sysbench是一个压力测试工具、可以用它来测试cpu、mem、disk、thread、mysql、postgr、oracle；然而作为一个mysql dba 我当然是用它来压测mysql啦！
一、从哪里可以下载到sysbench：
sysbench的源码可以在github上面下载的到，sysbench的主页
https://github.com/akopytov/sysbench
二、sysbench的一些安装依赖：
yum -y install make automake libtool pkgconfig libaio-devel vim-common
在我的机器上已经安装上了mysql相关的所有包，如果你机器上还没有安装过这些，那你还要安装上mysql的开发包，由于系统自带mariadb
这个mysql分支，所以在安装mysql-devel时应该是安装mariadb-devel
三、安装sysbench：
1 进入到sysbench源码目录
/home/jianglexing/Desktop/sysbench-master
2 执行autogen.sh用它来生成configure这个文件
./autogen.sh
3 执行configure && make && make install 来完成sysbench的安装
./configure --prefix=/usr/local/sysbench/ --with-mysql --with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib make make install
我这里之所以要这样写是因为我的mysql安装在/usr/local/；而不是默认的rpm的安装位置
四、测试是否安装成功：
[root@workstudio bin]# /usr/local/sysbench/bin/sysbench --version sysbench 1.1.0
到目前为止sysbench的安装就算是完成了！
五、sysbench的帮助内容如下：

六、sysbench对数据库进行压力测试的过程：
1 prepare 阶段 这个阶段是用来做准备的、比较说建立好测试用的表、并向表中填充数据。
2 run 阶段 这个阶段是才是去跑压力测试的SQL
3 cleanup 阶段 这个阶段是去清除数据的、也就是prepare阶段初始化好的表要都drop掉
七、sysbench 中的测试类型大致可以分成内置的，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 自身内涵了一些测试脚本放在了安装目录下的：
[jianglexing@cstudio sysbench]$ ll share/sysbench 总用量 60 -rwxr-xr-x. 1 root root 1452 10月 17 15:18 bulk_insert.lua -rw-r--r--. 1 root root 13918 10月 17 15:18 oltp_common.lua -rwxr-xr-x. 1 root root 1290 10月 17 15:18 oltp_delete.lua -rwxr-xr-x. 1 root root 2415 10月 17 15:18 oltp_insert.lua -rwxr-xr-x. 1 root root 1265 10月 17 15:18 oltp_point_select.lua -rwxr-xr-x. 1 root root 1649 10月 17 15:18 oltp_read_only.lua -rwxr-xr-x. 1 root root 1824 10月 17 15:18 oltp_read_write.lua -rwxr-xr-x. 1 root root 1118 10月 17 15:18 oltp_update_index.lua -rwxr-xr-x. 1 root root 1127 10月 17 15:18 oltp_update_non_index.lua -rwxr-xr-x. 1 root root 1440 10月 17 15:18 oltp_write_only.lua -rwxr-xr-x. 1 root root 1919 10月 17 15:18 select_random_points.lua -rwxr-xr-x. 1 root root 2118 10月 17 15:18 select_random_ranges.lua drwxr-xr-x. 4 root root 46 10月 17 15:18 tests
八、通过sysbench自带的lua脚本对mysql进行测试：
1、第一步 prepare
sysbench --mysql-host=localhost --mysql-port=3306 --mysql-user=sbtest --mysql-password=123456 --mysql-db=tempdb oltp_insert prepare
2、第二步 run
sysbench --mysql-host=localhost --mysql-port=3306 --mysql-user=sbtest --mysql-password=123456 --mysql-db=tempdb oltp_insert run sysbench 1.1.0 (using bundled LuaJIT 2.1.0-beta3) Running the test with following options: Number of threads: 1 Initializing random number generator from current time Initializing worker threads... Threads started! SQL statistics: queries performed: read: 0 write: 22545 other: 0 total: 22545 transactions: 22545 (2254.37 per sec.) queries: 22545 (2254.37 per sec.) ignored errors: 0 (0.00 per sec.) reconnects: 0 (0.00 per sec.) Throughput: events/s (eps): 2254.3691 time elapsed: 10.0006s total number of events: 22545 Latency (ms): min: 0.31 avg: 0.44 max: 10.47 95th percentile: 0.67 sum: 9918.59 Threads fairness: events (avg/stddev): 22545.0000/0.00 execution time (avg/stddev): 9.9186/0.00
3、第三步 cleanup
sysbench --mysql-host=localhost --mysql-port=3306 --mysql-user=sbtest --mysql-password=123456 --mysql-db=tempdb oltp_insert cleanup sysbench 1.1.0 (using bundled LuaJIT 2.1.0-beta3) Dropping table 'sbtest1'...
