Question

我有一台使用Ruby，Sinatra，Unicorn和nginx的服务器。我最近遇到了崩溃，在终端运行时重新产生了问题，我可以看到它产生了这个崩溃日志：

/Users/Andrew/.rvm/gems/ruby-2.3.0/gems/tweetstream-2.6.1/lib/tweetstream/client.rb:449:in `block in connect': Failed to reconnect after 6 tries. (TweetStream::ReconnectError)
    from /Users/Andrew/.rvm/gems/ruby-2.3.0/gems/em-twitter-0.3.5/lib/em-twitter/connection.rb:297:in `invoke_callback'

    from server.rb:234:in `<main>'

但是当我之前寻找错误日志时，我找不到类似上面的内容。

我的/etc/nginx/nginx.conf文件将此显示为日志的位置：

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

但我转到这两个目录，访问日志只显示所有请求，正如我所料，错误日志为空。

如果我的日志存储在其他地方，我该如何确定它的位置？或者，如果由于某种原因没有记录崩溃，我该如何确保崩溃？

我建议您在stderr文件中为独角兽设置stdout和unicorn.rb日志。

# set path to app that will be used to configure unicorn,
# note the trailing slash in this example
@dir = File.dirname(__FILE__) + '/'

worker_processes 2
working_directory @dir

timeout 30

# Specify path to socket unicorn listens to,
# we will use this in our nginx.conf later
listen "/home/vagrant/sockets/unicorn.sock", :backlog => 64

# Set process id path
pid "#{@dir}tmp/pids/unicorn.pid"

# Set log file paths
stderr_path "/var/log/unicorn/stderr.log"
stdout_path "/var/log/unicorn/stdout.log"

与Unicorn和Sinatra的nginx服务器没有记录崩溃
