sysbench压测工具操作文档
sysbench是一个基于 LuaJIT 的可编写脚本的多线程基准测试工具。它最常用于数据库基准测试，但也可用于创建不涉及数据库服务器的任意复杂工作负载
一、安装sysbench
1.1、借助包管理器安装
- Debian/Ubuntu
curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.deb.sh | sudo bash
apt -y install sysbench
- RHEL/CentOS
curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
yum -y install sysbench
- Fedora
curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
dnf -y install sysbench
- Arch Linux
pacman -Suy sysbench
1.2、源码编译安装
以CentOS系统为例
yum install gcc gcc-c++ autoconf automake make libtool mysql-devel git mysql
git clone https://github.com/akopytov/sysbench.git
##从Git中下载Sysbench
cd sysbench
##打开sysbench目录
git checkout 1.0.18
##切换到sysbench 1.0.18版本
./autogen.sh
##运行autogen.sh
./configure --prefix=/usr --mandir=/usr/share/man
make
##编译
make install

帮助文档
sysbench --help
Usage:
sysbench [options]... [testname] [command]
Commands implemented by most tests: prepare run cleanup help
General options:
--threads=N number of threads to use [1];创建测试线程的数目。默认为1
--events=N limit for total number of events [0];请求的最大数目,0代表不限制
--time=N limit for total execution time in seconds [10];最大执行时间，单位是s。默认是10s
--forced-shutdown=STRING number of seconds to wait after the --time limit before forcing shutdown, or 'off' to disable [off];过max-time强制中断。默认是off
--thread-stack-size=SIZE size of stack per thread [64K];每个线程的堆栈大小。默认是64K
--rate=N average transactions rate. 0 for unlimited rate [0]
--report-interval=N periodically report intermediate statistics with a specified interval in seconds. 0 disables intermediate reports [0];指定每多少秒在屏幕上输出一次结果
--report-checkpoints=[LIST,...] dump full statistics and reset all counters at specified points in time. The argument is a list of comma-separated values representing the amount of time in seconds elapsed from start of test when report checkpoint(s) must be performed. Report checkpoints are off by default. []
--debug[=on|off] print more debugging info [off];是否显示更多的调试信息。默认是off
--validate[=on|off] perform validation checks where possible [off];在可能情况下执行验证检查。默认是off
--help[=on|off] print help and exit [off]
--version[=on|off] print version and exit [off]
--config-file=FILENAME File containing command line options
--tx-rate=N deprecated alias for --rate [0]
--max-requests=N deprecated alias for --events [0]
--max-time=N deprecated alias for --time [0]
--num-threads=N deprecated alias for --threads [1]
Pseudo-Random Numbers Generator options:;随机数选项
--rand-type=STRING random numbers distribution {uniform,gaussian,special,pareto} [special];默认情况下使用的随机数分布 {uniform, gaussian, special, pareto, zipfian}
--rand-spec-iter=N number of iterations used for numbers generation [12];特殊分布的迭代次数
--rand-spec-pct=N percentage of values to be treated as 'special' (for special distribution) [1];“特殊”值将落入特殊分布的整个范围的百分比
--rand-spec-res=N percentage of 'special' values to use (for special distribution) [75];用于特殊分布的“特殊”值的百分比
--rand-seed=N seed for random number generator. When 0, the current time is used as a RNG seed. [0];随机数生成器的种子。为 0 时，当前时间用作 RNG 种子
--rand-pareto-h=N parameter h for pareto distribution [0.2];帕累托分布的形状参数
Log options:
--verbosity=N verbosity level {5 - debug, 0 - only critical messages} [3]
--percentile=N percentile to calculate in latency statistics (1-100). Use the special value of 0 to disable percentile calculations [95]
--histogram[=on|off] print latency histogram in report [off]
General database options:
--db-driver=STRING specifies database driver to use ('help' to get list of available drivers) [mysql]
--db-ps-mode=STRING prepared statements usage mode {auto, disable} [auto]
--db-debug[=on|off] print database-specific debug information [off]
Compiled-in database drivers:
mysql - MySQL driver
mysql options:
--mysql-host=[LIST,...] MySQL server host [localhost]
--mysql-port=[LIST,...] MySQL server port [3306]
--mysql-socket=[LIST,...] MySQL socket
--mysql-user=STRING MySQL user [sbtest]
--mysql-password=STRING MySQL password []
--mysql-db=STRING MySQL database name [sbtest]

--mysql-compression[=on|off] use compression, if available in the client library [off]
--mysql-debug[=on|off] trace all client library calls [off]
--mysql-ignore-errors=[LIST,...] list of errors to ignore, or "all" [1213,1020,1205]
--mysql-dry-run[=on|off] Dry run, pretend that all MySQL client API calls are successful without executing them [off]
Compiled-in tests:
fileio - File I/O test
cpu - CPU performance test
memory - Memory functions speed test
threads - Threads subsystem performance test
mutex - Mutex performance test
See 'sysbench <testname> help' for a list of options for each test.
一般用法
sysbench 的一般命令行语法是
sysbench [options]... [testname] [command]
- options：部分包括测试需要的各种选项，有全局的也有每个测试模式自由的选项
- testname：指定测试类型，基本类型有fileio，cpu，memory，threads，mutex，oltp(或者指定lua脚本)
- command：控制命令
- prepare：为需要它们的测试执行准备操作，例如在磁盘上为测试创建必要的文件fileio，或为数据库基准填充测试数据库
- run：运行用testname参数指定的实际测试
- cleanup：清除准备阶段生成的测试数据
- help：显示使用testname参数指定的测试的使用信息
