近些日子，由于手里的项目涉及到了WEB基础环境，于是乎想着尽量简化基础环境的编译过程，因为编译实在是一件漫长的事情，而且其中就说不定会有编译报错，而解决这一问题的同时将花费一定时间，会给工作进度带来无形的压力。其实WEB基础环境的配置不复杂，之前笔者也部署过许许多多次，也看过很多名家的有关图书与文章。见过许多经典的SHELL脚本，一键安装、优化WEB配置，本次所写内容也是基于自己的项目、柔和了别人的脚本，而得来，还望看官不要见笑。

      首先说，网上的很多LA/NMP的一键安装脚本，多数都是直接下载并源码编译。我觉得编译速度、编译出错是我更改脚本直接原因。而我现在做的是只编译一台服务器的WEB环境，将此环境归档打包至其余服务器上。这样我只要保证1台服务器的可用，其余服务器也会一样可用。现给出脚本与其中细节遇到的问题处理方法。

以上脚本是AMP的快速平移过程。笔者已测试并在生产环境中运行。其中apache2.4.3,mysql5.5.28，php5.4.9。源码编译过程这里就不详细书写了，编译很简单3板斧嘛，configure  && make && make install ,过程中笔者在编译apache时出现，dirxxx.so找不到,解决办法为将apache 的apr,apr-util扩展编译好后，复制到apache的slib目录中即可。另：编译时的安装目录，即--prefix 选项，在平移后要保持绝对路径一致。因为编译已经写死，大家可以在编译前按照给自公司运维规范，把以上脚本改好，只需改动路径即可。另：低版本amp编译过程中，会遇到php的动态库问题，导致apache无法启动，这与高版本的apache、php不太一样，需要把缺少的so文件复制到另一server的/usr/lib  /usr/lib64中。本脚不做详细解释，如果您也是一名运维人员或是shell爱好着，相信以上的脚本您可以看懂，还能帮我提出不少宝贵意见。如果有朋友用了以上的脚本出现问题，或是平移途中出现问题，可以与笔者联系，笔者将尽力帮您分析解决您的问题。 NMP的脚本与AMP类似，无非是多加个php-cgi或是php-fpm的启动项与判断条件，如有需要也可联系笔者，笔者愿与您一起分享。
