edit apache config file

vi /etc/httpd/conf/httpd.conf

and make apache run as backuppc user

User backuppc

edit BackupPC apache config

Jenkins Xvfb in Centos 6

During my last adventures with Jenkins y suffered into a new problem trying to running my gtester’s test battery.

 [exec] TEST: tests/stkmngtest... (pid=13754)
     [exec]
     [exec] Gtk-WARNING **: cannot open display:
     [exec] aborting...
     [exec] FAIL: tests/stkmngtest

that makes my test suite were aborted  and also makes Jenkins useless, and useless things are my competitors because the only useless thing allowed at home is me 😛 .

The basic problem is that there no are a XOrg session running, first I change runlevel to 5 and expect see test runing  a big FAIL was the result.

after reading a bit of literature I discover a thing called Xvfb

for install follow these steps

su

yum install Xvfb

yum install mesa-dri-drivers

the next step was try to install Xvfb plugin in jenkins but i doesn’t work it give these exception

FATAL: null
java.lang.NullPointerException
	at org.jenkinsci.plugins.xvfb.XvfbBuildWrapper.decorateLauncher(XvfbBuildWrapper.java:165)
	at hudson.model.AbstractBuild$AbstractRunner.createLauncher(AbstractBuild.java:525)

	at hudson.model.ResourceController.execute(ResourceController.java:88)
	at hudson.model.Executor.run(Executor.java:239)

I found a quick and dirty solution that is put a xvfb-run call in commands that need a xserver like this

<target name=”runtest” description=”run glib test”>
<exec executable=”xvfb-run”>
<arg value=”gtester”/>
<arg value=”tests/stkmngtest”/>
<arg value=”–keep-going”/>
<arg value=”-o=Tests.xml”/>
</exec>
</target>

the solution for solve these problem is configure Jenkins plugin BIG BIG BIG THANKS TO Tomasz Wysocki, he show me the missing configuration options.

Here for global settings

And here for project settings

When you install Jenkins from the repos one problem is configure ssh keys for jenkins user, the first thing to configure ssh keys was su jenkins and run ssh keygen but it failed because i can’t log with Jenkins user.

i open a terminal as root on server machine as root and start writing:

vim /etc/passwd

changing jenkins line

jenkins:x:492:486:Jenkins Continuous Build server:/var/lib/jenkins:/bin/false

for

jenkins:x:492:486:Jenkins Continuous Build server:/var/lib/jenkins:/bin/bash

after changuing this line you can do

su jenkins

cd

ssh-keygen

cat .ssh/id_rsa.pub

now you have the key for your jenkins user and it can pull from your repos

for more security edit again /etc/passwd and pul false in jenkins shell

jenkins:x:492:486:Jenkins Continuous Build server:/var/lib/jenkins:/bin/false

Installing GitLab 2.1 on Centos 6

gitlab logo

Step 1: Install needed packages

you will need remove installed ruby because repo version is 1.8.7 and we need 1.9 at least

yum remove ruby

yum install wget

enable epel repos

wget

rpm -Uvh epel-release-6-5.noarch.rpm

install required libraries

yum install readline-devel  libyaml-devel gdbm-devel  ncurses-devel  redis openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel  tk-devel  libxml2-devel libffi-devel libxslt-devel libicu-devel httpd httpd-devel gitolite git-all python-devel python-pip sqlite-devel sendmail vim mysql-devel

Step 2: Install Ruby 1.9.3

wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p0.tar.gz

tar xzvf ruby-1.9.3-p0.tar.gz

cd ruby-1.9.3-p0

./configure

make

make install

Step 3: Install gitolite

Create gitolite-admin user

    useradd -d /home/gitolite-admin gitolite-admin

generate RSA key pair for gitolite-admin user

su gitolite-admin
ssh-keygen
exit

Move generate public key to gitolite home dir

cp /home/gitolite-admin/.ssh/id_rsa.pub /var/lib/gitolite/id_rsa_gitolite_admin.pub
chown gitolite:gitolite /var/lib/gitolite/id_rsa_gitolite_admin.pub

complete gitolite and gitolite-admin users pairing

su gitolite
gl-setup /var/lib/gitolite/id_rsa_gitolite_admin.pub

a editor will opened changue repo permissions to 0007

$REPO_UMASK to 0007
exit
su gitolite-admin
cd
git clone gitolite@localhost:gitolite-admin

in the last command you clone the gitolite-admin repo on gitolite-admin’s home. Gitolite-admin repo is gitolite config

before continue we need configure gitolite-admin git profile

git config –global user.email “gitolite-admin@localhost”
git config –global user.name “gitolite-admin”
exit

add gitolite-admin to gitolite group

usermod -a -G gitolite gitolite-admin

changue gitolite-admin password

passwd gitolite-admin

Step 6 Launch Redis

chkconfig redis on

/etc/init.d/redis start

Step 7 GitLab

Clone GitLab sourcecode

cd /var/www

git clone git://github.com/gitlabhq/gitlabhq.git

chown -R gitolite-admin:gitolite-admin gitlabhq/

cd gitlabhq/

Install phython dependencies

pip-python install pygments

Install required gems

gem install bundler

bundle install

su gitolite-admin

bundle install

Prepare config files

cp config/database.yml.example config/database.yml

cp config/gitlab.yml.example config/gitlab.yml

Prepare production enviroment

RAILS_ENV=production rake db:setup
RAILS_ENV=production rake db:seed_fu

you will get these login data

login………admin@local.host
password……5iveL!fe

Config gitolite gitlab link

vim config/gitlab.yml

your  git_host: section must be like this

# Git Hosting congiguration
git_host:
system: gitolite
admin_uri: gitolite@localhost:gitolite-admin
base_path: /var/lib/gitolite/repositories/
host: localhost
git_user: gitolite
# port: 22

fix gitolite permissions

chmod -R 770 /var/lib/gitolite/repositories/

try your installation launching webrick

bundle exec rails s -e production

open a web broser, write  yourhost:3000 and check if everything is working if you get an error send me a comment

Step 2: Enable services at boot-time
apache server
chkconfig httpd on

mysql server
chkconfig mysqld on

Step 3: Open needed ports

open /etc/sysconfig/iptables in your config file and add these rules

-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

-A INPUT -m state –state NEW -m tcp -p tcp –dport 3000 -j ACCEPT

Step 4: Install ruby libs
gem install rails -v=2.3.5
gem install rack -v=1.0.1
gem install mysql
gem install -v=0.4.2 i18n
gem install passenger

Step 5: Download redmine
wget http://rubyforge.org/frs/download.php/74419/redmine-1.1.2.tar.gz

step 6: add redmine user

groupadd redmine
useradd -g redmine redmine
passwd redmine

step 7: decompress redmine
tar -xzvf redmine-1.1.2.tar.gz

step 8: move to destination dir
cd <dest_dir>

step 9: copy redmine
cp -R <redmine_uncompress_dir>/* ./

Step 10: create a new database and a new username in mysql

step 11: configure redmine
cd config/
mv database.yml.example database.yml
open database.yml #complete the data needed
cd ..

step 12: generate session store secret
rake generate_session_store

step 13: generate database structure
RAILS_ENV=production rake db:migrate

step 14: generate default configuration
RAILS_ENV=production rake redmine:load_default_data

step 15 Setting up permissions
mkdir tmp public/plugin_assets #in case of the dirs doesn’t exists
sudo chown -R redmine:redmine files log tmp public/plugin_assets # change redmine:redmine if you create a diferent user
sudo chmod -R 755 files log tmp public/plugin_assets

step 16 check redmine installation
ruby script/server webrick -e production
open in your browser :3000
login is admin pass is admin too

step 17 enable mod_cgi in apache
check in /etc/httpd/conf/httpd.conf if exist the line
LoadModule cgi_module modules/mod_cgi.so

step 18 create public/dispatch.cgi file
mv public/dispatch.cgi.example public/dispatch.cgi
edit the first line
from
#!/usr/bin/env ruby

step 20 grant apache permissions
chown -R apache:apache files log tmp vendor

step 21 set production state in file config/environment.rb
uncoment the line ENV[‘RAILS_ENV’] ||= ‘production’

step 22 configure passenger
passenger-install-apache2-module and follow instructions

if you get an error check this http://stackoverflow.com/questions/5585583/problem-in-installing-passenger
In fact, just need to edit the ” /usr/lib/ruby/gems/1.8/gems/passenger-3.0.6/lib/phusion_passenger/platform_info/apache.rb” file, and replace “test_exe_outdir” with “tmpexedir”.

step 23 Enable cgi in SeLinux
setsebool -P httpd_enable_cgi 1

step 24 add virtual host in apache config file
ServerName redmine..com
ServerAdmin webmaster@.com
DocumentRoot /live/redmine/public/
ErrorLog logs/redmine_error_log
Options Indexes ExecCGI FollowSymLinks
Order allow,deny
Allow from all
AllowOverride all

Step 25: close 3000 port editing /etc/sysconfig/iptables file

-A INPUT -m state –state NEW -m tcp -p tcp –dport 3000 -j ACCEPT

Step 26: reboot or restart services
