构建一个分布的LAMP系统

 系统鸟瞰如下图：

  整个系统位于LAN:192.168.31.0/24之中，两台httpd服务器通过DNS系统共同分担客户请求，他们使用相同的配置，其DocumentRoot相同且均位于局域网内的另一台NFS服务器上，网页php脚本通过php-fcgi的方式解释执行，必要时，php将会访问局域网中的数据库服务器为网站提供数据库服务。 

  http服务器与php、Xcache将采用源码方式安装，NFS使用RPM方式安装，mysql使用官方发布的X86-64二进制包方式安装，事先，我们已经在admin主机192.168.31.98上架起了一个公共的http服务器，并将系统安装所需各压缩文件均放置在http://192.168.31.98/tarball/之下。

  安装、配置两台HTTP服务器：

  安装脚本如下：

install_http.sh

 1 declare tempDir=`mktemp -d` 
 2 declare aprDir=/usr/local/apr
 3 declare aprutilDir=/usr/local/apr-util
 4 declare apacheDir=/usr/local/apache249

56 # mamange the /etc/init.d/httpd249 scripts   
57 # chkconfig --add httpd249

  分别在192.168.31.2与192.168.31.3上用bash解释执行install_http.sh脚本。然后将httpd添加入系统服务。

  1 # This is the main Apache HTTP server configuration file.  It contains the
  2 # configuration directives that give the server its instructions.
  3 # See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
  4 # In particular, see 
  5 # <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
  6 # for a discussion of each configuration directive.
  7 #
  8 # Do NOT simply read the instructions in here without understanding
  9 # what they do.  They're here only as hints or reminders.  If you are unsure
 10 # consult the online docs. You have been warned.  
 11 #
 12 # Configuration and logfile names: If the filenames you specify for many
 13 # of the server's control files begin with "/" (or "drive:/" for Win32), the
 14 # server will use that explicit path.  If the filenames do *not* begin
 15 # with "/", the value of ServerRoot is prepended -- so "logs/access_log"
 16 # with ServerRoot set to "/usr/local/apache2" will be interpreted by the
 17 # server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 
 18 # will be interpreted as '/logs/access_log'.
 19 
 20 #
 21 # ServerRoot: The top of the directory tree under which the server's
 22 # configuration, error, and log files are kept.
 23 #
 24 # Do not add a slash at the end of the directory path.  If you point
 25 # ServerRoot at a non-local disk, be sure to specify a local disk on the
 26 # Mutex directive, if file-based mutexes are used.  If you wish to share the
 27 # same ServerRoot for multiple httpd daemons, you will need to change at
 28 # least PidFile.
 29 #
 30 ServerRoot "/usr/local/apache249"
 31 PidFile /var/run/httpd/httpd.pid
 32 #
 33 # Mutex: Allows you to set the mutex mechanism and mutex file directory
 34 # for individual mutexes, or change the global defaults
 35 #
 36 # Uncomment and change the directory if mutexes are file-based and the default
 37 # mutex file directory is not on a local disk or is not appropriate for some
 38 # other reason.
 39 #
 40 # Mutex default:logs
 41 
 42 #
 43 # Listen: Allows you to bind Apache to specific IP addresses and/or
 44 # ports, instead of the default. See also the <VirtualHost>
 45 # directive.
 46 #
 47 # Change this to Listen on specific IP addresses as shown below to
