Installation GitLab sous Scientific Linux 6.3 (SL6)

Installation GitLab sous Scientific Linux 6.3

Debut d'un billet qui couvre l'installation de gitlab sous scientific linux (globalement EL6)

NOUVEAU BILLET : GITLAB 6 (installation bitnami et script)


Nous allons suivre l'installation en 6 étapes fournie par Gitlab.
Malheureusement, le tutoriel fourni, n'est pas 'compatible' avec scientific linux, d'où ce billet.

Mon script installe la version 5-3 de gitlab et la version 2.0.0-p247 de ruby. Il est également compatible avec la version 5-4 de gitlab, il vous suffit de changer le numéro de version au début du script.

N'oubliez pas de modifier :
servername.com (configuration httpd)
supersecret (mot de passe mysql)

#!/bin/bash
# Installer for GitLab on RHEL 6 (Red Hat Enterprise Linux and CentOS)
#

##Export proxy settings
# or not ...

# Define the public hostname
export GL_HOSTNAME=$HOSTNAME

# Install from this GitLab branch
export GL_GIT_BRANCH="5-3-stable"

# Define the version of ruby the environment that we are installing for
export RUBY_VERSION="2.0.0-p247"

## Install epel-release
yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

# Exit on error

die()
{
  # $1 - the exit code
  # $2 $... - the message string

  retcode=$1
  shift
  printf >&2 "%s\n" "$@"
  exit $retcode
}

echo "### Check OS (we check if the kernel release contains el6)"
uname -r | grep "el6" || die 1 "Not RHEL or CentOS 6 (el6)"

# Ruby
## packages (from rvm install message):
yum -y install patch gcc-c++ readline-devel zlib-devel libffi-devel openssl-devel make autoconf automake libtool bison libxml2-devel libxslt-devel libyaml-devel

## Install rvm (instructions from https://rvm.io)
curl -L get.rvm.io | bash -s stable

## Load RVM
source /etc/profile.d/rvm.sh

## Fix for missing psych
## *It seems your ruby installation is missing psych (for YAML output).
## *To eliminate this warning, please install libyaml and reinstall your ruby.
## Run rvm pkg and add --with-libyaml-dir
rvm pkg install libyaml

## Install Ruby (use command to force non-interactive mode)
command rvm install $RUBY_VERSION --with-libyaml-dir=/usr/local/rvm/usr
rvm --default use $RUBY_VERSION

## Install core gems
gem install bundler


## Create a git user for Gitlab
adduser --system --shell /bin/bash --create-home --comment 'GitLab' git

service mysqld start

# Create a user for GitLab. (change supersecret to a real password)
echo "CREATE USER 'gitlab'@'localhost' IDENTIFIED BY 'supersecret';" | mysql -u root

### Create the database
echo "CREATE DATABASE IF NOT EXISTS gitlabhq_production DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;" | mysql -u root


# Grant the GitLab user necessary permissopns on the table.
echo "GRANT SELECT,LOCK TABLES,INSERT,UPDATE,DELETE,CREATE,DROP,INDEX,ALTER ON gitlabhq_production.* TO 'gitlab'@'localhost';"\
| mysql -u root

# workers 3 # if you have at least 2 GB RAM
# workers 4 # if you have at least 2.5 GB RAM

# === Puma control rack application ===

# Start the puma control rack application on “url”. This application can
# be communicated with to control the main server. Additionally, you can
# provide an authentication token, so all requests to the control server
# will need to include that token as a query parameter. This allows for
# simple authentication.

gem install charlock_holmes --version '0.6.9.4'

## For MySQL
cd /home/git/gitlab/

# Force it to be silent (issue 31)
export force=yes

## Install init script
curl https://raw.github.com/gitlabhq/gitlab-recipes/master/init.d/gitlab-centos > /etc/init.d/gitlab
chmod +x /etc/init.d/gitlab

## Fix for issue 30
# bundle not in path (edit init-script).
# Add after ". /etc/rc.d/init.d/functions" (row 17).
sed -i "17 a source /etc/profile.d/rvm.sh\nrvm use $RUBY_VERSION" /etc/init.d/gitlab

chkconfig --add gitlab

chkconfig gitlab on
