MySql性能测试工具-sysbench

转自：MySql性能测试工具-sysbench — 没那么简单的博客

虽然mysql默认的有mysqlslap这个性能测试工具，但和sysbench比较来说，还逊色不少。

shell> wget /akopytov/sysbench/archive/1.0.zip -O "sysbench-1.0.zip"shell> unzip sysbench-1.0.zipshell> cd sysbench-1.0

安装依赖库

shell> yum install automake libtool -y

开始安装

shell> ./autogen.shshell> ./configure#ERROR: cannot find MySQL libraries. If you want to compile with MySQL support 没找到mysql库 需要用参数指定下 --with-mysql-includes和--with-mysql-libsshell> ./configure --with-mysql-includes=/alidata/server/mysql5.7/include/ --with-mysql-libs=/alidata/server/mysql5.7/lib/shell> make

执行下命令:

shell> sysbench --help#sysbench: error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory#问题原因：sysbench无法找到mysql的库文件，可能是环境变量LD_LIBRARY_PATH没有设置，设置后即可解决该问题：shell> export LD_LIBRARY_PATH=/alidata/server/mysql5.7/lib/libshell> sysbench --versionsysbench 1.0

创建测试数据库sbtest

shell> mysqladmin create sbtest -uroot -pEnter password:

测试准备: 20个并发连接，20张表 每个表填充10W条数据 最大请求时间120s

#-test=tests/db/oltp.lua 表示调用 tests/db/oltp.lua 脚本进行 oltp 模式测试#--oltp_tables_count=10 表示会生成 10 个测试表#--oltp-table-size=100000 表示每个测试表填充数据量为 100000 #--rand-init=on 表示每个测试表都是用随机数据来填充的#-num-threads=8 表示发起 8个并发连接#--oltp-read-only=off 表示不要进行只读测试，也就是会采用读写混合模式测试#--report-interval=10 表示每10秒输出一次测试进度报告#--rand-type=uniform 表示随机类型为固定模式，其他几个可选随机模式：uniform(固定),gaussian(高斯),special(特定的),pareto(帕累托)#--max-time=120 表示最大执行时长为 120秒#--max-requests=0 表示总请求数为 0，因为上面已经定义了总执行时长，所以总请求数可以设定为 0；也可以只设定总请求数，不设定最大执行时长#--percentile=99 表示设定采样比例，默认是 95%，即丢弃1%的长请求，在剩余的99%里取最大值shell> sysbench --test=oltp --oltp_tables_count=10 --oltp-table-size=100000 --mysql-user=root --mysql-password=123456 --num-threads=20 --max-time=120 --max-requests=0 --oltp-test-mode=complex preparesysbench 1.0: multi-threaded system evaluation benchmarkCreating table 'sbtest1'...Inserting 100000 records into 'sbtest1'Creating secondary indexes on 'sbtest1'...Creating table 'sbtest2'...Inserting 100000 records into 'sbtest2'Creating secondary indexes on 'sbtest2'...Creating table 'sbtest3'...Inserting 100000 records into 'sbtest3'Creating secondary indexes on 'sbtest3'...Creating table 'sbtest4'...Inserting 100000 records into 'sbtest4'Creating secondary indexes on 'sbtest4'...Creating table 'sbtest5'...Inserting 100000 records into 'sbtest5'Creating secondary indexes on 'sbtest5'...Creating table 'sbtest6'...Inserting 100000 records into 'sbtest6'Creating secondary indexes on 'sbtest6'...Creating table 'sbtest7'...Inserting 100000 records into 'sbtest7'Creating secondary indexes on 'sbtest7'...Creating table 'sbtest8'...Inserting 100000 records into 'sbtest8'Creating secondary indexes on 'sbtest8'...Creating table 'sbtest9'...Inserting 100000 records into 'sbtest9'Creating secondary indexes on 'sbtest9'...Creating table 'sbtest10'...Inserting 100000 records into 'sbtest10'Creating secondary indexes on 'sbtest10'...

7.开始测试

shell> sysbench --test=oltp --oltp_tables_count=10 --oltp-table-size=100000 --mysql-user=root --mysql-password=123456 --num-threads=20 --max-time=120 --max-requests=0 --oltp-test-mode=complex run >> /tmp/log/sysbench_oltpx_1121.log#执行结束后查看测试报告shell> less /tmp/log/sysbench_oltpx_1121.logsysbench 1.0: multi-threaded system evaluation benchmark#报告内容如下:Running the test with following options:Number of threads: 20Initializing random number generator from current timeInitializing worker threads...Threads started!OLTP test statistics:queries performed:read: 935592 --读总数write: 267295 --写总数other: 133650 --其他操作(CURD之外的操作，例如COMMIT)total: 1336537 --全部总数transactions: 66822 (556.77 per sec.) --总事务数(每秒事务数)read/write requests: 1202887 (10022.55 per sec.) --读写总数(每秒读写次数)other operations:133650 (1113.58 per sec.) --其他操作总数(每秒其他操作次数)ignored errors: 6(0.05 per sec.) --总忽略错误总数(每秒忽略错误次数)reconnects:0(0.00 per sec.) --重连总数(每秒重连次数)General statistics: --常规统计total time:120.0180s --总耗时total number of events: 66822 --共发生多少事务数total time taken by event execution: 2399.7900s --所有事务耗时相加(不考虑并行因素)response time:min: 2.76ms --最小耗时avg: 35.91ms --平均耗时max: 1435.19ms --最长耗时approx. 95 percentile: 84.22ms --超过95%平均耗时Threads fairness: --并发统计events (avg/stddev): 3341.1000/37.54 --总处理事件数/标准偏差execution time (avg/stddev): 119.9895/0.02--总执行时间/标准偏差
