安装sysbench
OS readhat 6.4
mysql版本5.7
mysql安装目录
下载安装包 https://github.com/akopytov/sysbench
shell> wget https://github.com/akopytov/sysbench/archive/1.0.zip -O “sysbench-1.0.zip”
2. 安装依赖包
# yum -y install make automake libtool pkgconfig libaio-devel vim-common
3、上传到linux系统中(/usr/local/)，并且解压，进入/usr/local/执行：
p unzip sysbench-0.5.zip -d /usr/local
4、创建sysbench安装目录文件夹：
5、进入/usr/local/sysbench-master/执行：./autogen.sh
# cd /usr/local/sysbench-0.5
# ./autogen.sh
6.
#./configure –prefix=/usr/local/sysbench-0.5 –with-mysql-includes=/usr/local/mysql/include –with-mysql-libs=/usr/local/mysql/lib/;
7.
# make
8.
# make install
9.查看版本
[root@msyqlzhu sysbench-0.5]# /usr/local/sysbench-0.5/bin/sysbench version
sysbench 0.5
如果出现：(sysbench: error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory)报错，
则在(vim /etc/profile 中加入:export LD_LIBRARY_PATH=/usr/local/mysql/lib/)
常用参数:
#-test=tests/db/oltp.lua 表示调用 tests/db/oltp.lua 脚本进行 oltp 模式测试
#–oltp_tables_count=10 表示会生成 10 个测试表
#–oltp-table-size=100000 表示每个测试表填充数据量为 100000
#–rand-init=on 表示每个测试表都是用随机数据来填充的
#-num-threads=8 表示发起 8个并发连接
#–oltp-read-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=120 表示最大执行时长为 120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
测试文件IO

3.内存测试
[root@msyqlzhu ~]# /usr/local/sysbench-0.5/bin/sysbench –test=memory –memory-block-size=8K –memory-total-size=1G –num-threads=16 run
4. 文件IO基准测试
共1G
[root@msyqlzhu ~]# /usr/local/sysbench-0.5/bin/sysbench –test=fileio –file-total-size=1G prepare
1073741824 bytes written in 8.15 seconds (125.60 MB/sec).
测试文件IO 4个文件共4G
[root@msyqlzhu ~]# /usr/local/sysbench-0.5/bin/sysbench –test=fileio –file-num=4 –file-total-size=4G prepare
4261412864 bytes written in 6.52 seconds (623.68 MB/sec).
测试文件IO 4个文件共4G.块大小为16K
[root@msyqlzhu ~]# /usr/local/sysbench-0.5/bin/sysbench –test=fileio –file-num=4 –file-block-size=16384 –file-total-size=4G prepare
这个命令会在当前工作目录下创建测试文件，后续的运行(run)阶段将通过读写这些文件进行测试。 第二步就是运行(run)阶段，针对不同的IO 类型有不同的测试选项：
seqwr 顺序写入
seqrewr 顺序重写
seqrd 顺序读取
rndrd 随机读取
rndwr 随机写入
rndrw 混合随机读/写
下面的命令运行文件I/O混合随机读/写基准测试：
混合随机读/写
/usr/local/sysbench-0.5/bin/sysbench –test=fileio –file-total-size=4G –file-test-mode=rndrw –init-rng=on –max-time=300 –max-requests=0 run
清除测试的文件
/usr/local/sysbench-0.5/bin/sysbench –test=fileio –fil-total-size=30G cleanup
测试oltp
1.找到select.lua脚本路径
[root@msyqlzhu t]# find / -name oltp.lua
/usr/local/sysbench-0.5/sysbench/tests/db/oltp.lua
2.创建测试的时候默认用sbtest库
> create database sbtest;
