### install bundler and rails
gem install bundler
gem install rails

### install dep-packages
yum -y update
yum -y install wget curl gcc libxml2-devel libxslt-devel make openssh-server libyaml-devel postfix libicu-devel libcurl-devel libcurl readline-devel readline glibc glibc-devel openssl-devel openssl mysql++-devel postgresql-devel zlib-devel git
yum -y install redis
yum -y install mysql-devel mysql-server mysql
yum -y install nginx

chkconfig nginx on
chkconfig mysqld on
chkconfig redis on

### start redis server
### otherwise the `Background Jobs` page says "Internal Server Error"
service redis start

### mysql
service mysqld start
/usr/bin/mysql_secure_installation
# - manually set password for root of mysql

### add user
mysql -u root -p
CREATE DATABASE IF NOT EXISTS `gitlab_ci_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
CREATE USER 'gitlab_ci'@'localhost' IDENTIFIED BY '${PASSWORD}';
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlab_ci_production`.* TO 'gitlab_ci'@'localhost';

### user gitlab_ci
useradd --comment 'GitLab CI' -m gitlab_ci

### get gitlab-ci
cd /home/gitlab_ci/
git clone https://github.com/gitlabhq/gitlab-ci.git
cd gitlab-ci

### prepare
git checkout 2-2-stable
mkdir -p tmp/pids
mkdir -p tmp/sockets
chmod -R 755 tmp/

### AGAIN for chinese users.
### modify Gemfile.
### change the first line `source ...` into
### `source 'http://ruby.taobao.org/'`
vim Gemfile

### install
bundle --without development test

### database config
cp config/database.yml.mysql config/database.yml
vim config/database.yml
# - change the username and password for mysql user gitlab_ci

bundle exec rake db:setup RAILS_ENV=production

### install crontab job for user gitlab_ci
su gitlab_ci
bundle exec whenever -w RAILS_ENV=production
exit

### the service script
### ### ATTENSION ###
### gitlab-ci must start up after mysql and redis
### 
### so if you found gitlab_ci service starts BEFORE mysql or redis.
### please check mysql and redis service and change the start order of service gitlab_ci
###
### for example, insert this in startup script to the second line:
### `# chkconfig: - 70 30`
###
### then `chkconfig --del gitlab_ci; chkconfig -add gitlab_ci`

wget https://raw.github.com/gitlabhq/gitlab-ci/2-2-stable/lib/support/init.d/gitlab_ci -P /etc/init.d/
chmod +x /etc/init.d/gitlab_ci
chkconfig gitlab_ci on

### give the permissions back to user gitlab_ci
chown -R gitlab_ci:gitlab_ci /home/gitlab_ci

### nginx config
cd /etc/nginx
mkdir sites-available sites-enabled
sudo wget https://raw.github.com/gitlabhq/gitlab-ci/2-2-stable/lib/support/nginx/gitlab_ci -P /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/gitlab_ci /etc/nginx/sites-enabled/gitlab_ci
vim /etc/nginx/sites-available/gitlab_ci
# - change the server_name of this server
# - dont forget delete default_server after `listen 80`
service nginx start

### disable user gitlab_ci login
usermod -s /sbin/nologin gitlab_ci

### make sure user `gitlab_ci` can execute commands by sudo without tty started
### because the init.d script needs `sudo -u gitlab_ci ...` to launch
### replace `Defaults    requiretty` by this line in file `/etc/sudoers`:
### `Defaults:gitlab_ci !requiretty`
visudo

### done!
### use this account and password to login:
### admin@local.host
### 5iveL!fe
