![nginx 空白页与 puma 和 rails 在 beanstalk 上](https://linux22.com/image/720543/nginx%20%E7%A9%BA%E7%99%BD%E9%A1%B5%E4%B8%8E%20puma%20%E5%92%8C%20rails%20%E5%9C%A8%20beanstalk%20%E4%B8%8A.png)
我尝试将 rails api 部署到 elastic beanstalk,并使用 nginx 和 puma 作为应用服务器。部署成功,数据库已创建并迁移。
但是,当访问网页时,它只显示白页。
我可以看到该请求记录在 nginx 访问日志中,但是它没有记录在 puma 日志中。
以下是 nginx 配置:
> user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local]
"$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
index index.html index.htm;
server {
listen 80 ;
listen [::]:80 ;
server_name localhost;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
# redirect server error pages to the static page /40x.html
#
error_page 404 /404.html;
location = /40x.html {
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
conf 使用 include 指令,其内容如下:upstream my_app { server unix:///var/run/puma/my_app.sock;}
log_format healthd '$msec"$uri"'
'$status"$request_time"$upstream_response_time"'
'$http_x_forwarded_for';
server {
listen 80;
server_name _ localhost; # need to listen to localhost for worker tier
if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
}
access_log /var/log/nginx/access.log main;
access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
location / {
proxy_pass http://my_app; # match the name of upstream directive which is defined above
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /assets {
alias /var/app/current/public/assets;
gzip_static on;
gzip on;
expires max;
add_header Cache-Control public;
}
location /public {
alias /var/app/current/public;
gzip_static on;
gzip on;
expires max;
add_header Cache-Control public;
}
}
我在这里遗漏了什么?
谢谢!

检查你的日志文件,可能是 nginx 配置不正确,如果是的话,你可以参考这些帖子寻找解决方案(https://stackoverflow.com/questions/49360715/elastic-beanstalk-customize-puma-configuration)(https://stackoverflow.com/questions/40938155/right-way-to-deploy-rails-puma-postgres-app-to-elastic-beanstalk)。基本上,您需要通过 ssh 进入您的实例并自定义存储在 /etc/nginx/nginx.conf 中的 nginx 配置文件,您需要在那里将 puma 服务器绑定到 unix 套接字,然后它与 NGINX 连接。NGINX 配置文件示例:
user root;
error_log /var/log/app-nginx-error.log;
pid /var/run/app-nginx.pid;
events {
worker_connections 8096;
multi_accept on;
use epoll;
}
http {
....
include /etc/nginx/mime.types;
default_type application/octet-stream;
upstream appserver {
server unix:///var/run/puma.sock;
}
....
}
您应该添加到 NGINX 配置文件的重要部分是:
upstream appserver {
server unix:///var/run/puma.sock;
}
