MYSQL教程sysbench对mysql压力测试的详细教程

MYSQL应用
// 先安装编译依赖环境
$ sudo yum install gcc gcc-c++ automake make libtool mysql-community-devel
$ cd /tmp && git clone https://github.com/akopytov/sysbench.git
$ cd /tmp/sysbench && ./autogen.sh
$ ./configure --prefix=/usr/local/sysbench-0.5
$ ./make && sudo make install
// 0.5版本需要oltp.lua测试脚本
// 如果是rpm包方式安装的,在 /usr/share/doc/sysbench/tests/db/ 下可找到
$ cd /usr/local/sysbench && sudo mkdir -p share/tests/db
$ cp /tmp/sysbench/sysbench/tests/db/*.lua share/tests/db/
$ ./bin/sysbench --version
