NGINX, FastCGI a HTTPS (Nette, CakePHP, Python...)

2013-01-22T11:43:00.000+01:00

Spravne nastavene server variables pro FastCGI pres NGINX

Po prechodu na PHP-FPM nam zacala zlobit aplikace, ultimate redirect.

Zjistill jsem, ze aplikace nam posila 301 a adresu nasi aplikace obohacenout o port 80.

Po 3 hodinach bylo jasne, ze se aplikace snazi aplikace presmerovat na non-HTTPS verzi. Ale proc? HTTPS zapnute nebylo?

NGINX od verze 1.1.11 defaultne nepredeva informaci o tom, zda je pripojeni zabezpecene ci nikoliv, toto zprostredkovava tento radek:

fastcgi_param HTTPS $https;

pokud $https neni nastavene; preda se prazdna hodnote ''

pokud pouzivate SSL, neni to problem, hodnota bude 'on'

nette s touto operaci pracuje, a pokud HTTPS nechce tak se snazi nas presmerovat na non-HTTPS, ale chudinka je furt presvedcena o tom, ze mi SSL pouzivame, tak to zase posle.

Reseni pro non-ssl (pokud musite mit HTTPS v server variables)

nginx configuration:

fastcgi_param HTTPS                 off;

Reseni pro ssl-enabled:

fastcgi_param HTTPS                 on;
fastcgi_param SSL_PROTOCOL          $ssl_protocol;
fastcgi_param SSL_CIPHER            $ssl_cipher;
fastcgi_param SSL_SESSION_ID        $ssl_session_id;
fastcgi_param SSL_CLIENT_VERIFY     $ssl_client_verify;

Credits: http://claylo.com/post/7617674014/ssl-php-fpm-and-nginx

Univerzalnejsi a lepsi reseni, pokud vam bude stacit, ze tam pro non-SSL HTTPS nebude vubec:

fastcgi_param HTTPS           $https if_not_empty;

O.K. nasel jsem mraky postu, kde se tvrdi, ze linux verze Google Drive je na spadnuti a ve skutecnosti je konektor v ubuntu jiz od verze 11.11.

Vse co potrebujete je aplikace grive

nainstalujte si ji: sudo apt-get install grive

pokud neni nalezena tak proste pridejte PPA:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install grive

Pri prvnim startu si vlezte do adresare, kde chcete soubory synchronizovat, protoze presne tam kde budete se stahnou.

cd /home/jan/googleDrive

grive -a

Aktualizace (28.10.2012)

Pro ubuntu jiz existuje balicek s appletem. Je dostupny pro:

insync-beta-cinnamon - Insync for Desktop Linux - (beta9) - cinnamon
insync-beta-gnome - Insync for Desktop Linux - (beta9) - gnome
insync-beta-gnome-cinnamon-common - Insync for Desktop Linux - (beta9) - gnome-cinnamon-common
insync-beta-kde - Insync for Desktop Linux - (beta9) - kde

Takze doporucuji, do budoucna by se z toho udajne mela stat komercni aplikace, ale do te doby to snad pujde i jinak.

Netbeans IDE a pozice kurzoru na menu

2012-10-02T13:19:00.001+02:00

Pouzivam Netbeans na Linuxu uz roky, a co jsem si nainstaloval MINT misto obvykleho Ubuntu (miluju Gnome 3 menu) jako pomstu za Unity. Ted tam mam Cinnamon, tedy Gnome 3, ale s normalnim panelem, konfigurovatelny, 3D app switch a tak.

No k veci.

Problem:

Pri kliknuti na menu v NB se menu sice zobrazi, ale poloha kurzoru je posunuta oproti fakticke poloze indikovane kliknutim na polozku menu. Zjednodusene: pokud drzim, po kliknuti na polozku menu, leve tlacitko misy stiskle a posunu ji dolu, je indikovana, jako vybrana polozka, polozka mimo faktickou pozici kurzoru, v mem pripade o 2cm vyse.
Problem se vyskytuje vyhradne v menu, coz je sice videt, ale dokud nad tim nezacnete premyslet jako nad problemem s menu... JAVU jsem vyloucil na zaklade toho, ze ostatni aplikace fungovali tak jak meli. Ale trosku pozde...

Reseni:

Musime zmenit startup options pro netbeans v configuracnim souboru. Pokud mate Netbeans nainstalovane pod rootem tak muzete zmenit bud:

/usr/local/netbeans-X.Y/etc/netbeans.conf

,nebo vytvorte

~/.netbeans/X.Y/etc/netbeans.conf a zkopirujte do nej obsah vyse uvedeno souboru

Najdete radek zacinajici: netbeans_default_options

Muj vypada takto, dulezite je: -J-Dapple.laf.useScreenMenuBar=false
Puvodne to bylo povolene, ale presne toto zpusobilo ten problem.

Funkcni verze s tematem Metal, odstrante --laf Metal pokud si to neprejete.

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=false -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=false -J-Dsun.zip.disableMemoryMapping=true --laf Metal"

Tak a je to...

PHP 5.3.16 na Ubuntu, redis

2012-08-29T12:42:00.000+02:00

Dnes jsem nainstaloval redis, zkousel jsem jak balicek z distra: 2.2, tak vlastni kompilaci 2.4, bohuzel to porad nejelo, php proste vytuhlo, resp. cekalo. Pripojeni probehlo OK, bohuzel query bezely nelidsky pomalu.

Po delsim hledani jsem zjistil, ze PHP 5.3.10 z distra nefunguje ani s jendou verzi jak by melo.
Pro instalaci PHP 5.3.16, ktera s Redis funguje nadherne:

Do /etc/apt/sources.list pridejte:
deb http://packages.dotdeb.org stable all
deb-src packages.dotdeb.org stable all

Import GPG klice aby nebyl APT ukecanej:
wget -q -O- dotdeb.org/dotdeb.gpg | apt-key add -
Update APT:
sudo apt-get update
(volitelne) upgrade co lze:
sudo apt-get upgrade
Install nove PHP:
sudo apt-get install php5

Test:
$ php -v

Logitech Unified Receiver, MX Performance mouse, (x)buntu 12.04

2012-08-18T14:01:00.002+02:00

Tak jsem si poridil krasnou mys, kterou bohuzel nemohu pouzivat na linuxu, wokna ok, ale nekupuju si takovouhle mys kvuli herni konzoli, ze?! Obecne je to problem s tim Unified Receiver-em v tehle verzi. Ja jsem to pouzil na MX Performace Mouse.

Takze jsem zjistil, ze nejsem sam, kdo ma tento problem, zatim existuji dva workaroundy co jsem nasel.

1) pridejte do /etc/rc.local

modprobe -r hid_logitech_dj
modprobe hid_logitech_dj

2) otevrete /etc/modprobe.
d/blacklist.conf
odkomentujte "blacklist usbmouse" (zmen na "#blacklist usbmouse") nebo odstrante radku celou a restartujte system

Instatni reseni:

sudo modprobe -r hid_logitech_dj && sudo modprobe hid_logitech_dj

Netbeans 7 pekne na Linuxu (Ubuntu)

2012-08-15T09:26:00.001+02:00

Pokud mate hnusne Netbeansy tak to obycejne byvaji fonty ve Vasem JRE, bud si nainstalujte jine JRE, jako Oracle Sun:

sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin

nebo si jen aktivujte jiny styl pro netbeans. V adresari netbeans, /usr/local/netbeansX
najdete etc/netbeans.conf

do promenne netbeans_default_options pridejte nakonec pred posledni uvozovky:

--laf Nimbus -J-Dswing.aatext=true -J-Dawt.useSystemAAFontSettings=lcd

Muj radek pak vypada takto:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true --laf Nimbus -J-Dswing.aatext=true -J-Dawt.useSystemAAFontSettings=lcd"

GIT web frontend

Casto potrebujete nejaky pristup ke svemu GIT repu, idealne i k projektu, obcas je vyhodne pouzivat nejaky unifikovany, uz jenom kvuli odkazum na ruzne patche a diffy.

Par reseni jsem vyhledal, nesnazim se je hodnotit!

Zakladni:

gitweb, nativni (vyvijeny gitem) v PERL
cgit C
git-php PHP
ViewGit PHP

Komplikovanejsi (vice sluzeb):

gitorious RUBY
InDefero PHP, klon GoogleCode with git, Mercurial, SVN
GitLab

Nejvice je obecne doporucovany GitLab, tak prilozim screenshot a odkaz.

GREP search and replace

2012-07-29T22:19:00.003+02:00

Nasel jsem krasnej post:

Use this command:

egrep -lRZ "\.jpg|\.png|\.gif" . \
    | xargs -0 -l sed -i -e 's/\.jpg\|\.gif\|\.png/.bmp/g'

egrep: find matching lines using extended regular expressions
-l: only list matching filenames
-R: search recursively through all given directories
-Z: use \0 as record separator
"\.jpg|\.png|\.gif": match one of the strings ".jpg", ".gif" or ".png"
.: start the search in the current directory
xargs: execute a command with the stdin as argument
-0: use \0 as record separator. This is important to match the -Z of egrep and to avoid being fooled by spaces and newlines in input filenames.
-l: use one line per command as parameter
sed: the stream editor
-i: replace the input file with the output without making a backup
-e: use the following argument as expression
's/\.jpg\|\.gif\|\.png/.bmp/g': replace all occurrences of the strings ".jpg", ".gif" or ".png" with ".bmp"

Batch update URL aliases in Joomla 2.5

2012-07-17T10:00:00.000+02:00

Jak nastavit spravne URL aliasy pro existujici zaznamy v databazi.

Zjistil jsem, ze Joomla neumi odstranit diakritiku z nazvu tak aby friendly URL bylo spravne a č nebylo smazano. Nenasel jsem zadny nastroj, ktery by to dokazal opravit nad existujicimi zaznamy, tak jsem si napsal malinkej PHP script.

Prepiste si ho tak aby jste mohli parametry zadavat treba v konzoli, tohle byla jednorazovka.

mb_internal_encoding('UTF-8');

$conn = mysql_connect('localhost','xxxxx','xxxxxxx');
mysql_select_db('xxxxxx');
mysql_query('set names utf8');

$result = mysql_query('select * from j25_content order by id desc');
while ( $record = mysql_fetch_assoc($result) ) {
    $found = mysql_query('select count(*) matched from j25_content where `alias`="'.addslashes(seoUrl($record['title'])).'" and id<>'.$record['id']);
    $foundM = mysql_fetch_assoc($found);
    $alias = seoUrl($record['title']);
    if ($foundM['matched']>1)
    {
        $duplicates++;
        $alias.="-".(intval($found['matched'])+1);
        echo ('[!!] ' . $record['alias']. 'would be duplicit, changed to: '.$alias."\n");
    }
    if ($record['alias']!=$alias) {
        echo ('[++] ' . $record['alias']. ' changed to '.$alias.' from title "'.$record['title'].'"'."\n");
        mysql_query('update j25_content set alias="'.$alias.'" where id='.$record['id']);
        $modified++;
    } else {
        $correct++;
    }

}
$result = mysql_query('select * from j25_menu order by id');
while ( $record = mysql_fetch_assoc($result) ) {
    $found = mysql_query('select count(*) matched from j25_menu where `link`="'.addslashes(seoUrl($record['title'])).'" and id<>'.$record['id']);
    $foundM = mysql_fetch_assoc($found);
    $alias = seoUrl($record['title']);
    if ($foundM['matched']>1)
    {
        $duplicates++;
        $alias.="-".(intval($foundM['matched'])+1);
        echo ('[!!] ' . $record['alias']. 'would be duplicit, changed to: '.$alias."\n");
    }
    if ($record['link']!=$alias) {
        echo ('[++] ' . $record['link']. ' changed to '.$alias.' from title "'.$record['title'].'"'."\n");
        mysql_query('update j25_menu set alias="'.$alias.'", path="'.$alias.'" where id='.$record['id']);
        $modified++;
    } else {
        $correct++;
    }

}

echo mysql_num_rows($result)." analyzed, $correct was ok, $modified has been modified, $duplicates was duplicate...\n";

/**
* Return URL-Friendly string slug
* @param string $string
* @return string
*/

function seoUrl($string) {
        //Unwanted: {UPPERCASE} ; / ? : @ & = + $ , . ! ~ * ' ( )
        $string = mb_strtolower($string);
    $string = iconv('UTF-8','ASCII//TRANSLIT',$string);
        //Strip any unwanted characters
        $string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
        //Clean multiple dashes or whitespaces
        $string = preg_replace("/[\s-]+/", " ", $string);
        //Convert whitespaces and underscore to dash
        $string = preg_replace("/[\s_]/", "-", $string);
        return $string;
}

Update/Install Java Oracle JDK on Ubuntu 10-12.04

2012-07-16T12:20:00.001+02:00

Pokud potrebujete pro nektere program JDK od javy misto OpenJDK, ktere ma dost problemu s vykonem a zobrazenim tak existuje PPA repositar, kde to lze jednoduse updatnout do aktualni verze.

Jak na to:

K pridani PPAv Ubuntu (12.04, 11.10, 11.04 and 10.04):

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Pokud vse probehlo bez chyby tak kontrola:

java -version

Meli by jste videt neco podobneho:

java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) Server VM (build 23.0-b21, mixed mode)

The package installs all the Java binaries, so you can also try "javac -version" which should return "javac 1.7.0_04" and so on (the "_04" part of the version can be different because I'm constantly updating the PPA with the latest Oracle Java 7 version).

If for some reason, the Java version in use is not 1.7.0, you can try to run the following command:

sudo update-java-alternatives -s java-7-oracle

Tak dneska opet budu instalovat Eclipse Ganymede a PDT 2.0 nightly build. Posledne se mi nepodarilo nainstalovat 'code assist' pro vestavene PHP funkce. Asi jsem to jenom nenasel.

Navod k zakladni instalaci je mozne najit na http://wiki.eclipse.org/PDT/Installation

Pro vetsinu instalaci pluginu pouzivam starsi 3.3 update system, ktery se zapne pres preference, general. Je to rychlejsi.

Pak uz pluginy, ktere nesmeji chybet.
