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
