mysqlslap是從MySQL的5.1.4版開始就開始官方提供的壓力測試工具。通過模擬多個并發(fā)客戶端并發(fā)訪問MySQL來執(zhí)行壓力測試，同時提供了較詳細的SQL執(zhí)行數(shù)據(jù)性能報告，并且能很好的對比多個存儲引擎（MyISAM，InnoDB等）在相同環(huán)境下的相同并發(fā)壓力下的性能差別。

參數(shù)參考表： --host=host_name, -h host_name  連接到的MySQL服務(wù)器的主機名（或IP地址），默認為本機localhost

--user=user_name, -u user_name 連接MySQL服務(wù)時用的用戶名

--password[=password], -p[password] 連接MySQL服務(wù)時用的密碼

--create-schema 代表自定義的測試庫名稱，測試的schema，MySQL中schema也就是database。

(沒指定使用哪個數(shù)據(jù)庫時，可能會遇到錯誤mysqlslap: Error when connecting to server: 1049 Unknown database 'mysqlslap')

--query=name,-q 使用自定義腳本執(zhí)行測試（可以是SQL字符串或腳本），例如可以調(diào)用自定義的一個存儲過程或者sql語句來執(zhí)行測試。

--create 創(chuàng)建表所需的SQL（可以是SQL字符串或腳本）

--concurrency=N, -c N 表示并發(fā)量，也就是模擬多少個客戶端同時執(zhí)行query?？芍付ǘ鄠€值，以逗號或者--delimiter參數(shù)指定的值做為分隔符。例如：--concurrency=100,200,500（分別執(zhí)行100、200、500個并發(fā)）。

--iterations=N, -i N 測試執(zhí)行的迭代次數(shù)，代表要在不同的并發(fā)環(huán)境中，各自運行測試多少次；多次運行以便讓結(jié)果更加準確。

--number-of-queries=N 總的測試查詢次數(shù)(并發(fā)客戶數(shù)×每客戶查詢次數(shù))

--engine=engine_name, -e engine_name 代表要測試的引擎，可以有多個，用分隔符隔開。例如：--engine=myisam,innodb,memory。

--auto-generate-sql, -a 自動生成測試表和數(shù)據(jù)，表示用mysqlslap工具自己生成的SQL腳本來測試并發(fā)壓力。

--auto-generate-sql-load-type=type 測試語句的類型。代表要測試的環(huán)境是讀操作還是寫操作還是兩者混合的。取值包括：read (scan tables), write (insert into tables), key (read primary keys), update (update primary keys), or mixed (half inserts, half scanning selects). 默認值是：mixed.

--auto-generate-sql-add-auto-increment 代表對生成的表自動添加auto_increment列，從5.1.18版本開始支持。

--number-char-cols=N, -x N 自動生成的測試表中包含多少個字符類型的列，默認1

--number-int-cols=N, -y N 自動生成的測試表中包含多少個數(shù)字類型的列，默認1

--commint=N 多少條DML后提交一次。

--compress, -C 如果服務(wù)器和客戶端支持都壓縮，則壓縮信息傳遞。

--only-print 只打印測試語句而不實際執(zhí)行。

--detach=N 執(zhí)行N條語句后斷開重連。

--debug-info, -T 打印內(nèi)存和CPU的相關(guān)信息。

mysqlslap的運行有如下3個步驟：
1. 創(chuàng)建schema、table、test data 等（在MySQL中，schema就是database）；
2. 運行負載測試，可以使用多個并發(fā)客戶端連接；
3. 測試環(huán)境清理（刪除創(chuàng)建的數(shù)據(jù)、表等）。
