Pmux gateway is an executor for Pmux (https://github.com/iij/pmux) through HTTP request.

Requirements

Installation

Install dependency programs

gem install gflocator
gem install pmux
gem install eventmachine
gem install em_pessimistic
git clone https://github.com/eventmachine/evma_httpserver.git
cd evma_httpserver
rake gem:build
gem install eventmachine_httpserver-0.2.1.gem
(I do not recommend "gem install eventmachine_httpserver")

Install pmux-gw

gem install pmux-gw

Usage

pmux-gw [-c config] [-F] [-h]
-c : specified config file
-F : foreground mode
-h : print usage

Quick start

Install glusterfs client (http://www.gluster.org/)

CentOS/RHEL

rpm -ivh glusterfs-3.3.1-1.el6.x86_64.rpm
rpm -ivh glusterfs-fuse-3.3.1-1.el6.x86_64.rpm

Create an environment that can use pmux

mkdir /mnt/volume
mount -t glusterfs gfsnode1:volume /mnt/volume
gflocator
useradd -m admin
sudo -u admin ssh-keygen
(copy publickey to glusterfs nodes)

Make sure that the following command will work

sudo -u admin pmux --status -h 127.0.0.1
sudo -u admin pmux --mapper="ls -al" --storage=glusterfs --locator-host=127.0.0.1 /mnt/volume

Create an environment that can use pmux-gw

mkdir /etc/pmux-gw
cp /conf/pmux-gw.conf /etc/pmux-gw/pmux-gw.conf
cp /conf/password /etc/pmux-gw/password
chown -R admin:admin /etc/pmux-gw/password
chmod -R 600 /etc/pmux-gw/password
pmux-gw
curl --basic -u user:pass -iv 'http://127.0.0.1:18080/pmux?mapper=ls&file=/'
