configure: error: APR not found.  Please read the documentation.

```

应该是缺少依赖包

这是ubuntu上的做法  http://stackoverflow.com/questions/13967114/configure-error-apr-not-found-please-read-the-documentation

我这里是centos啊。

这个回答比较靠谱，还是要去阅读官方的安装文档

就是需要安装arp相关的包，这可能是apache2.4 才会有的问题。

download the latest versions of both APR and APR-Util from Apache APR, unpack them into ./srclib/apr and ./srclib/apr-util (be sure the domain names do not have version numbers; for example, the APR distribution must be under ./srclib/apr/)

具体做法：

直接使用yum安装（可能有版本问题）

# yum install apr apr-util apr-devel

结果还是不行 apr的版本小于1.4了。

老老实实手动安装 root用户。

wget  http://mirrors.axint.net/apache//apr/apr-1.4.6.tar.gz

tar -xvzf apr-1.4.6.tar.gz

cd apr-1.4.6

./configure 

make && make install

wget  http://mirrors.axint.net/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 --with-apr=/usr/local/apr

make && make install

安装之后还缺少pcre包

yum install pcre pcre-devel

这些都安装好以后，然后继续安装apahce 就行了
