今天在編譯apache時，出現如下問題：

make[3]: Entering directory `/tmp/httpd-2.2.22/srclib/apr-util/xml/expat'
/bin/sh ./conftools/mkinstalldirs /usr/local/apache2/lib /usr/local/apache2/include

卡在這裡編譯不過去了，分析原因，原來是缺少 apr & apr-util，下面我們就來解決該問題。

需要下載以下兩個包：

執行以下命令：

    >wget http://mirror.bjtu.edu.cn/apache//apr/apr-1.4.5.tar.gz
　　>tar zxvf apr-1.4.5-tar.gz
　　>cd apr-1.4.5
　　>./configure --prefix=/usr/local/apr-httpd/
　　>make
    >make install

    >wget http://mirror.bjtu.edu.cn/apache//apr/apr-util-1.4.1.tar.gz
　　>tar zxvf apr-util-1.4.1-tar.gz
　　>cd apr-util-1.4.1
　　>./configure --prefix=/usr/local/apr-util-httpd/ --with-apr=/usr/local/apr-httpd/
　　>make
    >make install

　　回到apache編譯目錄

　　>./configure --prefix=/usr/local/apache2 --sysconfdir=/etc/httpd --with-z=/usr/local/zlib --with-apr=/usr/local/apr-httpd --with-apr-util=/usr/local/apr-util-httpd  --disable-userdir --enable-so --enable-deflate=shared --enable-expires=shared --enable-rewrite=shared --enable-static-support
　　>make
　　>make install

    啟動apache服務

    >/usr/local/apache2/bin/apachectl start

現在可以了，輸入http://loaclhost/訪問試試！
