　　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

# 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
  


　　All relative paths in this config are relative to php's install prefix
　　
　　Pid file
    /usr/local/php/logs/php-fpm.pid
　　Error log file
    /usr/local/php/logs/php-fpm.log
　　Log level
    notice
　　When this amount of php processes exited with SIGSEGV or SIGBUS ...
    10
　　... in a less than this interval of time, a graceful restart will be initiated.
    Useful to work around accidental curruptions in accelerator's shared memory.
    1m
　　Time limit on waiting child's reaction on signals from master
    5s
　　Set to 'no' to debug fpm
    yes
　　
　　
　　
　　Name of pool. Used in logs and stats.

      127.0.0.1:9000
　　
　　Set listen(2) backlog
        -1
　　Set permissions for unix socket, if one used.
        In Linux read/write permissions must be set in order to allow connections from web server.
        Many BSD-derrived systems allow connections regardless of permissions.
        
        
        0666
      
　　Additional php.ini defines, specific to this pool of workers.
      
        /usr/sbin/sendmail -t -i
        0
      
　　Unix user of processes
      nginx
　　Unix group of processes
      nginx
　　Process manager settings
      
　　Sets style of controling worker process count.
        Valid values are 'static' and 'apache-like'
        static
　　Sets the limit on the number of simultaneous requests that will be served.
        Equivalent to Apache MaxClients directive.
        Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi
        Used with any pm_style.
        64
　　Settings group for 'apache-like' pm style
        
　　Sets the number of server processes created on startup.
          Used only when 'apache-like' pm_style is selected
          20
　　Sets the desired minimum number of idle server processes.
          Used only when 'apache-like' pm_style is selected
          5
　　Sets the desired maximum number of idle server processes.
          Used only when 'apache-like' pm_style is selected
          35
　　
　　
　　The timeout (in seconds) for serving a single request after which the worker process will be terminated
      Should be used when 'max_execution_time' ini option does not stop script execution for some reason
      '0s' means 'off'
      0s
　　The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file
      '0s' means 'off'
      0s
　　The log file for slow requests

　　Redirect workers' stdout and stderr into main error log.
      If not set, they will be redirected to /dev/null, according to FastCGI specs
      yes
　　How much requests each process should execute before respawn.
      Useful to work around memory leaks in 3rd party libraries.
      For endless request processing please specify 0
      Equivalent to PHP_FCGI_MAX_REQUESTS
      1024
　　Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.
      Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)
      Makes sense only with AF_INET listening socket.
      127.0.0.1
　　Pass environment variables like LD_LIBRARY_PATH
      All $VARIABLEs are taken from current environment
      
        $HOSTNAME

        /tmp
        /tmp
        /tmp
        $OSTYPE
        $MACHTYPE
        2
      
　　
　　
　　
　　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;

              '"$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
   
启动nginx
# service nginx restart
测试
http://192.168.0.177
OK 完美的显示
