How could the missing MySQL extension required by WordPress be installed?

[Susmita/Rajib]

Dear illustrious leaders and the senior members, Debian-user ML,

I liked the following two papers of Prof. Shri C K Raju:
ajol-file-journals_601_articles_221195_submission_proof_221195-7072-545591-1-10-20220325.pdf
https://www.ajol.info/index.php/ajct/article/download/221195/210502
ajol-file-journals_601_articles_222634_submission_proof_222634-7072-544552-1-10-20220309.pdf
https://www.ajol.info/index.php/ajct/article/download/222634/210050

and I tried to read Prof. Shri C K Raju's blog pages, say the one at
http://ckraju.net/blog/?p=189

I received a Firefox-esr notice:
"Your PHP installation appears to be missing the MySQL extension which
is required by WordPress."

Searching the internet, I reached the Stack Overflow page with the
partial title:
Your PHP installation appears to be missing the MySQL extension which
is required by WordPress
at:
https://stackoverflow.com/questions/17694568/php-your-php-installation-appears-to-be-missing-the-mysql-extension-which-is-r#22779915

I followed both the first solution and the approved solution. I
searched in synaptic:
mysql-server
php5-mysql
apache

The nearest that are available in Debian Bullseye :
default-mysql-server
default-mysql-server-core
php-mysql
php7.4-mysql
apache2
php-db
along with their dependencies.

I installed them all. Then I tried to follow the instructions:
# sudo /etc/init.d/mysql status
sudo: /etc/init.d/mysql: command not found

# sudo /etc/init.d/mysql start
sudo: /etc/init.d/mysql: command not found

# /etc/init.d/apache2 restart
Restarting apache2 (via systemctl): apache2.service.

The blog pages still fail to load.

Please feel free to advise.

Best wishes,
Rajib
Etc.

That is the old Sysvinit method.
Use systemd tools instead

systemctl status mysql

Can you use the php info function to get information about the php
stuff that is being loaded?

Can you now try to create your own php script that makes use of that to
test it?

Dear Mr. M, thank you for replying to my email. Unfortunately, I am
incapable of designing a such php script. Beyond my cognitive level. I
am just a user with very rudimentary programming skills.

In the meanwhile, I also contacted Prof. Shri C K Raju. He informed me that:
"...
The blog is not working since the php has to be updated, and that
would make other php elements malfunction."
"Some of the blog entries are restored at
https://ganita.net/to-decolonise-math-stand-up-to-its-false-history-and-bad-philosophy/
..."

I suggested:
"...This could be addressed differently. If the blogs are in plain html,
they could be downloaded with a website downloader. In linux users
generally employ webhttrack website copier. Have the articles stored
in a permanent medium such as an optical DVD-RW or a HDD. Then
restructure the entire website differently so that the blogs could be
kept intact across software upgrades with a static html file under the
index.html hierarchy. ..."

However, Mr. M, please feel free to suggest your advice with appropriate inputs.

Best wishes,
Rajib

Hmm, you seem to be chasing fairies. PHP is a server-side technology,
so I don't think the error message is telling you that you have
something wrong. It's telling you that http://ckraju.net has something
wrong. It's not very helpful but if you want to look at the blog, you
need to contact him and ask him to fix his website.

[debia...@howorth.org.uk]

No, no, no. He shouldn't be installing PHP on his machine! It's a
security nightmare he's opening himself up to and it won't solve his
problem anyway!

Thank you Mr. debian-user for replying to my thread.

Fortunately, I have heard from Prof. Raju himself and the gist of that
conversation is contained in the post:
https://lists.debian.org/debian-user/2023/11/msg00405.html

It would be nice of you to go through this above pos and suggest an
improvement in my post to Prof. Raju.

I apologise that you was writing and editing my email when you posted,
and I didn't update the archive page to know that you have posted.

Now, I will have to uninstall the components that I installed trying
to solve the issue that couldn't be solved in the way attempted.

Please feel free to post your suggestions.

There isn't unfortunately a roll-back feature for debian a feature
known to me with which I could take a snapshot of the system before
installing new packages, so that if anything went wrong, I could
uninstall the packages installed to get back to the previous snapshot.

Best wishes,
Rajib

Apologise for the typos and incorrect sentence constructions in my
earlier post. But I am sure that Mr. would be able to bypass the
errors to extract the information intended for him.

php-common
apache2
apache2-bin
apache2-data
mariadb-client-10.5

and then an apt autoremove.

Then perhaps an apt-purge apache2 .. and so on.
Then go back and remove any outlying packages that have not already been
removed until you have no more left.

For the future - for any reader of this list, not just Rajib:

If you don't know quite what you're installing and a single package installs
lots of other packages, stop and consider before you install. Meta-packages
like desktops pull in lots of dependencies, but so, as you've seen does
PHP

If you're really not sure: read lots then ask. If you say

"I want to do X. I think that means I need to install Y and configure Z.
>From reading ABC pages, I _think_ that means that I need to do the
following but I'm not sure because page C says to do this and I don't
understand. I'm running Debian 12.2 updated this week. "

- it becomes a lot easier to understand what you want.

If you explain _exactly_ what error messages you get and how you get them
that helps significantly. If you've done a web search and found a possible
answer or that other people have had a similar problem, add that in.

"I'm getting error message DEF from running this command. From the net,
it looks as if other people have been having similar problems on older
versions of Debian but not recently - am I reading this correctly"

It shows that you have made an attempt to problem solve for yourself and
people will be more willing to help and explain their suggestions.
If the advice you get solves a problem - post that back to the list
in the thread and change the message subject slightly to make it
clear that this is an answer. For example:

[SOLVED] Package foo fails to install in Debian 12.2. [Was: Cannot install
foo]

It is always possible that no-one else has ever seen anything similar. The
advice you get from people here may always be a best guess as to a solution.
The more clearly you can give information, the easier the problem solving
becomes.

If you have to ask lots of questions around the same subject, consider
stopping and writing a summary post to write down what you've learned
and solutions you have tried so far.

SUMMARY - Package bar still failing to install after several tries

"I have been given solution A in a post in this thread on November 1st.
I did this but then got error message B - see post on November 3rd
so I did C on November 4th. The problem I have now is that the
error message is DE"

Hope this helps,

Andy

Ok. Thank you Mr. Cater, for your guidance.

I sincerely apologise, Mr. Cater.
I am not posting an excuse, but sometimes, the excitement of the
prospect of a new perspective and more wisdom becomes too overpowering
to restrain myself from undue risk-taking. A millennium of lost
opportunities, trampled hopes and prospects, the lack of a beautiful
and fulfilling community life and a prosperous society enhances the
excitement exponentially. In this regard we share our common pain with
the Israelis, suffering from multiple-centuries of genocide even many
times more than the 2nd World War Holocaust. Our foodgrains were
repeatedly diverted, causing many man-made famines for more than a
century, killing and displacing my ancestors and made us more
susceptible to diabetes and heart diseases. But as the Israelis also
endorse, the only people that didn't persecute them were us.

My conscience cries for the sufferings of a grand continuous
civilisation and her peoples, Mr. Cater.

Prof. C K Raju's articles entice with the prospect of identifying the
real perpetrators of such inhuman atrocities with more evidence. So
the excitement couldn't be contained.

Yes, I have followed the general sensible guidelines. But in
excitement I couldn't restrain myself from experimenting. I didn't
consider the problem to be so irritating. So I didn't consider that I
would have to ask for support later. I sincerely apologise, Mr. Cater.

By good coincidence, I follow this sensible recording of experiences.
But thank you for reminding and consolidating the idea behind the
actions in a clearer language.

There is one problem with this approach, as stated earlier. For the
Mailing list, any change of subject from my Gmail webmail email-server
makes such an email detached from the main thread and treats it as a
different subject. Had Mailman also had an email editor for posting
messages, that would have been a better option.

However, I understand the difficulties and the legalities associated
with this added functionality and acknowledge the associated problems,
since FSF has to bear with the Deep State more, bringing an added
peril to itself. We already know the fate of Assange, Snowden and
myriads of unknown others.

In countries where the Law owes its existence to Xtian Morality
legitimising flat earth, land grab, usurpation, genocides, may the
real Hive Mind of the Holographic Universe, the Brahm, save us from
the faux construct.

The people who choose to empower us, despite facing all perils, have
our fullest admiration and wellwishes.

Between the two options therefore, I usually choose to keep all the
posts consolidated within a single thread for the future users. I hope
that with your greater experience, expertise and wisdom, you would be
able to guide me in this regard, w.r.t. gmail and Mailman.

All your notes shall be remembered, Mr. Cater. Thank you and best wishes.

For all the debian-users who might fall into the same ditch into which
I had fallen, to alert them ...

I thank Mr. Cater for his advice at
https://lists.debian.org/debian-user/2023/11/msg00443.html. I raed his
advice and understood that while uninstalling I should follow a path
chronologically reverse to the one I had followed while installing all
those packages on the 10th Nov 2023.

So what I did was that I noted down his advice on a plain text editor,
then opted for "uninstall completely ..." the following packages:

php-common
apache2
apache2-bin
apache2-data
mariadb-client-10.5

Following my practice of safety, I kept a note of the packages I had
installed, as recorded in my first post of this thread, at:
https://lists.debian.org/debian-user/2023/11/msg00384.html
as follows:
[quote]

The nearest that are available in Debian Bullseye :
default-mysql-server
default-mysql-server-core
php-mysql
php7.4-mysql
apache2
php-db
along with their dependencies.

I installed them all. ...
[/quote]

Then I went to my list of synaptic installation history and from the
block categories described earlier in:
https://lists.debian.org/debian-user/2023/11/msg00411.html,
individually selected the still unselected packages. All of them,
listed on the History list of 10th November 2023.

With a little anxiety, I proceeded for a complete uninstallation.

The Uninstallation completed without an error message (synaptic
reported in the "Changes Applied" window: "Successfully applied all
changes...") as follows:

So a SUMMARY becomes due:
To note down the bulk packages while installing, follow a path
chronologically reverse to the one followed during installing, then
from the "History of installed, upgraded and removed packages" also
select the associated packages installed along with the bulk packages
and remove them together at one shot.

So thank you all, Mr. Cater, Mr. debian-user and Mr. M, for your
gentle confidence-building pushes. In between, I also reported a troll
lurking.

Best wishes,
Rajib
Etc.

After being shocked to learn in this year 2023 that gmail web
interface does not do threading, and that changing the subject line
will break such an email out from what gmail considers the
"conversation" and into a new "conversation", I wondered how many
people reading this list use gmail and might thus be confused by
this practice.

Of course, I cannot tell how many passive readers there are of this
list, so all I could check was the posters.

For the last year back from today inclusive:

686 unique emails
363 unique domains
1: 213 addresses from gmail.com (31.0%)
2: 16 addresses from debian.org (2.3%)
3: 10 addresses from protonmail.com (1.5%)
4: 9 addresses from yahoo.com (1.3%)
5: 8 addresses from gmx.net (1.2%)
6: 7 addresses from gmx.com (1.0%)
7: 6 addresses from mailbox.org (0.9%)
8: 6 addresses from outlook.com (0.9%)
9: 5 addresses from posteo.de (0.7%)
10: 5 addresses from web.de (0.7%)

Mind boggling.

(Neither would I be able to tell how many of those gmail.com users
read using the gmail web interface or their own MUA through IMAP
etc.)

I stopped using gmail with my own MUA because of duplicates that can't be
easily deleted when you fetch mails. gmail considers a duplicate as
already fetched and don't show it. So I had to log on the webmail to
delete them. Perhaps not a problem if you use IMAP and let the mails on
gmail.

Well 'yours truly' is one passive reader that uses Gmail on this list. Of
course I use mutt (which does proper threadeing) with it and rarely touch
the web interface. I've had no issues with threading from Gmail, when using
IMAP with mutt.
