Configuring SAPI modules
checking for AOLserver support... no
checking for Apache 1.x module support via DSO through APXS...

Sorry, I was not able to successfully run APXS.  Possible reasons:

1.  Perl is not installed;
2.  Apache was not compiled with DSO support (--enable-module=so);
3.  'apxs' is not in your path.  Try to use --with-apxs=/path/to/apxs
The output of /usr/local/webserver/httpd20/bin/apxs follows
/usr/local/webserver/httpd20/bin/httpd: error while loading shared libraries: libiconv.so.2: cannot open shared ob
ject file: No such file or directory
apxs:Error: Sorry, no shared object support for Apache.

apxs:Error: the Apache module mod_so is compiled into.

运行 ldd /usr/local/webserver/httpd20/bin/httpd
提示找不到
libiconv.so.2 => not found

查找 libiconv.so.2 ,并复制到 httpd20/lib下,编译成功

把--with-apxs 改为 --with-apxs2
记得比较早以前,在apache2时是要加2的,但之前的好一段时间,似乎都没加也一样可以.有点糊涂了.

checking for termcap functions library... configure: error: No curses/termcap library found

安装 ncurses

还不行的话,加上 ./configure --with-named-curses-libs=/usr/lib/libncursesw.so.5

Notice: Following unknown configure options were used:

--with-png

--with-png-dir=/usr

./configure --prefix=/www/httpd --with-mpm=worker --enable-so --enable-rewrite --enable-cache --enable-mem-cache --enable-disk-cache --enable-static-htcacheclean  --enable-speling

php-5.2.8
checking for MySQL UNIX socket location... no
configure: error: Cannot find libmysqlclient_r under /www/servers/mysql4118.
Note that the MySQL client library is not bundled anymore!
要求mysql也要加上 --enable-thread-safe-client.
解决方法一：重新编译安装MYSQL的时候加上 --enable-thread-safe-client.
原因：--enable-thread-safe-client    #Compile the client with threads. 如果没有这个参数，编译php的时候会报"Cannot find libmysqlclient_r under”之类的错误。
其实这跟PHP没有关系
那是因为我在编译APACHE的时候，使用--with-mpm模块，所以就必须在编译MYSQL的时候加上 --enable-thread-safe-client.
这是PHP5.2的一个改进，在PHP5.2.0之前的版本都不需要MYSQL启用安全线程

解决方法二：编译之前，先处理一下mysql的库，默认查找libmysqlclient_r.so，可是mysql默认为libmysqlclient.so，内容完全一样，做个链接即可
# cd /data/mysql/lib/mysql/
# ln -s libmysqlclient.so.15.0.0 libmysqlclient_r.so
照做。
再次重新编译安装PHP
顺利通过！

php-5.2.8
[Fri Dec 19 15:55:51 2008] [crit] Apache is running a threaded MPM, but your PHP Module is not compiled to be thre
adsafe.  You need to recompile PHP.
Pre-configuration failed

编译apache启用了worker的mpm,编译PHP时就提示上面的.网上资料说,要在编译PHP也要加上相应的参数  --enable-maintainer-zts,但问题仍就,最后把apache的worker给取消就正常了.暂时试用段时间看

也就是不管最后后缀为什么，只要是.php.*结尾，且没在mime.types定义的,都将会被Apache服务器解析成php文件

这主要是对有上传功能的服务器比较危险,解决的办法是对允许上传的文件类型,在mime.types文件中定义即可,或者升级最新版本的apache,php

最近,FTP下载带宽太大,找了个限制带宽的,效果不错

http://ivn.cl/apache

http://ivn.cl/files/source/mod_bw-0.8.tgz

<VirtualHost *>
    BandwidthModule On
    ForceBandWidthModule On
    Bandwidth all 30720
    MinBandwidth all -1
</VirtualHost>

限制最大为30K

目前各种多线程下载工具泛滥，这对提供部分下载功能的网站来说是个比较头疼的问题，由于多线程下载会给服务器带来巨大的负载压力，而且可能会对整个站点产生影响，使其不能正常访问。那么有没有什么方法可以解决这些问题呢？答案是肯定的。目前国内大部分站点都是基于LAMP（Linux+Apache+Mysql+php）架构的，Apache是一个开源的，功能强大，稳定，使用量最大的WEB服务器。Apache是模块化开发的，可以根据需要增加各种功能模块，这里我给大家介绍两个模块，一个是mod_limitipconn，另一个是bw_mod。

一、mod_limitipconn

二、bw_mod

日志里显示

Cannot allocate memory: apr_thread_create: unable to create worker thread

调整 ThreadsPerChild 参数

早在04年初的时候,就知道apache能配置大型的虚拟主机.比如那些提供免费空间的.因为当时所在的公司就有这个提供.但自己当时也没怎么去留意.这种配置可以少去很多烦琐的工作.配置也分好多种.这里所说的是针对二级域名的.比如 abc.51099.com

前几天测试,还以为一个IP,只能配置一个这样的动态应用,还在想,应该也能支持多个以上.今天有空又再测试一下.果真是没问题的.只要相应的配置servername/serveralias就可以了

因为迟点会做一个相应关的项目.呵呵,真爽

apache文件所在目录 modules/metadata/mod_expires.c

编译，使用apxs工具

apachepath/bin/apxs -c -i -a mod_expires.c

 编译完后，自动加了LoadModule

httpd.conf配置

<IfModule expires_module>
    ExpiresActive On
    ExpiresByType image/gif "access plus 300 minutes"
    ExpiresByType image/jpeg "access plus 300 minutes"
    ExpiresByType image/png "access plus 300 minutes"
    ExpiresByType text/css "access plus 3 minutes"
    ExpiresByType application/x-shockwave-flash "access plus 300 minutes"
    #ExpiresByType image/gif "access plus 3 minutes"
    #ExpiresByType image/jpeg "access plus 3 minutes"
