初始化测试库环境（总共16个测试表，每个表 500000 条记录，填充随机生成的数据）：

# cd /software/sysbench

-- 在脚本里面把 # sysbenc cleanup and perpare 这一行下面两个语句去掉注释，或者自己执行

# sysbench $lua_dir/parallel_prepare.lua --mysql-user=$6 --mysql-password=$7 --mysql-port=$5 --mysql-host=$4 $SYSBENCH_PARAMETER  --num-threads=8 cleanup

# sysbench $lua_dir/parallel_prepare.lua --mysql-user=$6 --mysql-password=$7 --mysql-port=$5 --mysql-host=$4 $SYSBENCH_PARAMETER  --num-threads=8 prepare 

-- 自己执行

/usr/local/bin/sysbench /software/sysbench/tests/include/oltp_legacy/oltp.lua  --mysql-user=xxx --mysql-password=xxx --mysql-host=localhost  --mysql-socket=/r2/mysqldata/mysql.sock --mysql-port=3306 --mysql-table-engine=innodb --oltp-table-size=5000000 --oltp-tables-count=16 --oltp-test-mode=complex --rand-type=uniform --rand-init=on --report-interval=10  --max-time=1500  --num-threads=8   cleanup

/usr/local/bin/sysbench /software/sysbench/tests/include/oltp_legacy/oltp.lua  --mysql-user=xxx --mysql-password=xxx --mysql-host=localhost  --mysql-socket=/r2/mysqldata/mysql.sock --mysql-port=3306 --mysql-table-engine=innodb --oltp-table-size=5000000 --oltp-tables-count=16 --oltp-test-mode=complex --rand-type=uniform --rand-init=on --report-interval=10  --max-time=1500  --num-threads=8   prepare

关于这几个参数的解释：
- -- /software/sysbench/tests/include/oltp_legacy/oltp.lua 表示调用 oltp.lua 脚本进行 oltp 模式测试
- --oltp_tables_count=16 表示会生成 16 个测试表
- --oltp-table-size=5000000 表示每个测试表填充数据量为 5000000
- --rand-init=on 表示每个测试表都是用随机数据来填充的

如果在本机，也可以使用 –mysql-socket 指定 socket 文件来连接。

真实测试场景中，数据表建议不低于10个，单表数据量不低于500万行，当然了，要视服务器硬件配置而定。如果是配备了SSD或者PCIE SSD这种高IOPS设备的话，则建议单表数据量最少不低于1亿行。

二、进行OLTP测试

执行脚本测试，使用sh 脚本 test (测试名称) (测试类型) (mysql_host) (mysql_port) (mysql_user) (mysql_password)，如下：

[root@dbproxy01 software]# sh  mysql_oltp_sysbench.sh test deadlock_check_on read-write localhost 3306 root 'iforgot'

命令测试
- 启动了256个线程，16个测试表，每个表中灌入500W条数据，测试时间1个小时

sysbench /software/sysbench/tests/include/oltp_legacy/oltp.lua --mysql-host=localhost --mysql-port=3306 --mysql-user=root --mysql-password=yourpassword --oltp_tables_count=10 --oltp-table-size=5000000 --num-threads=256 --oltp-read-only=off --report-interval=10 --rand-type=uniform --max-time=3600 --max-requests=1000000 --percentile=99 run >> /tmp/sysbench_oltpX_256_20171026.log

选项说明：
- --num-threads=8 表示发起 8个并发连接
- --oltp-read-only=off 表示不要进行只读测试，也就是会采用读写混合模式测试
- --report-interval=10 表示每10秒输出一次测试进度报告
- --rand-type=uniform 表示随机类型为固定模式，其他几个可选随机模式：uniform(固定),gaussian(高斯),special(特定的),pareto(帕累托)
- --max-time=3600 表示最大执行时长为 3600秒
- --max-requests=0 表示总请求数为 0，因为上面已经定义了总执行时长，所以总请求数可以设定为 0；也可以只设定总请求数，不设定最大执行时长
- --percentile=99 表示设定采样比例，默认是 95%，即丢弃1%的长请求，在剩余的99%里取最大值;即模拟对16个表并发OLTP测试，每个表500万行记录，持续压测时间为 1小时。

真实测试场景中，建议持续压测时长不小于30分钟，否则测试数据可能不具参考意义。

竖轴为查询数，横轴为线程数

竖轴为事务数，横轴为线程数

竖轴为95%平均响应时间，横轴为线程数

四、关于测试后的结论：

innodb_deadlock_detect 开启都性能有5%左右的损耗,性能满是的情况下，尽量还是开启有助于优化

五、关于测试后的性能优化：

1、善后清理工作：

进mysql删除dbtest库

mysql> drop database dbtest;

可以运行./mysqltuner.pl程序，根据建议对数据库进行调优后，再使用sysbench对OLTP进行测试，看看TPS是不是会有所提高。

注意：sysbench的测试只是基准测试，并不能代表实际企业环境下的性能指标。

2、运行优化建议工具



# ./mysqltuner.pl

建议：

[plain] view plain copy

General recommendations:

    Run OPTIMIZE TABLE to defragment tables for better performance

    MySQL started within last 24 hours - recommendations may be inaccurate

    Reduce your overall MySQL memory footprint for system stability

    Enable the slow query log to troubleshoot bad queries

    Reduce or eliminate unclosed connections and network issues

Variables to adjust:

  *** MySQL's maximum memory usage is dangerously high ***

  *** Add RAM before increasing MySQL buffer variables ***

    query_cache_type (=0)

    innodb_buffer_pool_size (>= 1G) if possible.

    innodb_buffer_pool_instances(=8)

3、修改mysql参数

# vim /etc/my.cnf

[plain] view plain copy

innodb_buffer_pool_instances = 8

innodb_buffer_pool_size = 1024M 

每轮测试完成后，都重启mysqld实例，并且用下面的方法删除系统cache，释放swap（如果用到了swap的话），甚至可以重启整个OS。

# sync  -- 将脏数据刷新到磁盘

# sync  -- 将脏数据刷新到磁盘

# echo 3 > /proc/sys/vm/drop_caches  -- 清除OS Cache

# swapoff -a && swapon -a     -- 清除OS swap缓存

4、再次启动测试流程
