centos7系统nginx下phalcon环境搭建

之前我们采用的是Apache服务器，可是每秒响应只能达到2000，听说nginx可以轻易破万，

于是换成nginx试试。

phalcon的官网有nginx重写规则的示例，可是却与apache的不一致，被坑了好久。

1、添加nginx源

vi /etc/yum.repos.d/nginx.repo

 [nginx]
     name=nginx repo
     baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
     gpgcheck=0
     enabled=1

2、修改nginx的配置

vi /etc/nginx/conf.d/default.conf

server {
    listen 80;

    server_name localhost.dev;

    index index.php index.html index.htm;

    root /var/www/html;

    location / {
        root /var/www/html; #phalcon官网上是public目录，如果用这个目录就和apache的配置不一样了
      
        index  index.php index.html index.htm;

        # 如果文件存在就直接返回这个文件

　　　　　if (-f $request_filename) {
            break;
        }

        # 如果不存在就重定向到public/index.php
        if (!-e $request_filename) {
            rewrite ^(.+)$ /public/index.php?_url=$1 last;
            break;
        }
    }

    location ~ .php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+.php)(/.+)$;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include fastcgi_params;
    }

    location ~* ^/(css|img|js|flv|swf|download)/(.+)$ {
        root /var/www/html/public;
    }

    location ~ /.ht {
        deny all;
    }
}

3、php-fpm的配置

vi /etc/php-fpm.d/www.conf 

修改为用户和用户组

; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx

4、用户组修改

chown -R nginx:nginx /var/lib/php/session/

chown -R nginx:nginx /var/www/html/

重启nginx、php-fpm，
systemctl restart nginx
systemctl restart php-fpm
进一步的优化且待之后的情况
