以下的文章主要介紹的是MySQL壓力測(cè)試工具，我們大家都知道MySQL數(shù)據(jù)庫(kù)在實(shí)際應(yīng)用中可以說(shuō)應(yīng)用率還是不算低的，采用MySQL數(shù)據(jù)庫(kù)也一般是中小企業(yè)，以下的文章就主要介紹的是MySQL數(shù)據(jù)庫(kù)的壓力測(cè)試工具。

MySQLslap是一個(gè)MySQL官方提供的壓力測(cè)試工具。以下是比較重要的參數(shù)：

–defaults-file，配置文件存放位置

–concurrency，并發(fā)數(shù)

–engines，引擎

–iterations，迭代的實(shí)驗(yàn)次數(shù)

–socket，socket文件位置

自動(dòng)測(cè)試：

–auto-generate-sql，自動(dòng)產(chǎn)生測(cè)試SQL

–auto-generate-sql-load-type，測(cè)試SQL的類型。類型有mixed，update，write，key，read。

–number-of-queries，執(zhí)行的SQL總數(shù)量

–number-int-cols，表內(nèi)int列的數(shù)量

–number-char-cols，表內(nèi)char列的數(shù)量

例如：

shell>MySQLslap –defaults-file=/u01/MySQL1/MySQL/my.cnf –concurrency=50,100 –iterations=1 –number-int-cols=4 –auto-generate-sql –auto-generate-sql-load-type=write –engine=myisam –number-of-queries=200 -S/tmp/MySQL1.sock

Benchmark

Running for engine myisam

Average number of seconds to run all queries: 0.016 seconds

Minimum number of seconds to run all queries: 0.016 seconds

Maximum number of seconds to run all queries: 0.016 seconds

Number of clients running queries: 50

Average number of queries per client: 4

Benchmark

Running for engine myisam

Average number of seconds to run all queries: 0.265 seconds

Minimum number of seconds to run all queries: 0.265 seconds

Maximum number of seconds to run all queries: 0.265 seconds

Number of clients running queries: 100

Average number of queries per client: 2

MySQL壓力測(cè)試工具中指定數(shù)據(jù)庫(kù)的測(cè)試：

–create-schema，指定數(shù)據(jù)庫(kù)名稱

–query，指定SQL語(yǔ)句，可以定位到某個(gè)包含SQL的文件

例如：

shell>MySQLslap –defaults-file=/u01/MySQL1/MySQL/my.cnf –concurrency=25,50 –iterations=1 –create-schema=test –query=/u01/test.sql -S/tmp/MySQL1.sock

Benchmark

Average number of seconds to run all queries: 0.018 seconds

Minimum number of seconds to run all queries: 0.018 seconds

Maximum number of seconds to run all queries: 0.018 seconds

Number of clients running queries: 25

Average number of queries per client: 1

Benchmark

Average number of seconds to run all queries: 0.011 seconds

Minimum number of seconds to run all queries: 0.011 seconds

Maximum number of seconds to run all queries: 0.011 seconds

Number of clients running queries: 50

Average number of queries per client: 1

以上的相關(guān)內(nèi)容就是對(duì)MySQL壓力測(cè)試工具的介紹，望你能有所收獲。
