- Generate keys on local machine in using
$ ssh-keygen -t rsa(preferably in~/.ssh). - Check whether your
deployuser on server has~/.sshfolder created. If not, create it. - Still on local machine:
scpyourid_rsa.pubtouser@server:~/.ssh/authorized_keys
Now you should be able to login without password.
- Now edit file
/etc/ssh/sshd_configto disable password authentication:
Change lines:
PermitRootLogin no
PubkeyAuthentication yes
AuthorizedKeysFile %h/.ssh/authorized_keys
PasswordAuthentication no
TCPKeepAlive yes
ClientAliveInterval 60
ClientAliveCountMax 10
UsePAM no
Reload ssh service on server using # service ssh reload.
Change your local ~/.ssh/config by adding following:
Host server
HostName <ip_address>
User <user>
IdentityFile ~/.ssh/id_rsa.pub
Now login as new user ssh server.
This took less than 20s on my server :).

As deploy:
Note: put rbenv scripts into .zshenv; this way they will be available in all shells.
- Install rbenv using guide github.
- Install rbenv-build using guide github.
$ $(SHELL) -l$ rbenv rehash
As deploy in ~:
$ rbenv install -l
$ rbenv install <version>
$ rbenv rehash
$ rbenv local <version> && rbenv global <version> && rbenv shell <version>
As deploy in ~:
gem list passenger --remote$ gem install passenger$ sudo which passenger-install-nginx-module- Install Ubuntu service for passenger using github.
As deploy in ~:
- Add
deployuser towww-datagrou by editing/etc/group. # mkdir -p /var/www/default# chown -R www-data:www-data /var/www# chmod -R g+w /var/www$ echo 'it works' > /var/www/default/index.html
Add default Nginx virtualhost (/opt/nginx/config/nginx.conf):
server {
listen 80 default;
server_name <server_name>;
root /var/www/default;
}
And edit /etc/hosts on local computer:
<server_ip> <server_name>
And test from local computer $ curl <server-name>. You should get it works response.
As deploy in ~:
$ gem install rails$ rbenv rehash
As deploy in /var/www create and test new rails application:
- Test using
rails new test.rails. cdinto new app and uncommenttherubyracerline inGemfile.bundle install$ rails generate controller hello index- Edit
config/routes.rb, add lineroot 'hello#index'.
Add nginx virtualhost, and reload nginx (sudo service nginx reload).
server {
listen 80;
server_name test.rails;
root /var/www/test.rails/public;
passenger_enabled on;
}
And add local computer hosts entry (/etc/hosts).
<server_ip> test.rails
Test using $ curl 'test.rails' from local machine. You should receive couple of HTML lines of your new app.
Install database and create deploy user.
# apt-get install postgresql libpq-dev
# su postgres
$ createuser deploy [n/y/n]
- Edit
/etc/postgresql/9.1/main/postgresql.conf, uncommentlisten_addresses = 'localhost'line. - Edit
/etc/postgresql/9.1/main/pg_hba.conf
Change lines (change localhosts to trust):
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
