性能测试工具sysbench简介
出处信息
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。本文只是简单演示一下几种测试的用法，后续准备利用sysbench来对MySQL进行一系列的测试。具体的一些参数设置，需要根据不同的测试要求来进行调整。

编译安装
默认支持MySQL，如果需要测试Oracle/PostgreSQL，则在configure时需要加上-with-oracle或者-with-pgsql参数
以下是引用片段：
./configure --prefix=/u01/sysbench
--with-mysql-includes=/opt/mysql/include/mysql
--with-mysql-libs=/opt/mysql/lib/mysql
make && make install
