RVM - Error when try to install RVM in CentOS 6.8

Question

I'm with the following problem:

I'm trying to install RVM in the CenteOS 6.8 in the company that I work. When I try to install it on my local machine, everything goes ok. However, when I try to do the same in a CenteOS 6.8 server machine to create the test environment, to the Quality Analyst to test, the curl command didn't work.

Here is how I tried to install it

$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

gpg: no ultimately trusted keys found
gpg: Total number processed: 2
gpg:               imported: 2  (RSA: 2)

After that, I tried to install RVM with curl like that:

$ \curl -sSL https://get.rvm.io | bash -s stable

After a while, I got:

$ \curl -sSL https://get.rvm.io | bash -s stable


curl: (35) SSL connect error

I had tried tons of option that I found here in the StackOverflow and in the Google but until now, I didn't succeed

Could someone help me, please?

@widjajayd, thanks for the help. I tried to do the sequence bellow, but it stopped in the curl command again.

yum install git 
git config --global user.name "your name "
git config --global user.email "your email "
cd ~/.ssh
ssh-keygen -t rsa -C “your email”
curl -L https://get.rvm.io | bash -s

The 'cd ~/.ssh' did not work because it does not exist. So, I created it and inside of it, I run ''ssh-keygen -t rsa -C “your email”.

In the end, I executed the command curl command and I got:

$ curl -L https://get.rvm.io | bash -s
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
194   194  194   194    0     0    222      0 --:--:-- --:--:-- --:--:--  1405
curl: (35) SSL connect error

I had used this command before I attempted this last curl command. However, the result was the same as above.

Answer 1

An easy way to install it is to do its offline installation.

Just follow the steps in the RVM website:

https://rvm.io/rvm/offline

It will explain how to download the RVM in a different way, plus how to install it with this downloaded file.

Answer 2

probably in you local machine you already set ssl correctly but in your production you not set ssl,

below some step by step for you to double check in centos

yum install git 
git config --global user.name "your name "
git config --global user.email "your email "
cd ~/.ssh
ssh-keygen -t rsa -C “your email”
curl -L https://get.rvm.io | bash -s

To start using RVM you need to run source

source /etc/profile.d/rvm.sh
test rvm -v
