一、安装

下载sysbench,当前最新版本是1.0.15

cd /tmp/install
wget /tupian/20230521/sysbench-1.0.15.zip -O "sysbench-1.0.15.zip"
unzip sysbench-1.0.15.zip
cd sysbench-1.0.15

执行安装

yum install automake libtool mysql-devel postgresql-devel –y
./autogen.sh
./configure --with-pgsql --with-pgsql-includes=/appdb/atlasdb/pg11beta2/include  --with-pgsql-libs=/appdb/atlasdb/pg11beta2/lib
make
make install 

安装成功

[root@localhost sysbench-1.0.15]# sysbench --version
sysbench 1.0.15

二、参数说明

通过sysbench --help命令可以查看详细的参数设置.

[root@localhost include]# 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]
...  

其中:
oltp-tables-count
生成测试数据表数量

--threads=N
sysbench使用的工作线程数

--time=N
执行时长,以秒为单位

--report-interval=N
报告间隔,以秒为单位

--config-file=FILENAME
配置文件

--db-driver=STRING
数据库驱动mysql/pgsql

pgsql options:
--pgsql-host=STRING PostgreSQL server host [localhost]
--pgsql-port=N PostgreSQL server port [5432]
--pgsql-user=STRING PostgreSQL user [sbtest]
--pgsql-password=STRING PostgreSQL password []
--pgsql-db=STRING PostgreSQL database name [sbtest]

三、基本使用

连接数据库,创建测试数据库sysbench

$createdb sysbench

准备阶段
执行以下命令,sysbench执行自带的测试脚本

sysbench /usr/local/share/sysbench/tests/include/oltp_legacy/oltp.lua \
--oltp-tables-count=10 --oltp-table-size=500000 \
--db-driver=pgsql --pgsql-host=192.168.26.103 --pgsql-port=5432 \
--pgsql-user=atlasdb --pgsql-db=sysbench \
prepare

命令输出

Creating table 'sbtest1'...
Inserting 500000 records into 'sbtest1'
Creating secondary indexes on 'sbtest1'...
Creating table 'sbtest2'...
Inserting 500000 records into 'sbtest2'
Creating secondary indexes on 'sbtest2'...
Creating table 'sbtest3'...
Inserting 500000 records into 'sbtest3'
Creating secondary indexes on 'sbtest3'...
Creating table 'sbtest4'...
Inserting 500000 records into 'sbtest4'
Creating secondary indexes on 'sbtest4'...
Creating table 'sbtest5'...
Inserting 500000 records into 'sbtest5'
Creating secondary indexes on 'sbtest5'...
Creating table 'sbtest6'...
Inserting 500000 records into 'sbtest6'
Creating secondary indexes on 'sbtest6'...
Creating table 'sbtest7'...
Inserting 500000 records into 'sbtest7'
Creating secondary indexes on 'sbtest7'...
Creating table 'sbtest8'...
Inserting 500000 records into 'sbtest8'
Creating secondary indexes on 'sbtest8'...
Creating table 'sbtest9'...
Inserting 500000 records into 'sbtest9'
Creating secondary indexes on 'sbtest9'...
Creating table 'sbtest10'...
Inserting 500000 records into 'sbtest10'
Creating secondary indexes on 'sbtest10'..

运行基准测试

sysbench /usr/local/share/sysbench/tests/include/oltp_legacy/oltp.lua \
--report-interval=5 \
--threads=4 --time=120 --db-driver=pgsql --pgsql-host=192.168.26.103 --pgsql-port=5432 \
--pgsql-user=atlasdb --pgsql-db=sysbench \
run

执行完毕,4线程的执行过程和结果如下:

sysbench 1.0.15 (using bundled LuaJIT 2.1.0-beta2)

Running the test with following options:
Number of threads: 4
Report intermediate results every 5 second(s)
