Deployment on RELS/CentOS

Prepare environment

First of all we should add new users.

Add new users rosa, git and add necessary groups:

sudo useradd rosa && sudo passwd rosa
sudo useradd git && sudo usermod -a -G rosa git && sudo usermod -a -G git rosa

Add admin rights for user rosa (update /etc/sudoers file):

Install nesessary packages

sudo yum install -y git-core libicu-devel gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel postgresql-devel nginx postfix python-devel crontabs openssl

Install RVM (for git and rosa users):

To install RVM type in this command:

curl -L get.rvm.io | bash -s stable

After it is done installing, load RVM.

source ~/.rvm/scripts/rvm

In order to work, RVM has some of its own dependancies that need to be installed.

rvm requirements

Install Ruby (for git and rosa users):

Once you are using RVM, installing Ruby is easy.

rvm install ruby-2.1.3

Ruby is now installed. However, since we accessed it through a program that has a variety of Ruby versions, we need to tell the system to use 2.1.3 by default.

rvm use ruby-2.1.3 --default

Install RubyGems (for git and rosa users):

The next step makes sure that we have all the required components of Ruby on Rails. We can continue to use RVM to install gems; type this line into terminal.

rvm rubygems current

Install PostgreSQL

See solution by installation: Install PostgreSQL

The next step updates .bashrc file:

PATH=/usr/pgsql-9.2/bin:$PATH

Prepare server to deployment

Create folders for web:

sudo mkdir /srv && sudo chown -R rosa:rosa /srv && mkdir -p /srv/rosa_build/shared/tmp

Start services on Boot

sudo chkconfig --levels 2345 nginx on
sudo chkconfig crond on
sudo service crond start

Configure ssh access for git and rosa users

sudo mkdir -p /home/{rosa,git}/.ssh && sudo touch /home/{rosa,git}/.ssh/authorized_keys &&
sudo chmod 600 /home/{rosa,git}/.ssh/authorized_keys &&
sudo chown -R rosa:rosa /home/rosa && sudo chown -R git:git /home/git

Add Your public key into ~rosa/.ssh/authorized_keys

Configure PostgreSQL

Change to postgres user

sudo su postgres

Create new user

createuser -D -P -E -e rosa
Enter password for new role: rosa
Enter it again: rosa
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n

Create database

createdb -O rosa -e rosa_build

Configure Git

From rosa user

git config --global user.name Rosa
git config --global user.email rosa@abf.rosalinux.ru

Solution for showing filenames with Cyrillic alphabet

git config --global core.quotepath false

Configure Redis DB

See solution by installation: Install Redis DB

wget https://abf.rosalinux.ru/abf/abf-configs/raw/master/rhel/redis_install.sh
chmod +x redis_install.sh
sudo ./redis_install.sh

Configure Nginx

If You have SSL certificates which not self signed You can add their for nginx:

/etc/ssl/abf.key
/etc/ssl/abf.crt

Solution for creating self signed SSL Certificate on nginx: How to Create a SSL Certificate. But no warranty for correct working of all system.

Configuration files for nginx:

cd /etc/nginx/
sudo curl -L -O https://abf.rosalinux.ru/abf/abf-configs/raw/master/nginx/nginx.conf
cd /etc/nginx/conf.d/

without SSL certificates:

sudo curl -L -O https://abf.rosalinux.ru/abf/abf-configs/raw/master/nginx/rosa_build.http.conf
sudo mv rosa_build.http.conf rosa_build.conf

with SSL certificates:

sudo curl -L -O https://abf.rosalinux.ru/abf/abf-configs/raw/master/nginx/rosa_build.https.conf
sudo mv rosa_build.https.conf rosa_build.conf

Then restart nginx:

sudo service nginx restart

Configure iptables

Update /etc/sysconfig/iptables file:

Then restart iptables:

sudo service iptables restart

Configure ssh access for git

sudo su - git
env GIT_SSL_NO_VERIFY=true git clone https://abf.rosalinux.ru/abf/gitlab-shell.git
cp gitlab-shell/config.yml.example gitlab-shell/config.yml

Update config.yml as You like:

# GitLab user. git by default
user: git

# Url to gitlab instance. Used for api calls
# Use http instead of https when no ssl certificates
gitlab_url: "https://127.0.0.1/"

# Repositories path (APP_CONFIG[‘git_path’] + ‘/git_projects’)
repos_path: "/home/rosa/gitstore/git_projects"

Archivation of Logs

sudo vi /etc/logrotate.d/redis

/var/log/redis_*.log {
   weekly
   rotate 10
   copytruncate
   delaycompress
   compress
   notifempty
   missingok
}

sudo vi /etc/logrotate.d/rosa_build

/srv/rosa_build/shared/log/*.log {
  weekly
  missingok
  rotate 52
  compress
  delaycompress
  notifempty
  copytruncate
}

Startup ABF

On DEV machine:

cap production deploy:setup
cap production deploy:check
cap production deploy:update

On server:

cd /srv/rosa_build/current && RAILS_ENV=production bundle exec rake db:seed

Update all configuration files:

/srv/rosa_build/shared/config/application.yml
/srv/rosa_build/shared/config/newrelic.yml

Startup:

cap production deploy:start
