按照一个应用程序点击部署.数据库做得很好,即使我检查rails控制台一切正常.
Ruby版本是2.3.0,rails版本是5.0.1
但是当我打IP地址时,会出错
在检查独角兽日志我得到

解决方法
这听起来像是独角兽重启问题.你说你不用capistrano.如何部署应用程序？
编辑
独角兽利用多进程架构更好地利用可用的资源.工作开始时,工作人员加载ruby环境,然后产生处理请求的工作人员.主人永远不会处理这个请求,总是工人.
当工作人员花费的时间太长时,主人可以杀死它并重新开始新的工人.
你似乎使用4名工人.我不知道你的水滴在DO上的大小,但似乎主人不能再开始工作了.你能告诉我你的液滴的大小(cpu和内存)吗？
我将安装unicorn-worker-killer gem并再次测试应用程序.这应该以比独角兽大师更有效的方式重新启动你的工人.
编辑2：
如果这不起作用,您可以尝试在Nginx conf文件中替换上游行：
upstream app_server { server 127.0.0.1:8080 fail_timeout=0; }
这在你的独角兽conf文件中：
listen "127.0.0.1:8080
然后重新启动Nginx然后独角兽.

我想我得到了
请你改变你的文件：
unicorn.conf
listen "/var/run/unicorn.sock" worker_processes 4 user "rails" working_directory "/home/rails/company_startup" pid "/var/run/unicorn.pid" stderr_path "/var/log/unicorn/unicorn.log" stdout_path "/var/log/unicorn/unicorn.log"
upstream app_server {
server unix:/var/run/unicorn.sock fail_timeout=0;
}
server {
listen 80;
root /home/rails/company_startup/public;
server_name <PLEASE PUT YOUR SERVER NAME>;
index index.htm index.html;
client_max_body_size 1M;
location / {
try_files $uri/index.html $uri.html $uri @app;
}
location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)${
try_files $uri @app;
}
location @app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
}
重新启动独角兽(请确保替换<>)之间的值
kill -s QUIT $(< /var/run/unicorn.pid) bundle exec unicorn -c <PATH TO unicorn.conf FILE> -E <RAILS ENVIRONMENT> -D
然后重新启动Nginx
sudo service Nginx restart
看看它是否工作.
