标题: linux+apache不稳定求解
我采用centos4.1（redhat as4 x64版）做为服务器，服务器配置为intel 64位双至强。

软件为apache＋mysql＋php。

系统负荷常常会一下子冲到40多，甚至200、300，打开网页非常非常慢，有时打不开，用top查看可看到cpu行wa非常高（wa不知是什么，可有哪位高人告知）

有时系统负荷高一下后，又很低了，但网页又打不开，ps看apache进程可发现256个apache进程全部在启动。重启apache后就正常了。想来可能是apache死锁。。。

现在的系统几乎要值守，简直比window还window ，而另一台freebsd的（访问量低点）倒稳定的出奇，几乎0维护。现在系统正在使用中，又不好重装。

哪位请指点一下，如何让系统稳定点。

试过apache2,apache1

另外，在系统上手工编译mysql，总是编出多进程的mysql，编译不出linux多线程（当时采用linux，就是为这个特征啊，

），在本地用centos4.2就可以编译出来, 不知为何？

一个top输出：

可能是你没有配置好，或存在着一些外部因素，比如攻击，

个人认为,Linux可能会没有BSD稳定，linus都说现在的内核代码比较乱，但也至于这么糟的。

作者: anthonyfeng 时间: 2006-06-12 12:08
wa 是 wait i/o ，高的话，大概就是指cpu 花大量resource 在等待数据

有些内核问题很多.

呵呵，若不稳定就改用别的好了。

而另一台freebsd的（访问量低点）倒稳定的出奇，几乎0维护

这就是为什么

不同的访问量，无可比性
可能存在攻击，无可比性
从不知道 wa 是什么来推断，你对 Linux 不熟且不擅长使用搜索引擎，可见能力存在一定问题，APM 配置是否有问题无从考证

试想，若 FreeBSD 那台访问量很大，且可能正在被 CC 攻击，而 Linux 那台访问量很小，负载很低
那么，是不是你就要说“FreeBSD 几乎要一直有人职守，而 Linux 倒稳定的出奇，几乎 0 维护”了？ :wink:

作者: 林泥克斯 时间: 2006-06-13 08:24
apm是指电源管理吗？这个要怎么配置？

作者: hongfengyue 时间: 2006-06-13 08:53
楼上的，到Google搜索apache mpm就知道了。

作者: suran007 时间: 2006-06-13 10:36
请楼主讲mpm部分贴出来

本人愚钝,各位见笑了, 自觉unix知识尚可,google也搜了好久了,但没有搜到详细介绍wa的, 请介绍一个有wa详细介绍的和优化wa过高(包括硬件)的网址?

我这个linux系统系统上基本没有配置过. 就sysctl改过,附后

遇到这种问题,确实叫人纳闷. 请帮忙如何解决这个问题. 谢谢, 我会记住你的.

freebsd也放过这个网站, 由于配置比较低,在高负荷时,系统会自动重启(后移这个网站到独立服务器上), 但还没用发现负荷不高时,拒绝服务的情况, linux上有时拒绝服务时,系统负荷较并不高.用以下命令守值发现不太象有攻击
netstat -an --tcp | grep ":80" | grep ESTABLISHED | awk '{printf "%s %s\n",$5,$6}' | sort
tcpdump | grep "> xx.x.xx.xxx.http"

另外本linux系统为64位系统,centos4.1, 是否64位稳定性也差低?

好的os要用会的人才行，楼上的多看看redhat的文档吧。

从目前表现看apache1和apache2差不多,好像apache1稍好点

apache2 mpm设置:
<IfModule worker.c>
StartServers       4
ServerLimit       12
ThreadLimit       256
MaxClients       576
MinSpareThreads    64
MaxSpareThreads    128
ThreadsPerChild    64
MaxRequestsPerChild 50000
</IfModule>

现在用apache1, 设置如下:
MinSpareServers 10
MaxSpareServers 50
StartServers 5
MaxClients 512
MaxRequestsPerChild 1000

曾怀疑有攻击, 但发现很奇怪现象,有时在某些机器上不可访问, 而且也没用收到受攻击警告,设置如下
<IfModule mod_evasive.c>
DOSHashTableSize 3097
DOSPageCount       2
DOSSiteCount       50
DOSPageInterval    1
DOSSiteInterval    1
DOSBlockingPeriod 10

DOSEmailNotify    zhien@xx.com
#DOSSystemCommand "su - someuser -c '/sbin/... %s ...'"
DOSLogDir          "/var/log/httpd/mod_evasive"
</IfModule>

linux内核(没用重新编译过):
uname -a
Linux www 2.6.9-11.ELsmp #1 SMP Wed Jun 8 16:59:12 CDT 2005 x86_64 x86_64 x86_64 GNU/Linux

apache1和apache2都是手动编译的,编译参数:
apache_1.3.34
./configure \
"--with-layout=Apache" \
"--prefix=/usr/local/apache1" \
"--sysconfdir=/usr/local/etc/apache1" \
"--localstatedir=/var/log/httpd" \
"--activate-module=src/modules/php4/libphp4.a" \
"--enable-module=rewrite" \
"--enable-module=expires" \
"--enable-module=vhost_alias" \
"--disable-module=imap" \
"--disable-module=status" \
"--disable-module=userdir" \

+mod_evasive防攻击
"--add-module=src/modules/evasive/mod_evasive.c" \

vi /soft/make/httpd-2.0.55/config.log
./configure --prefix=/usr/local/apache2 --enable-module=so --enable-mods-shared=all --with-mpm=prefork --enable-deflate --disabl
e-ipv6 --sysconfdir=/usr/local/etc/apache2 --localstatedir=/var/log/httpd

php:
./configure  --with-mysql=/usr/local/mysql --with-apxs2=/usr/local/apache2/bin/apxs --enable-track-vars --enable-force-cgi-redirect --enable-pic --enable-inline-optimiation --enable-memory-limit --enable-calendar --enable-mcal --with-config-file-path=/usr/local/etc --with-zlib-dir=/usr/include --disable-ipv6

装了eaccelerator-0.9.4,速度确实有提高,但高峰期,感觉稳定性还没有原来好,就卸载了

请看upload达52  wa:49 连续几分钟后upload降为3-20(一时高一时低),但页面响应速度还是有点慢.
重启apache,情况差不多,再重启mysql.upload降1-2,并稳定在1-2,页面响应速度有提高,但不是很明显

以下是一些输出,请帮忙看看, 谢谢.

另有一点须向大家说明:
这个服务器一般数据库都在2-5万条记录左右, 有6个表记录较多20万左右,另有一个表40多万记录,页面全部用php缓存,2个小时过期,php随访问更新. 搜索还是直接在数据库中进行.
