I am trying to build an environment with sinatra + unicorn + nginx.
However, I am having trouble starting unicorn with an error.
Please help me.
Environment
Error Contents
FATAL--:error adding listener addr=/var/www/html/unicorn/tmp/sockets/unicorn.sock
/var/wwww/html/unicorn/vendor/bundler/ruby/1.9.1/gems/unicorn-4.8.3/lib/unicorn/socket_helper.rb: 158: in `initialize': Operation not permitted -"/var/wwww/html/unicorn/tmp/sockets/unicorno: EPM:
unicorn.rb is as follows:
@dir=File.expand_path("/var/www/html/unicorn",__FILE__)
worker_processes2
working_directory@dir
timeout 300
listen"/var/www/html/unicorn/tmp/sockets/unicorn.sock", —backlog=>1024
pid"#{@dir}/tmp/pids/unicorn.pid"
stderr_path"#{@dir}/log/unicorn.stderr.log"
stdout_path"#{@dir}/log/unicorn.stdout.log"
If you set listen to 3000, it will start well.
I don't know if this .socket file will be created on my own, or if I will prepare and load it myself, but I tried /var/www/html/unicorn/tmp/sockets/ permission, but the result was the same.
Even if I googled, I could only find items that said listen should be the absolute pass, so please let me know.
I look forward to your kind cooperation.
If you set listen to 3000 and so on, it will start well.
I heard that unicorn uses 8080 by default, but is it possible that another server process uses 8080 port? Why don't you use the netstat or lsof commands to check?Specifically, do the following with root privileges:
netstat
# netstat-tlnp | grep':8080'
lsof
# lsof-i TCP:8080
netstat
# netstat-tlnp | grep':8080'
lsof
# lsof-i TCP:8080
The first quote from English version of the same question is that the unix domain socket cannot be in the shared directory of the Vagrant.Isn't that a shared directory by any chance?
Also, I don't know if it's unicorn, but Nodejs had a problem where the socks didn't automatically disappear when listening to the Unix domain socket.Of course, I can't listen if there's any trash left, so if there's a socket of the same name left, please try unlink it.
The path in .sock described on the configuration file side in /etc/nginx/conf.d/ and the path specified in listen in unicorn.rb must be the same.
#'unicorn' part is proxy path
upstream unicorn {
# Match the path here with 'unicorn.rb'
server unix : /var/www/html/unicorn/tmp/sockets/unicorn.sock fail_timeout = 0;
}
server{
location / {
# match the name specified in upstream
proxy_pass http://unicorn;
}
}
Is the setting similar to the one shown in ?
The following article is for sinatra, but the explanation of unicorn and nginx may be helpful.
