CentOS使用yum安装php性能测试工具xhprof
1.首先我们安装xhprof:
yum install xhprof
2.安装好之后,找到xhprof的配置文件xhprof.conf,一般会在/etc/php.d里面,加入这2行:
extension=xhprof.soxhprof.output_dir=<directory_for_storing_xhprof_runs>
3.如果要图形话,需要安装dot(可选):
yum install graphviz
4.安装好之后重启一下服务器:
service httpd restart
5.使用的话只要包含以下文件代码即可:
#在php的头部加上,可以设置记录频率,比如记录万分之一xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);
#在代码页的底部加上if ($xhprof_flag) { $xhprof_data = xhprof_disable(); include_once "./xhprof_lib/utils/xhprof_lib.php"; include_once "./xhprof_lib/utils/xhprof_runs.php"; $xhprof_runs = new XHProfRuns_Default(); $xhprof_runs->save_run($xhprof_data, 'xhprof',"index_".time());}
上面的xhprof_lib,php和xhprof_runs.php这2个文件的路径要改成自己的路径,千万不要写错,如果找不到这两个文件,可以使用指令 whereis xhprof 该指令会把xhprof相关的路径都罗列出来,你可以一一查询。?
6.把xhprof_html文件夹拷贝到你的web服务器根目录下,用来访问那些生成的文件;当有该php的访问时,会在
