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

http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.3-m3.tar.gz/from/http://mysql.he.net/

#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。

http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz?modtime=1171868460&big_mirror=0

#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

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.10.tar.gz

#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

[[email protected] tar_packet]# tar -zxvf libiconv-1.13.1.tar.gz -C ../install_packet/
[[email protected] libiconv-1.13.1]# ./configure --prefix=/usr/local
[[email protected] libiconv-1.13.1]# make
[[email protected] libiconv-1.13.1]# make install

[[email protected] tar_packet]# tar -zxvf libmcrypt-2.5.8.tar.gz -C ../install_packet/

[[email protected] libmcrypt-2.5.8]# ./configure

[[email protected] libmcrypt-2.5.8]# make

[[email protected] libmcrypt-2.5.8]# make install
[[email protected] libltdl]# /sbin/ldconfig （配置动态连接器(ld)运行时邦定）
[[email protected] libltdl]# cd libltdl/
[[email protected] libltdl]# ./configure --enable-ltdl-install
[[email protected] libltdl]# make

[[email protected] libltdl]# make install

[[email protected] tar_packet]# tar -zxvf mhash-0.9.9.9.tar.gz -C ../install_packet/
[[email protected] install_packet]# cd mhash-0.9.9.9/

[[email protected] mhash-0.9.9.9]# ./configure
[[email protected] mhash-0.9.9.9]# make
[[email protected] mhash-0.9.9.9]# make install

[[email protected] 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)

[[email protected] install_packet]# ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
[[email protected] install_packet]# ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
[[email protected] install_packet]# ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
[[email protected] install_packet]# ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8

[[email protected] install_packet]# ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
[[email protected] install_packet]# ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
[[email protected] install_packet]# ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
[[email protected] install_packet]# ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
[[email protected] install_packet]# ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1

[[email protected] install_packet]# ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

[[email protected] tar_packet]# tar -zxvf mcrypt-2.6.8.tar.gz -C ../install_packet/
[[email protected] mcrypt-2.6.8]# /sbin/ldconfig

[[email protected] mcrypt-2.6.8]# ./configure
[[email protected] mcrypt-2.6.8]# make
[[email protected] mcrypt-2.6.8]# make install

(2)、安装mysql

[[email protected] tar_packet]# groupadd mysql
[[email protected] tar_packet]# useradd -g mysql mysql
[[email protected] tar_packet]#tar -zxvf mysql-5.5.3-m3.tar.gz -C ../install_packet/

[[email protected] 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

[[email protected] mysql-5.5.3-m3]# make
[[email protected] mysql-5.5.3-m3]# make install
[[email protected] mysql-5.5.3-m3]# cp support-files/my-large.cnf /etc/my.cnf
[[email protected] mysql]# pwd
/usr/local/mysql

[[email protected] 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

[[email protected] 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

...........

[[email protected] mysql]# chown -R root .
[[email protected] mysql]# chown -R mysql var
[[email protected] mysql]# chgrp -R mysql .

[[email protected] mysql]# cp share/mysql/mysql.server /etc/init.d/mysqld
[[email protected] mysql]# chkconfig --add mysqld
[[email protected] mysql]# cd /etc/init.d/
[[email protected] init.d]# chmod +x mysqld
[[email protected] init.d]# chkconfig --list mysqld
mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
[[email protected] init.d]# service mysqld start

mysql> show databases;

(3)、编译安装pHP (fastcgi模式)

[[email protected] tar_packet]# tar -zxvf php-5.2.14.tar.gz -C ../install_packet/

[[email protected] php-5.2.14]# pwd
/home/install_packet/php-5.2.14

[[email protected] install_packet]# gzip -cd php-5.2.14-fpm-0.5.14.diff.gz |patch -d php-5.2.14 -p1

[[email protected] 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

[[email protected] php-5.2.14]# make ZEND_EXTRA_LIBS=‘-liconv‘

[[email protected] php-5.2.14]# make install

[[email protected] php-5.2.14]# cp php.ini-dist /usr/local/php/etc/php.ini

(4)、安装PHP扩展

[[email protected] tar_packet]# tar -zxvf memcache-2.2.5.tgz -C ../install_packet/
[[email protected] memcache-2.2.5]# /usr/local/php/bin/phpize
[[email protected] memcache-2.2.5]# ./configure --with-php-config=/usr/local/php/bin/php-config
[[email protected] memcache-2.2.5]# make
[[email protected] memcache-2.2.5]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/

[[email protected] tar_packet]# tar -jxvf eaccelerator-0.9.6.1.tar.bz2 -C ../install_packet/
[[email protected] install_packet]# cd eaccelerator-0.9.6.1/
[[email protected] eaccelerator-0.9.6.1]# /usr/local/php/bin/phpize
[[email protected] eaccelerator-0.9.6.1]# ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
[[email protected] eaccelerator-0.9.6.1]# make
[[email protected] eaccelerator-0.9.6.1]# make install

[[email protected] tar_packet]# tar -zxvf PDO_MYSQL-1.0.2.tgz -C ../install_packet/
[[email protected] install_packet]# cd PDO_MYSQL-1.0.2/
[[email protected] PDO_MYSQL-1.0.2]# /usr/local/php/bin/phpize
[[email protected] PDO_MYSQL-1.0.2]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-
mysql=/usr/local/mysql
[[email protected] PDO_MYSQL-1.0.2]# make
[[email protected] PDO_MYSQL-1.0.2]# make install

[[email protected] tar_packet]# tar -zxvf ImageMagick.tar.gz -C ../install_packet/
[[email protected] ImageMagick-6.5.1-2]# ./configure
[[email protected] ImageMagick-6.5.1-2]# make
[[email protected] ImageMagick-6.5.1-2]# make install

[[email protected] tar_packet]# tar -zxvf imagick-2.3.0.tgz -C ../install_packet/
[[email protected] install_packet]# cd imagick-2.3.0/
[[email protected] imagick-2.3.0]# /usr/local/php/bin/phpize
[[email protected] imagick-2.3.0]# ./configure --with-php-config=/usr/local/php/bin/php-config
[[email protected] imagick-2.3.0]# make
[[email protected] 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;

[[email protected] 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

[[email protected] ~]# groupadd www
[[email protected] ~]# useradd -g www www

[[email protected] ~]# mkdir -p /web/htdocs/www.nginx.com
[[email protected] ~]# chown -R www:www /web/htdocs/www.nginx.com

[[email protected] ~]# mkdir -p /web/htdocs/web.nginx.com
[[email protected] ~]# 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

1 <?xml version="1.0" ?>
      2 <configuration>
      3
      4         All relative paths in this config are relative to php‘s install prefix

    153
    154         </workers>
    155
    156 </configuration>

（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

[[email protected] pcre-8.10]# ./configure
[[email protected] pcre-8.10]# make
[[email protected] pcre-8.10]# make install

[[email protected] install_packet]# cd nginx-0.8.48/
[[email protected] nginx-0.8.48]# ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
[[email protected] nginx-0.8.48]#make
[[email protected] nginx-0.8.48]#make install

（2）、创建nginx的日志文件
[[email protected] /]# mkdir -p web/nginxlogs
[[email protected] /]# chmod +w web/nginxlogs/
[[email protected] /]# 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 {

     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;

     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

[[email protected] nginx]#/usr/

[[email protected] nginx]# /usr/local/nginx/sbin/nginx
(6)、开机启动nginx 与php

[[email protected] 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

[[email protected] 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

[[email protected] nginxlogs]# kill -HUP `cat /usr/local/nginx/nginx.pid`
或者

[[email protected] nginxlogs]# /usr/loca/nginx/sbin/nginx -s reload

4、测试

在www.nginx.com的文档目录中

[[email protected] 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
