(轉)用mysql自帶工具mysqlslap對數據庫進行壓力測試
http://aolens.blog.51cto.com/7021142/1901557-------用mysql自帶工具mysqlslap對數據庫進行壓力測試
mysqlslap是mysql自帶的工具，不需要單獨安裝：
參數：
-concurrency 代表並發數量，多個可以用逗號隔開，concurrency=10,50,100, 並發連接線程數分別是10、50、100個並發。
--engines 代表要測試的引擎，可以有多個，用分隔符隔開。
--iterations 代表要運行這些測試多少次。
--auto-generate-sql 代表用系統自己生成的SQL腳本來測試。
--auto-generate-sql-load-type 代表要測試的是讀還是寫還是兩者混合的（read,write,update,mixed）
--number-of-queries 代表總共要運行多少次查詢。每個客戶運行的查詢數量可以用查詢總數/並發數來計算。
--debug-info 代表要額外輸出CPU以及內存的相關信息。
--number-int-cols ：創建測試表的 int 型字段數量
--auto-generate-sql-add-autoincrement : 代表對生成的表自動添加auto_increment列，從5.1.18版本開始
--number-char-cols 創建測試表的 char 型字段數量。
--create-schema 測試的schema，MySQL中schema也就是database。
--query 使用自定義腳本執行測試，例如可以調用自定義的一個存儲過程或者sql語句來執行測試。
--only-print 如果只想打印看看SQL語句是什麽，可以用這個選項。
1，簡單用法
| 1 2 3 4 5 6 7 8 9 10 11 12 13 |
[root@Linux_Aolens_01 /home/aolens]# mysqlslap --user=root --password=password --auto-generate-sql
Benchmark
Average number of seconds to run all queries: 0.002 seconds
Minimum number of seconds to run all queries: 0.002 seconds
Maximum number of seconds to run all queries: 0.002 seconds
Number of clients running queries: 1
Average number of queries per client: 0
|
結果中各項含義：
-
Average number of ... 運行所有語句的平均秒數
-
Minimum number of ... 運行所有語句的最小秒數
-
Maximum number of ... 運行所有語句的最大秒數
-
Number of clients ... 客戶端數量
-
Average number of queries per client 每個客戶端運行查詢的平均數
2，添加並發
| 1 2 3 4 5 6 7 |
[root@Linux_Aolens_01 /home/aolens]# mysqlslap --user=root --password=password --auto-generate-sql --concurrency=100 --number-of-queries=1000
Benchmark
Average number of seconds to run all queries: 0.316 seconds
Minimum number of seconds to run all queries: 0.316 seconds
Maximum number of seconds to run all queries: 0.316 seconds
Number of clients running queries: 100
Average number of queries per client: 10
|
3，使用自己測試庫和測試語句
| 1 2 3 4 5 6 7 |
[root@Linux_Aolens_01 /home/aolens]# mysqlslap --user=root --password=password --concurrency=10 --number-of-queries=100 --create-schema=wordpress --query="SELECT * FROM wordpress.wp_posts;"
Benchmark
Average number of seconds to run all queries: 4.255 seconds
Minimum number of seconds to run all queries: 4.255 seconds
Maximum number of seconds to run all queries: 4.255 seconds
Number of clients running queries: 10
Average number of queries per client: 10
|
4，結合實際，對網站首頁所請求的數據庫連接做壓力測試
數據庫Mariadb 10.0.14
首先給數據庫安裝審計插件，並啟用
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
MariaDB [(none)]> show variables like ‘%audit%‘
-> ;
+-------------------------------+-----------------------+
| Variable_name | Value |
+-------------------------------+-----------------------+
| server_audit_events | |
| server_audit_excl_users | |
| server_audit_file_path | server_audit.log |
| server_audit_file_rotate_now | OFF |
| server_audit_file_rotate_size | 1000000 |
| server_audit_file_rotations | 9 |
| server_audit_incl_users | |
| server_audit_logging | OFF |
| server_audit_mode | 0 |
| server_audit_output_type | file |
| server_audit_syslog_facility | LOG_USER |
| server_audit_syslog_ident | mysql-server_auditing |
| server_audit_syslog_info | |
| server_audit_syslog_priority | LOG_INFO |
+-------------------------------+-----------------------+
14 rows in set (0.00 sec)
|
發現已經安裝了，沒有安裝的MariaDB [(none)]> INSTALL PLUGIN server_audit SONAME ‘server_audit.so‘;
命令行啟動審計功能：
命令行啟用audit ，重啟後失效
| 1 2 3 4 5 6 7 8 |
MariaDB [(none)]> set global server_audit_file_rotate_size=1024*1024*1024;
Query OK, 0 rows affected (0.01 sec)
MariaDB [(none)]> set global server_audit_events=‘query,table‘;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> set global server_audit_file_rotate_now=on;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> set global server_audit_logging=‘ON‘;
Query OK, 0 rows affected (0.00 sec)
|
刷新一下首頁查看審計日誌裏都有哪些SQL操作，對這些SQL進行壓測：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
mysqlslap --user=root --password=password --concurrency=20 --number-of-queries=1000 --create-schema=wordpress --query=" \
SELECT option_name, option_value FROM wp_options WHERE autoload = ‘yes‘; \
SELECT option_value FROM wp_options WHERE option_name = ‘a3_lz_google_api_key‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘a3_lz_google_api_key_enable‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘_transient_timeout_a3_lz_google_api_key_status‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘_transient_a3_lz_google_api_key_status‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘wordpress_api_key‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘onp_license_clipboard-images‘ LIMIT 1; \
SELECT autoload FROM wp_options WHERE option_name = ‘onp_license_clipboard-images‘; \
SELECT option_value FROM wp_options WHERE option_name = ‘onp_version_check_clipboard-images‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘ossdl_https‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘uninstall_plugins‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘a3_lazy_load_just_installed‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘akismet_comment_nonce‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘preload_cache_counter‘ LIMIT 1; \
SELECT option_value FROM wp_options WHERE option_name = ‘rewrite_rules‘ LIMIT 1; \
......"
Benchmark
Average number of seconds to run all queries: 40.931 seconds
Minimum number of seconds to run all queries: 40.931 seconds
Maximum number of seconds to run all queries: 40.931 seconds
Number of clients running queries: 20
Average number of queries per client: 50
