请问Apache安装后怎样再加入新模块

用tar包安装Apache，在后来使用中发现没有mod_dav模块，请问怎么才能在不影响正常使用的情况下加入对该模块的支持

用tar包安装Apache，在后来使用中发现没有mod_dav模块，请问怎么才能在不影响正常使用的情况下加入对该模块的支持

首先问楼主，tar安装编译的时候，是否 --enable-so ?
只有编译的时候，加入此项，才可以动态加载模块

我只在编译时加入了enable-modules选项，是不是我要实现mod_dav的支持，必须要重新编译安装呀？

1. 我只在编译时加入了enable-modules选项，是不是我要实现mod_dav的支持，必须要重新编译安装呀？

复制代码

不需要重装apache
编译 mod_dav得到模块，在httpd.conf 加入模块读取，就Ok

再请教楼上的大哥，我下载mod_dav的tar包后安装，无法编译通过，看说明是缺少expat文件，再下载expat文件夹，如下
[root@server expat]# ls
bin        expat.html  lib       sample    xmltok
expat.dsw  gennmtab    Makefile  xmlparse  xmlwf

按照mod_dav对expat有如下说明

For Unix
          Note that the expat Makefile does not automatically build the
          expat library. Add this rule to the Makefile:

  libexpat.a: $(OBJS)
        ar -rc $@ $(OBJS)
        ranlib $@

          (don't forget to use tabs before the ar and ranlib lines there)

          Then type: make libexpat.a
但我半天也不明白
         
        libexpat.a: $(OBJS)
        ar -rc $@ $(OBJS)
        ranlib $@

          (don't forget to use tabs before the ar and ranlib lines there)
这些话是什么意思，能不能给指点下，谢谢

能把编译过程帖一下吗？

这是编译mod_dav的结果
[root@server mod_dav-1.0.3-1.3.6]# ./configure --with-apxs=/usr/local/apache2/bin/apxs

    more information.
下边是不管mod_dav中的说明直接运行expat中 Makefile的结果

下边是mod_dav中install的部分关于expat的说明
Note: sometimes, the APXS installation may be broken. If the
     configure process reports this, then please refer to a [10]FAQ
     entry written by the PHP folks. It explains the problem quite well.

          The configuration process will do its stuff. One of its tasks
          is to locate the Expat library (an XML parsing library). This
          library is included with Apache 1.3.9 and will automatically be
          found. If you have a previous version of Apache 1.3 (it must be
          at least Apache 1.3.4), then you will need a copy on your
          system. configure will look for it in /usr/{include,lib} and in
          /usr/local/{include,lib}. If it can't find it, then you will
          need to tell configure where it is on your system using the
          --with-expat=<dir> command line option. For example:

     ./configure --with-apxs=/usr/local/apache/bin/apxs
     --with-expat=/home/gstein/expat
