yum -y install make automake libtool pkgconfig libaio-develgithub下载：
https://github.com/akopytov/s...
解压：
tar -zxvf sysbench-1.0.14.tar.gz进入解压后的目录，安装：
cd /data/sysbench-1.0.14
./autogen.sh
# Add --with-pgsql to build with PostgreSQL support
./configure

如何使用命令
初接触该工具最好先看看帮助，学习如何使用sysbench命令。sysbench --help
Usage:
sysbench [options]... [testname] [command]上面显示，sysbench命令后面依次跟选项、测试名、命令
选项options
其中，常用的选项有：
mysql相关的选项（通过sysbench --help能找到）：
--db-driver=mysql # 数据库类型
--mysql-host=localhost # 数据库主机
--mysql-port=3306 # 数据库端口
--mysql-user=root # 登录名
--mysql-password=Root@1234 # 登录密码
--mysql-db=test # 测试数据库名称通用的选项：
| Option | Description | Default value |
|---|---|---|
--threads |
The total number of worker threads to create | 1 |
--events |
Limit for total number of requests. 0 (the default) means no limit | 0 |
--time |
Limit for total execution time in seconds. 0 means no limit | 10 |
--warmup-time |
Execute events for this many seconds with statistics disabled before the actual benchmark run with statistics enabled. This is useful when you want to exclude the initial period of a benchmark run from statistics. In many benchmarks, the initial period is not representative because CPU/database/page and other caches need some time to warm up | 0 |
--rate |
Average transactions rate. The number specifies how many events (transactions) per seconds should be executed by all threads on average. 0 (default) means unlimited rate, i.e. events are executed as fast as possible | 0 |
--thread-init-timeout |
Wait time in seconds for worker threads to initialize | 30 |
--thread-stack-size |
Size of stack for each thread | 32K |
--report-interval |
Periodically report intermediate statistics with a specified interval in seconds. Note that statistics produced by this option is per-interval rather than cumulative. 0 disables intermediate reports | 0 |
--debug |
Print more debug info | off |
--validate |
Perform validation of test results where possible | off |
--help |
Print help on general syntax or on a specified test, and exit | off |
--verbosity |
Verbosity level (0 - only critical messages, 5 - debug) | 4 |
--percentile |
sysbench measures execution times for all processed requests to display statistical information like minimal, average and maximum execution time. For most benchmarks it is also useful to know a request execution time value matching some percentile (e.g. 95% percentile means we should drop 5% of the most long requests and choose the maximal value from the remaining ones). This option allows to specify a percentile rank of query execution times to count | 95 |
--luajit-cmd |
perform a LuaJIT control command. This option is equivalent to luajit -j. See LuaJIT documentation for more information |
控制生成测试数据时，如何生成随机数的选项：
| Option | Description | Default value |
|---|---|---|
--rand-type |
random numbers distribution {uniform, gaussian, special, pareto, zipfian} to use by default. Benchmark scripts may choose to use either the default distribution, or specify it explictly, i.e. override the default. | special |
--rand-seed |
seed for random number generator. When 0, the current time is used as an RNG seed. | 0 |
--rand-spec-iter |
number of iterations for the special distribution | 12 |
--rand-spec-pct |
percentage of the entire range where 'special' values will fall in the special distribution | 1 |
--rand-spec-res |
percentage of 'special' values to use for the special distribution | 75 |
--rand-pareto-h |
shape parameter for the Pareto distribution | 0.2 |
--rand-zipfian-exp |
shape parameter (theta) for the Zipfian distribution | 0.8` |
测试名testname
sysbench有如下测试可供使用：
内置的测试：:
| 测试名 | 描述 |
|---|---|
| fileio | File I/O test |
| cpu | CPU performance test |
| memory | Memory functions speed test |
| threads | Threads subsystem performance test |
| mutex | Mutex performance test |
还有一些oltp（在线事务处理）相关的测试脚本可以在github上找到（https://github.com/akopytov/s...）。由于安装sysbench后已经有这些脚本了，我们只需要在sysbench中用这些脚本的名称即可。
oltp相关的测试：:
| 测试名 | 描述 |
|---|---|
| bulk_insert | - |
| empty-test | - |
| oltp_common | - |
| oltp_delete | - |
| oltp_insert | - |
| oltp_point_select | - |
| oltp_read_only | - |
| oltp_read_write | - |
| oltp_update_index | - |
| oltp_update_non_index | - |
| oltp_write_only | - |
| prime-test | - |
select_random_points
select_random_ranges
命令command
sysbench --help中已经说得很清楚了：
Commands implemented by most tests: prepare run cleanup help| 命令 | 描述 |
|---|---|
| prepare | - |
| run | - |
| cleanup | - |
| help | - |
注意，help命令跟sysbench --help两者是不一样的。--help是sysbench命令的选项。这里的help命令可以帮助我们了解测试的用法。
例如：
[root@betacat data]# sysbench oltp_read_write help
sysbench 1.0.14 (using bundled LuaJIT 2.1.0-beta2)
oltp_read_write options:
--distinct_ranges=N Number of SELECT DISTINCT queries per transaction [1]
--sum_ranges=N Number of SELECT SUM() queries per transaction [1]
--skip_trx[=on|off] Don't start explicit transactions and execute all queries in the AUTOCOMMIT mode [off]
--secondary[=on|off] Use a secondary index in place of the PRIMARY KEY [off]
--create_secondary[=on|off] Create a secondary index in addition to the PRIMARY KEY [on]
--index_updates=N Number of UPDATE index queries per transaction [1]
--range_size=N Range size for range SELECT queries [100]
--auto_inc[=on|off] Use AUTO_INCREMENT column as Primary Key (for MySQL), or its alternatives in other DBMS. When disabled, use client-generated IDs [on]
--delete_inserts=N Number of DELETE/INSERT combinations per transaction [1]
--tables=N Number of tables [1]
--mysql_storage_engine=STRING Storage engine, if MySQL is used [innodb]
--non_index_updates=N Number of UPDATE non-index queries per transaction [1]
--table_size=N Number of rows per table [10000]
--pgsql_variant=STRING Use this PostgreSQL variant when running with the PostgreSQL driver. The only currently supported variant is 'redshift'. When enabled, create_secondary is automatically disabled, and delete_inserts is set to 0
--simple_ranges=N Number of simple range SELECT queries per transaction [1]
--order_ranges=N Number of SELECT ORDER BY queries per transaction [1]
--range_selects[=on|off] Enable/disable all range SELECT queries [on]
--point_selects=N Number of point SELECT queries per transaction [10]
