Install RVM system wide on Ubuntu Server

1: Install git if you don't already have it

$ sudo apt-get install git-core

2: Download RVM

$ sudo bash < <( curl -L http://bit.ly/rvm-install-system-wide )

This creates /usr/local/rvm and the group 'rvm'

3: Add each user to group rvm

$ sudo usermod -aG rvm ubuntu

4: Add startup lines to each user's .profile

[[ -s '/usr/local/lib/rvm' ]] && source '/usr/local/lib/rvm'

5: Add this line to /etc/rvmrc (may not be necessary)

$ echo "export rvm_path=/usr/local/rvm" > /etc/rvmrc

6: Use rvm as a user - best to logout/login first to make sure you get all the paths etc setup

$ rvm list
$ rvm package install zlib ( I needed this to get install to work )
$ rvm install 1.9.2 --with-zlib-dir=/usr/local/rvm/usr

To set default ruby version

$rvm --default use 1.9.2

RVM with Ubuntu 10.4

1. install ruby lib:


sudo apt-get install curl git-core bison build-essential zlib1g-dev libssl-dev libreadline6-dev libxml2-dev autoconf libxslt1-dev libpq-dev postgresql


2. install rvm

bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )

3. extra check
mkdir -p ~/.rvm/src/ && cdm ~/.rvm/src && rm -rf ./rvm/ && git clone --depth 1 git://github.com/wayneeseguin/rvm.git && cd rvm && ./install

4. add this line very end of your profile(.bash_profile)

# this is for rvm
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

5. to install ruby 1.9.1

rvm install 1.9.1 ; rvm 1.9.1

gzip -dc ruby-oci8-2.0.4.tar.gz | tar xvf -

Install Oracle 11g R2 on Ubuntu 10.4

I follow the steps from
http://www.pythian.com/news/1355/installing-oracle-11gr1-on-ubuntu-810-intrepid-ibex/

I have to make some adjustments for my Ubuntu 10.4 64 bits, so here are steps:

Copy the unpacked Oracle 11gR1 to the box we’re working on:


luan@luan-laptop:~$ sudo su -
root@luan-laptop:~# mv /home/download/database /media/database
root@luan-laptop:~# chown -R oracle:oinstall /media/database
root@luan-laptop:~#
Now change some system-wide configuration files, starting with /etc/sysctl.conf:

root@luan-laptop:~# cd /etc
root@luan-laptop:/etc# cp sysctl.conf sysctl.conf.original
Edit it, adding the following lines to the bottom of the file:

fs.file-max = 65535
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65535
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
Then, let’s modify /etc/security/limits.conf:

root@luan-laptop:/etc# cd /etc/security/
root@luan-laptop:/etc/security# cp limits.conf limits.conf.original
Add the following lines to the bottom of the file:

oracle soft nproc 2047
oracle hard nproc 16383
oracle soft nofile 1023
oracle hard nofile 65535
The last one, for now, is /etc/pam.d/login:

root@luan-laptop:/etc/security# cd /etc/pam.d
root@luan-laptop:/etc/pam.d# cp login login.original
Edit login, adding to it:

session required /lib/security/pam_limits.so
session required pam_limits.so

Here is how to get display working on my laptop.

oracle@luan-laptop:~$ exit
logout
root@luan-laptop:~# DISPLAY=:0; export DISPLAY; xhost +;
access control disabled, clients can connect from any host
root@luan-laptop:~# su - oracle
oracle@luan-laptop:~$ DISPLAY=:0 ; export DISPLAY
oracle@luan-laptop:~$ xclock
oracle@luan-laptop:~$

oracle@luan-laptop:~$ cd /media/database
oracle@luan-laptop:/media/database$ ./runInstaller -ignoreSysPrereqs

Now the windows installation screen will appear. You should be able to follow the default installation.

he solution was to modify the LD_LIBRARY_PATH to include /usr/local/lib or to where the ruby lib is located.


Modified:

sudo vi .bashrc

#~/.bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

install ruby 1.9.1 script

cd ruby-1.9.1-p$PATCH

install ruby 1.9.1p376 on Ubuntu 9.10

First, remove any ruby version on the system:

sudo apt-get remove --purge ruby1.8 ruby1.9

-- package build dependencies (ruby)

sudo apt-get build-dep ruby1.9

-- get ruby 1.9 source
-- if you can't get it, try to download from
-- http://www.ruby-lang.org/en/

wget -c ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p376.tar.gz

-- extract ruby source using tar

tar -xvzf ruby-1.9.1-p376.tar.gz

-- go to extracted ruby code dir

cd ruby-1.9.1-p376/

-- execute configure
./configure --prefix=/opt/ruby-1.9.1-p376 --enable-shared

-- execute make command
make

-- install process
