apache2加上php后一个httpd进程内存飙升到28M
在没有加上php之前,每个httpd进程所用的内存1M左右,但加上php后,内存达到28M,请问如何调整每个httpd的内存使用率?

谢谢

------解决方案--------------------
我本地还33M呢。应该正常吧。
------解决方案--------------------
查看apache的并发多进程模块,看是什么模式(work,prefork,mpm)。调整这个模块的最大子进程数。
具体可参考手册。

------解决方案--------------------
这几十m还想省多少啊。你机器多大内存啊。

这个跟apache的上述配置有关系吗?在没有加入php模块之前,每个httpd的进程内存是1M左右,加了php模块,就上升到28M,如何减少每个httpd进程所占用的内存?

------解决方案--------------------
apache安装上本身就有安装多进程的模块,mpm或者work,prefork。可以控制最大进程和线程数的。既然你内存不多,限制进程数未尝不是一个好方法。
------解决方案--------------------
可以查看下你的服务器进程数在什么数量级:

ps -ef |grep httpd |wc -l
------解决方案--------------------
仅仅是增加了php模块?将php里不需要的一些so扩展去掉看看是否有帮助。
------解决方案--------------------
好像是正常的吧!
