Ubuntu 16.04 Installation to have a DrawMGT Vagrant Box

OS Installation and Configuration

The basic Ubuntu installation is taken from the Official Ubuntu 16.04 daily Cloud Image amd64 at 2116-10-13.

Adding Virtual Machine Box

Add and start the new virtual machine box to the initialized Vagrant environment:

• $ su - vagrant
  $ cd boxes
  $ wget https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-vagrant.box
  $ vagrant box add xenial64_base ~/boxes/xenial-server-cloudimg-amd64-vagrant.box
  $ mkdir vms/ubuntu16
  $ cd vms/ubuntu16
  $ vagrant init xenial64_base
  $ vagrant up

Login into the VM and Change Passwords

As default the root password is not known and vagrant password is 'vagrant' on the VM box dowloaded from Vagrant. They should be changed:

• $ vagrant ssh
  ubuntu@ubuntu16:~$ passwd
  ubuntu@ubuntu16:~$ sudo bash
  root@ubuntu16:~# passwd

Install development tools and additional packages

It is possible to install the LAMP server (Apache, MySQL and PHP) in one step. Update all packages before do this.

Remove PHP 7.0 and install PHP 5.6

PHP 5.6 for Ubuntu 16 can be installed from PPA (Personal Package Archives) for PHP (5.6, 7.0):

Add PPA to the repositories

• root@ubuntu16:~# add-apt-repository ppa:ondrej/php
  root@ubuntu16:~# apt-get update

Remove the currently installed PHP 7.0 packages, check the list of the packages first and complete the list below

• root@ubuntu16:~# dpkg --get-selections | grep -i php
  root@ubuntu16:~# apt-get purge libapache2-mod-php7.0 php-common php-mysql php-pear php-xml php7.0-cli php7.0-common php7.0-dev php7.0-json php7.0-mysql php7.0-opcache php7.0-readline php7.0-xml pkg-php-tools

Install PHP 5.6 with PEAR and PEAR packages

• apt-get --no-install-recommends install php5.6 php5.6-mysql php5.6-dev php5.6-xml php5.6-mbstring php-pear
  pear install Log Mail Mail_Mime Mail_mimeDecode Net_SMTP Net_Socket Services_JSON

Check again installed PHP 7.0 packages an remove them:

• root@ubuntu16:~# dpkg --get-selections | grep -i php
  root@ubuntu16:~# apt-get purge ....

Install PECL packages also directly from the PPA

• apt-get --no-install-recommends install php-propro php-raphf php-pecl-http

Configure php.ini

• root@ubuntu16:~#  cd /etc/php/5.6/apache2
  root@ubuntu16:~#  cp php.ini php.ini-ORIG
  root@ubuntu16:~#  vi php.ini
  root@ubuntu16:~#  diff php.ini-ORIG php.ini

  < max_execution_time = 30
  ---
  > max_execution_time = 120
  466c466
  < display_errors = Off
  ---
  > display_errors = On
  572c572
  < ;error_log = php_errors.log
  ---
  > error_log = /var/log/php_errors.log

  ---
  > session.gc_maxlifetime = 36000

  The session timeout (timeout for automatic logout) is set also in php.ini. See Setting Session Timeout.

  Install a browscap.ini file. Download php_browscap.ini from http://browscap.org/stream?q=PHP_BrowsCapINI, change the name to browscap.ini, and save it in the /etc with permission 644.

  Change also /etc/php/5.6/cli/php.ini, apply only display_errors and include_path from the changes above.

Perl modules

• Add some perl modules:

  root@ubuntu16:~# apt-get install libconfig-general-perl

httpd Configuration

• Apache2 (httpd) configuration is very easy, only the virtual host definitions must be added and appropriate apache modules should be loaded.

Adding Apache Modules

• root@ubuntu16:~# a2enmod rewrite dav auth_digest authz_groupfile

Restart Apache

• systemctl restart apache2.service

Install Image Magick

• To allow to create thumbnail files ghostscript and ImageMagick must be installed. The versions in the Ubuntu distribution are quite old. Newer versions must be installed:

    # Ghostscript and ImageMagick are part of the Ubuntu distribution (currently versions 9.18 and 6.8.9-9)
   
    apt-get install ghostscript imagemagick

Install TexLive 2015

To allow to create LaTeX submital/transmittal cover letters TexLive >= 2011 must be installed.

• root@ubuntu16:~# apt-get install texlive latexmk texlive-latex-extra

Install htmldoc

• root@ubuntu16:~# apt-get install htmldoc

Create drawmgt User and Group

• root@ubuntu16:~# adduser --uid=1003 drawmgt
  root@ubuntu16:~# usermod -a -G www-data drawmgt
  root@ubuntu16:~# usermod -a -G drawmgt www-data

Minimal puppet client setup

• vagrant@xenial-rails:~$ sudo su -
  root@:~# apt install puppet-common
  root@ubuntu16:~# cd /etc/puppet
  root@ubuntu16:~# rm -rf [efmt]*
  root@ubuntu16:~# vi puppet.conf
  [agent]
    server      = puppet
    report      = true

Notes

MySQL Passwords

• Use ~/-my.cnf instead of command line passwords for all DrawMGT users using mysqlcopy.pl or backupClient.pl to avoid problems caused by the warning of current MySQL version: mysql: [Warning] Using a password on the command line interface can be insecure.
  Use mysqlcopy.pl without -p option and do not define password in the configuration file for backupClient.pl.

  [mysqldump]
  user=root
  password=sqladmin
  [mysql]
  user=root
  password=sqladmin
