nginx中error_page没有生效（nginx+passenger+rails）

Posted 2020-08-14

应用部署方式为 nginx + passenger + rails 

当我想要用nginx来默认处理400以上状态时，发现在rails返回respose之后，nginx不会再次执行error_page（官方介绍该directive在proxy返回response依然会执行），原因在于需要配置 passenger_intercept_errors on ;

nginx.conf 中 server 配置：

    server {
        listen 3443 ssl;
        server_name XXX;
        ssl_certificate /root/ssl/server.crt;
        ssl_certificate_key /root/ssl/server.key;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers HIGH:!aNULL:!MD5;

        root /var/ror/cas/public;

        passenger_enabled on;
        passenger_intercept_errors on;   #问题根源
        passenger_ruby /usr/local/rvm/gems/ruby-2.3.0/wrappers/ruby;

        access_log /var/ror/logs/access.log;
        error_log /var/ror/logs/error.log debug;

        # redirect server error pages to the static page /40x.html
        error_page 404 /404.html;
        location = /404.html {
        }
        error_page 403 = /403.html;
        location = /403.html {
        }

        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
        }
    }
