源码安装
安装方法参见： https://github.com/akopytov/sysbench
源码编译的安装步骤如下：
yum -y install make automake libtool pkgconfig libaio-devel openssl-devel wget https://github.com/akopytov/sysbench/archive/master.zip unzip master.zip cd sysbench-master/ ./autogen.sh ./configure --without-mysql make -j make install
没有安装mysql，所以要用–without-mysql。
