到http://httpd.apache.org/下载以源码方式安装，我下载的版本是Apache httpd 2.4.3

解压：[root@localhost apache]# tar -jxvf httpd-2.4.3.tar.bz2

配置环境：

[root@localhost httpd-2.4.3]# ./configure --prefix=/usr/local/apache2 --enable-so --enable-mods-shared=all --enable-modules=most

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

解决：
缺少Apr，下载http://projects.apache.org/indexes/quick.html

解压：[root@localhost apache]# tar zxvf apr-1.4.6.tar.gz

配置环境：

[root@localhost apr-1.4.6]# ./configure --prefix=/usr/local/apr/

编译和安装：

[root@localhost apr-1.4.6]#make

[root@localhost apr-1.4.6]#make install

编译安装完成apr之后，继续编译apache,又有如下的提示configure: error: APR-util not found. Please read the documentation

解决：

缺少APR-util，http://apr.apache.org/下载

解压: [root@localhost apache]# tar zxvf apr-util-1.4.1.tar.gz

配置环境:

在 [root@localhost apr-util-1.4.1]./configure --prefix=/usr/local/apr-util -with- apr=/usr/local/apr/bin/apr-1-config时，提示configure: error: APR could not be located. Please use the --with-apr option，这是路径的问题（这个问题困扰我好久了,在这里找到了说明http://apache.jz123.cn/install.html），应该用下面的命令[root@localhost apr-util-1.4.1]./configure --with-apr=/usr/local/

继续编译Apache，晕啊，仍没有成功，提示如下configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

解决：

下载prce,网址http://sourceforge.net/projects/pcre/

解压：unzip pcre-8.31.zip

配置环境：

[root@localhost pcre-8.31]#./configure --prefix=/usr/local/

编译和安装：

[root@localhost pcre-8.31]#make

[root@localhost pcre-8.31]#make install

再次编译Apache，皇天不负有心人啊，终于通过了!此时运行httpd(service httpd start),在浏览器上输入127：0：0：1，就能看到下面的了
