NN starting" /etc/init.d/mysql restart time mysql -f tpch 附件:tpch初始化、自动化测试脚本压缩包。 备注:本文档部分参考古雷、王洪权整理的资料,感谢二位 :)

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

The key to installing MySQL elegantly is to add the official MySQL repository. The specific steps are as follows: Download the MySQL official GPG key to prevent phishing attacks. Add MySQL repository file: rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm Update yum repository cache: yum update installation MySQL: yum install mysql-server startup MySQL service: systemctl start mysqld set up booting
