## Ruby
|
||||
|
||||
Ruby versions packaged in official repositories are not suitable to work with consul (at least Debian 7 and 8), so we'll have to install it manually.
|
||||
The preferred method is via rvm:<br/>
|
||||
**be careful as only the multi user option installs all dependencies automatically, as we use 'sudo'.**

The preferred method is via rvm:

|

(only the multi user option installs all dependencies automatically, as we use 'sudo'.)

###as local user:
|
||||
|
||||
```
|
||||
$ curl -L https://get.rvm.io | bash -s stable
|
||||
curl -L https://get.rvm.io | bash -s stable
|
||||
```
|
||||
###for all system users
|
||||
|
||||
```
|
||||
$ curl -L https://get.rvm.io | sudo bash -s stable
|
||||
curl -L https://get.rvm.io | sudo bash -s stable
|
||||
```
|
||||
|
||||
and then add your user to rvm group
|
||||
|
||||
```
|
||||
$ sudo usermod -a -G rvm <user>
|
||||
sudo usermod -a -G rvm <user>
|
||||
```
|
||||
|
||||
and finally, add rvm script source to user's bash (~/.bashrc) (this step it's only necessary if you still can't execute rvm command)
|
||||
|
||||
```
|
||||
[[ -s /usr/local/rvm/scripts/rvm ]] && source /usr/local/rvm/scripts/rvm

rvm install 2.3.0

## PostgreSQL (>=9.4)
|
||||
|
||||
PostgreSQL version 9.4 is not official in debian 7 (wheezy), in 8 it seems to be officially maintained.
|
||||
|
||||
So you have to add a repository, the official postgresql works fine.
|
||||
|
||||
Add the repository to apt, for example creating file */etc/apt/sources.list.d/pgdg.list* with:
|
||||
|
||||
```
|
||||
deb http://apt.postgresql.org/pub/repos/apt/ wheezy-pgdg main
|
||||
```
|
||||
|
||||
afterwards you'll have to download the key, and install it, by:
|
||||
|
||||
```
|
||||
wget https://www.postgresql.org/media/keys/ACCC4CF8.asc
|
||||
apt-key add ACCC4CF8.asc
|
||||
```
|
||||

||||
and install postgresql

Perhaps it's needed to create a superuser rol with password in postgresql, and write it in */config/database.yml* 'user:' and 'password:' fields.
|
||||
|
||||
Also, it seems that postgresql use as default an unix socket for localhost communications. If we encounter problems creating database (connection problems) we can change in */config/database.yml* the line:
