Rails服务器无法启动

Question

`start_tcp_server': no acceptor (port is in use or requires root privileges) (RuntimeError)

I can confirm that this is a not a port issue. It happened after I changed by /etc/hosts file to use my custom domain name pointing to 127.0.0.1 but after I changed that rails server is not starting in any port.

The command I am using to star: rvmsudo rails s -p 80

Here is how my etc/hosts file look like

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       platform.adwyze.com
255.255.255.255 broadcasthost 
::1             platform.adwyze.com

Answer 1

Usually rails server being started by rails s or rails s -p 5000 . I guess it should not being started in 80 port. Try to start it by these commands instead rails s -p 80

UPDATE : You can find and kill after process that using 3000 by:

lsof -i :3000

kill -9 found_pid

Also it's possible to run the server by bundle exec rails server -b 0.0.0.0 -p 3001

Answer 2

尝试做sudo rails server -p 80 ，如果platform.adwyze.com在https上，请在chrome地址栏上将https更改为http，然后platform.adwyze.com将指向您的本地服务器。
