tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../

2、编译安装PHP（FastCGI模式）
tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
yum install libjpeg-devel  libpng-devel   freetype-devel  -y

make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/php/etc/php.ini
cd ../

3、编译安装PHP5扩展模块
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
cd ../

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
cd ../

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
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.6.5-8/
./configure
make
make install
cd ../

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
cd ../

4、修改php.ini文件
　　手工修改：查找 /usr/local/php/etc/php.ini中的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，即取消注释，使生效，防止Nginx文件类型错误解析漏洞。
自动修改：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改：
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/php/etc/php.ini
sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/php/etc/php.ini

6、配置eAccelerator加速PHP：
mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/php/etc/php.ini
按shift+g键跳到配置文件的最末尾，加上以下配置信息：
引用
[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"
7、创建www用户和组，以及供blog.lamphelp.org和 www.lamphelp.org两个虚拟主机使用的目录：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www

8、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）：
在/usr/local/php/etc/目录中创建php-fpm.conf文件：
rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf
输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：

9、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为128（如果服务器内存小于3GB，可以只开启64个进程），用户为www：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。

--------------------------------------------------------------------------------
三、安装Nginx 0.8.46
1、安装Nginx所需的pcre库：
tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/
./configure
make && make install
cd ../

2、安装Nginx
tar zxvf nginx-0.8.46.tar.gz
cd nginx-0.8.46/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../

3、创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs

4、创建Nginx配置文件
　　①、在/usr/local/nginx/conf/目录中创建nginx.conf文件：
rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/webserver/nginx/conf/nginx.conf
　　输入以下内容：
引用
user  www www;
worker_processes 8;
error_log  /data1/logs/nginx_error.log  crit;

    root  /data0/htdocs/blog;
    #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 fcgi.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" $http_x_forwarded_for';
    access_log  /data1/logs/access.log  access;
      }
  server
  {
    listen       80;
    server_name  www.lamphelp.org ;
    index index.html index.htm index.php;
    root  /data0/htdocs/www;
    location ~ .*\.(php|php5)?$
    {     
      #fastcgi_pass  unix:/tmp/php-cgi.sock;
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      include fcgi.conf;
    }
    log_format  wwwlogs  '$remote_addr - $remote_user [$time_local] "$request" '

               '"$http_user_agent" $http_x_forwarded_for';
    access_log  /data1/logs/wwwlogs.log  wwwlogs;
  }
  server
  {
    listen  80;
    server_name  status.blog.lamphelp.org;
    location / {
    stub_status on;
    access_log   off;
    }
  }
}

　　②、在/usr/local/nginx/conf/目录中创建fcgi.conf文件：
vi /usr/local/nginx/conf/fcgi.conf
输入以下内容：
引用
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;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

5、启动Nginx
ulimit -SHn 65535
/usr/local/nginx/sbin/nginx

--------------------------------------------------------------------------------
四、配置开机自动启动Nginx + PHP
vi /etc/rc.local
在末尾增加以下内容：
引用
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx

--------------------------------------------------------------------------------
五、优化Linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容：
引用
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog =  32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024  65535

　　使配置立即生效：
/sbin/sysctl -p

--------------------------------------------------------------------------------
六、在不停止Nginx服务的情况下平滑变更Nginx配置
1、修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：
/usr/local/nginx/sbin/nginx -t
　　如果屏幕显示以下两行信息，说明配置文件正确：
　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully
2、平滑重启：
　　①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：
/usr/local/webserver/nginx/sbin/nginx -s reload

　　②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
　　屏幕显示的即为Nginx主进程号，例如：
　　6302
　　这时，执行以下命令即可使修改过的Nginx配置文件生效：
kill -HUP 6302
　　或者无需这么麻烦，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

--------------------------------------------------------------------------------
七、编写每天定时切割Nginx日志的脚本
1、创建脚本/usr/local/nginx/sbin/cut_nginx_log.sh
vi /usr/local/nginx/sbin/cut_nginx_log.sh
　　输入以下内容：
引用
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/usr/local/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`

2、设置crontab，每天凌晨00:00切割nginx访问日志
crontab -e
　　输入以下内容：
引用
00 00 * * * /bin/bash  /usr/local/nginx/sbin/cut_nginx_log.sh

________________________________________________

八、测试

echo "blog-test" >> /data0/htdocs/blog/index.html

echo "www-test" >>/data0/htdocs/blog/index.php

然后在浏览器中测试，可以自己做一个DNS，解析两个域名，我这里就不做了，借助window中的hosts文件进行解析
