2. # yum groupinstall 'Development Tools' 'Development Libraries' -y

3.# groupadd nginx
  # useradd -g nginx -s /bin/false -M nginx
4. # tar xvf nginx-0.8.20.tar.gz
   # cd nginx-0.8.20

关于配置选项的简单说明：

--prefix=<path> - The path relative to which all other Nginx paths will resolve. If not

specified, defaults to /usr/local/nginx.

--sbin-path=<path> - The path to the nginx executable. Only used for installation. If not

specified defaults to <prefix>/sbin/nginx.

--conf-path=<path> - The default location of nginx.conf if no -c parameter is provided. If

not provided, defaults to <prefix>/conf/nginx.conf.

--pid-path=<path> - The path to nginx.pid, if not set via the "pid" directive in nginx.conf.

If not provided, defaults to <prefix>/logs/nginx.pid.

--error-log-path=<path> - The location of the error log if not set via the "error_log" in

nginx.conf. If not set, defaults to <prefix>/logs/error.log.

  # chmod +x /etc/init.d/nginxd
  # chkconfig --add nginxd
  # chkconfig  nginxd on
  # service nginxd  start
7. 测试  http://192.168.0.37/
   可以看到   Welcome to nginx! 

修改路径
8. # mkdir -pv /www/htdocs
  
9.   # vim /etc/nginx/nginx.conf
   修改
       user  nginx
      location / {
            root   /www/htdocs;
            index  index.html index.htm;
        }
10. echo '<h1>My nginx</h1>' > /www/htdocs/index.html
11. service nginxd restart
12. 测试  http://192.168.0.37/

二、 安装mysql
1.  tar xvf mysql-5.1.45-linux-i686-glibc23.tar.gz  -C /usr/local/
2.  # cd /usr/local/
    # ln -sv mysql-5.1.45-linux-i686-glibc23/ mysql
3.  添加用户和组
   # groupadd mysql
    # useradd -g mysql -s /sbin/nologin -M mysql
4.
    # cd mysql
    # chown mysql:mysql . -R
    # scripts/mysql_install_db  --user=mysql (初始化)
    # chown -R root .
    # chown -R mysql  data/
5.
    # bin/mysqld_safe  --user=mysql
    # netstat -tnlp （查看3306端口是否打开）
6. 加载mysql的库文件
    # vim /etc/ld.so.conf.d/mysql.conf
     添加库文件路径 “/usr/local/mysql/lib”
    # ldconfig -v  （加载 ）
7.
   加载开发文件
    # ln -sv  /usr/local/mysql/include/ /usr/include/mysql
8.
    启动文件
    # cp support-files/mysql.server  /etc/init.d/mysqld
    # chkconfig --add mysqld （加到自动启动队列）
    # chkconfig  mysqld on    （开机自动启动）
9.  调整配置文件
    # cp support-files/my-large.cnf  /etc/my.cnf
10. 验证   重启服务
    service mysqld restart
11. 
    # vim /etc/profile
       找到 ‘export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC’
       在前一行添加
       PATH=$PATH:/usr/local/mysql/bin
    # . /etc/profile
    # mysql  (即可进入mysql的命令行)

三、 安装php
1.  安装libevent (调度文件时依赖于这个库文件)
    # tar xvf libevent-1.4.14b-stable.tar.gz
    # cd libevent-1.4.14b-stable
    # ./configure
    # make && make install
2   安装 libiconv（建立会话是用来实现网络解析方式的一种组件，有利于加速网络访问）
    # tar xvf libiconv-1.13.1.tar.gz
    # cd libiconv-1.13.1
    # ./configure
    # make && make install
3. 安装php
   # tar xvf php-5.3.3.tar.bz2
   # cd php-5.3.3
   # ./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl  --

enable-fpm --with-libevent-dir=/usr/local --with-mysqli=/usr/local/mysql/bin/mysql_config --

enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml

-dir=/usr --enable-xml --with-iconv-dir=/usr/local
   # make ZEND_EXTRA_LIBS='-liconv'
   # make install
   # cp php.ini-production  /usr/local/php/etc/php.ini

   # cd /usr/local/php/etc/
   # cp php-fpm.conf.default  php-fpm.conf
   # vim php-fpm.conf
   启用
          pm.start_servers = 20
          pm.min_spare_servers = 5
          pm.max_spare_servers = 35
          pm.max_requests = 500
   启动服务：
   # /usr/local/php/sbin/php-fpm
   查看9000端口是否打开
   设置开机启动
   # vim /etc/rc.d/rc.local
      加入  /usr/local/php/sbin/php-fpm
   
四、配置
1、 编辑主配置文件
   # vim /etc/nginx/nginx.conf
    修改一下两段内容为：
       location / {
            root   /www/htdocs;
            index index.php  index.html index.htm;
        }
   
    location ~ \.php$ {
            root           /www/htdocs;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }

   # vim /etc/nginx/fastcgi_params
     修改为：
    fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;
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_FILENAME    $document_root$fastcgi_script_name;
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  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;
2.    # service nginxd restart
      # vim /www/htdocs/index.php
      <?php
         phpinfo()
      ?>
