安装环境
centos7
apache2.4
php5.4
均使用YUM安装。
默认配置。
创建phpinfo
echo "<?php phpinfo(); ?>" >> /home/www/html/index.php
使用ab，phpinfo进行测试
出现socket错误继续进行（-r Don‘t exit on socket receive errors.）
第一次测试
ab -r -n 20000 -c 2000 ‘http://127.0.0.1/index.php‘
测试期间，新建一个会话，统计httpd进程数。
ps -ef|grep httpd|wc -l 259
最多的时候是259个进程，基本符合默认配置最多256个httpd进程
