Wordpress gyorsítás tapasztalatok - cache, bővítmények .htaccess, PHP

• Mindennek az alapja egy jó "SSD"-s szerver (tárhely), ami gyors válaszidővel rendelkezik
• Illetve egy gyors téma, pl. GeneratePress
• Cache bővítmények: WP Super Cache, Hummingbird
• Képoptimalizálók: Webp, Hummingbird
• Képek gyorsítása CDN, pl. Jetpack
• DDoS védelem, biztonság CDN, pl. Cloudflare
• Ha a szerver támogatja az LSPHP-t, a .htaccess fájlba beírni:

AddHandler application/x-httpd-lsphp74 .php .php5

És a teszt :)

Monit.php malware eltávolítása

Monit.php reklámvírus (malware)

Hogyan tudod megállapítani, hogy fertőzött vagy-e? 

A [honlap-URL]-t cseréld ki a te honlapod címére (pl. https://sajathonlapom.hu)

[honlap-URL]/wp-admin/options-general.php?page=monit

Automatikus eltávolítás: cPanel cron 

A tárhely cpanel felületén találod meg a "Időzített feladatok(cron)" lehetőséget:

Állítsd be hogy percenként egyszer lefusson:

A YOUR_EMAIL_ADDRESS helyére ha beírod az email címedet, akkor értesítést kapsz ha megtalálta (és letörölte) a monit.php-t a rendszer.

find . -type f -name "monit.php" -exec echo {} \; -exec stat {} \; -exec rm -f {} \; | mailx -E -s "monit.php threat deleted" YOUR_EMAIL_ADDRESS

Másik módszer eltávolításra: Anti-Malware from GOTMLS.NET

https://gotmls.net/

Ajánlom a telepítését! Ha tetszett, akkor 29$ adományért cserébe már rendszeres, automatikus frissítéseket is beállíthatod, de az ingyenes változat is remekül használható.

Kézi eltávolítás:

1. Töröljük le a fájlkezelővel plugins/monit.php

Vagy ssh parancssorban: find /var/www/html/ -name monit.php -exec rm -rf {} \;

2. A MySQL adatbázisban található javascript fájlok, melyek a nem kívánt reklámokat megjelenítik:

<script type="text/javascript" src="//ofgogoatan.com/apu.php?zoneid=3280383" async data-cfasync="false"></script>

<script src="https://propu.sh/pfe/current/tag.min.js?z=3280389" data-cfasync="false" async></script>

<script type="text/javascript" src="//inpagepush.com/400/3336702" data-cfasync="false" async="async"></script>

2 JBEBP("<script*.php?zone*</script>") in wp_options:ad_code":167655.1

SQL parancs amit a phpMyadmin felületre be lehet másolni, aztán a megtalált táblákat törölni:

SELECT * FROM `wp_options` WHERE `option_name` IN ( ‘default_mont_options’, ‘ad_code’ , ‘hide_admin’, ‘hide_logged_in’ , ‘display_ad’, ‘search_engines’ , ‘auto_update’, ‘ip_admin’ , ‘cookies_admin’, ‘logged_admin’, ‘log_install’)

Add an A, AAAA, or CNAME record for your root domain so that DOMAIN_NEVE.hu will resolve.

Add an MX record for your root domain so that mail can reach @DOMAIN_NEVE.hu addresses.

Some of your DNS only records are exposing IPs that are proxied through Cloudflare. Make sure to proxy all A, AAAA, and CNAME records pointing to proxied records to avoid exposing your origin IP.

Docker telepítés - Fix Docker mess Ubuntu 18.04

sudo apt purge docker.io docker-compose

sudo apt install docker.io docker-compose

docker-compose is already the newest version (1.17.1-2).

docker.io is already the newest version (19.03.6-0ubuntu1~18.04.1).

@whysthatso Just ran into this issue, could you please describe the full solution step by step? Do I need to uninstall docker-compose and stuff and then reinstall docker or what?

as far as i remember:

• uninstall everything docker-related
• check if there is /etc/systemd/system/docker.service, delete it
• install docker-compose

or it could be:

• uninstall everything docker-related

but yeah, sorry, i realized i should have contextualized my comment a bit better

• install docker-compose
• check if there is /etc/systemd/system/docker.service, delete it

try both, can't really mess anything up here

kwmartin commented

Needed all of: apt-get remove and re-install using curl as Kirill-Babkin suggests (and restart socker to be safe) add user to docker group using usermod sudo usermod -aG docker $USER logout and login undefine DOCKER_HOST (as suggested by rkazak at https://forums.docker.com/t/docker-commands-require-sudo/12987/2) which I had earlier set using > export DOCKER_HOST=127.0.0.1:2375 as suggested by jamethy and shin This was on an RPi 3B. After all of this, docker is now working. Is there any chance this could be cleaned up so others don't have to go through this painful experience, as it is experiences like this docker is designed to fix? Just a suggestion. https://github.com/docker/compose/issues/4181 sudo service docker restart

PDF fájl átalakítása Wiki formátumra

sudo apt install pandoc

sudo apt-get install poppler-utils

PDF --> HTML

sudo mkdir kimenet

sudo pdftohtml -s -p -fmt png -nodrm "file.pdf" "file/file.html"

You can type pdftohtml -h to gain a better understanding of available parameters.

I've explained the parameters used here for the sake of understanding the command:

• -s contains all of the output within one HTML document (excluding the outline.
• -p attempts to replaces pdf internal linking with html links.
• -fmt controls the output format of images, with png and jpg being valid options.
• -nodrm igores download rights management restrictions on the PDF.
• -i ignores images. I didn't use this, but it felt prudent to mention as in some cases it may massively speed your output format.

Alternatív módszer: Poppler pdftotext

pdftotext -htmlmeta "file.pdf" "file.html"

 Replace "file" with the name of the file you want to parse and with the name of the HTML file you want to write your text output to. 
 The `-htmlmeta` option creates an HTML version of the text in your PDF. (This is much less fancy than the previous command and only puts the text in `pre` tags). You should see an HTML file in your directory which you can open to check the results of. Depending on the formatting of your source PDF file, you may find that Poppler is variable in it's effectiveness. You can try running `pdftotext -h` for information on other command options that may improve or worsen your results. 

Pandoc: HTML --> MediaWiki

 pandoc file.html -f html -t mediawiki -s -o file.txt

• -f bemeneti formátum
• -t kimeneti formátum
• -s Standalone adds a header and footer to the document, rather than producing a document fragment.
• -o The name of the output file.

Pandoc user guide.

It is possible you may run into an error with Pandoc, presumably caused by your file being too large. I ran into this error and some fixes can be found here.

Opció: rossz kódolás kitakarítása

Depending on your PDF encoding, you may find strange Unicode charecters in your HTML output. This step is intended to clean up this output to the best possible degree of accuracy. ftfy, stands for fixes text for you, and it's a Python library with a command-line interface. We'll be using the command line to clean our files. This step is preformed before using Pandoc.

ftfy telepítése:

git clone https://github.com/LuminosoInsight/python-ftfy.git
cd python-ftfy
sudo python setup.py install

Or, if you system has pip, pip install ftfy. Note that if you want to use a version of 5.0 (most recent available at time of writing) or later, you need Python 3. I used Python 2.x with ftfy 4.1.1 for this answer. Using the same directory, type the following command:

 ftfy -o file_clean.html --preserve-entities file.html

Optionally, you may include the --guess option to have ftfy guess your encoding, or --encoding if you know your encoding. This may produce better results.

Syntax errors in translated files - Letter to poeditor.com

I've used poeditor with Google Translate to translate open source software - LearnPress and Give-WP plugins.

I've paid 8$ yet the output is full of syntax errors - special characters like & and $ are messed up, some important extra lines omitted starting with # (see e.g. Learnpress WP plugin PO file, lines: "#, php-format").

Examples from Give-WP translation - full source below:

1. Unwanted character conversion - and worse, bad output due to extra space:
msgid "Next »"
msgstr "Következő & raquo;"

2. Extra spaces added that breaks variables:
msgid "Edit Donor: %1$s %2$s"
msgstr "Adományozó szerkesztése:% 1 $ s% 2 $ s"

3. Wrong character encoding:
msgid "Before - %s&#x200e;10"
msgstr "Előtt -% s &# x200e; 10"

etc...

Original:
https://www.pastefs.com/pid/211223

Translated but with syntax errors
https://www.pastefs.com/pid/211222

The Transifex translation portal also does not accept the file you generate as an input file due to the syntax errors.

Can you fix these errors?
