1、安装LNMP 所需的安装包有点多，要耐心.......,下载的链接张老师的博客上有：
http://sysoev.ru/nginx/nginx-0.8.46.tar.gz
#nginx主程序包
http://www.php.net/get/php-5.2.14.tar.gz/from/this/mirror
#PHP主程序包
http://php-fpm.org/downloads/php-5.2.14-fpm-0.5.14.diff.gz
#PHP的FastCGI进程管理补丁包

#mysql主程序包
http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
libiconv库是一个基于GNU协议的开源库，主要是解决多语言编码处理转换等应用问题;
由于历史原因，国际化的文字常常由于语言或者国家的原因使用不同的编码。随着互联网时代的到来，通过互联网进行文字交流也逐渐增多：浏览外国的网站，这个时候字符编码的转换变得尤为重要。这带来了一个问题，就是许多字符在某一种编码方式中没有。为了解决这种混乱，Unicode的编码方式被建立。 Unicode是一种超级编码包含了所有这些编码的字符集，因此一些新的文本格式像XML的默认编码方式就是Unicode.
但是很多老式的计算机还在使用当地的传统的字符编码方式。而一些程序，例如邮件程序和浏览器必须能在这些不同的用户编码之间作转换。其他的一些程序则内置支持Unicode，以顺利支持国际化的处理，但是仍然有在Unicode和其他的传统编码之间转换的需求。GNU的libiconv就是为这两种应用设计的编码转换库。libiconv库为需要做转换的应用提供了一个iconv()的函数，以实现一个字符编码到另一个字符编码的转换。

#安全线程加密库主程序包
http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.8.tar.gz?modtime=1194463373&big_mirror=0
#Mcrypt是一个功能强大的加密算法扩展库，它包括有22种算法
http://pecl.php.net/get/memcache-2.2.5.tgz
#memcache是一个高性能的分布式的内存对象缓存系统，通过在内存里维护一个统一的巨大的hash表，它能够用来存储各种格式的数据，包括图像、视频、文件以及数据库检索的结果等。Memcache是danga.com的一个项目，最早是为 LiveJournal 服务的，最初为了加速 LiveJournal 访问速度而开发的，后来被很多大型的网站采用。目前全世界不少人使用这个缓存项目来构建自己大负载的网站，来分担数据库的压力。起初作者编写它可能是为了提高动态网页应用，为了减轻数据库检索的压力，来做的这个缓存系统。它的缓存是一种分布式的，也就是可以允许不同主机上的多个用户同时访问这个缓存系统， 这种方法不仅解决了共享内存只能是单机的弊端，同时也解决了数据库检索的压力，最大的优点是提高了访问获取数据的速度！基于memcache作者对分布式 cache的理解和解决方案。 memcache完全可以用到其他地方 比如分布式数据库， 分布式计算等领域。
http://downloads.sourceforge.net/mhash/mhash-0.9.9.9.tar.gz?modtime=1175740843&big_mirror=0
#Mhash扩展库,Mhash扩展库支持12种混编算法

#正则表达式扩展主程序包
http://bart.eaccelerator.net/source/0.9.6.1/eaccelerator-0.9.6.1.tar.bz2
#eAccelerator是一个自由开放源码php加速器，优化和动态内容缓存，提高了php脚本的缓存性能，使得PHP脚本在编译的状态下，对服务器的开销几乎完全消除。 它还有对脚本起优化作用，以加快其执行效率。使您的PHP程序代码执效率能提高1-10倍；
http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz
#PDO 是 PHP 数据对象的缩写， 是一种访问数据库的更便捷、安全的途径。通过该方式，数据库开发者可以更方便地写出移植性较高的代码。PDO 并不是类似于 PearDB 的数据库抽象层，而 更像一种采用了统一 API (应用编程接口)的数据访问层。
如何启用PDO?要启用 PDO 配置，须打开 pdo 、pdo_sqlite、pdo_mysql等所的扩展模块
http://blog.s135.com/soft/linux/nginx_php/imagick/ImageMagick.tar.gz
#是一个免费的创建、编辑、合成图片的软件。它可以读取、转换、写入多种格式的图片。图片切割、颜色替换、各种效果的应用，图片的旋转、组合，文本，直线，多边形，椭圆，曲线，附加到图片伸展旋转。ImageMagick是免费软件：全部源码开放，可以自由使用，复制，修改，发布。它遵守GPL许可协议。它可以运行于大多数的操作系统。ImageMagick的大多数功能的使用都来源于命令行工具。通常来说，它可以支持以下程序语言： Perl, C, C++, Python, PHP, Ruby, Java
http://pecl.php.net/get/imagick-2.3.0.tgz
#一般用php处理图片都是使用GD库或者GD2的函数库，一般编译php环境都会搭上GD库，大多数开源程序也是用GD来处理图片的，但是它只能现实诸如调整大小、增加水印等基础功能，要想用GD来做复杂图形是非常困难的。
基于命令行的图像处理软件ImageMagick，能实现非常丰富的功能。如果服务器上安装了ImageMagick，php脚本可以使用 shell命令来完成，也可以用php的原生函数库Imagick或者MagickWandForPHP函数来调用ImageMagick软件来实现。
因为Linux系统下PHP往往没有执行shell的权限，直接用shell来操作ImageMagick不太可能，综合考虑，Imagick函数库连接到ImageMagick软件比较好，而且是面向对象方式的。
2、安装php（fastcgi模式）
（1）、安装php所需的支持库
[root@mgmserver tar_packet]# tar -zxvf libiconv-1.13.1.tar.gz -C ../install_packet/
[root@mgmserver libiconv-1.13.1]# ./configure --prefix=/usr/local
[root@mgmserver libiconv-1.13.1]# make
[root@mgmserver libiconv-1.13.1]# make install
[root@mgmserver tar_packet]# tar -zxvf libmcrypt-2.5.8.tar.gz -C ../install_packet/
[root@mgmserver libmcrypt-2.5.8]# ./configure
[root@mgmserver libmcrypt-2.5.8]# make
[root@mgmserver libmcrypt-2.5.8]# make install
[root@mgmserver libltdl]# /sbin/ldconfig （配置动态连接器(ld)运行时邦定）
[root@mgmserver libltdl]# cd libltdl/
[root@mgmserver libltdl]# ./configure --enable-ltdl-install
[root@mgmserver libltdl]# make
[root@mgmserver libltdl]# make install
[root@mgmserver tar_packet]# tar -zxvf mhash-0.9.9.9.tar.gz -C ../install_packet/
[root@mgmserver install_packet]# cd mhash-0.9.9.9/
[root@mgmserver mhash-0.9.9.9]# ./configure
[root@mgmserver mhash-0.9.9.9]# make
[root@mgmserver mhash-0.9.9.9]# make install
[root@server5 mhash-0.9.9.9]# ln -s /usr/local/lib/* /usr/lib
(这一步不用做了 ，做完成上面步骤后/usr/lib下面已经存在了)
[root@localhost install_packet]# ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
[root@localhost install_packet]# ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
[root@localhost install_packet]# ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
[root@localhost install_packet]# ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
[root@localhost install_packet]# ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
[root@localhost install_packet]# ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
[root@localhost install_packet]# ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so

[root@localhost install_packet]# ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
[root@localhost install_packet]# ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
[root@mgmserver tar_packet]# tar -zxvf mcrypt-2.6.8.tar.gz -C ../install_packet/
[root@mgmserver mcrypt-2.6.8]# /sbin/ldconfig
[root@mgmserver mcrypt-2.6.8]# ./configure
[root@mgmserver mcrypt-2.6.8]# make
[root@mgmserver mcrypt-2.6.8]# make install
(2)、安装mysql
[root@mgmserver tar_packet]# groupadd mysql
[root@mgmserver tar_packet]# useradd -g mysql mysql
[root@mgmserver tar_packet]#tar -zxvf mysql-5.5.3-m3.tar.gz -C ../install_packet/
[root@mgmserver mysql-5.5.3-m3]# ./configure --prefix=/usr/local/mysql --enable-assembler --with-charset=utf8 --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=innobase --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock
[root@mgmserver mysql-5.5.3-m3]# make
[root@mgmserver mysql-5.5.3-m3]# make install
[root@mgmserver mysql-5.5.3-m3]# cp support-files/my-large.cnf /etc/my.cnf
[root@mgmserver mysql]# pwd
/usr/local/mysql
[root@mgmserver mysql]# bin/mysql_install_db --user=mysql
Installing MySQL system tables...
100903 13:30:41 [ERROR] /usr/local/mysql/libexec/mysqld: unknown variable 'thread_concurren cy=8'
100903 13:30:41 [ERROR] Aborting
100903 13:30:41 [Note] /usr/local/mysql/libexec/mysqld: Shutdown complete
.......
mysql 初始化报错，发现网上有哥们已经解决了这个问题，实在是强大，原因是my.cnf中有一行：
thread_concurrency = 8
thread_concurrency这个变量，意思是并发的线程数，并且根据给的解释是该参数取值为服务器逻辑CPU数量×2，而如果每颗物理CPU又支持H.T超线程，所以实际取值为4 × 2 ＝ 8。而我这个机器是ADM闪龙3000 单核的CPU，并不符合它的要求，所以它提示“unknown variable ‘thread_concurrency=8′”是个未知变量。对my.cnf做一些修改，把’thread_concurrency=8′注释掉
重新初始化OK
[root@mgmserver mysql]# bin/mysql_install_db --user=mysql
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
...........
[root@localhost mysql]# chown -R root .
[root@localhost mysql]# chown -R mysql var
[root@localhost mysql]# chgrp -R mysql .
[root@mgmserver mysql]# cp share/mysql/mysql.server /etc/init.d/mysqld
[root@mgmserver mysql]# chkconfig --add mysqld
[root@mgmserver mysql]# cd /etc/init.d/
[root@mgmserver init.d]# chmod +x mysqld
[root@mgmserver init.d]# chkconfig --list mysqld

(3)、编译安装pHP (fastcgi模式)
[root@mgmserver tar_packet]# tar -zxvf php-5.2.14.tar.gz -C ../install_packet/
[root@mgmserver php-5.2.14]# pwd
/home/install_packet/php-5.2.14
[root@localhost install_packet]# gzip -cd php-5.2.14-fpm-0.5.14.diff.gz |patch -d php-5.2.14 -p1
[root@mgmserver php-5.2.14]# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash -enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap
[root@mgmserver php-5.2.14]# make ZEND_EXTRA_LIBS='-liconv'
[root@mgmserver php-5.2.14]# make install
[root@mgmserver php-5.2.14]# cp php.ini-dist /usr/local/php/etc/php.ini
(4)、安装PHP扩展
[root@mgmserver tar_packet]# tar -zxvf memcache-2.2.5.tgz -C ../install_packet/
[root@mgmserver memcache-2.2.5]# /usr/local/php/bin/phpize
[root@mgmserver memcache-2.2.5]# ./configure --with-php-config=/usr/local/php/bin/php-config
[root@mgmserver memcache-2.2.5]# make
[root@mgmserver memcache-2.2.5]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
[root@mgmserver tar_packet]# tar -jxvf eaccelerator-0.9.6.1.tar.bz2 -C ../install_packet/
[root@mgmserver install_packet]# cd eaccelerator-0.9.6.1/
[root@mgmserver eaccelerator-0.9.6.1]# /usr/local/php/bin/phpize
[root@mgmserver eaccelerator-0.9.6.1]# ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
[root@mgmserver eaccelerator-0.9.6.1]# make
[root@mgmserver eaccelerator-0.9.6.1]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
[root@mgmserver tar_packet]# tar -zxvf PDO_MYSQL-1.0.2.tgz -C ../install_packet/
[root@mgmserver install_packet]# cd PDO_MYSQL-1.0.2/
[root@mgmserver PDO_MYSQL-1.0.2]# /usr/local/php/bin/phpize
[root@mgmserver PDO_MYSQL-1.0.2]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-

[root@mgmserver imagick-2.3.0]# make
[root@mgmserver imagick-2.3.0]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
(5)、修改php.ini文件
找到491行的extension_dir = "./"
修改为 extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613" 指定模块所在的位置；
在这行后面加上
493 extension = "imagick.so"
494 extension = " memcache.so"
495 extension = "pdo_mysql.so"
在 101行处
修改 output_buffering = Off为 output_buffering = On
把523 处的注释去掉， cgi.fix_pathinfo=0 防止nginx文件类型错误解析漏洞
6、配置php加速eaccelerator
创建缓存文件夹;
[root@mgmserver local]# mkdir eaccelerator_cache
在php.ini配置文件末尾加上如下：
1290 [eaccelerator]
1291 extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so
1292 eaccelerator.shm_size="32"
1293 eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
1294 eaccelerator.enable="1"
1295 eaccelerator.optimizer="1"
1296 eaccelerator.check_mtime="1"
1297 eaccelerator.debug="0"
1298 eaccelerator.filter=""
1299 eaccelerator.shm_max="0"
1300 eaccelerator.shm_ttl="3600"
1301 eaccelerator.shm_prune_period="360"
1302 eaccelerator.shm_only="0"
1303 eaccelerator.compress="1"
1304 eaccelerator.compress_level="9"
（7）、悲剧了，空余的机器被拿去用了，只好换个机器，创建www 用户和组，及两个虚拟主机域名目录www.nginx.com与web.nginx.com
[root@mgmserver ~]# groupadd www
[root@mgmserver ~]# useradd -g www www
[root@nginx ~]# mkdir -p /web/htdocs/www.nginx.com
[root@nginx ~]# chown -R www:www /web/htdocs/www.nginx.com
[root@nginx ~]# mkdir -p /web/htdocs/web.nginx.com
[root@nginx ~]# chown -R www:www /web/htdocs/web.nginx.com/
8、修改php-fpm配置文件，黄色标记的是修改值

（9）、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为64
把配置文件的63行和66行修改如下：
62 Unix user of processes
63 <value name="user">www</value>
64
65 Unix group of processes
66 <value name="group">www</value>
切记要把63行和66行的注释符号去掉不然在启动时会出错的！

3、安装nginx
(1)、安装nginx及所需要的pcre库
[root@nginx pcre-8.10]# ./configure
[root@nginx pcre-8.10]# make
[root@nginx pcre-8.10]# make install
[root@nginx install_packet]# cd nginx-0.8.48/
[root@nginx nginx-0.8.48]# ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
[root@nginx nginx-0.8.48]#make
[root@nginx nginx-0.8.48]#make install
（2）、创建nginx的日志文件
[root@nginx /]# mkdir -p web/nginxlogs
[root@nginx /]# chmod +w web/nginxlogs/
[root@nginx /]# chown -R www:www web/nginxlogs/
（3）、修改nginx的配置文件如下：
1
2 user www www;
3 worker_processes 1;
4 error_log /web/nginxlogs/error.log crit;
5 pid /usr/local/nginx/nginx.pid;
6 worker_rlimit_nofile 65535;
7 events {
8 use epoll;
9 worker_connections 1024;
10 }
11
12
13 http {
14 include mime.types;
15 default_type application/octet-stream;
16
17 server_names_hash_bucket_size 128;
18 client_header_buffer_size 32k;
19 large_client_header_buffers 4 32k;
20 client_max_body_size 8m;
21
22
23 sendfile on;
24 tcp_nopush on;
25
26 #keepalive_timeout 0;
27 keepalive_timeout 60;
28 tcp_nodelay on;
29
30 fastcgi_connect_timeout 300;
31 fastcgi_send_timeout 300;
32 fastcgi_read_timeout 300;
33 fastcgi_buffer_size 64k;
34 fastcgi_buffers 4 64k;
35 fastcgi_busy_buffers_size 128k;
36 fastcgi_temp_file_write_size 128k;
37
38 gzip on;
39 gzip_min_length 1k;
40 gzip_buffers 4 16k;
41 gzip_http_version 1.0;
42 gzip_comp_level 2;
43 gzip_types text/plain application/x-javascript text/css application/xml;
44 gzip_vary on;
45
46 server {
47 listen 80;
48 server_name www.nginx.com;
49 root /web/htdocs/www.nginx.com;
50 index index.html index.htm index.php;
51
52 location ~.*\.(php|php5)?$ {
53 fastcgi_pass 127.0.0.1:9000;
54 fastcgi_index index.php;
55 include fastcgi.conf;
56 }
57
58 location ~.*\.(gif|jpg|jpeg|png|bmp|swf)$
59 {
60 expires 30d;
61 }
62 location ~.*\.(js|css)$
63 {
64 expires 1h;
65 }
66 log_format wwwaccess '$remote_addr - $remote_user [$time_local] "$request" '
67 '$status $body_bytes_sent "$http_referer" '
68 '"$http_user_agent" $http_x_forwarded_for';
69 access_log /web/nginxlogs/wwwaccess.log wwwaccess;
70 }
71
72
73 server {
74 listen 80;
75 server_name web.nginx.com;
76 root /web/htdocs/web.nginx.com;
77 index index.html index.htm index.php;
78 location ~.*\.(php|php5)?$
79 {
80 fastcgi_pass 127.0.0.1:9000;
81 fastcgi_index index.php;
82 include fastcgi.conf;
83 }
84 log_format webaccess '$remote_addr - $remote_user [$time_local] "$request"'
85 '$status $body_bytes_sent "$http_referer"'
86 '"$http_user_agent" $http_x_forwarded_for';
87 access_log /web/nginxlogs/webaccess.log webaccess;
88 }
89 }
（4）、保持conf/下fastcgi.conf配置文件不变就可以了
（5）、启动nginx
[root@nginx nginx]#/usr/
[root@nginx nginx]# /usr/local/nginx/sbin/nginx
(6)、开机启动nginx 与php
[root@nginx nginxlogs]# vi /etc/rc.local
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx
(7)修改文件中先检查配置文件是否正确，然后在启动
[root@nginx nginxlogs]# /usr/local/nginx/sbin/nginx -t
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@nginx nginxlogs]# kill -HUP `cat /usr/local/nginx/nginx.pid`
或者
[root@nginx nginxlogs]# /usr/loca/nginx/sbin/nginx -s reload
4、测试
在www.nginx.com的文档目录中
[root@nginx www.nginx.com]# vi index.php/
<?php phpinfo(); ?>
类似的在web.nginx.com中新建一个index.php文件：
基本上算是完成了涨老师的实验配置
