sysbench内置测试脚本测试
此文介绍的是sysbench对mysql的测试，必备mysql环境和sysbench环境，缺少sysbench请移步：

sysbench 中的测试类型大致可以分成内置的测试，lua脚本自定义的测试：
1、内置：fileio 、cpu 、memory 、threads 、 mutex
2、lua脚本自定义型：
sysbench 自身内置了一些测试脚本放在了安装目录下，本文重点介绍脚本测试：
我的linux查看sysbench测试脚本如下：
[root@localhost sysbench]# pwd -P
/usr/local/sysbench/share/sysbench
[root@localhost sysbench]# ll
total 60

drwxr-xr-x 4 root root 49 Jul 27 10:39 testslua脚本测试步骤：
一、建立测试数据库(这部分属于mysql简单操作)：
在此先说明一下，我的mysql配置：用户名root，密码root，并且已经开启了服务。
建立空的测试数据库，用于测试：
mysql -uroot -proot
mysql> create database sysbenchtest;
# 连接数据库
# 创建测试空库 sysbenchtest 显示 Query OK, 1 row affected 表示成功了。
查看数据库
mysql> show databases;
# 创建成功！
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sakila |
| sysbenchtest |
好了，记得退出数据库；
mysql> exit;
二、sysbench连接数据库和测试：
lua脚本目录:/usr/local/sysbench/share/sysbench (我的sysbench安装位置是/usr/local/sysbench)
cd /usr/local/sysbench/share/sysbench# 进入脚本目录
开始测试三部曲：prepare run cleanup (准备工作 测试开始 清除测试数据)
step1.prepare:
sysbench --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-user=root --mysql-password=root --mysql-db=sysbenchtest oltp_insert prepare
step2.run:
sysbench --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-user=root --mysql-password=root --mysql-db=sysbenchtest oltp_insert run# 测试已经开始，数据库正在压力写入，请耐心等待几秒钟... 测试结束，测试数据如下:
Initializing worker threads...
Threads started!
SQL statistics:
queries performed:
read: 0

other: 0
total: 8467
transactions: 8467 (846.42 per sec.)
queries: 8467 (846.42 per sec.)
ignored errors: 0 (0.00 per sec.)

General statistics:
total time: 10.0004s
total number of events: 8467
Latency (ms):
min: 0.52
avg: 1.18
max: 40.81
95th percentile: 2.26
sum: 9957.20
Threads fairness:
events (avg/stddev): 8467.0000/0.00
execution time (avg/stddev): 9.9572/0.00
step3.cleanup:
sysbench --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-user=root --mysql-password=root --mysql-db=sysbenchtest oltp_insert cleanup# cleanup实质为删除测试表，注意别选错表了。
至此，测试完成！
sysbench --help
