ICE的通讯结构：
ICE有分为提供服务的一方Server和寻求服务的一方Client，两台机子上都需要安装ICE组件，他们的通信结构如上图
Client端应该事先知道Server端能提供的服务是什么，有什么格式？这就是图中的Proxy Code，在Proxy Code中定义好了类和接口。Server端中接口定义的就是
Skeleton，具体实现接口的是Server Application，Server Application可以是C++,java,C#等写的，但是ICE不提供PHP写Server端。
ICE安装方式：
1.redhat5:(ice3.4.2) yum源安装
????????01.download: cd /etc/yum.repos.d/ wget https://zeroc.com/download/Ice/3.4/rhel5/zeroc-ice.repo
????????????????如果无法下载以上地址，可能使被墙了，试试：wget http://www.zeroc.com/download/Ice/3.4/rhel5/zeroc-ice.repo
????????????????zeroc-ice.repo的内容为:
????????????????????????????[zeroc-ice]
????????????????????????????name=Ice 3.4 for RHEL $releasever - $basearch
????????????????????????????baseurl=http://www.zeroc.com/download/Ice/3.4/rhel$releasever/$basearch
????????????????????????????enabled=1
????????????????????????????gpgcheck=1
????????????????????????????gpgkey=http://www.zeroc.com/download/RPM-GPG-KEY-zeroc-release
????????02.编辑zeroc-ice.repo：
????????????????????????????[zeroc-ice]
????????????????????????????name=Ice 3.4 for RHEL $releasever - $basearch
????????????????????????????baseurl=http://www.zeroc.com/download/Ice/3.4/rhel5/$basearch
????????????????????????????enabled=1
????????????????????????????gpgcheck=1
????????????????????????????gpgkey=http://www.zeroc.com/download/RPM-GPG-KEY-zeroc-release
????????03.查看 yum list ice* db46* mcpp-devel 或 yum list ice* db48* mcpp-devel（官方）
????????04.安装 yum install ice* db46* mcpp-devel 或 yum list ice* db48* mcpp-devel（官方）
????????05.emacs /etc/php.d/ice.ini 内容：extension=IcePHP.so
????????06.修改php.ini extension=IcePHP.so 并把IcePHP.so复制到extentsion_dir中
???????? 注意：这种方法的IcePHP.so module是官方编译的，只能适合官方指定的php版本：这里是php5.1.6
?
2.redhat5:(ice3.4.2) 编译安装64位（注意我的是64位操作系统，32位安装没有什么特别的地方）
????附上官方安装说明：
This source distribution only supports building Ice for PHP as a dynamic PHP extension; the product of the build is a shared library
that you must configure PHP to load. Follow the steps below to build Ice for PHP:
1. Change to Ice for PHP source subdirectory.
> cd Ice-3.4.2/php
?
2. Edit config/Make.rules and review the build settings. For example, you may want to enable OPTIMIZE. If your PHP installation resides
???????????????????? in a non-standard location, modify the PHP_HOME setting to contain the installation directory. If you are using PHP 5.3 or later and
????????????????????wish to use PHP namespaces, set USE_NAMESPACES=yes.
?
3. If you have not built Ice for C++ from the cpp subdirectory, then set the ICE_HOME environment variable to the directory containing
???????????????????? your Ice installation. For example, if Ice is installed in /opt/Ice-3.4.2, set ICE_HOME as follows: $ export ICE_HOME=/opt/Ice-3.4.2
If you installed Ice using RPMs, set ICE_HOME as shown below:
$ export ICE_HOME=/usr
3. Run make.
????说明：如果按照官方来安装是不可能安装成功的，从安装步骤编号1233就可以看出官方安装说明写得有多草率！
我的安装记录：
下载源码安装包Ice-3.4.2.tar.gz和第三方依赖包ThirdParty-Sources-3.4.2.tar.gz（官网有下载连接，这里就不贴了，一定要求去官网下载）
????先解压ThirdParty-Sources-3.4.2.tar.gz ： tar –xvf ThirdParty-Sources-3.4.2.tar.gz
????Cd ThirdParty-Sources-3.4.2
????????安装 mcpp-2.7.2:
????????tar -xvf mcpp-2.7.2.tar.gz
????????cd mcpp-2.7.2
????????./configure --prefix=/usr/local/ICE-3.4.2/mcpp-2.7.2/ CFLAGS=-fPIC --enable-mcpplib --disable-shared
????????make
????????make install
????????...On 64-bit platforms, after installation it is necessary to rename the
library installation directory from $(prefix)/lib to $(prefix>/lib64.（这句话是说把安装的mcpp目录中的lib目录名改成lib64，32位无需改动）
?
????????安装Berkeley DB:
????????tar -xvf db-4.8.30.NC.tar.gz
????????cd db-4.8.30.NC/build_unix/
???????? ../dist/configure --prefix=/usr/local/ICE-3.4.2/BerkeleyDB.4.6/ --enable-cxx
????????make
????????make install
????????...On 64-bit platforms, after installation it is necessary to rename the
library installation directory from $(prefix)/lib to $(prefix>/lib64.（这里也要把lib—> lib64）
?
????????安装bzip2:
????????cd ../../
????????tar -xvf bzip2-1.0.6.tar.gz
????????cd bzip2-1.0.6
????????//32位机器：Makefile PREFIX=/usr/local/ICE-3.4.2/bzip2-1.06
????????//64位机器：make -f Makefile-libbz2_so
????????make
????????make install PREFIX=/usr/local/ICE-3.4.2/bzip2-1.06
????????...On 64-bit platforms, after installation it is necessary to rename the
library installation directory from $(prefix)/lib to $(prefix>/lib64. （这里也要把lib—> lib64）
?
????????安装expat:
????????cd ..
????????tar -xvf expat-2.0.1.tar.gz
????????cd expat-2.0.1
????????./configure --prefix=/usr/local/ICE-3.4.2/expat-2.0.1/
????????make
????????make install
????????...On 64-bit platforms, after installation it is necessary to rename the
library installation directory from $(prefix)/lib to $(prefix>/lib64. （这里也要把lib—> lib64）
?
????????安装oppenssl:
????????cd ..
????????tar -xvf openssl-0.9.8r.tar.gz
????????cd openssl-0.9.8r
????????./config --prefix=/usr/local/ICE-3.4.2/openssl
????????make
????????make install
????????//好像不需要改成lib64，（这里我没改lib64就安装成功了，注意每次重新安装的时候记得先清理一下：make clean）
????????redhat5.7在默认情况下会在usr/lib中搜索*.so，但在64位系统中*.so在usr/lib64和usr/local/lib64中，故要将包含对应xx.so文件拷贝到usr/lib中，更简单的做法是加入到LD_LIBRARY_PATH变量中，如下面/etc/profile的修改
?
????没有报错安装完成Ice3.4.2
?
????修改/etc/profile:在尾部加上
????????export PHPPATH=/wdxy/ICE-3.4.2/Ice-3.4.2/php/:
????????export ICE_HOME=/wdxy/ICE-3.4.2/Ice-3.4.2
????????export PATH=$PATH:$ICE_HOME/bin
????????export LD_LIBRARY_PATH=$ICE_HOME/lib64:/usr/local/ICE-3.4.2/expat-2.0.1/lib64:$LD_LIBRARY_PATH
????????export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC ICE_HOME
?
????编译生成动态库IcePHP.so
????????cd ../php
????????emacs config/Make.rule.php四处：
????????????prefix ?= /wdxy/ICE-3.3.0/Ice-$(VERSION)
????????????embedded_runpath_prefix ?= /wdxy/ICE-3.3.0/Ice-$(VERSION_MAJOR).$(VERSION_MINOR)
????????????PHP_HOME ?= /home/ap/php5.2 //注意是PHP_HOME目录，不是bin/php 或php执行文件的路径（我在这里坑了半天，报unkown php version ） 后面会附上php5.2.17 php-fpm的安装
????????????LP64 := yes
????????make
????????make install
????????将会在/wdxy/ICE-3.3.0/Ice-$(VERSION)目录下生成php文件夹，内有IcePHP.so文件，拷贝到对应php的extension_dir下
????????????php -i | grep extension_dir 查看extension_dir
?
????修改php.ini文件：
????????[Ice]
????????include_path = "/home/ap/php5.2/lib/php:/wdxy/ICE-3.4.2/Ice-3.4.2/php"
????????extension=IcePHP.so
?
????php -m 可以看到ice模块的存在表示安装成功
????Icephp安装配置完成
