一、编译安装nginx
1.安装辅助包
 # yum groupinstall "Development Libraries" "Development Tools"
 # yum install gcc openssl-devel pcre pcre-devel zlib-devel
2.安装nginx
创建用户和组
# groupadd nginx
# useradd -g nginx -s /bin/false -M nginx

# tar xvf nginx-1.1.3.tar.gz
# cd nginx-1.1.3
# ./configure   --prefix=/usr   --sbin-path=/usr/sbin/nginx   --conf-path=/etc/nginx/nginx.conf   --error-log-path=/var/log/nginx/error.log   --http-log-path=/var/log/nginx/access.log   --pid-path=/var/run/nginx/nginx.pid    --lock-path=/var/lock/nginx.lock   --user=nginx   --group=nginx   --with-http_ssl_module   --with-http_flv_module   --with-http_stub_status_module   --with-http_gzip_static_module   --http-client-body-temp-path=/var/tmp/nginx/client/   --http-proxy-temp-path=/var/tmp/nginx/proxy/   --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/   --with-pcre

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
 
lockfile=/var/lock/subsys/nginx
 
make_dirs() {
   # make required directories

    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}
 
stop() {
    echo -n $"Stopping $prog: "

# chmod +x /etc/init.d/nginx

二、安装mysql（二进制安装）

# tar xvf mysql-5.1.46-linux-i686-glibc23.tar.gz -C /usr/local/

# cd /usr/local/
# ln -sv mysql-5.1.46-linux-i686-glibc23 mysql
# cd mysql
# groupadd mysql
# useradd -g mysql -s /sbin/nologin -M -r mysql
# mkdir /data
# chown -R mysql:mysql /data
# chown mysql:mysql . -R
# scripts/mysql_install_db --user=mysql --datadir=/data
# chown root . -R 
# cp support-files/my-large.cnf /etc/my.cnf
# vim /etc/my.cnf
          datadir = /data
#  bin/mysqld_safe --user=mysql &
#  netstat -tnlp
#  vim /etc/profile
     PATH=$PATH:/usr/local/mysql/bin
# . /etc/profile
  
#  vim /etc/ld.so.conf.d/mysql.conf
    /usr/local/mysql/lib
#  ldconfig -v
#  ln -sv /usr/local/mysql/include/ /usr/include/mysql
#  cp support-files/mysql.server /etc/init.d/mysqld
#  chkconfig --add mysqld
#  chkconfig mysqld on
#  service mysqld restart

 

三、编译安装php （fastcgi模式）
1、编译安装PHP 5.2.14所需的支持库
# tar xvf libiconv-1.13.1.tar.gz
# cd libiconv-1.13.1 
# ./configure --prefix=/usr/local
# make && make install

# tar xvf libevent-1.4.14b-stable.tar.gz
# cd libevent-1.4.14b-stable
# ./configure
# make && make isntall

# tar xvf libmcrypt-2.5.8.tar.gz
# cd libmcrypt-2.5.8
# ./configure
# make && make install
# ldconfig -v
# cd libltdl/
# ./configure --enable-ltdl-install
# make && make install  

# tar xvf mhash-0.9.9.9.tar.bz2
# cd mhash-0.9.9.9
# ./configure
# make && make install
 
# ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
# ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
# ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
# ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
# ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
# ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
# ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
# ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
# ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
# ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
 
 
 
2.编译安装php（fastcgi模式）
# tar xvf php-5.2.14.tar.bz2
yum install libxml2-devel
# gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
# cd 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
# make ZEND_EXTRA_LIBS='-liconv'  ##可能是因为机器没有安装libiconv之类的库，怕编译出错，所以不为php加入iconv模块吧。

# make install
# cp php.ini-dist /usr/local/php/etc/php.ini
3.安装php的一些扩展模块儿
# tar xvf mcrypt-2.6.8.tar.gz
# cd mcrypt-2.6.8
# /sbin/ldconfig
# ./configure
# make && make install

# tar zxvf memcache-2.2.5.tgz
# cd memcache-2.2.5/
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make
# make install

# tar jxvf eaccelerator-0.9.6.1.tar.bz2
# cd eaccelerator-0.9.6.1/
# /usr/local/php/bin/phpize
# ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
# make
# make install

# tar zxvf PDO_MYSQL-1.0.2.tgz
# cd PDO_MYSQL-1.0.2/
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
# make
# make install

# tar xvf ImageMagick-6.5.1-2.tar.bz2
# cd ImageMagick-6.5.1-2/
# ./configure
# make
# make install

# tar zxvf imagick-2.3.0.tgz
# cd imagick-2.3.0/
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make
# make install

4.修改php.ini文件
# vim /usr/local/php/etc/php.ini
   查找    extension_dir = "./"
　 修改为  extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
　　并在此行后增加以下几行，然后保存：
　　extension = "memcache.so"
　　extension = "pdo_mysql.so"
　　extension = "imagick.so"

　　再查找   output_buffering = Off
　　修改为   output_buffering = On

　　再查找   ;cgi.fix_pathinfo=0
　　修改为   cgi.fix_pathinfo=0    防止Nginx文件类型错误解析漏洞。

5、配置eAccelerator加速PHP

# mkdir -p /usr/local/eaccelerator_cache
# vim /usr/local/php/etc/php.ini
 在最后添加以下内容
[eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
 
6. 创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：
# mv /usr/local/php/etc/php-fpm.conf /usr/local/php/etc/php-fpm.conf.bak
# vim /usr/local/php/etc/php-fpm.conf
 
<?xml version="1.0" ?>

</configuration>

7.启动php-cgi进程，监听127.0.0.1的9000端口，进程数为64（如果服务器内存大于3GB，可以只开启128个进程或者更高，这个根据自己的配置来修改）
# ulimit -SHn 65535
# /usr/local/php/sbin/php-fpm start

# vim /etc/nginx/fastcgi.conf

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

四、配置nginx以提供服务
编辑配置文件
# vim /etc/nginx/nginx.conf
#####以下是本人的配置文档，仅供参考
#user  nobody;

worker_processes 4;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events
{

  worker_connections 51200;
}

http
{
  include       mime.types;
  default_type  application/octet-stream;

  #charset  gb2312;
     
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 8m;
     
  sendfile on;
  tcp_nopush     on;

  keepalive_timeout 60;

  tcp_nodelay on;

  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;

  gzip on;
  gzip_min_length  1k;
  gzip_buffers     4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_types       text/plain application/x-javascript text/css application/xml;
  gzip_vary on;

  #limit_zone  crawler  $binary_remote_addr  10m;

  server
  {
    listen       80;
    server_name  192.168.0.90;
    index index.html index.htm index.php;
    root  /nginx;

    #limit_conn   crawler  20;   
                            
    location ~ .*\.(php|php5)?$
    {     
      #fastcgi_pass  unix:/tmp/php-cgi.sock;
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
    }
   
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
      expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
      expires      1h;
    }   

    log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
    access_log  /nginx/logs/access.log  access;
      }

}

创建日志目录
# mkdir -pv /nginx/logs
# mkdir /var/tmp/nginx/nginx.conf -pv
编辑php测试页
# cd /nginx
# vim index.php
  <?php
  phpinfo();
  ?> 
启动nginx
# service nginx restart
测试
http://192.168.0.177
OK 完美的显示
