I am using RVM ruby, and crontab doesn't work properly.
crontab doesn't look at .bashrc or .bash_profile. Therefore, we have to add this into
sudo vi /etc/profile. Just source whatever in profile.
luan@luan-laptop:/etc$ head profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
# luan added here
source /home/luan/.bash_profile
# end luan added
if [ -d /etc/profile.d ]; then

SSH without enter password
Step 1 of 2 : On local machine: Generate Authentication Keys
$ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/luan/.ssh/id_rsa):
Accept the default choice. Hit enter.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Hit enter twice. A passphrase encrypts your private key so that no one can see it. However, you should NOT encrypt your private key if you want a password-less login.
The key fingerprint is:
5e:26:52:34:a1:22:18:68:11:11:7d:8d:c6:d5:4b:bf luan@luan.com
What just happened?
On your local server you just created 2 files in your ~/.ssh directory.
cd ~/.ssh
ls -l
-rw------- 1 luan luan 1675 2011-01-27 17:27 id_rsa
-rw-r--r-- 1 luan luan 411 2011-01-27 17:27 id_rsa.pub
id_rsa contains your private key. id_rsa.pub contains your public key.
Step 2 of 2 : On remote machine: authorize password less login
Login to remote machine
$ssh hostname -l username
The authenticity of host 'luan.com (XXX.XXX.XXX.XX)' can't be established.
RSA key fingerprint is 44.2b:93:ce:1b:1b:99:3a:6d:91:d1:50:aa:0d:87:40.
Are you sure you want to continue connecting (yes/no)?
Type yes and hit enter.
Warning: Permanently added 'luan.com,XXX.XXX.XXX.XX' (RSA) to the list of known hosts.
username@luan.com's password:
Enter your password, and hit enter.
Create a .ssh directory on the remote machine and create a .authorized_keys file in that directory. You need to copy the entire contents of your local machine’s ‘id_rsa.pub’ and paste it in the .authorized_keys file on the remote server.
$mkdir -p .ssh
$chmod 700 .ssh
$cd .ssh
$touch authorized_keys
$chmod 600 authorized_keys
$vi authorized_keys
# copy-paste the entire contents of your local machine's ~/.ssh/id_rsa.pub file in authorized_keys
# logout
exit
Important: Make sure you have the right permissions for .ssh directory and authorized_keys file, as shown in chmod command above otherwise SSH will not honor your authorized_keys.
You should now be able to login to the remote server without typing your password.
# type this command from your local machine
$ssh hostname -l username
SSH should log you in without password! Now, you can also scp or rsync (over ssh) without having to enter your password.
$ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/luan/.ssh/id_rsa):
Accept the default choice. Hit enter.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Hit enter twice. A passphrase encrypts your private key so that no one can see it. However, you should NOT encrypt your private key if you want a password-less login.
The key fingerprint is:
5e:26:52:34:a1:22:18:68:11:11:7d:8d:c6:d5:4b:bf luan@luan.com
What just happened?
On your local server you just created 2 files in your ~/.ssh directory.
cd ~/.ssh
ls -l
-rw------- 1 luan luan 1675 2011-01-27 17:27 id_rsa
-rw-r--r-- 1 luan luan 411 2011-01-27 17:27 id_rsa.pub
id_rsa contains your private key. id_rsa.pub contains your public key.
Step 2 of 2 : On remote machine: authorize password less login
Login to remote machine
$ssh hostname -l username
The authenticity of host 'luan.com (XXX.XXX.XXX.XX)' can't be established.
RSA key fingerprint is 44.2b:93:ce:1b:1b:99:3a:6d:91:d1:50:aa:0d:87:40.
Are you sure you want to continue connecting (yes/no)?
Type yes and hit enter.
Warning: Permanently added 'luan.com,XXX.XXX.XXX.XX' (RSA) to the list of known hosts.
username@luan.com's password:
Enter your password, and hit enter.
Create a .ssh directory on the remote machine and create a .authorized_keys file in that directory. You need to copy the entire contents of your local machine’s ‘id_rsa.pub’ and paste it in the .authorized_keys file on the remote server.
$mkdir -p .ssh
$chmod 700 .ssh
$cd .ssh
$touch authorized_keys
$chmod 600 authorized_keys
$vi authorized_keys
# copy-paste the entire contents of your local machine's ~/.ssh/id_rsa.pub file in authorized_keys
# logout
exit
Important: Make sure you have the right permissions for .ssh directory and authorized_keys file, as shown in chmod command above otherwise SSH will not honor your authorized_keys.
You should now be able to login to the remote server without typing your password.
# type this command from your local machine
$ssh hostname -l username
SSH should log you in without password! Now, you can also scp or rsync (over ssh) without having to enter your password.

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
$ 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

Install ruby 1.9 on Ubuntu 9.04
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

wget -c ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p0.tar.gz
-- extract ruby source using tar
tar -xvzf ruby-1.9.1-p0.tar.gz
-- go to extracted ruby code dir
cd ruby-1.9.1-p0/
-- execute configure
./configure --prefix=/opt/ruby-1.9.1-p0 --enable-pthread --enable-shared
-- execute make command
make
