篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了sysbench-系统数据库压力测试工具相关的知识,希望对你有一定的参考价值。
sysbench是一款简单易用的压力测试工具,可以测试cpu,memory,fileio,mysql数据库;
sysbench安装方法:
默认的epel源中的sysbench是0.4版本的,现在已经到1.x版本,本主采用1.x版本
github-->https://github.com/akopytov/sysbench
centos安装方法:
#curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash #sudo yum -y install sysbench
安装完成后重要的文件:
对数据库压力测试的文件:
/usr/share/sysbench/bulk_insert.lua
/usr/share/sysbench/oltp_common.lua
/usr/share/sysbench/oltp_delete.lua #数据库删除测试文件
/usr/share/sysbench/oltp_insert.lua #数据库插入测试文件
/usr/share/sysbench/oltp_point_select.lua
/usr/share/sysbench/oltp_read_only.lua #数据库读测试文件
/usr/share/sysbench/oltp_read_write.lua#数据库读写测试文件
/usr/share/sysbench/oltp_update_index.lua
/usr/share/sysbench/oltp_update_non_index.lua
/usr/share/sysbench/oltp_write_only.lua #数据库写测试文件
/usr/share/sysbench/select_random_points.lua
/usr/share/sysbench/select_random_ranges.lua
开始数据库测试:
数据库测试分为3步:prepare(准备测试数据),run(开始测试),cleanup(清除测试数据)
用到的相关参数:
--db-driver=mysql
--mysql-host=localhost
--mysql-port=3306
--mysql-socket=/tmp/mysql.sock
--mysql-user=root
--mysql-password=123456
--mysql-db=sysbench
--tables=10
--table-size=500000
--report-interval=10
--time=120
--threads=50
参数解析:
--db-driver:用到的数据库类型
--mysql-host:数据库的IP
--mysql-port:数据库的端口
--mysql-socket:socket的路径
--mysql-user:数据库用户名
--mysql-password:用户密码
--mysql-db:数据库名字,默认为sysbench,需要提前创建创好
--tables:生成表的个数
--table-size:每个表的行数
--report-interval:每隔多久在屏幕打印一次信息
--time:压测时间
--threads:启动多少个线程,即模拟多少个用户
准备测试数据:
sysbench /usr/share/sysbench/oltp_read_only.lua --db-driver=mysql --mysql-host=localhost --mysql-port=3306 --mysql-socket=/tmp/mysql.sock --mysql-user=root --mysql-password=123456 --mysql-db=sysbench --tables=10 --table-size=500000 --report-interval=10 --time=120 --threads=50 prepare
压测数据库:
#读测试 sysbench /usr/share/sysbench/oltp_read_only.lua --db-driver=mysql --mysql-host=localhost --mysql-port=3306 --mysql-socket=/tmp/mysql.sock --mysql-user=root --mysql-password=123456 --mysql-db=sysbench --tables=10 --table-size=500000 --report-interval=10 --time=120 --threads=50 run #读写测试 sysbench /usr/share/sysbench/oltp_read_write.lua --db-driver=mysql --mysql-host=localhost --mysql-port=3306 --mysql-socket=/tmp/mysql.sock --mysql-user=root --mysql-password=123456 --mysql-db=sysbench --tables=10 --table-size=500000 --report-interval=10 --time=120 --threads=50 run #其它诊次类推 #读测试结果,模拟320个用户 [ 11s ] thds: 320 tps: 242.69 qps: 4209.17 (r/w/o: 3694.35/0.00/514.83) lat (ms,95%): 1678.14 err/s: 0.00 reconn/s: 0.00 [ 21s ] thds: 320 tps: 187.49 qps: 2996.82 (r/w/o: 2621.44/0.00/375.38) lat (ms,95%): 2120.76 err/s: 0.00 reconn/s: 0.00 [ 31s ] thds: 320 tps: 229.77 qps: 3649.12 (r/w/o: 3190.18/0.00/458.94) lat (ms,95%): 2159.29 err/s: 0.00 reconn/s: 0.00 [ 41s ] thds: 320 tps: 259.54 qps: 4175.73 (r/w/o: 3656.75/0.00/518.98) lat (ms,95%): 1803.47 err/s: 0.00 reconn/s: 0.00 [ 51s ] thds: 320 tps: 276.39 qps: 4406.96 (r/w/o: 3853.68/0.00/553.28) lat (ms,95%): 1589.90 err/s: 0.00 reconn/s: 0.00 [ 61s ] thds: 320 tps: 281.21 qps: 4496.82 (r/w/o: 3934.29/0.00/562.53) lat (ms,95%): 1561.52 err/s: 0.00 reconn/s: 0.00 [ 71s ] thds: 320 tps: 276.10 qps: 4435.70 (r/w/o: 3883.80/0.00/551.90) lat (ms,95%): 1648.20 err/s: 0.00 reconn/s: 0.00 [ 81s ] thds: 320 tps: 275.19 qps: 4392.43 (r/w/o: 3841.85/0.00/550.58) lat (ms,95%): 1618.78 err/s: 0.00 reconn/s: 0.00 [ 91s ] thds: 320 tps: 280.39 qps: 4491.68 (r/w/o: 3931.19/0.00/560.48) lat (ms,95%): 1589.90 err/s: 0.00 reconn/s: 0.00 [ 101s ] thds: 320 tps: 270.71 qps: 4334.41 (r/w/o: 3792.58/0.00/541.83) lat (ms,95%): 1678.14 err/s: 0.00 reconn/s: 0.00 [ 111s ] thds: 320 tps: 256.68 qps: 4100.25 (r/w/o: 3587.18/0.00/513.07) lat (ms,95%): 1771.29 err/s: 0.00 reconn/s: 0.00 [ 121s ] thds: 320 tps: 261.12 qps: 4087.48 (r/w/o: 3578.23/0.00/509.25) lat (ms,95%): 1708.63 err/s: 0.00 reconn/s: 0.00 SQL statistics: queries performed: read: 438242 write: 0 other: 62606 total: 500848 transactions: 31303 (258.37 per sec.) queries: 500848 (4133.87 per sec.) ignored errors: 0 (0.00 per sec.) reconnects: 0 (0.00 per sec.)
