sysbench安装及性能测试
现在的压力测试工具各种各样，只要上手好几款功能强大点的而且比较大众化的压力测试工具即可，以下跟大家交流下sysbench的安装和压力测试
sysbench支持以下几种测试模式：
1、CPU运算性能
2、磁盘IO性能
3、内存分配及传输速度
4、内存分配及传输速度
5、POSIX线程性能
6、数据库性能（OLTP基准测试）
目前sysbench主要支持mysql,drizzle,pgsql,oracle等几种数据库
下面安装sysbench
一、 下载源码包，安装epel包后以便安装bzr客户端：
[root ~]$ rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpmRetrieving http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpmwarning: /var/tmp/rpm-tmp.wgHSDP: Header V3 DSA/SHA1 Signature, key ID 217521f6: NOKEYPreparing... ########################################### [100%] 1:epel-release ########################################### [100%]
然后就可以开始安装bzr客户端了：
以下安装报错了：
[root yum.repos.d]$ yum install bzr Loaded plugins: fastestmirrorLoading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * epel: mirrors.ustc.edu.cn * extras: mirror.bit.edu.cn * updates: mirror.bit.edu.cnepel | 3.7 kB 00:00 Setting up Install ProcessResolving Dependencies--> Running transaction check---> Package bzr.x86_64 0:2.1.4-2.el5 will be installed--> Processing Dependency: python(abi) = 2.4 for package: bzr-2.1.4-2.el5.x86_64--> Processing Dependency: python-paramiko for package: bzr-2.1.4-2.el5.x86_64--> Processing Dependency: python-elementtree for package: bzr-2.1.4-2.el5.x86_64--> Running transaction check---> Package bzr.x86_64 0:2.1.4-2.el5 will be installed--> Processing Dependency: python(abi) = 2.4 for package: bzr-2.1.4-2.el5.x86_64--> Processing Dependency: python-elementtree for package: bzr-2.1.4-2.el5.x86_64---> Package python-paramiko.noarch 0:1.7.6-1.el5 will be installed--> Processing Dependency: python(abi) = 2.4 for package: python-paramiko-1.7.6-1.el5.noarch--> Finished Dependency ResolutionError: Package: bzr-2.1.4-2.el5.x86_64 (epel) Requires: python(abi) = 2.4 Installed: python-2.6.6-52.el6.x86_64 (@updates) python(abi) = 2.6 Available: python26-2.6.8-2.el5.x86_64 (epel) python(abi) = 2.6Error: Package: python-paramiko-1.7.6-1.el5.noarch (epel) Requires: python(abi) = 2.4 Installed: python-2.6.6-52.el6.x86_64 (@updates) python(abi) = 2.6 Available: python26-2.6.8-2.el5.x86_64 (epel) python(abi) = 2.6Error: Package: bzr-2.1.4-2.el5.x86_64 (epel) Requires: python-elementtree You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest
解决方法把旧版本的epel源删除，使用新的：（这个坑说白了，下载的epel源要跟自己使用系统符合，例如你用的是32位系统和64位的系统，下载epel源是不同的）
[root ~]$ cd /etc/yum.repos.d/[root yum.repos.d]$ lsCentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo epel.repo epel-testing.repo[root yum.repos.d]$ rm -rf epel.repo [root yum.repos.d]$ rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmRetrieving http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmwarning: /var/tmp/rpm-tmp.eyCDYb: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEYPreparing... ########################################### [100%] file /etc/yum.repos.d/epel-testing.repo from install of epel-release-6-8.noarch conflicts with file from package epel-release-5-4.noarch file /etc/yum.repos.d/epel.repo from install of epel-release-6-8.noarch conflicts with file from package epel-release-5-4.noarch
二、再安装安装bzr客户端：
[root yum.repos.d]$ yum install bzr -y.....
.......Running Transaction Installing : python-paramiko-1.7.5-2.1.el6.noarch 1/2 Installing : bzr-2.1.1-2.el6.x86_64 2/2 Installed: bzr.x86_64 0:2.1.1-2.el6 Dependency Installed: python-paramiko.noarch 0:1.7.5-2.1.el6 Complete!
之后就可以用bzr客户端下载sysbench源码了。
[root ~]$ bzr branch lp:sysbenchYou have not informed bzr of your Launchpad ID, and you must do this towrite to Launchpad or access private data. See "bzr help launchpad-login".Branched 128 revision(s).
[root ~]$ ll -d /root/sysbench/
drwxr-xr-x 7 root root 4096 11月 25 14:45 /root/sysbench/
可以看到，已经下载好sysbench目录了
三、 以下准备安装sysbench,涉及到sysbench源码的配置和编译，首先确认系统安装了gcc gcc-c++编译器:
[root sysbench]$ yum install autoconf automake libtool make cmake gcc gcc-c++ gcc4 -y
[root sysbench]$ pwd
/root/sysbench
[root sysbench]$ ./autogen.sh
查看./counfiure支持的选项再进行编译安装：
[root sysbench]$ ./configure --help | grep with | grep mysql
--with-mysql compile with MySQL support (default is enabled)
--with-mysql-includes path to MySQL header files
--with-mysql-libs path to MySQL libraries
[root sysbench]$ ./configure --with-mysql=/usr/local/mysql-5.5.40/ --with-mysql-includes=/usr/local/mysql-5.5.40/include/ > --with-mysql-includes=/usr/local/mysql-5.5.40/include/ > --with-mysql-libs =/usr/local/mysql-5.5.40/lib/
[root sysbench]$ make && make insall
第二种安装方法：
在 http://sourceforge.net/projects/sysbench 下载sysbench的源码包。
也可以在大牛的MySQL中文网上下载：http://imysql.com/wp-content/uploads/2014/09/sysbench-0.4.12-1.1.tgz
[root src]$wget http://imysql.com/wp-content/uploads/2014/09/sysbench-0.4.12-1.1.tgz
[root src]$ tar zxf sysbench-0.4.12-1.1.tgz[root sysbench-0.4.12-1.1]$ lsaclocal.m4 autom4te.cache config config.status configure.ac doc libtool Makefile Makefile.in mkinstalldirs README-WIN.txt TODOautogen.sh ChangeLog config.log configure COPYING install-sh m4 Makefile.am missing README sysbench[root sysbench-0.4.12-1.1]$ ./autogen.sh
[root sysbench-0.4.12-1.1]$./configure --with-mysql=/usr/local/mysql-5.5.40/ --with-mysql-includes=/usr/local/mysql-5.5.40/include/ \
> --with-mysql-includes=/usr/local/mysql-5.5.40/include/ \
> --with-mysql-libs =/usr/local/mysql-5.5.40/lib/
[root sysbench]$ make && make insall
以上的安装只是下载方式不同，安装都是一样的^.^
四、下面进行使用说明：
测试磁盘IOPS可以分为：prepare、run、cleanup三个阶段：（准备数据、运行压测、清理数据）
创建测试数据库：
mysql> create database sbtest;Query OK, 1 row affected (0.08 sec)mysql>
[root sysbench]$ pwd/root/sysbench-0.4.12-1.1/sysbench [root sysbench]$ ./sysbench --mysql-host=localhost --mysql-port=3308 --mysql-user=root --mysql-password=123456 --mysql-socket=/data/mysql-5.5/mysql.sock > --test=tests/db/oltp.lua --oltp_tables_count=10 --oltp-table-size=50000 --rand-init=on prepare
若运行过程报以下错：
./sysbench: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory解决方法：ln -s /usr/local/mysql-5.5.40/lib/libmysqlclient.so.18 /usr/lib64/
关于这几个参数的解释：
--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=50000 表示每个测试表填充数据量为 50000 --rand-init=on 表示每个测试表都是用随机数据来填充的五、进行OLTP测试
./sysbench --mysql-host=localhost --mysql-port=3308 --mysql-user=root --mysql-password=123456 --mysql-socket=/data/mysql-5.5/mysql.sock > --test=tests/db/oltp.lua --oltp_tables_count=10 --oltp-table-size=50000 --num-threads=8 > --oltp-read-only=off --report-interval=10 --rand-type=uniform --max-time=5 --max-requests=0 --percentile=99 run参数解释：
--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=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%里取最大值六、结果解读：

测试建议：
1、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。
2、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。
