标签:thread 列表 sudo 测试 x86 关闭 host lua mem
SysBench是一个模块化的、跨平台、多线程基准测试工具,主要用于评估测试各种不同系统参数下的数据库负载情况。它主要包括以下几种方式的测试:
源码下载:https://github.com/akopytov/sysbench/releases/tag/1.0.20
rpm包下载:https://packagecloud.io/akopytov/sysbench/packages/el/7/sysbench-1.0.20-1.el7.x86_64.rpm:
yum -y install make automake libtool pkgconfig libaio-devel mariadb-devel openssl-devel
解压源码:
tar -xf sysbench-1.0.20.tar.gz -C /opt/software/
进入目录:
cd /opt/software/sysbench-1.0.20/
编译安装:
./autogen.sh
./configure
make -j
make install
检查安装:
sysbench --version
sysbench: error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory
先查找一下本地有没有这个文件:
find / -name libmysqlclient.so.20
我们发现mysql软件目录下有这个文件,我们先建立软连接到/usr/lib
ln -s /opt/mysql/lib/libmysqlclient.so.20 /usr/lib
如果没有生效,接着在/etc/ld.so.cnf
中加入/usr/lib
这一行
echo ‘/usr/lib‘ >> /etc/ld.so.conf
执行ldconfig
更新下配置即可生效
ldconfig
curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash

Compiled-in tests:
fileio - File I/O test

See ‘sysbench <testname> help‘ for a list of options for each test.
Usage:
sysbench [options]... [test_lua] [lua_options] [command]
Commands implemented by most tests: prepare run cleanup help
例如,要查看oltp_common.lua的用法,可以:
sysbench /usr/share/sysbench/oltp_common.lua help
如果找不到脚本,可以find查找一下在哪个位置
prepare
run
cleanup
和help
首先创建sysbench所需数据库sbtest(这是sysbench默认使用的库名,必须创建测试库)。
然后,准备测试所用的表,这些测试表放在测试库sbtest中。这里使用的lua脚本为/usr/share/sysbench/oltp_common.lua
。
sysbench --mysql-host=192.168.80.54 --mysql-port=21021 --mysql-user=root --mysql-password=123 /usr/share/sysbench/oltp_common.lua --tables=10 --table_size=100000 prepare
其中--tables=10表示创建10个测试表,--table_size=100000表示每个表中插入10W行数据,prepare表示这是准备数的过程。
mysql> show tables from sbtest;
+------------------+
| Tables_in_sbtest |
+------------------+
| sbtest1 |
| sbtest10 |
| sbtest2 |
| sbtest3 |
| sbtest4 |
| sbtest5 |
| sbtest6 |
| sbtest7 |
| sbtest8 |
| sbtest9 |
+------------------+
mysql> select count(*) from sbtest.sbtest1;
+----------+
| count(*) |
+----------+
| 100000 |
+----------+
如果想要清除这10个表,可使用cleanup命令。
sysbench --mysql-host=192.168.80.54 --mysql-port=21021 --mysql-user=root --mysql-password=123 /usr/share/sysbench/oltp_common.lua --tables=10 --table_size=100000 cleanup
稍微修改下之前准备数据的语句,就可以拿来测试了。
需要注意的是,之前使用的lua脚本为oltp_common.lua
,它是一个通用脚本,是被其它lua脚本调用的,它不能直接拿来测试。
所以,我这里用oltp_read_write.lua
脚本来做读、写测试。还有很多其它类型的测试,比如只读测试、只写测试、删除测试、大批量插入测试等等。可找到对应的lua脚本进行调用即可。
sysbench --threads=4 --time=20 --report-interval=5 --mysql-host=192.168.80.54 --mysql-port=6033 --mysql-user=root --mysql-password=123 /usr/share/sysbench/oltp_read_write.lua --tables=10 --table_size=100000 run
以下是测试返回的结果:

sysbench内置了几个测试指标。
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
可直接help输出测试方法。例如,fileio测试。
[root@mysql8 tests]# sysbench fileio help
sysbench 1.0.20 (using bundled LuaJIT 2.1.0-beta2)
fileio options:
--file-num=N number of files to create [128]
--file-block-size=N block size to use in all IO operations [16384]
--file-total-size=SIZE total size of files to create [2G]
--file-test-mode=STRING test mode {seqwr, seqrewr, seqrd, rndrd, rndwr, rndrw}
--file-io-mode=STRING file operations mode {sync,async,mmap} [sync]
--file-async-backlog=N number of asynchronous operatons to queue per thread [128]
--file-extra-flags=[LIST,...] list of additional flags to use to open files {sync,dsync,direct} []
--file-fsync-freq=N do fsync() after this number of requests (0 - don‘t use fsync()) [100]
--file-fsync-all[=on|off] do fsync() after each write operation [off]
--file-fsync-end[=on|off] do fsync() at the end of test [on]
--file-fsync-mode=STRING which method to use for synchronization {fsync, fdatasync} [fsync]
--file-merged-requests=N merge at most this number of IO requests if possible (0 - don‘t merge) [0]
--file-rw-ratio=N reads/writes ratio for combined test [1.5]
例如,创建5个文件,总共1G,每个文件大概200M。
sysbench fileio --file-num=5 --file-total-size=1G prepare
[root@mysql8 ~]# ll -h test*
-rw------- 1 root root 205M 10月 17 18:41 test_file.0
-rw------- 1 root root 205M 10月 17 18:41 test_file.1
-rw------- 1 root root 205M 10月 17 18:41 test_file.2
-rw------- 1 root root 205M 10月 17 18:41 test_file.3
-rw------- 1 root root 205M 10月 17 18:41 test_file.4
然后,运行测试。
sysbench --events=5000 --threads=16 fileio --file-num=5 --file-total-size=1G --file-test-mode=rndrw --file-fsync-freq=0 --file-block-size=16384 run
