1.官网下载apache2.4包，解压

2.由于2.4需要额外安装apr，所以需要编译安装 apr  

否则会报错   checking for APR... no

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

3.下载所需软件包：

1. wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz  
2. wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz  
3. wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip   

4.编译安装：

1. yum remove apr-util-devel apr apr-util-mysql apr-docs apr-devel apr-util apr-util-docs 

具体步骤如下:

  a:解决apr not found问题>>>>>>

1. [root@xt test]# tar -zxf apr-1.4.5.tar.gz  
2. [root@xt test]# cd  apr-1.4.5  
3. [root@xt apr-1.4.5]# ./configure --prefix=/usr/local/apr  
4. [root@xt apr-1.4.5]# sudo make && sudo make install  
5.  

  b:解决APR-util not found问题>>>>

1. [root@xt test]# tar -zxf apr-util-1.3.12.tar.gz  
2. [root@xt test]# cd apr-util-1.3.12  
3. [root@xt apr-util-1.3.12]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config  
4. [root@xt apr-util-1.3.12]# sudo make && sudo make install 

  c:解决pcre问题>>>>>>>>>

1. [root@xt test]# unzip -o pcre-8.10.zip  
2. [root@xt test]# cd pcre-8.10  
3. [root@xt pcre-8.10]# ./configure --prefix=/usr/local/pcre  
4. [root@xt pcre-8.10]# sudo make && sudo make install 

4.最后编译Apache时加上：

进入apache下载目录

./configure --prefix=/usr/local/myapache --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util  --with-pcre=/usr/local/pcre

成功编译完成~

5.启动apache

sudo /usr/local/myapache/bin/apachectl -f /usr/local/myapache/conf/httpd.conf 

成功提示 httpd (pid 21768) already running

停止apache

sudo /usr/local/myapache/bin/apachectl stop

6.如果启动报错

AH00558: httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.1.1. Set the ‘ServerName‘ directive globally to suppress this message
(13)Permission denied: AH00072: make_sock: could not bind to address [::]:80
(13)Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs

则需要在 apache到conf目录下修改httpd.conf  加入 ServerName localhost:80
