1 -- SSLPassPhraseDialog

apache按如下配置安装：

$ ./configure --prefix=/home/svn/apps/apache --with-apr=/home/svn/apps/apr --with-apr-util=/home/svn/apps/apr-util --with-ssl=/home/svn/apps/ssl

所有软件安装完毕后，开始启动apache，启动的时候发现如下错误：

linux-rwdx:/home/svn/apps/apache/bin # ./apachectl start
Syntax error on line 56 of /home/svn/apps/apache/conf/extra/httpd-ssl.conf:
Invalid command 'SSLPassPhraseDialog', perhaps misspelled or defined by a module not included in the server configuration

错误原因，使用“./httpd -t -D DUMP_MODULES”命令查看apache已安装的模块，发现apache没有加载mod_ssl模块，所以我们重新编译安装。在配置选项上加入“--enable-ssl”：

shell# ./configure --prefix=/home/svn/apps/apache --with-apr=/home/svn/apps/apr --with-apr-util=/home/svn/apps/apr-util --with-ssl=/home/svn/apps/ssl --enable-ssl

2 -- dav_xml_get_cdata

apache按如下配置安装：

$ ./configure --prefix=/home/svn/apps/apache --with-apr=/home/svn/apps/apr --with-apr-util=/home/svn/apps/apr-util --with-ssl=/home/svn/apps/ssl --enable-ssl

安装完毕后，启动apache，提示如下错误：

linux-rwdx:/home/svn/apps/apache/bin # ./apachectl start
httpd: Syntax error on line 55 of /home/svn/apps/apache/conf/httpd.conf: Cannot load /home/svn/apps/apache/modules/mod_dav_svn.so into server: /home/svn/apps/apache/modules/mod_dav_svn.so: undefined symbol: dav_xml_get_cdata

apache编译的时候必须加上“--enable-dav”和“--enable-so”选项：

shell# ./configure --prefix=/home/svn/apps/apache --with-apr=/home/svn/apps/apr --with-apr-util=/home/svn/apps/apr-util --with-ssl=/home/svn/apps/ssl --enable-ssl --enable-dav --enable-so
