一.FastCGI概述
1>.CGI的由来
最早的Web服务器只能简单地响应浏览器发来的HTTP请求，并将存储在服务器上的HTML文件返回给浏览器，也就是静态html文件，但是后期随着网站功能增多网站开发也越来越复杂，以至于出现动态技术，比如像php(1995年)、java(1995)、python(1991)语言开发的网站，但是nginx/apache服务器并不能直接运行php、java这样的文件。
apache实现的方式是打补丁，但是nginx缺通过与第三方基于协议实现，即通过某种特定协议将客户端请求转发给第三方服务处理，第三方服务器会新建新的进程处理用户的请求，处理完成后返回数据给Nginx并回收进程，最后nginx在返回给客户端，那这个约定就是通用网关接口(common gateway interface，简称CGI)，CGI（协议）是web服务器和外部应用程序之间的接口标准，是cgi程序和web服务器之间传递信息的标准化接口。
2>.为什么FastCGI
CGI协议虽然解决了语言解析器和seb server之间通讯的问题，但是它的效率很低，因为web server每收到一个请求都会创建一个CGI进程，PHP解析器都会解析php.ini文件，初始化环境，请求结束的时候再关闭进程，对于每一个创建的CGI进程都会执行这些操作，所以效率很低，而FastCGI是用来提高CGI性能的，FastCGI每次处理完请求之后不会关闭掉进程，而是保留这个进程，使这个进程可以处理多个请求。这样的话每个请求都不用再重新创建一个进程了，大大提升了处理效率。
3>.什么是PHP-FPM
PHP-FPM(FastCGI Process Manager：FastCGI进程管理器)是一个实现了Fastcgi的程序，并且提供进程管理的功能。进程包括master进程和worker进程。master进程只有一个，负责监听端口，接受来自webserver的请求。worker进程一般会有多个，每个进程中会嵌入一个PHP解析器，进行PHP代码的处理。
二.Nginx与php-fpm在同一服务器实战案例
1>.安装php相关软件环境

3>.php相关参数优化（优化参数的具体意思可以参考Nginx和PHP部署在同一台服务器的PHP调优笔记）
[root@node106.yinzhengjie.org.cn ~]# egrep -v "^;|^$|^ " /opt/remi/php56/root/etc/php-fpm.d/www.conf #这是清华源默认安装的php的存放PHP文件的路径，以下为默认配置 [www] user = apache group = apache listen = 127.0.0.1:9000 listen.allowed_clients = 127.0.0.1 pm = dynamic pm.max_children = 50 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 35 slowlog = /opt/remi/php56/root/var/log/php-fpm/www-slow.log php_admin_value[error_log] = /opt/remi/php56/root/var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on php_value[session.save_handler] = files php_value[session.save_path] = /opt/remi/php56/root/var/lib/php/session php_value[soap.wsdl_cache_dir] = /opt/remi/php56/root/var/lib/php/wsdlcache [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# vim /opt/remi/php56/root/etc/php-fpm.d/www.conf [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# egrep -v "^;|^$|^ " /opt/remi/php56/root/etc/php-fpm.d/www.conf #需要根据实际情况进行调优 [www] user = nginx #注意，使用nginx用户管理php程序那就得有nginx用户哟~ group = nginx listen = 172.30.1.106:9000 #监听本地地址 listen.allowed_clients = 172.30.1.101 #允许访问的客户端IP地址 pm = dynamic pm.max_children = 500 pm.start_servers = 100 pm.min_spare_servers = 100 pm.max_spare_servers = 200 pm.max_requests = 500000 pm.status_path = /my_php_status ping.path = /ping ping.response = ping-pong slowlog = /opt/remi/php56/root/var/log/php-fpm/www-slow.log php_admin_value[error_log] = /opt/remi/php56/root/var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on php_value[session.save_handler] = files php_value[session.save_path] = /opt/remi/php56/root/var/lib/php/session php_value[soap.wsdl_cache_dir] = /opt/remi/php56/root/var/lib/php/wsdlcache [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]#
4>.创建nginx用户并启动php服务
[root@node106.yinzhengjie.org.cn ~]# useradd nginx -u 2000 #该用户的uid最好和Nginx服务器的uid要一致哟~ [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# id nginx uid=2000(nginx) gid=2000(nginx) groups=2000(nginx) [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 128 :::22 :::* [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# systemctl start php56-php-fpm #启动php服务 [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 172.30.1.106:9000 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 :::22 :::* [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]#
5>.PHP节点创建存放php目录
[root@node106.yinzhengjie.org.cn ~]# mkdir -pv /yinzhengjie/data/web/php #该目录会在Nginx配置文件中指定 mkdir: created directory ‘/yinzhengjie’ mkdir: created directory ‘/yinzhengjie/data’ mkdir: created directory ‘/yinzhengjie/data/web’ mkdir: created directory ‘/yinzhengjie/data/web/php’ [root@node106.yinzhengjie.org.cn ~]# [root@node106.yinzhengjie.org.cn ~]# cat /yinzhengjie/data/web/php/index.php #编写PHP测试数据，也可以直接将Nginx节点的PHP相关文件拷贝到改目录即可 <?php phpinfo(); ?> [root@node106.yinzhengjie.org.cn ~]#
6>.修改Nginx的配置文件
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/node101_yinzhengjie_org.cn.conf server { listen 80; listen 443 ssl; server_name node101.yinzhengjie.org.cn; access_log /yinzhengjie/softwares/nginx/logs/node101_yinzhengjie_org_cn_access.log my_access_json; error_log /yinzhengjie/softwares/nginx/logs/node101_yinzhengjie_org_cn_error.log; location / { root /yinzhengjie/data/web/nginx; index index.html; } location = /favicon.ico { root /yinzhengjie/data/web/nginx/images/jd; } location ~ \.php$ { #"$document_root"会调用root目录,若不写root指令对应的目录路径,则"$document_root"所对应的值为空. #root /yinzhengjie/data/web/php; #指定PHP服务器地址 fastcgi_pass 172.30.1.106:9000; fastcgi_index index.php; #fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; #如果"SCRIPT_FILENAME"后面是绝对路径则可以省略上面的"root /data/nginx/php;" fastcgi_param SCRIPT_FILENAME /yinzhengjie/data/web/php$fastcgi_script_name; #千万别忘记添加改行,若不添加"include fastcgi_params;"尽管上面配置的都正确，nginx也无法将fastcgi程序的处理结果返回给浏览器,返回给浏览器的只能是一个零字节的文件。 include fastcgi_params; } } [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# nginx -t nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful [root@node101.yinzhengjie.org.cn ~]#
7>.重新加载Nginx的配置
[root@node101.yinzhengjie.org.cn ~]# rm -rf /yinzhengjie/data/web/php #Nginx节点是可以删除之前存放较久的PHP文件，因为目前PHP目录压根不在Nginx上存放，而是在node106.yinzhengjie.org.cn中存放着。 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# nginx -s reload #重新加载Nginx程序 [root@node101.yinzhengjie.org.cn ~]#
8>.浏览器访问"http://node101.yinzhengjie.org.cn/index.php",如下图所示，php版本为5.6的啦~
