CentOS 6.2 源码包安装apache2.4.3以及相关异常处理

一.准备环境
1.安装gcc
[root@localhost /]# yum install gcc gcc-c++

2.安装apr,apr-util
  下载apr-1.4.6.tar.gz与apr-util-1.5.1.tar.gz，
  地址：http://apr.apache.org
  上传至/usr/local，
  安装目录分别为/usr/local/apr 与/usr/local/apr-util
a.安装apr-1.4.6.tar.gz
  [root@localhost local]# mkdir -p apr
  [root@localhost local]# tar -zxf apr-1.4.6.tar.gz
  [root@localhost local]# cd apr-1.4.6
  [root@yahoo apr-1.4.6]# ./configure --prefix=/usr/local/apr
  [root@yahoo apr-1.4.6]# make
  [root@yahoo apr-1.4.6]# make install
b.安装apr-util-1.5.1.tar.gz
  [root@localhost local]# mkdir -p apr-util
  [root@localhost local]# tar -zxf apr-util-1.5.1.tar.gz
  [root@localhost local]# cd apr-util-1.5.1
  [root@yahoo apr-util-1.5.1]# ./configure --prefix=/usr/local/apr-util 
                                           --with-apr=/usr/local/apr/bin/apr-1-config
  [root@yahoo apr-util-1.5.1]# make
  [root@yahoo apr-util-1.5.1]# make install
3.安装pcre-8.20.tar.gz
  下载地址：http://sourceforge.net/projects/pcre/files/pcre/ ，
  上传至/usr/local，
  安装目录为/usr/local/pcre[root@localhost local]# mkdir -p pcre[root@localhost local]# tar -zxf pcre-8.20.tar.gz[root@localhost local]# cd pcre-8.20[root@yahoo pcre-8.20]# ./configure --prefix=/usr/local/pcre[root@yahoo pcre-8.20]# make[root@yahoo pcre-8.20]# make install
二.安装apache
1.下载httpd-2.4.3.tar.gz，
  地址是：http://httpd.apache.org/ ，
  上传至/usr/local，
  安装目录为/usr/local/apache2
2.安装
  [root@localhost local]# mkdir -p /usr/local/apache2
  [root@localhost local]# tar zxvf httpd-2.4.3.tar.gz
  [root@localhost local]# cd httpd-2.4.3
  [root@localhost httpd-2.4.3]# ./configure --prefix=/usr/local/apache2 
                                            --with-pcre=/usr/local/pcre 
                                            --with-apr=/usr/local/apr
                                            --with-apr-util=/usr/local/apr-util
  [root@localhost httpd-2.4.3]# make
  [root@localhost httpd-2.4.3]# make install
  用浏览器访问http:localhost，看到It works!，说明CentOS Apache安装成功了，恭喜您！
3.启动第一种方法
  [root@localhost apache2]# /usr/local/apache2/bin/apachectl start
  第二种方法
  [root@localhost apache2]#service httpd start
  第三种方法
  [root@localhost apache2]#/etc/init.d/httpd start 
  第三种方法：
  [root@localhost httpd-2.4.43]# sysytemctl start httpd

三.安装出现的问题.
1.configure: error: no acceptable cc found in $PATH
 解决办法：yum install gcc gcc-c++

2.configure: error: APR not found. Please read the documentation.
  解决方法：安装Apache的关联软件如上安装apr-1.4.6.tar.gz
3.configure: error: APR-util not found. Please read the documentation
  解决方法：安装apr-util如上安装apr-util-1.5.1.tar.gz
4.configure: error: APR version 1.3.0 or later is required
  主要是因为apr版本过低造成的，应该卸载相关旧版本
5. 启动时报错：AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message
  解救办法：绝对路径即可：/usr/local/apache2/bin/apachectl start
6.AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message98)Address already in use: AH00072: make_sock: could not bind to address [::]:80(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80no listening sockets available, shutting downAH00015: Unable to open logs
  解救办法：端口被占用：停止之前的服务或占用端口的服务，再次执行启动即可

四.重要配置文件目录/etc/httpd/conf/httpd.conf　　
  [root@localhost httpd-2.4.43]# sysytemctl stop httpd
  最主要的配置文件

  /usr/lib/httpd/modules:apache　　
  支持很多的模块，所以你想要使用的模块默认都放置在此目录/var/log/httpd　　　　　　　　
  apache默认的log/var/www/html　　　　
  cenos默认的首页所在目录
五.配置apache
  最后修改httpd.conf，
  使apache能使用php增加如下参数  
  AddType application/x-httpd-php .php 
  AddType application/x-httpd-php-source .phps  
  AddType image/x-icon .ico
  DirectoryIndex index.php index.html index.html.var
