SysBench系统性能基准测试工具

一。简介

SysBench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。

当前功能允许测试的系统参数有：

file I/O performance （文件I / O性能）

scheduler performance （调度性能）

memory allocation and transfer speed （内存分配和传输速度）

POSIX threads implementation performance （POSIX线程执行绩效）

database server performance (OLTP benchmark) （数据库服务器性能）

SysBench运行指定数目的线程，他们都是并行的执行请求。实际工作量的请求产生依赖于指定的测试模式（在编译中添加测试模块）。可以限制请求总数或总时间为基准，或两者。

二。安装

下载地址：

# wget http://nchc.dl.sourceforge.net/project/sysbench/sysbench/0.4.12/sysbench-0.4.12.tar.gz

# tar zxvf sysbench-0.4.12.tar.gz -C ../software/

# ./configure --prefix=/usr/local/sysbench-0.4.12 \

--with-mysql-includes=/usr/local/mysql-5.5.8/include \

--with-mysql-libs=/usr/local/mysql-5.5.8/lib

# make

# make install

安装过程中出现的错误以及解决办法：

问题一：

../libtool: line 838: X--tag=CC: command not found

../libtool: line 871: libtool: ignoring unknown tag : command not found

../libtool: line 838: X--mode=link: command not found

../libtool: line 1004: *** Warning: inferring the mode of operation is deprecated.: command not found

../libtool: line 1005: *** Future versions of Libtool will require --mode=MODE be specified.: command not found

../libtool: line 2231: X-g: command not found

../libtool: line 2231: X-O2: command not found

../libtool: line 1951: X-L/usr/local/mysql-5.5.8/lib: No such file or directory

../libtool: line 2400: Xsysbench: command not found

解决办法：

1.在编译前先运行autogen.sh即可。

2.安装新版本的libtool工具。

问题二：

./sysbench: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory

解决办法：

# in -s /usr/local/mysql-5.5.8/lib/libmysqlclient.so.16 /lib64/libmysqlclient.so.16
