Start your rethinkdb instance with this flag:
--bind all
(or bind=all
in the configuration file for your instance)
Block external access to the web UI with these two commands:
sudo iptables -A INPUT -i eth0 -p tcp --dport 8080 -j DROP
sudo iptables -I INPUT -i eth0 -s 127.0.0.1 -p tcp --dport 8080 -j ACCEPT
Install nginx:
sudo apt-get install nginx
Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.
The following steps assume you've got a set-up like mine, where:
This is what the [official documentation][1] says about the terminate/2
callback for a gen_server:
This function is called by a gen_server when it is about to terminate. It should be the opposite of Module:init/1 and do any necessary cleaning up. When it returns, the gen_server terminates with Reason. The return value is ignored.
Reason is a term denoting the stop reason and State is the internal state of the gen_server.
Reason depends on why the gen_server is terminating. If it is because another callback function has returned a stop tuple {stop,..}, Reason will have the value specified in that tuple. If it is due to a failure, Reason is the error reason.
