【1】下载安装 sysbench
GITHub: https://github.com/akopytov/sysbench
【1.1】yum安装 sysbench
curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.deb.sh | sudo bash sudo apt -y install sysbench
# sudo yum -y install sysbench
核验,sysbench --version ,sysbench --help
默认位置在 /usr/sysbench
【1.2】编译安装
下载解压
wget https://github.com/akopytov/sysbench/archive/1.0.zip -O "sysbench-1.0.zip" unzip sysbench-1.0.zip
安装
(1)基本安装
yum -y install make automake libtool pkgconfig libaio-devel cd sysbench-1.0 ./autogen.sh
(2)检查mysql环境
rpm -qa |grep -i mysql rpm -ql mysql-community-libs rpm -ql mysql-community-devel
(3)没有Mysql包的话要安装,如果(2)中有的话,请忽略
https://centos.pkgs.org/7/mysql-8.0-x86_64/mysql-community-devel-8.0.22-1.el7.x86_64.rpm.html Download latest mysql80-community-release-el7 rpm from http://repo.mysql.com/ # wget http://repo.mysql.com/mysql80-community-release-el7.rpm Install mysql80-community-release rpm: # rpm -Uvh mysql80-community-release*rpm Install mysql-community-devel rpm package: # yum --enablerepo=mysql80-community install mysql-community-devel -y
(4)安装
#结合mysql用的话要这样
./configure --prefix=/usr/local/sysbench --with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib ,这个路径可以从上面的rpm -ql mysql_comunity-libs 之类的拿到 make make install
说明: --prefix=/usr/sysbench/ :指定sysbench的安装目录。 --with-mysql-includes=/usr/include/mysql/ :指定安装mysql时候的includes目录。 --with-mysql-libs=/usr/lib/mysql/ :指定装mysql时候的lib目录。 --with-mysql :sysbench默认支持mysql,如果需要测试oracle或者pgsql则需要制定–with-oracle或者–with-pgsql。
(5)核验:
添加到环境变量:
echo "export PATH=$PATH:/usr/local/sysbench/bin" >>/etc/profile
source /etc/profile
注意:如果要测试哪个盘,就要切换目录到哪个盘,然后构造测试数据,见【6】
【1.3】安装 sysbench-tpcc
官方主页:https://github.com/Percona-Lab/sysbench-tpcc
Percona安装源(yum源) [root@zhumh ~]# wget https://www.percona.com/redir/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm [root@zhumh ~]# yum -y install percona-release-0.1-6.noarch.rpm [root@zhumh ~]# yum -y install sysbench [root@zhumh ~]# yum -y install sysbench-tpcc
【1.4】结合mysql安装,最佳实践
centos 7.6 git clone https://github.com/akopytov/sysbench.git cd sysbench 使用mysql-community.repo yum install m4 autoconf automake libtool mysql-devel 找到和/usr/lib64/mysql/libmysqlclientx 所在的目录 /usr/include/mysql和/usr/lib64/mysql rpm -qa |grep -i mysql rpm -ql mysql-community-libs rpm -ql mysql-community-devel ./autogen.sh ./configure --with-mysql-includes=/usr/include/mysql --with-mysql-libs=/usr/lib64/mysql --prefix=/data/sysbench make && make install 测试数据 ./bin/sysbench /data/sysbench/share/sysbench/oltp_insert.lua --tables=10 --mysql-user=root --mysql-password=bfgame20 --mysql-db=mytest --mysql-socket=/data/mysql/mysql.sock --threads=20 --events=500000000 --time=0 run --mysql-host IP --mysql-port 端口号 --mysql-db 希望链接的数据库 --mysql-user 用户名 --mysql-password 密码 --table_size 每张表初始化的数据数量 --tables 初始化表的数量 --threads 启动的线程 --time 运行时间设为0表示不限制时间 --report-interval 运行期间日志,单位为秒 --events 最大请求数量,定义数量后可以不需要--time选项

【3】使用方法
【3.1】命令格式与常规语法
sysbench [options]... [testname] [command]
常规语法:
-
testname:是的内置测试(例如,一个可选的名字
fileio
,memory
,cpu
等),或捆绑的Lua脚本之一(例如的名称oltp_read_only
),或者路径到自定义Lua中。如果在命令行上未指定测试名称(因此也没有 命令,因为在这种情况下它将被解析为testname),或者测试名称是破折号(“-
”),则sysbench期望使用Lua脚本以在其标准输入上执行。 -
command:是一个可选参数,它将由sysbench传递给用testname指定的内置测试或脚本。命令 定义测试必须执行的操作。可用命令的列表取决于特定的测试。一些测试还实现了自己的自定义命令。
以下是典型测试命令及其用途的说明:
prepare
:生成测试所需要的数据,例如在磁盘上创建测试所需的文件fileio
,或为数据库基准测试填充测试数据库。run
:进行性能测试,运行使用testname 参数指定的实际测试。所有测试均提供此命令。cleanup
:清除测试数据,在创建一个测试的那些测试中运行后删除临时数据。help
:显示使用testname参数指定的测试的使用信息 。这包括测试提供的命令的完整列表,因此应使用它来获取可用的命令。
-
options:是以开头的零个或多个命令行选项的列表
'--'
。与命令一样,该sysbench testname help
命令应用于描述特定测试提供的可用选项。有关 sysbench本身提供的常规选项的说明,请参见常规命令行选项。
您可以sysbench --help
用来显示常规命令行语法和选项。
【3.2】Testname
包含2种,内建脚本和Lua脚本
- sysbench可以实现如下基准测试:
- oltp_*.lua: OLTP类的数据库基准测试;
- fileio:文件系统的(IO)基准测试;
- cpu: 简单的CPU基准测试;
- memory: 内存访问基准测试;
- threads: 基于线程的调度基准测试;
- mutex: POSIX互斥量基准测试
ll /usr/share/sysbench/ ,这是yum安装生成的
如果是我们编译安装的,则会在指定目录下的 share/sysbench
