sysbench安装、使用、结果解读
sysbench是一个模块化的、跨平台、多线程基准测试工具,主要用于评估测试各种不同系统参数下的数据库负载情况。
sysbench支持以下几种测试模式:
1、CPU运算性能
2、磁盘IO性能
3、调度程序性能
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。
安装
yum install m4 autoconf automake libtool mysql-community-devel
git clone https://github.com/akopytov/sysbench.git
cd /sysbench
./autogen.sh
./configure --with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib
make &&make install

OLTP测试前准备
初始化测试库环境(总共10个测试表,每个表 100000 条记录,填充随机生成的数据):
先创建测试数据库oo create databases foo;
sysbench --db-driver=mysql --mysql-user=root --mysql-password=123456 \
--mysql-db=foo --range_size=100 \
--table_size=1000000 --tables=10 --threads=8 --events=0 --time=60 \
--rand-type=uniform /usr/local/src/sysbench/src/lua/oltp_read_only.lua prepare
OLTP测试
sysbench --db-driver=mysql --mysql-user=root --mysql-password=123456 \
--mysql-db=foo --range_size=100 \
--table_size=1000000 --tables=10 --threads=8 --events=0 --time=60 \
--rand-type=uniform /usr/local/src/sysbench/src/lua/oltp_read_only.lua run >./sysbench_oltp.log
即:模拟 对10个表并发OLTP测试,每个表1000万行记录,持续压测时间为 1小时。
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。
