sysbench的安装详解

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.

　　到目前为止sysbench的安装就算是完成了！

五、sysbench的帮助内容如下：

 Usage:
   sysbench [options]... [testname] [command]

 Commands implemented by most tests: prepare run cleanup help

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
-rwxr-xr-x.  root root   10月  : bulk_insert.lua
-rw-r--r--.  root root  10月  : oltp_common.lua
-rwxr-xr-x.  root root   10月  : oltp_delete.lua
-rwxr-xr-x.  root root   10月  : oltp_insert.lua
-rwxr-xr-x.  root root   10月  : oltp_point_select.lua
-rwxr-xr-x.  root root   10月  : oltp_read_only.lua
-rwxr-xr-x.  root root   10月  : oltp_read_write.lua
-rwxr-xr-x.  root root   10月  : oltp_update_index.lua
-rwxr-xr-x.  root root   10月  : oltp_update_non_index.lua
-rwxr-xr-x.  root root   10月  : oltp_write_only.lua
-rwxr-xr-x.  root root   10月  : select_random_points.lua
-rwxr-xr-x.  root root   10月  : select_random_ranges.lua
drwxr-xr-x.  root root     10月  : 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= --mysql-user=sbtest \
    --mysql-password= --mysql-db=tempdb oltp_insert prepare

　　2、第二步 run

sysbench --mysql-host=localhost --mysql-port= --mysql-user=sbtest     --mysql-password= --mysql-db=tempdb oltp_insert run
sysbench 1.1. (using bundled LuaJIT 2.1.-beta3)

Running the test with following options:
Number of threads:
Initializing random number generator from current time

Initializing worker threads...

Threads started!

SQL statistics:
    queries performed:
        read:
        write:
        other:
        total:
    transactions:                          (2254.37 per sec.)
    queries:                               (2254.37 per sec.)
    ignored errors:                            (0.00 per sec.)
    reconnects:                                (0.00 per sec.)

Throughput:
    events/s (eps):                      2254.3691
    time elapsed:                        .0006s
    total number of events:              

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= --mysql-user=sbtest     --mysql-password= --mysql-db=tempdb oltp_insert cleanup
sysbench 1.1. (using bundled LuaJIT 2.1.-beta3)

Dropping table 'sbtest1'...
