ROSE Compiler Framework/System Administration

Manual restart processEdit

In case the @reboot cron jobs were not properly saved on [hudson-rose-30], please

  • Start Jenkins
$ ssh hudson-rose@hudson-rose-30
$ cd ~/JENKINS
$ ./start.sh
  • Start Redmine
$ ssh hudson-rose@hudson-rose-30
$ cd ~/opt/redmine
$ ./redmine.sh start

Both scripts should start a screen for each service.

  • Check status
$ screenls
  • Github

Please also ensure that Github is started on [rose-git]. I'd imagine you may have to start the VM again.

Apache TomcatEdit

The Apache Tomcat servlet is run locally on hudson-rose-30.

StartupEdit

startup.sh calls catalina.sh start which sources our custom jenkins-env.sh.

hudson-rose-30 $ /export/tmp.hudson-rose/applications/apache/tomcat/bin/startup.sh

On @rebootEdit

  hudson-rose-30 $ crontab -e
  @reboot /export/tmp.hudson-rose/applications/apache/tomcat/bin/startup.sh

ShutdownEdit

hudson-rose-30 $ /export/tmp.hudson-rose/applications/apache/tomcat/bin/shutdown.sh

BackupEdit

The local installation is synced by Jenkins to the NFS at /home/hudson-rose/Applications/apache/tomcat/.

RubyEdit

RVM (Ruby Version Manager)Edit

Ruby Version Manager (RVM), https://rvm.io/.

1. Download rvm-installer:

  # Download
  $ wget --no-check-certificate https://get.rvm.io
  ...
  Saving to: `rvm-installer'
 
  100%[====================================================================>] 9,439       --.-K/s   in 0s      
 
  2012-07-05 17:09:08 (20.5 MB/s) - `rvm-installer' saved [9439/9439]
 
  # Change permissions to make it executable
  $ chmod +x ./rvm-installer

2. Install RVM to a local user location (i.e. not to a root/sudo location like /usr or /bin):

First, disable the SSL certificate check for cURL, used in the rvm-installer, since it could be a problem when behind a firewall. You can do this step manually (recommended), or using this ad-hoc script:

  $ sed -i 's/curl -/curl --insecure -/g' rvm-installer

Second, set the rvm_path environment variable to specify your installation location (similar to --prefix for Autoconf projects):

  $ export rvm_path=$(pwd)/rvm

Finally, install RVM:

  $ ./rvm-installer

  Installation of RVM in /export/tmp.hudson-rose/opt/ruby/rvm/ is almost complete:
 
    * To start using RVM you need to run `source /export/tmp.hudson-rose/opt/ruby/rvm/scripts/rvm`
      in all your open shell windows, in rare cases you need to reopen all shell windows.
 
  # hudson-rose,
  #
  #   Thank you for using RVM!
  #   I sincerely hope that RVM helps to make your life easier and more enjoyable!!!

3. Use RVM: Now, we can use RVM (as instructed by the above RVM installation message):

  $ source /export/tmp.hudson-rose/opt/ruby/rvm/scripts/rvm

For example,

  [hudson-rose@hudson-rose-31]which rvm
  /export/tmp.hudson-rose/opt/ruby/rvm/bin/rvm

Install Ruby:

# Nothing is installed yet...
[hudson-rose@hudson-rose-31]rvm list
 
rvm rubies
 
# No rvm rubies installed yet. Try 'rvm help install'.
# Check what's available...

GitoliteEdit

Sitaramc's Gitolite software (https://github.com/sitaramc/gitolite/) "allows you to setup git hosting on a central server, with fine-grained access control and many more powerful features." See the documentation for more details.

Here are some benefits of Gitolite-hosted Git repositories compared to filesystem-hosted repositories:

  • Authorized access only: SSH key-pairs for authentication purposes
  • Only Git operations permitted: nobody is allowed to modify the Git repositories on the server (e.g. change permissions, manually manipulate the bare repository's index, etc.). This is achieved by restricting remote commands over SSH using the command keyword in the ${HOME}/.ssh/authorized_keys file of the Gitolite user account on the Gitolite server. See this brief guide for more details.

Note: Gitolite is purely a software tool to host Git repositories. It does not provide code review, issue tracking, a web interface, or repository wikis, etc.
