mysql smack_super-smack测试mysql性能

super-smack测试mysql性能

一.使用Red Hat Enterprise Linux Server release 5.4，x86_64位系统

二.环境安装

1.所需软件mysql5.1.38,super-smack1.3.tar.gz

2.解压super-smack1.3.tar.gz，./configure --with-mysql=/data/mysql,config过程会出现找不到libmysqlclient.so文件，系统使用的64位lib库文件,需要做个软连接

#locate libmysqlclient.so

#ln -s /usr/lib64/libmysqlclient.so /usr/lib/

make过程中提示如下错误

query.cc:200: error: cast from 'char*' to 'unsigned int' loses precision

query.cc:200: error: cast from 'char*' to 'unsigned int' loses precision

query.cc:219: error: cast from 'char*' to 'unsigned int' loses precision

query.cc:219: error: cast from 'char*' to 'unsigned int' loses precision

修改super-smack-1.3/src目录下的query.cc

把200和219行的 unsigned 改成 long

重新make && make install

三.使用super-smack

1.#./super-smack -d mysql select-key-mysql.smack 10 1000

提示错误信息如下：

Error running query select count(*) from http_auth:Table 'test.http_auth' doesn't exist

Creating table 'http_auth'

Populating data file '/var/smack-data/words.dat' with shell command 'gen-data -n 90000 -f %12-12s%n,%25-25s,%n,%d'

sh: /var/smack-data/words.dat: No such file or directory

super-smack: Error generating data file errno = 2, error is No such file or directory

#编辑select-key.smack，如下

(1)把两处mysql.sock路径改成mysql安装的实际路径

(2)把两处words.dat改成http_auth.dat

(3)把gen-data -n 90000 -f %12-12s%n,%25-25s,%n,%d这行的逗号,换成空格即可(看网上朋友说把逗号换成空格不行，经本次测试可以使用空格)

(4)把delim "，"; 逗号提换成空格

修改完毕，保存

2.super-smack 执行过程中，可以创建http_auth表，但不能自动把数据导入到库中，原因不详，手动把数据导入到http_auth.dat文件中

#mkdir -p /var/smack-data/

#cp super-smack-1.3/smacks/* /usr/local/bin/

#./gen-data -n 90000 -f %12-12s%n %25-25s %n %d > /var/smack-data/http_auth.dat

3.执行，结果如下(myISAM表测试)

#./super-smack -d mysql smacks/select-key.smack 10 1000

Table 'http_auth' does not meet condtions, will be dropped

Creating table 'http_auth'

Loading data from file '/var/smack-data/http_auth.dat' into table 'http_auth'

Table http_auth is now ready for the test

Query Barrel Report for client smacker1

connect: max=5ms  min=1ms avg= 2ms from 10 clients

Query_type      num_queries     max_time        min_time        q_per_s

select_index    20000   0       0       14947.59

4.执行，结果如下(innodb表测试)

#.alter table http_auth engine=innodb;

#./super-smack -d mysql smacks/select-key.smack 10 1000

Query Barrel Report for client smacker1

connect: max=35ms  min=0ms avg= 14ms from 10 clients

Query_type      num_queries     max_time        min_time        q_per_s

select_index    20000   0       0       14760.01

注：1.-d指明是mysql数据库测试,然后指明测试文件,10表示10个线程，1000表示每个线程有1000个查询，q_per_s表示每秒钟查询记录。

2.update-select.smack测试，和select-key.smack修改的地方一样
