I have Ruby 2.1.2 installed and Rails 4.2.
Bundle install runs without error.
I can do a Rails C without error.
Rails s -p3004 launches with webrick or thin without error
When I browse to mytestsite:3004 safari, firefox, and chrome all report “can’t connect to server”
No errors show in any system logs; syslog, lfd.log, auth.log, or any of the apache logs.
If I launch my 4.04 site, ports 3001, 3002 work fine. If I bring down 4.04, and launch 4.2 on port 3001 or 3002, I get the ‘can not connect to server’ error. This seems to mean to me that it’s not a firewall issue blocking the port. Nonetheless, iptables -L reports that port 3004 is open:
ACCEPT tcp -- anywhere anywhere ctstate NEW tcp dpt:3004
=> Booting WEBrick => Rails 4.2.0.beta1 application starting in development on http://localhost:3004 => Run `rails server -h` for more startup options => Ctrl-C to shutdown server [2014-09-02 21:31:06] INFO WEBrick 1.3.1 [2014-09-02 21:31:06] INFO ruby 2.1.1 (2014-02-24) [x86_64-linux] [2014-09-02 21:31:06] INFO WEBrick::HTTPServer#start: pid=4599 port=3004
(same result with thin).
Telnet localhost 3004 works from the server however telnet from another server to the port and ip address results in a connection refused.
and ps reports the program is loaded:
ps aux|grep 3004 user 1062 0.0 0.5 578600 183996 pts/2 Sl+ 20:15 0:03 /home/user/.rvm/rubies/ruby- 2.1.1/bin/ruby bin/rails s -p3004
which is also confirmed by netstat:
netstat -tpln | grep 3004 tcp 0 0 127.0.0.1:3004 0.0.0.0:* LISTEN 1062/ruby
but mmap reports the port is closed:
Starting Nmap 6.40 ( http://nmap.org ) at 2014-09-02 21:33 UTC Nmap scan report for localhost (127.0.0.1) Host is up (0.000059s latency). rDNS record for 127.0.x.1: local_host.local_domain PORT STATE SERVICE 3004/udp closed unknown
And a telnet to the server 3004 reports connection refused.
Like I said, I’d think it was a firewall issue except that changing to port 3001, which I know to work with Rails 4.04, fails with 4.2. Anyone have any suggestions?
WEBrick bound to 127.0.0.1 rather than to INADDR_ANY, so you can only access it via that address. If you want to set what address it binds to, use the
-b option. For example:
rails s -b 0.0.0.0 -p 3004
