mysql压力测试---sysbench

一、sysbench简介

sysbench是一款开源的多线程性能测试工具，可以执行CPU/内存/线程/IO/数据库等方面的性能测试。数据库目前支持MySQL/Oracle/PostgreSQL。

二、sysbench安装

下载sysbench-0.4.12.tar.gz

tar -xvf sysbench-0.4.12.tar.gz

如果 MySQL 并不是安装在标准目录下的话，那么就需要自己指定 MySQL 的路径了。

编译安装：

./configure --with-mysql-includes=/usr/local/mysqlndb/include --with-mysql-libs=/usr/local/mysql/lib
make
make install

三、测试

测试分为prepare、run.

ndbcluster测试prepare  

sysbench --test=oltp --mysql-table-engine=ndbcluster --mysql-db=ndb --oltp-table-size=100 --mysql-user=root --mysql-password="" --mysql-socket=/usr/local/mysql/tmp/mysql.sock --db-driver=mysql --num-threads=16 prepare

手动自己写一个存储过程录入数据：

DELIMITER $$
DROP PROCEDURE test.wuxin_erp_insert $$
CREATE PROCEDURE test.wuxin_erp_insert()
BEGIN
DECLARE i INT;
SET i=0;
WHILE i< 100000 DO
REPLACE INTO ndb.sbtest SELECT i,0,‘‘,‘qqqqqqqqqqwwwwwwwwwweeeeeeeeeerrrrrrrrrrtttttttttt‘;
END WHILE;
COMMIT;
END$$
DELIMITER ;

录入数据：

call test.wuxin_erp_insert ();

分别测试线程说为8，16，32

下面以线程数量为8进行测试

并发线程数量：8
