它是我第一次設置nginx和獨角獸。在上游「應用程序」中找不到主機nginx不在應用程序中停留在歡迎頁上

我的capistrano部署已經完成，一切都成功了。

here is my unicorn.rb 

#app_dir = File.expand_path('../../', __FILE__) 
#shared_dir = File.expand_path('../../../shared/', __FILE__) 

preload_app true 
worker_processes 4 
timeout 30 
working_directory "home/deploy/appname" 
shared_dir = "home/deploy/appname/shared" 

# Set up socket location 
# by default unicorn listens on 8080 
listen "#{shared_dir}/tmp/sockets/unicorn.sock", :backlog => 64 

# Logging 
stderr_path "#{shared_dir}/log/unicorn.stderr.log" 
stdout_path "#{shared_dir}/log/unicorn.stdout.log" 

# Set master PID location 
pid "#{shared_dir}/tmp/pids/unicorn.pid" 

#must set preload app true to use before/after fork 
before_fork do |server, worker| 
    defined?(ActiveRecord::Base) and ActiveRecord::Base.connection.disconnect! 

    #before forking, this is suppose to kill the master process that belongs to the oldbin 
    #enables 0 downtime to deploy 

    old_pid = "#{shared_dir}/tmp/pids/unicorn.pid.oldbin" 
    if File.exists?(old_pid) && server.pid != old_pid 
    begin 
     Process.kill("QUIT", File.read(old_pid).to_i) 
    rescue Errno::ENOENT, Errno::ESRCH 
    end 
    end 
end 

after_fork do |server, worker| 
    defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection 
end 

# before_exec do |server| 
# ENV['BUNDLE_GEMFILE'] = "#{app_dir}/Gemfile" 
# end

處/etc/nginx/nginx.conf

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

events { 
     worker_connections 768; 
     # multi_accept on; 
} 


http { 
     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; 

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


     gzip on; 
     gzip_disable "msie6"; 

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

我的默認文件我的nginx的conf的/ etc/nginx的/ /默認

upstream app_server { 
    #path to unicorn sock file, as defined previously 
    server unix:/home/deploy/appname/shared/tmp/sockets/unicorn.sock fail_timeout=0; 
} 

    server { 
     listen 80; 

     root /home/deploy/appname; 

    try_files $uri/index.html $uri @app; 

     #click tracking 
     access_log /var/log/nginx/appname_access.log combined; 

     error_log /var/log/nginx/appname_error.log; 

     location @app { 
      proxy_set_header X-Forwarded-For $remote_addr; 
      proxy_set_header Host $http_host; 
      proxy_redirect off; 
      proxy_pass http://app; 
     } 

     error_page 500 502 503 504 /500.html; 
     client_max_body_size 4G; 
     keepalive_timeout 10; 
    }

當我啓用的站點 - 這

[email protected]:~$ sudo nginx -s reload 
nginx: [emerg] host not found in upstream "app" in /etc/nginx/sites-enabled/default:46

當我進入

/shared/tmp/sockets

我沒有在那裏的文件。我認爲我不應該手動創建它。我正在使用capistrano 3.我想生成這個文件嗎？

我在deploy.rb

象徵性的文件和目錄

set :linked_files, %w{config/database.yml config/secrets.yml} 
set :linked_dirs, %w{tmp/pids tmp/cache tmp/sockets log bin vendor/bundle public/system} 

#just pointing to our unicorn.rb 
set :unicorn_config_path, "config/unicorn.rb" 

#capistrano tasks and processes 

after "deploy", "deploy:cleanup" 

namespace :deploy do 

    desc 'Restart application' 
    task :restart do 
    on roles(:app), in: :sequence, wait: 5 do 
     invoke 'unicorn:restart' 
    end 
    end 

    after :finishing, "deploy:cleanup" 

end

我把我的帽子文件，在這裏，因爲我發現在我的帽子上麒麟重新啓動的日誌使用

require 'capistrano3/unicorn' #in capfile

生產部署日誌。我不確定這是否有幫助。

我確保working_directory匹配默認nginx頁面中的根目錄。我確保在獨角獸中的偵聽與默認頁面中的上游應用程序服務器unix相匹配。我確保nginx.conf文件包含啓用網站的默認配置nginx頁面。

那麼這是6個月大，但我要回答它。問題是sites_enabled/default中的@app中的proxy_pass。它試圖傳遞給上游服務器http://app，但您沒有該上游設置，您將其命名爲app_server。

您需要重命名： proxy_pass http://app

到： proxy_pass http://app_server
