第一步，下载安装。登陆我们VPS SSH然后下载UnixBench。
wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz
tar xvfz unixbench-5.1.2.tar.gz
cd unixbench-5.1.2
如果不需要测试图形，注释掉Makefile文件的这一行
#GRAPHIC_TESTS = defined
./Run
第二步，通过上面的命令，UnixBench就开始运行了，运行时间比较久估计十几分钟。我们可以做点其他事情等待结果。最后会有一个综合打分。
这里可能有的机器会有一些问题
第一、如果在MAKE的时候出现GCC错误：
make: gcc: Command not found
make: *** [pgms/arithoh] Error 127
我们需要安装gcc
yum install gcc
然后我们才好make下一步，如果是debian应该是apt-get.
总结，有高人说一般100分以上的是值得购买的，低于100分直接PASS。性能稍微好点的VPS 400分左右。
第二、有人博文说到会有Error: Please install /usr/bin/time提示错误，解决方法是：
#centos/fedora 下运行
yum install time
#ubuntu/debian 下运行
apt-get install time
第三、Can't locate Time/HiRes.pm错误解决
有的时候在运行./Run时候会出现这样的错误
Can't locate Time/HiRes.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./Run line 6.
BEGIN failed--compilation aborted at ./Run line 6.
解决方案也简单，只需要安装组件
yum install perl-Time-HiRes
运行安装之后我们再运行./Run就可以。
第四、如果出现bash: make: command not found问题
yum -y install gcc automake autoconf libtool make
运行安装，然后我们make之后再./Run执行。
