#################################
#
#  本清单基于 ubuntu 12.04，
#
#  只是一个清单，不是一个可以安全执行的脚本
#
#################################

# create a linode,login as root, and create a common user for all the tasks
ssh root@the_ip_of_this_linode
adduser peter --ingroup sudo
su peter
cd # go to /home/peter


#################################
#
#  PART 1: 这一部分，和我在本地开发机器上搭建开发环境采用的步骤是完全一样的
#  我的开发机器也是 ubuntu 1204，一般我都喜欢保证本地开发环境和 server
#  上部署环境的高度一致。

sudo apt-get -y install git curl

# nice to add ~/.gitconfig before you run the rbenv-installer
# since the installer going to feach from git repos, without the config,
# trouble can happen.

# I see libxslt1.1 libxml things installed here too, that's why gems like nokogiri will produce no error installing
rbenv bootstrap-ubuntu-12-04 # this may require password, also works nicely for 14.04
# 这一步如果不做 rbenv install 也可以成功，不过后面再去使用 gem install xxx 就会报错：zlib can not found

rbenv global 1.9.3-p392

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install -y nodejs

sudo apt-get install -y mysql-client mysql-server libmysqlclient-dev


#################################
#
#  PART 2: 下面是 happycasts 项目部署的具体内容
#  但是本部分的内容依然是服务器和开发机上步骤完全一样
#
#################################

# add ssh key to github, so that you can get a read-write happycasts repo clone
ssh-keygen -t dsa

git clone [email protected]:happypeter/happycasts.git


cd happycasts/
bundle

# for passenger and apache
sudo apt-get install -y apache2 apache2-prefork-dev libcurl4-openssl-dev libaprutil1-dev
gem install passenger
rbenv rehash
passenger-install-apache2-module
# if your RAM is 512M, you may need: https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04
sudo vim /etc/apache2/httpd.conf
# add passenger lines and a virtualhost to http.conf

sudo apachectl graceful


#################################
#
#  PART 3: 产品环境下的一些具体操作
#  和本地开发机器上有较大不同
#
#################################

cd config
cp database.example.yml database.yml # 并在其中添加数据库密码
bundle exec rake db:create RAILS_ENV=production # 这步为我们创建数据库，名为 happycasts_production
touch tmp/restart.txt # need to create this for the first time, since tmp/ is in .gitignore


#################################
#
#  PART 4: 这一部分的内容一般我会放到一个脚本中，放在本地做一键部署
#  https://gist.github.com/happypeter/3634487
#
#################################

bundle exec rake db:migrate RAILS_ENV=production
bundle exec rake assets:precompile
mysql -uroot happycasts_production<happycasts_production.sql


#################################
#
#  PART 5:  一些小工具
#
#################################

sudo apt-get install tig tree ack-grep # make using git，vim things more comfortable on production server
