使用数据库的压测工具super-smack测试mysql数据库性能

一、下载

 

super-smack

 

下载地址：http://vegan.net/tony/supersmack/

 

源码：http://vegan.net/tony/supersmack/super-smack-1.3.tar.gz

 

二、编译及安装

 

配置编译选项：./configure --prefix=/usr/local/super-smack-1.3 --with-mysql --with-smacks-dir=/usr/local/super-smack-1.3

 

请根据测试的数据库来选择 --with-pgsql --with-oracle　或　--with-mysql

 

重点说明一下--with-mysql的编译配置：

 

编译的时候要把/usr/lib64目录下的libmysqlclient.so.16放到/usr/lib目录下，否则会出现下面的错误：

 

configure: error: Could not find libmysqlclient in ' /usr/lib /usr/lib/mysql                    /usr/local/lib /usr/local/lib/mysql                    /usr/local/mysql/lib

 

configure: error: Could not find mysql.h in ' /usr/include /usr/include/mysql                        /usr/local/include /usr/local/include/mysql                        /usr/local/mysql/include'

 

由于我的mysql是自行编译的，所以我这样操作

 

cd /usr/include; ln -s /usr/local/mysql/include/mysql

 

cd /usr/lib; ln -s /usr/local/mysql/lib/mysql

 

编译及安装：

make;make install

 

三、使用方法及常见问题

 

为方便使用

 

ln -s /usr/local/super-smack/bin/super-smack /usr/local/bin/

 

ln -s /usr/local/super-smack/bin/gen-data /usr/local/bin/

 

使用方法：

 

cd /usr/lib;ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.16.0.0 libmysqlclient.so.16

 

或者

 

cd /usr/lib;cp -a /usr/local/mysql/lib/mysql/libmysqlclient.so.16.0.0 libmysqlclient.so.16

 

否则会有如下问题：

 

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

 

super-smack: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory

 

注意可能要根据实际情况修改select-key.smack文件中数据库连接部分的配置。

 

注意还需要指定select-key.smack 文件的具体位置，否则会出现下面的错误提示。

 

# super-smack select-key.smack 10 1000

 

super-smack: Could not open input file select-key.smack errno = 2, error is No such file or directory

 

四、正常使用的范例

 

[root@MySQL lib]# super-smack -d mysql /usr/local/super-smack/select-key.smack 10 1000       

 

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'

 

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

 

Table http_auth is now ready for the test

注意，本文只是抛砖引玉，实际测试中，根据实际情况，需要认真构造测试脚本。
