前言

sysbench是一個(gè)開源的、模塊化的、跨平臺(tái)的多線程性能測試工具，可以用來進(jìn)行CPU、內(nèi)存、磁盤I/O、線程、數(shù)據(jù)庫的性能測試。sysbench是基于LuaJIT的可編寫腳本的多線程基準(zhǔn)測試工具。

sysbench附帶以下捆綁的基準(zhǔn)測試：

oltp_*.lua：類似OLTP的數(shù)據(jù)庫基準(zhǔn)測試的集合
fileio：文件系統(tǒng)級(jí)基準(zhǔn)
cpu：簡單的CPU基準(zhǔn)測試
memory：內(nèi)存訪問基準(zhǔn)
threads：基于線程的調(diào)度程序基準(zhǔn)
mutex：POSIX互斥基準(zhǔn)測試

特征

提供有關(guān)速率和延遲的大量統(tǒng)計(jì)信息，包括延遲百分位數(shù)和直方圖；
即使有數(shù)千個(gè)并發(fā)線程，開銷也很低。sysbench每秒能夠生成和跟蹤數(shù)億個(gè)事件。
通過在用戶提供的Lua腳本中實(shí)現(xiàn)預(yù)定義的掛鉤，可以輕松創(chuàng)建新的基準(zhǔn)測試；
可以也可以作為一個(gè)通用的Lua解釋，只需更換#!/usr/bin/lua用#!/usr/bin/sysbench在你的腳本。

安裝

安裝以Centos為例，其他版本或者mac請(qǐng)參考sysbench說明

1.下載安轉(zhuǎn)

wget https://github.com/akopytov/sysbench/archive/1.0.zip -O "sysbench-1.0.zip"
unzip sysbench-1.0.zip
cd sysbench-1.0
//安裝依賴
yum install -y automake libtool

2.編譯安裝

./autogen.sh
./configure
export LD_LIBRARY_PATH=/usr/include/mysql
make
make install

3.監(jiān)測是否安裝成功

[root@guanbin-k8s-master ~]# sysbench --version
sysbench 1.0.19

測試

1. cpu測試

cpu測試主要是進(jìn)行素?cái)?shù)的加法運(yùn)算，我們的例子中，指定了最大的質(zhì)數(shù)發(fā)生器數(shù)量為 20000

[root@guanbin-k8s-master ~]# sysbench --test=cpu --cpu-max-prime=20000 run

執(zhí)行時(shí)間大約為10秒（這個(gè)測試最好是兩臺(tái)機(jī)器進(jìn)行對(duì)比測試，才能發(fā)現(xiàn)那個(gè)機(jī)器有問題）

2.對(duì)內(nèi)存（memory）進(jìn)行測試

測試是在內(nèi)存中傳輸 10G 的數(shù)據(jù)量，每個(gè) block 大小為 8K

totaltime為1.8045s

3.對(duì)disk 的IO測試

新建一個(gè)臨時(shí)目錄，并確保磁盤剩余空間足夠（--file-total-size不要超過剩余容量）

測試場景：16個(gè)線程，創(chuàng)建128個(gè)文件，總共占用磁盤空間10GB，測試磁盤讀寫效率

運(yùn)行結(jié)束后要?jiǎng)h除臨時(shí)測試文件： rm -rf test_file.*

4.測試mysql性能

測試時(shí)使用的腳本為lua腳本，可以使用sysbench自帶腳本，也可以自己開發(fā)。對(duì)于大多數(shù)應(yīng)用，使用sysbench自帶的腳本就足夠了。不同版本的sysbench中，lua腳本的位置可能不同，可以自己在sysbench路徑下使用find命令搜索oltp.lua。

P.S.：大多數(shù)數(shù)據(jù)服務(wù)都是oltp類型的，如果你不了解什么是oltp，那么大概率你的數(shù)據(jù)服務(wù)就是oltp類型的。MySQL OLTP（On-Line Transaction Processing聯(lián)機(jī)事務(wù)處理過程）；

（1）盡量不要在MySQL服務(wù)器運(yùn)行的機(jī)器上進(jìn)行測試，一方面可能無法體現(xiàn)網(wǎng)絡(luò)（哪怕是局域網(wǎng)）的影響，另一方面，sysbench的運(yùn)行（尤其是設(shè)置的并發(fā)數(shù)較高時(shí)）會(huì)影響MySQL服務(wù)器的表現(xiàn)。
（2）可以逐步增加客戶端的并發(fā)連接數(shù)（--thread參數(shù)），觀察在連接數(shù)不同情況下，MySQL服務(wù)器的表現(xiàn)；如分別設(shè)置為10,20,50,100等。
（3）一般執(zhí)行模式選擇complex即可，如果需要特別測試服務(wù)器只讀性能，或不使用事務(wù)時(shí)的性能，可以選擇simple模式或nontrx模式。
（4）如果連續(xù)進(jìn)行多次測試，注意確保之前測試的數(shù)據(jù)已經(jīng)被清理干凈。

下面是sysbench使用的一個(gè)例子：

注意：先準(zhǔn)備數(shù)據(jù)庫

mysql> create database sbtest;

其中，執(zhí)行模式為complex，使用了10個(gè)表，每個(gè)表有10萬條數(shù)據(jù)，客戶端的并發(fā)線程數(shù)為10，執(zhí)行時(shí)間為120秒，每10秒生成一次報(bào)告。

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host={yourhostip} --mysql-port=3306 --mysql-user={username} --mysql-password={password} --oltp-test-mode=complex --mysql-table-engine=innodb --oltp-tables-count=10 --oltp-table-size=100000 --threads=10 --time=120 --report-interval=10 prepare

其中的hostip、username、password請(qǐng)自行切換為自己真實(shí)的環(huán)境數(shù)據(jù)

查看執(zhí)行結(jié)果

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host={yourhostip} --mysql-port=3306 --mysql-user={username} --mysql-password={password} --oltp-test-mode=complex --oltp-tables-count=10 --oltp-table-size=100000 --threads=10 --time=120 --report-interval=10 run
