mysql sysbench多表测试

 

mysql数据库性能测试工具比较多，本文主要讲下sysbench测试mysql。

sysbench在0.5以前是不支持多表测试，0.5版本以后才支持，因为我的mysql是自己编译的，yum安装sysbench0.5找不到mysql类库，所以采用了，sysbench-0.4.12加sysbench-db-scripts这个升级包，使其支持多表测试。

#下载sysbench-0.4.12源码包

 

#安装编译包

yum install libtool

#下载升级包源码要通过bzr获取

#bzr branch lp:~vadim-tk/sysbench/sysbench-db-scripts

./autogen.sh

cp /usr/bin/libtool .

./configure –prefix=/tmp/sysbench-0.4.12 –with-mysql –with-mysql-includes=/u01/mysql/include/ –with-mysql-libs=/u01/mysql/lib ;

make -j 8

sudo make install

sudo cp -r sysbench/tests/ /tmp/sysbench-0.4.12/bin/

cd /tmp/sysbench-0.4.12/bin/

然后在mysql中创建sbtest库

#导数据 耗时较长

./sysbench --test=tests/db/oltp.lua --max-time=30 --oltp-dist-type=uniform --max-requests=0 --mysql-user=root --mysql-table-engine=innodb --oltp-table-size=30000000  --num-threads=100 --mysql-socket=/tmp/mysql.sock --oltp-read-only=on prepare

#开始测试

./sysbench --test=tests/db/oltp.lua --max-time=30 --oltp-dist-type=uniform --max-requests=0 --mysql-user=root --mysql-table-engine=innodb --oltp-table-size=30000000  --num-threads=100 --mysql-socket=/tmp/mysql.sock --oltp-read-only=on run 

#清除数据

./sysbench --test=tests/db/oltp.lua --max-time=30 --oltp-dist-type=uniform --max-requests=0 --mysql-user=root --mysql-table-engine=innodb --oltp-table-size=30000000  --num-threads=100 --mysql-socket=/tmp/mysql.sock --oltp-read-only=on cleanup

#数据结果分析
