SAE php 研究（2）

1.在SAE新建項目打印出phpinfo
<?php 
print phpinfo();
?>
2.
可見:PHP Version 5.3.8
【使用的是php5.3.8編譯的】
3.
可見:
System SAE LINUX ENVIRONMENT
Build Date May 19 2013 
【說明是一臺共享的虛擬機，建立於2013.05.19】
4.
可見:Thread Safety disabled
【可能使用的是fastcig模式】
5.
可見:
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.
可見:
apache2handler
【說明使用了--with-apxs2[=FILE]   參數】
7.
可見:
Max Requests Per Child: 256 - Keep Alive: off - Max Per Connection: 100
【
該apache限制爲每一個子進程能夠處理256次請求，每一個線程最大鏈接數爲100
進程數的最大值由MaxClients控制，在Apache1.3中最大隻能設置爲256，但在Apache2.0中，能夠經過在配置開頭增長ServerLimit項目來突破256的限制，此時必須MaxClients ≤ ServerLimit ≤ 20000
MaxRequestsPerChild用來控制每一個進程在處理了多少次請求以後自動銷燬
Keep Alive: off
】
8.
可見:
Timeouts Connection: 20 - Keep-Alive: 5
【
MaxVhostClients  100 
Keep-Alive: 5 這個應該沒意義，由於Keep Alive: off
】
9.
可見:
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
