我正在尝试使用Nginx和带有Opcache的PHP5.5-FPM进行原子部署。
这个想法只是在nginx.conf中更改webroot，然后运行
nginx重新加载
我所期望的是，Nginx将等待当前请求结束，然后重新加载自己，将新的webroot路径传递给PHP FPM，但它不起作用：PHP FPM仍在从旧目录加载PHP文件。我在Ngnix中使用（未记录的）$realpath_root，目的不是获取符号链接（/prod/current），而是获取真实路径。该技术记录如下：http://codeascraft.com/2013/07/01/atomic-deploys-at-etsy/调试Nginx我可以清楚地看到它正在通过新的（真实的）路径。

为了让它发挥作用，我必须运行
php fpm重新加载
但我失去了一些请求。
从上游读取响应标头时，recv（）失败（104:对等方重置连接）
这是我正在使用的nginx文件：
server {
listen 26023;
server_name prod.example.com;
client_max_body_size 20m;
client_header_timeout 1200;
client_body_timeout 1200;
send_timeout 1200;
keepalive_timeout 1200;
access_log /var/logs/prod/nginx/prod.access.log main;
error_log /var/logs/prod/nginx/prod.error.log;
set $root_location /var/www/htdocs/prod/current/web;
root $root_location;
try_files $uri $uri/ /index.php?$args;
index index.php;
location ~ .php$ {
fastcgi_pass unix:/var/run/php5-fpm/prod.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_connect_timeout 1200;
fastcgi_send_timeout 1200;
fastcgi_read_timeout 1200;
fastcgi_ignore_client_abort on;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
fastcgi_param APPLICATION_ENV live;
fastcgi_param HTTPS $thttps;
}
}
这是池配置文件：
:~$ curl http://127.0.0.1/fpm_status_prod
pool: prod
process manager: dynamic

有什么建议吗？
我修复了这个问题，我也使用APC作为类加载器，但它没有被清除。
