Network Upgrade for Ubuntu Servers

  1. Ensure you're up to date with latest release:

    sudo apt-get update
    sudo apt-get upgrade
  2. Install update-manager-core if it is not already installed:

    sudo apt-get install update-manager-core
  3. edit /etc/update-manager/release-upgrades and set Prompt=lts

Note: The minumum contents of /etc/update-manager/release-upgrades should be

[DEFAULT] Prompt=lts
  1. Launch the upgrade tool:

    sudo do-release-upgrade
  2. Follow the on-screen instructions.
  3. At the end of the upgrade process you will be required to restart the server in order to boot into the new kernel. If you do not have access to the console of the system you are upgrading, you may need to edit /boot/grub/menu.lst and change the default boot kernel to the newly installed 10.04 kernel. If this step is not performed your server may attempt to boot into the 8.04 LTS kernel and will hang.

Instal·lant una màquina blava - 4) PHP 5.4

I finalment, instal·lem PHP. Al tractar-se d'una màquina de desenvolupament, instal·larem PHP 5.4 Release Candidate 1 i així podrem provar les noves opcions de PHP 5.4 com els traits per a evitar algunes limitacions de les herències úniques pròpies de PHP. Aquestes novetats s'integraran properament a l'IDE NetBeans.

Recuperarem el codi font de PHP:

svn checkout https://svn.php.net/repository/php/php-src/branches/PHP_5_4 php-src-5.4

Preparem llibreries i programes que necessitem per a crear el PHP 5.4 com a mòdul per a l'Apache instal·lat a l'apartat 3 d'aquesta sèrie.

apt-get install aspell curl libaspell-dev libbz2-dev libc-client-dev libcurl4-openssl-dev libfreetype6 libfreetype6-dev libjpeg62 libjpeg62-dev libmcrypt4 libmcrypt-dev libmhash2 libmhash-dev libming-dev libmysqlclient15-dev libncurses-dev libpng3 libpng12-dev libpspell-dev libreadline-dev libsasl2-dev libsnmp-dev libt1-5 libt1-dev libtidy-dev libxml2 libxml2-dev libxml2-utils libxpm4 libxpm-dev libxslt1-dev make build-essential autoconf bison

Configurem el PHP

cd php-src-5.4


./configure --with-apxs2=/usr/bin/apxs2 --disable-short-tags --with-openssl --with-zlib --enable-bcmath --with-bz2=/bin/bzip2 --enable-calendar --with-curl --with-curlwrappers --enable-exif --enable-ftp --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-xpm-dir=/usr/lib --with-t1lib --enable-gd-native-ttf --enable-gd-jis-conv --with-gettext --with-imap --with-imap-ssl --with-ldap --with-ldap-sasl --enable-mbstring --with-mcrypt --with-mhash --with-ibm_db2=/opt/ibm/db2/V9.7 --with-pspell --with-readline --with-snmp --enable-soap --enable-sockets --with-tidy --enable-wddx --with-xmlrpc --with-xsl --enable-zip --with-pear --with-kerberos

I procedim a compilar, en una màquina amb 4GB de RAM i 2 processadors a 2,6GHz hem trigat 16 minuts.

make && make install

Instal·lem el php.ini preparat per a desenvolupament

cp php.ini-development /usr/local/lib/php.ini

Instal·lem el mòdul ibm_db2

pecl install ibm_db2

Indicant /opt/ibm/db2/V9.7 com a carpeta on tenim instal·lat el DB2, o allà on pertoqui.

afegim la secció ibm_db2 al php.ini


Arrenquem l'apache

/etc/init.d/apache2 restart

I certifiquem que funciona fent

echo "" > /var/www/index.php
rm /var/www/index.html

I obrint un navegador que apunti al servidor obtindrem

Si volem tenir també opcions de MySQL:

./configure --with-apxs2=/usr/bin/apxs2 --disable-short-tags --with-openssl --with-zlib --enable-bcmath --with-bz2=/bin/bzip2 --enable-calendar --with-curl --with-curlwrappers --enable-exif --enable-ftp --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-xpm-dir=/usr/lib --with-t1lib --enable-gd-native-ttf --enable-gd-jis-conv --with-gettext --with-imap --with-imap-ssl --with-ldap --with-ldap-sasl --enable-mbstring --with-mcrypt --with-mhash --with-ibm_db2=/opt/ibm/db2/V9.7 --with-pspell --with-readline --with-snmp --enable-soap --enable-sockets --with-tidy --enable-wddx --with-xmlrpc --with-xsl --enable-zip --with-pear --with-kerberos --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd

Instal·lant una màquina blava - 3) IHS : IBM HTTP Server

Per tal de servir planes web i interpretar PHP al vol, instal·larem l'IHS, l'IBM HTTP Server, que és un Apache millorat i assegurat. Pel que es veu, no s'integra dins del WAS i cal instal·lar-ho separat. És a dir que si no tenim intenció de servir aplicacions Java, ens podem saltar el pas 1.

El descarregarem del web d'IBM: IBM HTTP Server i procedim a instal·lar-ho com indica el document Hosting PHP applications on the IBM HTTP Server (gràcies Francisco) :

tar -xvf ihs.7000.linux.ia32.tar /root
cd IHS

Copiem responsefile.txt a opcions.txt editem aquest darrer i acceptem la llicència i modifiquem altres valors per omissió i esborrem la secció de windows:

-OPT silentInstallLicenseAcceptance="true"
-OPT disableOSPrereqChecking="true"
-OPT installLocation="/opt/IBM/HTTPServer"
-OPT createAdminAuth="true"
-OPT adminAuthUser="ihsadmin"
-OPT adminAuthPassword="xxxx"
-OPT adminAuthPasswordConfirm="xxxx"
-OPT runSetupAdmin="true"
-OPT setupAdminUser="ihsadmin"
-OPT setupAdminGroup="www-data"
-OPT washostname="blue.corretge.ct"

I executem la instal·lació en mode silenci, doncs no tenim instal·lades les X al servidor:

java -cp `pwd`/setup.jar -Xms48m -Xmx384m run -options "opcions.txt" -silent

I a nosaltres ens ha cascat. Bé, el fet d'estar en una distribució no suportada per IBM deu haver generate els problemes, així que instal·larem un Apache, serà una màquina blava al 50%. A fi de comptes l'IHS s'arrenca amb la instrucció apachectl.

sudo apt-get install apache2 apache2-threaded-dev apache2-mpm-prefork apache2-utils

I obtenim fàcilment el It works! de la felicitat.

Més endavant ja enllaçarem WASCE amb Apache HTTP Server via mod_jk.

Instal·lant una màquina blava - 2) DB2 Express Community Edition

Procedirem a la instal·lació de la base de dades d'IBM, la DB2 en la seva versió lliure de cost, la DB2 Express-C. Hi ha moltes versions, amb unes possibilitats molt interessants, però per a un entorn de desenvolupament, amb la CE en fem suficient.

Amb els repositoris partner activat, tal i com s'indica a l'apartat 1 de la sèries de posts Instal·lant una màquina blava, procedirem a instal·lar DB2 desde la paqueteria d'Ubuntu.

sudo apt-get install db2exc

Un cop instal·lat canviarem les contrasenyes dels usuaris creats:

sudo passwd db2inst1
sudo passwd db2fenc1
sudo passwd dasusr1

Ens loginegem com l'usuari gestor de les instàncies DB2, i certifiquem que s'ha instal·lat correctament:

sudo su db2inst1

DB21085I Instance "db2inst1" uses "64" bits and DB2 code release "SQL09074"
with level identifier "08050107".
Informational tokens are "DB2 v9.7.0.4", "s110330", "IP23243", and Fix Pack
Product is installed at "/opt/ibm/db2/V9.7".

Creem una nova base de dades, per exemple CORRETGE ;-)

sudo su db2inst1
db2 create database CORRETGE

Cal tenir en compte que quan diem una base de dades, és un sistema de bases de dades, és a dir un objecte que conté esquemes on cada esquema conté taules i cada taula registres.

Ah, i si no voleu tenir problemes, millor definir els noms de tots els objectes en caixa alta, així evitarem haver d'emprar les cometes a l'hora de qualificar-los, i evitar perdre el temps fins que te n'adones que el problema era aquest. Avisats esteu.

Literatura sobre IBM DB2 Express-C.

Per a poder gestionar còmodament la base de dades, en una màquina client amb les X activades instal·larem l'IBM Data Studio, una perspectiva d'eclipse per a la gestió de qualsevol de les DB2 existents al mercat. Descarreguem el full client des del DownloadDirector d'IBM.

que executarem amb la instrucció

Instal·lant una màquina blava - 1) WebSphere Application Server Community Edition

En aquesta sèrie de posts explicaré com instal·lar una màquina blava, una particular manera de celebrar el centenari d'IBM, amb l'IBM HTTP Server, IBM DB2 i PHP 5.4 en un Ubuntu Server 10.04 LTS de 64 bits.

D'ençà la versió 6.0 de l'IHS (IBM Http Server) aquest producte només s'instal·la amb el WAS (WebSphere
Application Server). Per a fer-ho des del servei de paqueteria d'ubuntu, editarem l'arxiu /etc/apt/sources.list i descomentarem els reposioris partner :

deb http://archive.canonical.com/ubuntu lucid partner

I actualitzem:
sudo apt-get update

Procedim a instal·lar el paqet WAS CE Community Edition, d'utilització lliure de pagament i més lleguer.

sudo apt-get install wasce-server

I bé, ja el tenim instal·lat, comprovem l'status del servidor
sudo /etc/init.d/wasce-server status
* Websphere CE is running

Però no el veiem operatiu!
Executant el que fa l'start de wasce-server des de root, veiem que es triga prop de quatre minuts en arrencar, en una màquina amb dos processadors i 4GB de RAM, així que és questió d'esperar-se fins accedir al WebSphere Application Server Community Edition pel port 8090 i accedir a la cònsola administrativa.

Usuari: system
Contrasenya: manager

No cal dir que s'ha de canviar anant al menú Security/Users and Groups.

The IBM i From a PHP Programmer's Perspective

Al número d'octubre de la revista php|architect hi ha un interessant article sobre PHP i IBM i (AS/400)

IBM and Zend have pushed hard to prove that PHP on the IBM i is a viable solution, and it is. While they tend to gear most of their marketing toward mainframe developers to switch over to PHP, coming to the IBM i from a PHPers experience is a whole different matter. We know the language, just not this well-aged platform. IBM has done their best to make developers welcome but the environment is still different. I'll go through some of the common annoyances of having to work on the i, as well as tips to make life easier. This is not an introduction to programming on the i, just tips to make your life easier. –by Chris Tankersley

Zend Reveals DBi, A New Version of MySQL for IBM i

by Alex Woodie from http://www.itjungle.com/tfh/tfh092611-story02.html

IBM i shops that were hesitant to deploy pre-packaged PHP apps on the platform because of the end of MySQL support from Oracle can go forward with their plans now thanks to the public unveiling of Zend DBi, a new IBM i-specific version of MySQL that Zend Technologies will develop, maintain, and support. Zend DBi is slated to ship with the upcoming December release of the Zend PHP software stack for the IBM i server, the company said last week.

Ever since Oracle announced plans to drop MySQL support for i5/OS V5R4 and IBM i 6.1 last December, IBM and Zend have been working to figure out a way to keep the open source database alive on the platform. MySQL is a critical piece of the PHP puzzle, since the majority of pre-packaged PHP applications (such as SugarCRM, Joomla, and Drupal) were designed to use MySQL. Developers writing new PHP apps aren't affected as much, as they can hit the DB2/400 database directly.

The solution to the problem became evident last week when Zend officials shared details of the forthcoming Zend Server 5.5 for IBM i release, which is expected to become generally available in December. The new PHP stack will contain Zend DBi, which Zend's IBM alliance director Michael Scarpato calls a "drop in replacement" for the old release of MySQL for IBM i.

Scarpato on Friday outlined for IT Jungle the current state of MySQL on IBM i support and the plans for making Zend DBi the second officially supported database for the platform. "The status quo at the moment is fine. We ship MySQL as part of Zend Server for 5.1. It's still available from the Oracle website," he says.

"The question in the minds of folks in the i community who rely on MySQL is, 'Who's going to take care of it as it goes forward?'," Scarpato asked rhetorically. "So as problems emerge in the code, or as security fixes need to be applied, or if there's some killer new feature that comes out for other platforms that is very relevant for the i platform as well, how do we get that over? Who's going to take care of that? It's an open source project. So anybody could do it. But who's really going to take responsibility to care and feed it, and then make commercial support available for the community who would like it? So that's going to be Zend."

The initial release of Zend DBi will be, for all intents and purposes, functionally identical to the last supported MySQL for IBM i release to come out of Oracle, even if the actual code isn't quite the same. Zend hasn't finished porting it over, so it's impossible to say how much the code bases will look alike. But the plan going forward is for Zend DBi to diverge from the last supported version of MySQL from Oracle, Scarpato says.

Any changes that Zend makes will be posted back to the MySQL open source project, as per the terms of the GNU GPL license that both MySQL and Zend DBi are distributed under. However, there are currently no plans to make Zend DBi an open source project in its own right, Scarpato says. No beta releases of Zend DBi are planned.

Zend is putting in a lot of work to port Oracle's MySQL source code to IBM i, says Allison Butterill, the Power Systems application development offering manager at IBM. "Oracle provides source code on its website, and anybody can download and create binaries, but it's nowhere close to a trivial task," she says. "Zend is taking that on and will use that code for MySQL as the base for what they're going to provide with Zend DBi."

IBM will continue to develop the IBMDB2i storage engine, which enables PHP applications that use MySQL to actually store data in DB2/400. A new release of the storage engine that works with Zend DBi will be available with Zend Server 5.5 for IBM i in December.

Besides the new database, Zend Server 5.5 for IBM i will also mark the general availability of the new open source XML Toolkit that Zend and IBM have co-developed. The new toolkit, which we first covered in April, was designed to do a better and more transparent job of connecting PHP applications with existing IBM i programs and services. The old toolkit, which was developed by AURA Equipments, will continue to work with Zend Server 5.5, even though it's not distributed as part of the new PHP stack, Zend's senior director of product management Kent Mitchell says.

The new IBM i release of Zend Server 5.5 will bring several other enhancements that have been available for Windows and Linux users for several months. Zend says these include new deployment and IT automation features that will help ease the handoff of PHP applications from development to operations teams, as well as new application delivery functions and automated scaling of enterprise PHP applications.

The new stuff--Zend DBi, the XML Toolkit, and Zend Server 5.5 functions--will be discussed in great detail at the forthcoming ZendCon 2011 conference, which is scheduled for October 17 through 20 in Santa Clara, California. Zend has devoted an entire track to PHP on IBM i topics. PHP on IBM i pros who will be presenting at ZendCon include Mike Pavlak, Alan Seiden, Tony Cairns, and Tim Rowe.

PHP 5.2 discontinued

Good news for the PHP community, Johannes Schlüter says:

All PHP users should note that the PHP 5.2 series is NOT supported
anymore. All users are strongly encouraged to upgrade to PHP 5.3.8.

If you are currently in 5.2 and plans to go to 5.3, read the Migrating guide... previously :)

Why is a good choice upgrade to 5.3.x?

  • Support for namespaces

  • Late static binding

  • Lambda Functions and Closures

  • Syntax additions: NOWDOC, ternary short cut "?:" and jump label (limited goto), __callStatic()

  • Under the hood performance improvements

  • Optional garbage collection for cyclic references

  • Optional mysqlnd PHP native replacement for libmysql

  • Improved Windows support including VC9 and experimental X64 binaries as well as portability to other supported platforms

  • More consistent float rounding

  • Deprecation notices are now handled via E_DEPRECATED (part of E_ALL) instead of the E_STRICT error level

  • Several enhancements to enable more flexiblity in php.ini (and ini parsing in general)

  • New bundled extensions: ext/phar, ext/intl, ext/fileinfo, ext/sqlite3, ext/enchant

  • Over 140 bug fixes and improvements to PHP, in particular to: ext/openssl, ext/spl and ext/date

  • Added "max_file_uploads" INI directive, which can be set to limit the number of file uploads per-request to 20 by default, to prevent possible DOS via temporary file exhaustion.

  • Added missing sanity checks around exif processing.

  • Fixed a safe_mode bypass in tempnam().

  • Fixed a open_basedir bypass in posix_mkfifo().

  • Improved LCG entropy. (Rasmus, Samy Kamkar)

  • Added a 3rd parameter to get_html_translation_table. It now takes a charset hint, like htmlentities et al.

  • Methods with the same name as the last element of a namespaced class name will no longer be treated as constructor. This change doesn't affect non-namespaced classes.

  • Added ability to connect to HTTPS sites through proxy with basic authentication using stream_context/http/header/Proxy-Authorization.

  • Added options to debug backtrace functions.

  • Fixed bug #54939 (File path injection vulnerability in RFC1867 File upload filename). Reported by Krzysztof Kotowicz. (CVE-2011-2202)

  • And more Key and Security Enhancements and Fixes.

    baobab l'analitzador d'ocupació de disc gràfic

    Si mai hem d'analitzar l'ocupació d'un disc, per a mostrar l'ocupació de les carpetes i subcarpetes, emprarem la comanda

    sudo du --max-depth=1 -x /

    Però si estem en un entorn gràfic, podem emprar la comanda baobab que fa el mateix que du, però amb capacitat de drill-down i molt còmoda d'emprar, tenim l'aplicació baobab, que pertany al paquet gnome-utils.
