今天从Apache官网上http://httpd.apache.org/下载httpd web服务器，由于我的虚拟机上之前安装过，我先yum remove httpd进行卸载，然后重新安装。我采用的是源码安装，先进行./configure --prefix=/usr/local/apahce --enable-so ，提示以下错误：
configure: error: APR not found. Please read the documentation.
解决办法
wget http://apache.freelamp.com/apr/apr-1.4.2.tar.gz 下载apr
./configure –prefix=/usr/local/apr
make
make install
wget http://apache.freelamp.com/apr/apr-util-1.3.10.tar.gz
./configure –prefix=/usr/local/web/apr-util –with-apr=/usr/local/apr
make
make install
3 ../configure仍提示APR-util not found，增加--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util后出现
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
#./configure –help | grep pcre
--with-pcre=PATH Use external PCRE library
下载：http://sourceforge.net/projects/pcre
下载地址二：http://ftp.exim.llorien.org/pcre/
#unzip -o pcre-8.10.zip
#cd pcre-8.10
#./configure --prefix=/usr/local/pcre
#make
#make install
最后安装apahce：
./configure --prefix=/usr/local/apache --enable-rewrite --enable-so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre
make
make install
