SAE php 研究（2）

1.在SAE新建项目打印出phpinfo
<?php 
print phpinfo();
?>
2.
可见:PHP Version 5.3.8
【使用的是php5.3.8编译的】
3.
可见:
System SAE LINUX ENVIRONMENT
Build Date May 19 2013 
【说明是一台共享的虚拟机，创建于2013.05.19】
4.
可见:Thread Safety disabled
【可能使用的是fastcig模式】
5.
可见:
Zend Memory Manager enabled
Zend Multibyte Support disabled
IPv6 Support disabled
Registered PHP Streams compress.zlib, php, file, glob, data, zip, http, https, saemc, saestor, saekv
Registered Stream Socket Transports tcp, udp, unix, udg, ssl, sslv3, sslv2, tls
Registered Stream Filters zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*
6.
可见:
apache2handler
【说明使用了--with-apxs2[=FILE]   参数】
7.
可见:
Max Requests Per Child: 256 - Keep Alive: off - Max Per Connection: 100
【
该apache限制为每个子进程可以处理256次请求，每个线程最大连接数为100
进程数的最大值由MaxClients控制，在Apache1.3中最大只能设置为256，但在Apache2.0中，可以通过在配置开头增加ServerLimit项目来突破256的限制，此时必须MaxClients ≤ ServerLimit ≤ 20000
MaxRequestsPerChild用来控制每个进程在处理了多少次请求之后自动销毁
Keep Alive: off
】
8.
可见:
Timeouts Connection: 20 - Keep-Alive: 5
【
MaxVhostClients  100 
Keep-Alive: 5 这个应该没意义，因为Keep Alive: off
】
9.
可见:
Loaded Modules core prefork http_core mod_so mod_mime mod_dir mod_log_config mod_setenvif mod_headers mod_filter mod_deflate mod_rewrite mod_php5 mod_extract_forwarded mod_usertrack mod_saestat mod_saeenv mod_auth_basicx mod_authz_hostx mod_authn_memory mod_authz_user mod_appconfig mod_applimit mod_execlimit mod_appsense
