今天回来发现apache不能启动了，郁闷，报的错误是mod_ssl无法加载，我把#LoadModule ssl_module modules/mod_ssl.so加截ssl的地方注释掉就好了。以前都配置好了的，今天怎么会不行了呢？我又重新把mod_ssl编译了一下，
cd /apache的解压目录／modules/ssl
[root@BlackGhost ssl]# /usr/local/apache/bin/apxs -c -i mod_ssl.c
ssl_private.h:541:14: error: declaration for parameter 'ssl_hook_UserCheck' but no such parameter
ssl_private.h:540:14: error: declaration for parameter 'ssl_hook_Auth' but no such parameter
ssl_private.h:537:14: error: declaration for parameter 'ssl_init_ModuleKill' but no such parameter
ssl_private.h:536:14: error: declaration for parameter 'ssl_init_Child' but no such parameter
mod_ssl.c:520:1: error: expected '{' at end of input
apxs:Error: Command failed with rc=65536
上面的报错只是最下面的一部分，搞了好长时间，没搞定，决定下个新的apache重装一下，顺便把安装过程说一下
一，安装httpd-2.2.16.tar.gz
wget http://www.apache.org/dist/httpd/httpd-2.2.16.tar.gz
tar zxvf httpd-2.2.16.tar.gz
cd httpd-2.2.16
./configure --prefix=/usr/local/apache --enable-ssl --enable-so --with-ssl=/us
make && make install
1，改documentroot和<Directory "/home/zhangy/www">，把里面的默认路径改成你的web目录。
2，加载libphp.so
我记得以前装php的时候，会自动添加好下面的东西，但是这次我只升级apache，我还没找到libphp.c文件在什么地方，没法用apxs来重新编译，还是用以前的libphp5.so吧
LoadModule php5_module modules/libphp5.so
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps
AddType application/x-httpd-php .php
如果不加上面的东西，php代码无法解悉，会直接把源码显示出来
3，修改user和group，你看一下user后面的用户，在你的系统中有没有，如果没有的话，你启动apache后，查看页面时会forbidden错误，改成你指定的用户，当然这个用户必有在你的系统中。
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User zhangy
Group users
二，编译mod_ssl模块看看报不报错
cd /apache的解压目录／modules/ssl
/usr/local/apache/bin/apxs -c -i mod_ssl.c
make && make install
下面是安装时候显示出来的信息
Libraries have been installed in:
/usr/local/apache/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
chmod 755 /usr/local/apache/modules/mod_ssl.so
现在编译就没有报错了，我觉得肯定是因为我升级的原因，并且只是升级了一部分。安装的时候，我已经内建了mod_ssl所以就不用在加载了。如果加了的话，会提示module ssl_module is built-in and can't be loaded
[root@BlackGhost misc]# /usr/local/apache/bin/apachectl configtest
Syntax OK
