sudo wget http://pecl.php.net/get/xhprof
chmod 777 xhprof
tar zxf xhprof
cd xhprof-0.9.2
sudo su
#安装php5-dev
apt-get install php5-dev
如果上面的有错误则用这个:
apt-get update
apt-get install php5-dev --fix-missing
cd extension/
phpize
#下一步非常重要:
./configure -with-php-config=/usr/bin/php-config
make&&make install
make test
然后找到php.ini
添加:
[xhprof]
extension=xhprof.so
;#
;# directory used by default implementation of the
iXHProfRuns
;# interface (namely, the XHProfRuns_Default class) for
storing
;# XHProf runs.
;#
xhprof.output_dir=/var/log/xhprof/
创建目录
sudo mkdir /var/log/xhprof
更改目录权限
sudo chown www-data:www-data /var/log/xhprof
安装graphviz ,以图形形式查看结果
apt-get install graphviz
重起apache2,查看phpinfo,出现xhprof的配置
