PHP的CGI配置
孔运珧
第2章 PHP(FastCGI)
一、什么是FastCGI
FastCGI是一个可伸缩、高速在HTTP server和动态脚本语言之间的一个通信接口.大多数的HTTP server都支持FastCGI，比如：Nginx Aapache lighttpd等..FastCGI被很多语言所支持。其中就有PHP.
二、Nginx+FastCGI运行原理
(1)Nginx不支持对外程序的直接调用或者解析，所有的外包程序(包括PHP)都必须通过FastCGI来调用
(2)FastCGI接口在Linux下面可以(socket文件的方式存在，那么可以IP)，
(3)为了调用CGI程序，还需要一个FastCGI的wrapper，当Nginx发送CGI的请求给这个socket的时候。通过FastCGI接口wrapper接受到的请求，然后派生出一个新的线程，这个线程调用外部程序或者脚本读却返回数据.
最后wrapper在将返回的数据通过FastCGI接口，沿着固定的socket传递给Nginx，最后返回给数据发送的客户端.
Nginx-->发送一个CGI请求-->FastCGI(warpper)接收到这个请求--->派生出一个新的线程--->调用外部程序或者脚本返回数据--->wrapper将数据沿着固定的socket传递给Nginx-->由Nginx在把这个数据返回给用户.
三、PHP与PHP-FPM的安装与优化
PHP-FPM也是第三方的FastCGI的进程管理，它作为PHP补丁一起开发，编写的时候跟着一起编译到PHP内核当中，PHP-FPM在处理高并发的方面非常的优秀.它的一个有点呢：就是把动态语言和HTTP server分离开来(动静分离)，Http server主要处理静态请求，PHP-FPM处理动态请求。
所有呢 PHP/PHP-FPM 和Nginx经常组合到一块安装到一台机器上，以满足业务需求.
四、首先安装Mysql
(1)首先安装Mysql数据库，PHP在编译的时候需要mysql的一个配置
这样PHP远程链接Mysql才有用
# cd /data/soft/
# tar xf mysql-5.1.49.tar.gz -C tmp/
# cd tmp/mysql-5.1.49/
#CONFOPTS=" \
--with-charset=utf8 \
--with-plugins=partition,federated,innobase,myisam \
--enable-static \
--enable-assembler \
--enable-thread-safe-client \
--with-client-ldflags=-all-static-ltinfo \
--with-mysqld-ldflags=-all-static-ltinfo \
--with-big-tables \
--with-mysqld-user=mysql \
--without-debug \
--without-ndb-debug \
--localstatedir=/usr/local/services/mysql-5.1.49/var \
--prefix=/usr/local/services/mysql-5.1.49 \
"
#./configure $CONFOPTS >/dev/null
# make >/dev/null && make install >/dev/null
五、安装PHP的依赖库

#make >/dev/null && make install >/dev/null
⑦re2c-0.13.5.tar.gz
# cd /data/soft/
# tar xf re2c-0.13.5.tar.gz -C tmp/
# cd tmp/re2c-0.13.5/
#./configure --prefix=/usr/local/services >/dev/null
#make >/dev/null && make install >/dev/null
⑧libmcrypt-2.5.8.tar.gz
# cd /data/soft/
# tar xf libmcrypt-2.5.8.tar.bz2 -C tmp/
# cd tmp/libmcrypt-2.5.8/

#make >/dev/null && make install >/dev/null
# cd libltdl/
# ./configure --prefix=/usr/local/services --enable-ltdl-install >/dev/null

六、安装PHP的依赖库
wget http://php.net/distributions/php-5.3.13.tar.gz
php-5.3.13.tar.gz
# cd /data/soft/
# tar xf php-5.3.13.tar.gz -C tmp/
#cd tmp/php-5.3.13/
#CONFOPTS="
--enable-zend-multibyte \

--enable-sockets \
--enable-pdo \
--enable-zip \
--enable-fpm \
--with-gd \
--with-fpm-user=user_00 \

"
# ./configure $CONFOPTS
# make >/dev/null && make install >/dev/null
编译错误解决：
/var/lib/mysql/mysql.sock
configure: error: Cannot find libmysqlclient under /usr.
Note that the MySQL client library is not bundled anymore!
解决方法：

#./configure --with-php-config=/usr/local/services/php-5.3.13/bin/php-config >/dev/null
#make >/dev/null && make install >/dev/null
九、拷贝配置文件：
# cd /usr/local/services/php-5.3.13/etc
# cp php-fpm.conf.default php-fpm.conf
# cp /soft/php/php-5.3.13/php.ini-production php.ini
7.8、PHP配置文件优化与调整
1.在php-fpm.conf 里面调整.
;listen = 127.0.0.1:9000
listen = /tmp/php-cgi.tuge.sock #以socke的方式访问.注视掉.ip端口的方式.
; Default Value: log/php-fpm.log
error_log = /data/php_log/tuge.php.error #根据不同的项目名.定义不同的.sock 和日志.
# 调整进程数量
pm.max_children：静态方式下开启的php-fpm进程数量。
pm.start_servers：动态方式下的起始php-fpm进程数量。
pm.min_spare_servers：动态方式下的最小php-fpm进程数量。
pm.max_spare_servers：动态方式下的最大php-fpm进程数量。
2.在php.ini 加入扩展模块.
在尾部添加:
[eaccelerator]
zend_extension="/usr/local/services/php-5.3.20/lib/php/extensions/eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
扩展模块增加
extension_dir = "/usr/local/services/php-5.3.13/lib/php/extensions"
extension = memcached.so
extension = redis.so
extension = memcache.so
extension = igbinary.so
3、移动扩展模块位置
# cd /usr/local/services/php-5.3.13/lib/php/extensions/no-debug-non-zts-20090626/
# mv /usr/local/services/php-5.3.13/lib/php/extensions/no-debug-non-zts-20090626/* /usr/local/services/php-5.3.13/lib/php/extensions
十步：启动PHP-FPM
修改Nginx的虚拟主机的sock位置
fastcgi_pass unix:/tmp/php-cgi.gongda.sock;
启动PHP
# cd /usr/local/services/php-5.3.13/sbin
# ./php-fpm
