3、编译安装PHP(FastCGI模式)
tar -zxvf php-5.2.10.tar.gz
//下面一步针对php-5.3.3的版本不需要执行,直接编译即可
gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1
cd php-5.2.10/
./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-xmlrpc --enable-zip --enable-ftp
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/php/etc/php.ini
cd ../
curl | /usr/local/php/bin/php


  4、编译安装PHP5扩展模块
-----------------------------------memcache---------------------------------------
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 ../

-----------------------------------eaccelerator------------------------------------
tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/
/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

-----------------------------------PDO_MYSQL------------------------------------
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 ../

-----------------------------------PDO_MYSQL------------------------------------
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../

-----------------------------------imagick------------------------------------
tar zxvf imagick-2.2.2.tgz
cd imagick-2.2.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../



  5、修改php.ini文件
     手工修改: 

    查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
  修改为extension_dir = "/usr/local/webserver/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


     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/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


  6、配置eAccelerator加速PHP:
mkdir -p /usr/local/eaccelerator_cache
cat >>/usr/local/php/etc/php.ini<[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″
eaccelerator.keys = “disk_only”
eaccelerator.sessions = “disk_only”
eaccelerator.content = “disk_only”
EOF


  7、创建www用户和组,以及供虚拟主机使用的目录:
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /web/www
chmod +w /web/www
chown -R www:www /web/www
mkdir -p /www/html/
chmod +w /www/html/
chown -R www:www /www/html/

 

 

  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/webserver/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0改为1,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):  

 

  
  
  
  All relative paths in this config are relative to php's install prefix

        Many BSD-derrived systems allow connections regardless of permissions.   
          
          
        0666  
     
  
  
      Additional php.ini defines, specific to this pool of workers.

        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.   
        128  
  
        Settings group for 'apache-like' pm style

      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   
      102400  
  
      Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.

  9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为200(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/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。
