访问官网，下载安装包

添加编译依赖
今日编译apache时出错：
#./configure --prefix……检查编辑环境时出现：
checking for APR... no
configure: error: APR not found . Please read the documentation
解决办法：
1.下载所需软件包：
wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz
wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz
wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip
2.编译安装：
yum remove apr-util-devel apr apr-util-mysql apr-docs apr-devel apr-util apr-util-docs
yum install gcc-c++ libstdc++-devel
yum install gcc
具体步骤如下:
a:解决apr not found问题>>>>>>
[root@xt test]# tar -zxf apr-1.4.5.tar.gz
[root@xt test]# cd apr-1.4.5
[root@xt apr-1.4.5]# ./configure--prefix=/usr/local/apr
[root@xt apr-1.4.5]# make && make install
b:解决APR-util not found问题>>>>
[root@xt test]# tar -zxf apr-util-1.3.12.tar.gz
[root@xt test]# cd apr-util-1.3.12
[root@xt apr-util-1.3.12]# ./configure--prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config
[root@xt apr-util-1.3.12]# make && make install
c:解决pcre问题>>>>>>>>>
[root@xt test]#unzip -o pcre-8.10.zip
[root@xt test]#cd pcre-8.10
[root@xt pcre-8.10]#./configure--prefix=/usr/local/pcre
[root@xt pcre-8.10]#make && make install
注意：这里如果./configure不成功，可以添加参数
./configure --prefix=/usr/local/pcre --disable-shared --with-pic
3.最后编译Apache时加上：
./configure --prefix=/usr/local/httpd --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre
