Question

我正在通过Capistrano 3将我的应用程序部署到Ubuntu服务器，部署过程顺利进行，没有任何问题，但是当我加载我的网站（IP）时，我只收到错误消息 502 Bad Gateway

我的设置：

deploy.rb ：

lock "3.8.1"

set :application, "project"
set :repo_url, "git@bitbucket.org:username/project.git"
set :branch, "master"
set :tmp_dir, '/home/deployer/tmp'

#set :rvm_ruby_version, '2.4.0'      # Defaults to: 'default'

# Default branch is :master
# ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp

# Default deploy_to directory is /var/www/my_app_name
# set :deploy_to, "/var/www/my_app_name"

# Default value for :format is :airbrussh.
# set :format, :airbrussh

# You can configure the Airbrussh format using :format_options.
# These are the defaults.
# set :format_options, command_output: true, log_file: "log/capistrano.log", color: :auto, truncate: :auto

# Default value for :pty is false

# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }

# Default value for keep_releases is 5
set :keep_releases, 5

服务器上的

来自 /var/log/nginx/error.log 的

错误日志：

2017/07/26 06:57:55 [crit] 25631#25631: *1879 connect() to unix:/tmp/unicorn.project.sock failed (2: No such file or directory) while connecting to upstream, client: IP, server: , request: "GET /favicon.ico HTTP/1.1", upstream: "http://unix:/tmp/unicorn.project.sock:/500.html", host: "IP", referrer: "http://IP/"

如何解决此错误消息？我检查了路径，它应该是正确的，而不是拼写错误等。

另外，我不会错过 deploy.rb 中的任何内容（符号链接？）到＆＃34;刷新＆＃34; / etc / nginx / sites-enabled / default 文件？

感谢您的每一次进步。
