ruby-on-rails - Nginx/Passenger 的 Rails 应用程序错误

Question

我刚刚将 Capistrano 部署到带有 Linux Server (14.04)、Nginx、PHP5-FPM(用于 phpMyAdmin)、MySQL、Passenger 的服务器上。

一切正常，但是当我尝试从浏览器访问 Rails 应用程序时出现错误。我去检查了 Log Nginx，我得到了以下信息:

App 15973 stdout: 
App 15973 stderr:  [passenger_native_support.so] trying to compile for the current user (deploy) and Ruby interpreter...
App 15973 stderr:      (set PASSENGER_COMPILE_NATIVE_SUPPORT_BINARY=0 to disable)
App 15973 stderr:      Warning: compilation didn't succeed. To learn why, read this file:
App 15973 stderr:      /tmp/passenger_native_support-a97tab.log
App 15973 stderr:  [passenger_native_support.so] not downloading because passenger wasn't installed from a release package
App 15973 stderr:  [passenger_native_support.so] will not be used (can't compile or download) 
App 15973 stderr:   --> Passenger will still operate normally.
App 16021 stdout: 

然后:

$cat /tmp/passenger_native_support-a97tab.log

# current user is: deploy
# mkdir -p /usr/lib/buildout/ruby/ruby-2.2.1-x86_64-linux
Encountered permission error, trying a different directory...
-------------------------------
# mkdir -p /home/deploy/.passenger/native_support/5.0.26/ruby-2.2.1-x86_64-linux
# cd /home/deploy/.passenger/native_support/5.0.26/ruby-2.2.1-x86_64-linux
# /home/deploy/.rbenv/versions/2.2.1/bin/ruby /usr/lib/src/ruby_native_extension/extconf.rb
/home/deploy/.rbenv/versions/2.2.1/bin/ruby: No such file or directory -- /usr/lib/src/ruby_native_extension/extconf.rb (LoadError)

这是怎么回事？

这是我的 Nginx 默认文件:

# Default server configuration
#
server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!
    #
    # include snippets/snakeoil.conf;

    # root /usr/share/nginx/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.php index.nginx-debian.html;

    server_name _;

    passenger_enabled on;
        rails_env    development;
        root         /home/deploy/highschool/current/public;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
          root /usr/share/nginx/html;
    }

    location ~ \.php$ {
          try_files $uri =404;
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass unix:/var/run/php5-fpm.sock;
          fastcgi_index index.php;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          include fastcgi_params;
    }
}

还有我的 Nginx.conf

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    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;


    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;
    gzip_disable "msie6";

    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Phusion Passenger config
    ##
    # Uncomment it if you installed passenger or passenger-enterprise
    ##

    passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
    passenger_ruby /home/deploy/.rbenv/shims/ruby;

    # passenger_ruby /usr/bin/passenger_free_ruby;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

我将 RBENV 用于 Ruby 版本。

对不起我的英语。

Answer 1

我找到了解决方案。

在我的服务器中，我将以下命令运行到我的 Rails 应用程序中:$ passenger-config build-native-support。编译正确并向我展示了 ruby_native_extension/extconf.rb 或 ruby_native_extension 目录的真实路径。

我只创建一个从/usr/lib/src/ 到ruby_native_extension 目录的符号链接(symbolic link)，然后重启Nginx。

当我这样做时，错误消失了，但是登录(设计)不起作用，总是出现 404 错误。因此，(如果发生任何情况)我专门为路线 sign_in 添加了一些行。

在我的 Nginx 默认文件中，我添加了以下内容:

location /users/sign_in {
  passenger_enabled on
}

并编辑:

location / {
   # First attempt to serve request as file, then
   # as directory, then fall back to displaying a 404.
   passenger_enabled on
   try_files $uri $uri/ =404;
}

通过这些更改，我的 Rails 应用程序正在运行。
