现在的压力测试工具各种各样，只要上手好几款功能强大点的而且比较大众化的压力测试工具即可，以下跟大家交流下sysbench的安装和压力测试
　　sysbench支持以下几种测试模式：
　　1、CPU运算性能
　　2、磁盘IO性能
　　3、内存分配及传输速度
　　4、内存分配及传输速度
　　5、POSIX线程性能
　　6、数据库性能（OLTP基准测试）
　　目前sysbench主要支持mysql，drizzle，pgsql，oracle等几种数据库
　　下面安装sysbench
　　一、 下载源码包，安装epel包后以便安装bzr客户端：
　　[root ~]$ rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
　　Retrieving http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
　　warning: /var/tmp/rpm-tmp.wgHSDP: Header V3 DSA/SHA1 Signature， key ID 217521f6: NOKEY
　　Preparing...                ########################################### []
　　1:epel-release           ########################################### []
　　然后可以开始安装bzr客户端了：
　　以下安装报错了：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
