1.0 之后的版本使用方法跟之前的有所区别，下面所有内容基于 1.0.9 版本。
另外，为了方便管理测试，最好不要通过命令直接运行测试，而是写成脚本自动化执行测试。
1. 安装及简介
Linux 各大发行版通过自带安装工具直接安装即可，RHEL/CentOS 的安装命令如下：
sudo yum -y install sysbenchsysbench 可以进行以下测试：
- CPU 运算性能测试
- 磁盘 IO 性能测试
- 调度程序性能测试
- 内存分配及传输速度测试
- POSIX 线程性能测试
- 数据库性能测试（OLTP 基准测试，需要通过
/usr/share/sysbench/目录中的 Lua 脚本执行，例如oltp_read_only.lua脚本执行只读测试）
另外，sysbench 还可以通过运行命令时指定自己的 Lua 脚本来自定义测试。

CPU 测试时，会计算素数（对这个数字除以 2 到这个数字平方根之间的所有数字来验证素数）直到某个指定值所需要的时间。单纯的测试一组非常有限 CPU 硬件性能。
CPU 基准测试时可以指定线程数量和素数上限。
先查看帮助信息：

使用 fileio 时，需要创建一组测试文件，测试文件需要大于可用内存的大小，避免文件缓存在内存中影响结果。测试流程为：准备测试文件-》测试-》回收测试文件，命令如下：
# sysbench --file-total-size=28G fileio prepare
# sysbench --file-total-size=28G --file-test-mode=rndrw --time=300 --max-requests=0 fileio run
# sysbench --file-total-size=28G fileio cleanup对于 I/O 基准测试，可以通过 --file-test-mode 告诉 sysbench 要运行的工作负载的类型，可用类型有：
- seqwr：顺序写入
- seqrewr：顺序重写
- seqrd：顺序读取
- rndrd：随机读取
- rndwr：随机写入
- rndrw：随机读取/写入
上面的例子中使用的是随机读取/写入（rndrw）。通过 --time 选项指定测试持续时间（以秒为单位）。

Removing test files...2.4 测试 memory
当在 sysbench 中进行内存测试时，会分配一个内存缓冲区并在此执行读写操作，每次操作都会读完或写满缓冲区。然后重复此操作直到达到指定大小（--memory-total-size）。可以提供多个线程（--threads），不同的缓冲区大小（--memory-block-size）和请求类型（读或写，顺序或随机）。

测试 threads 时，每个工作线程将被分配一个 mutex（一种锁）。每次执行时，每个线程将循环若干次（通过 --thread-yields 的数量设置），循环时这个线程会锁定，在再次执行时解锁。
通过调整各种参数，可以模拟具有单个或多个锁的高并发线程下的情况。

测试 mutex 时，sysbench 将为每个线程运行一个请求。这个请求首先会对 CPU 施加一些压力（使用一个简单的增量循环，通过 --mutex-loops 参数设置），然后随机使用一个 mutex（锁），递增一个全局变量并再次释放锁。这个过程根据锁的个数（--mutex-locks）多次重复。随机 mutex 取自大小为 --mutex-num 的参数池。

OLTP 基准测试模拟了一个简单的事务处理系统的工作负载。然而最新版本的 sysbench 把 OLTP 这个曾经的內建测试类型移除了，如果要用，需要在命令中指定测试类型的位置用 /usr/share/sysbench/oltp_read_only.lua 脚本代替测试类型。
流程：指定数据库-》建表并生成数据-》运行测试-》清理测试表。
首先生成表，注意替换命令中的数据库密码和 MySQL 套接字，如果 MySQL 安装在默认位置，可以去掉 --mysql-socket 选项：
sysbench --db-driver=mysql --mysql-user=root --mysql-password=<pwd>
--mysql-socket=<mysql.sock path> --mysql-db=foo --range_size=100
--table_size=10000 --tables=2 --threads=2 --events=0 --time=60
--rand-type=uniform /usr/share/sysbench/oltp_read_only.lua prepare运行测试，指定了 2 个并发线程，：
sysbench --db-driver=mysql --mysql-user=root --mysql-password=<pwd>
--mysql-socket=<mysql.sock path> --mysql-db=foo --range_size=100
--table_size=10000 --tables=2 --threads=2 --events=0 --time=60
--rand-type=uniform /usr/share/sysbench/oltp_read_only.lua run清理测试时生成的测试表：
sysbench --db-driver=mysql --mysql-user=root --mysql-password=<pwd>
