Creating your own **m2r** Amazon cloud server
=============================================
EC2
---
Begin by getting your own [Amazon EC2](https://aws.amazon.com/ec2/) instance running. For an operating system, any Unix-alike should work; we used the [Amazon Linux AMI](https://aws.amazon.com/amazon-linux-ami/). If you prefer not to use a cloud server and would rather use a physical machine, in principle all that follows should work in the same way, though this has not been tested.
### Setting up the server
Once you have spun your EC2 instance, log into it and run the following commands that download the m2rserver python script:
``` bash
mkdir m2rserver
cd m2rserver
curl https://raw.githubusercontent.com/coneill-math/m2r/master/inst/server/m2rserver.py > m2rserver.py
echo 'cd /home/ec2-user/m2rserver; python m2rserver.py' >> /etc/rc.local
```
<!-- Using your favorite text editor, in the file `/etc/rc.local`, add the -->
<!-- following line -->
<!-- ```{bash eval=FALSE} -->
<!-- cd /home/ec2-user/m2rserver; python m2rserver.py -->
<!-- ``` -->
The last line will cause the server to start when the system boots. Reboot the instance, and the python script will start listening for a connection.
Next, install [docker](https://www.docker.com) on your machine. Your method of doing this will depend on what distribution you use. For the Amazon Linux AMI, [yum](https://en.wikipedia.org/wiki/Yellowdog_Updater,_Modified) should work, see instructions [here](https://docs.docker.com/engine/installation/linux/centos/). Once docker has been installed, run
``` bash
docker pull sommars/m2r
```
to install our docker image on your machine. As of June 2017, the image comes provisioned with [Macaulay2](http://www.math.uiuc.edu/Macaulay2/), [PHCpack](http://homepages.math.uic.edu/~jan/download.html), [Bertini](https://bertini.nd.edu), [4ti2](http://www.4ti2.de), and [LattE](https://www.math.ucdavis.edu/~latte/).
### Local changes
When you use **m2r**, after loading the package, each time you must run the command
``` r
start_m2(cloud = TRUE, hostname = "host.uri.com")
```
to initialize a connection to your new host.
