我将按照本指南使用 flexAsynch 对 MySQL 集群进行基准测试,详细信息如下:
mkdir /usr/local/mysqlc732/
cd /usr/local/src/mysql-cluster-gpl-7.3.2
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysqlc732/ -DWITH_NDB_TEST=ON
make
make install
在这一步之前一切正常:
# /usr/local/mysqlc732/bin/flexAsynch -t 1 -p 80 -l 2 -o 100 -c 100 -n
FLEXASYNCH - Starting normal mode
Perform benchmark of insert, update and delete transactions
1 number of concurrent threads
80 number of parallel operation per thread
100 transaction(s) per round
2 iterations
Load Factor is 80%
25 attributes per table
1 is the number of 32 bit words per attribute
Tables are with logging
Transactions are executed with hint provided
No force send is used, adaptive algorithm used
Key Errors are disallowed
Temporary Resource Errors are allowed
Insufficient Space Errors are disallowed
Node Recovery Errors are allowed
Overload Errors are allowed
Timeout Errors are allowed
Internal NDB Errors are allowed
User logic reported Errors are allowed
Application Errors are disallowed
Using table name TAB0
NDBT_ProgramExit: 1 - Failed
ndb_cluster.log:
警告 -- 未能在 127.0.0.1 为 API 分配 nodeid。返回错误:“未找到 mysqld(API) 的可用节点 ID。”
我也用-DWITH_DEBUG=1 -DWITH_NDB_DEBUG=1
. 如何flexAsynch
在调试模式下运行?
# /usr/local/mysqlc732/bin/flexAsynch -h
FLEXASYNCH
Perform benchmark of insert, update and delete transactions
Arguments:
-t Number of threads to start, default 1
-p Number of parallel transactions per thread, default 32
-o Number of transactions per loop, default 500
-l Number of loops to run, default 1, 0=infinite
-load_factor Number Load factor in index in percent (40 -> 99)
-a Number of attributes, default 25
-c Number of operations per transaction
-s Size of each attribute, default 1
(PK is always of size 1, independent of this value)
-simple Use simple read to read from database
-dirty Use dirty read to read from database
-write Use writeTuple in insert and update
-n Use standard table names
-no_table_create Don't create tables in db
-temp Create table(s) without logging
-no_hint Don't give hint on where to execute transaction coordinator
-adaptive Use adaptive send algorithm (default)
-force Force send when communicating
-non_adaptive Send at a 10 millisecond interval
-local 1 = each thread its own node, 2 = round robin on node per parallel trans 3 = random node per parallel trans
-ndbrecord Use NDB Record
-r Number of extra loops
-insert Only run inserts on standard table
-read Only run reads on standard table
-update Only run updates on standard table
-delete Only run deletes on standard table
-create_table Only run Create Table of standard table
-drop_table Only run Drop Table on standard table
-warmup_time Warmup Time before measurement starts
-execution_time Execution Time where measurement is done
-cooldown_time Cooldown time after measurement completed
-table Number of standard table, default 0
因为
flexAsynch
使用了异步 NDB API,所以我必须添加一个空闲槽config.ini
:然后重启管理节点和所有数据节点:
重新运行
flexAsynch
,现在它工作正常:
