编译安装LEMP

另外一个参考：http://blog.s135.com/nginx_php_v6/

虽然很多人建议使用一键安装包来安装WEB套件LEMP(又称LNMP)，但在我看来，既然大家买了VPS，就要有折腾的决心，否则，和普通的性能强点的虚拟主机又有何区别呢？所以，个人建议大家还是自己亲自折腾一下这个配置过程，一来可以学习Linux，二来下次碰到问题也不会手忙脚乱不知所措.

本教程使用的Linux环境为centos 6.0和Fedora 15,如果你使用其它的Linux发行版本，请确认你的登陆用户权限是否为root （对于root无法登陆的用户，在执行命令时候，请加上sudo）, 其次请确定你的安装软件的管理包是什么，比如CentOS/Fedora/Redhat使用的是yum,而ubuntu使用的是apt-get.

教程中使用的Nginx是最新的稳定版本1.0.8,Mysql使用5.1.58,PHP则是5.2.17，以及PHP-FPM的版本是php-5.2.17-fpm-0.5.14，以及用于加速PHP的eaccelerator-0.9.6.1

一.下面开始安装吧.首先建议用以下命令检查系统中是否有装过或者残留的php/mysql/apache等相关的服务，以免影响了安装.

用rpm命令来检查相关软件

rpm -qa|grep  httpd
rpm -e httpd
rpm -qa|grep mysql
rpm -e mysql
rpm -qa|grep php
rpm -e php

上面的命令中rpm -qa表示列出所有安装好的软件，grep则是过滤只列出有关键词httpd的.参数-e表示erase，也就是卸载的意思.

不过rpm卸载软件可能不能解决好软件依赖问题，所以再用yum remove卸载一次，参数-y表示不再询问你yes/no，直接执行.

yum -y remove httpd
yum -y remove php
yum -y remove mysql-server mysql
yum -y remove php-mysql

二. 接下来，安装一些需要的依赖库.

#这个命令非常长
#下面许多./configure命令也存在这种情况
#复制时注意下面滚动条，或者同时复制多行执行
yum -y install patch make gcc gcc-c++ gcc-g77 flex bison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel vim-minimal nano fonts-chinese gettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip

三.下载、编译、安装、配置过程

开始下载并安装需要的软件，对于国内的主机或者VPS建议使用国内镜像下载，比较著名的有sohu/163以及各大学的镜像，对于国外的VPS或者独立主机用户，选则相应国家的镜像下载速度会非常快，毕竟资本主义的网速比我们快.

因为我的主机为Linode的东京机房，所以我尽量使用日本的镜像，大家在官方网站下载时，对于有多个镜像供选择的官方下载，我会给你提供镜像选择链接，替换为你的下载链接即可.

首先建立一个目录用于下载安装的文件吧.

mkdir lemp
cd lemp/

接下来下载并解压需要的软件

1.编译依赖库autoconf、libiconv等

稍微解释一下这几步，一般在Linux中编译程序，都是configure/make/make install三步，configure的作用是检查系统环境并生成Makefile文件，因为每个系统环境参数可能有所不同.make则是编译并生成可执行文件,make install则是把生成的部署到系统里面.

到此为止，你已经安装好了LEMP，至于优化的文章，大家可以自行搜过吧，呵呵~

重要的根目录:

mysql: /usr/local/mysql

php: /usr/local/php

nginx: /usr/local/nginx

web: /home/wwwroot

如果要添加虚拟主机，则搜索nginx添加虚拟主机的一般用法即可。

本文参考了lnmp.org的一键安装包，实际上更多地是对其代码进行了解析，并改成更符合人工部署逻辑和代码阅读的习惯，十分感谢.其中去掉了zend_optimize组件，替代为eAccelerator，另外不建议关闭SELinux服务，这是redhat发行版的精华，也是安全保障所在。

另外我自己修改后的一个更符合更适合阅读的代码，你可以下载作为LEMP自动化部署套件使用，对于非基于redhat发行版，请自行参考修改.
