6 MySQL数据库测试 select
首先需要创建默认的test数据库,或者使用–mysql-db指定一个已经存在的数据库生成测试数据，引擎为innodb,表大小为30000000条记录
6.1 准备数据
两种oltp的方式对比：
--oltp-test-mode=STRING test type to use {simple,complex,nontrx,sp} [complex]
--oltp-nontrx-mode=STRING mode for non-transactional test {select, update_key, update_nokey, insert, delete} [select]
执行命令：
time sysbench --test=oltp --mysql-table-engine=innodb --mysql-user=root --db-driver=mysql --mysql-db=test --oltp-table-size=300000000 --oltp-table-name=t1 --oltp-nontrx-mode=insert --mysql-socket=/opt/mysql/product/mysql/mysql3306.sock prepare
执行过程报错如下：
FATAL: no database driver specified
FATAL: failed to initialize database driver!
原因是test库没有建立，去create database

7.4 总结
oltp方式选择：
–oltp-nontrx-mode=STRING mode for non-transactional test {select, update_key, update_nokey, insert, delete} [select]
–max-requests=N limit for total number of requests [10000]
如果这里不指定–max-requests，默认为10000，就是执行1W次操作就结束了，如果要做压力测试的话，就需要手动设置此值。
–num-threads=N number of threads to use [1] (clients to access mysql db)
这里指的是有多少个mysql clents来访问mysql服务器，用show full processlist就可以看到大概的记录数。
7.5 接下来重新压力测试，设置2000W request测试。

nohup time sysbench --test=oltp --oltp-test-mode=nontrx --mysql-table-engine=innodb --mysql-host=xxxx.xx --mysql-user=xxxxx--mysql-password=hRhsYzbm --db-driver=mysql --num-threads=500 --max-requests=20000000 --oltp-nontrx-mode=select --mysql-db=test --oltp-table-size=20000000 --oltp-table-name=t1 --mysql-socket=/opt/mysql/product/mysql/mysql3306.sock prepare > 6.log &
执行过程：
sysbench 0.4.12: multi-threaded system evaluation benchmark

7.8.2 混合读写测试 远程读写
执行命令：
nohup time sysbench --test=oltp --oltp-test-mode=complex --mysql-table-engine=innodb --mysql-host=xxxxxx.xx.com --mysql-user=chunman --mysql-password=hRhsYzbm --db-driver=mysql --mysql-db=test --oltp-table-name=t1 --num-threads=500 --max-requests=20000000 --oltp-nontrx-mode=select --oltp-table-size=20000000 --mysql-socket=/opt/mysql/product/mysql/mysql3306.sock run >5.log &
执行显示过程：
ALERT: Error: failed to determine table 't1' type!
ALERT: MySQL error:
FATAL: failed to get database capabilities!

报这个错误，是因为数据没有，7.8.1没有执行，需要重新录入测试数据。
后续准备做mysql的性能监控工具。
