Problem

My programmer has this error while uploading file in wordpress

Solution

Find php.ini file location

php -i | grep 'php.ini'

Change this value inside in php.ini

upload_max_filesize = 12M
post_max_size = 13M
memory_limit = 15M

Or add this code to first line of .htaccess file (is located in WordPress installation directory)

php_value upload_max_filesize 12M
php_value post_max_size 13M
php_value memory_limit 15M

Note:

Change the file size with your case study

ERROR 1130 (HY000): Host '123.32.23.12' is not allowed to connect to this MySQL server

My Problem

I want to connect to mysql server using my personal computer but I have this error.

ERROR 1130 (HY000): Host '123.32.23.12' is not allowed to connect to this MySQL server

My Solution

Make sure your IP have access to database server

SELECT host FROM mysql.user WHERE User = 'root';

If you only see results with localhost and 127.0.0.1, you cannot connect from an external source. If you see other IP addresses, but not the one you're connecting from - that's also an indication.

You will need to add the IP address of each system that you want to grant access to, and then grant privileges:

CREATE USER 'root'@'ip_address' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'ip_address';

If you see %, well then, there's another problem altogether as that is "any remote source". If however you do want any/all systems to connect via root, use the % wildcard to grant access:

CREATE USER 'root'@'%' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';

Finally, reload the permissions, and you should be able to have remote access:

FLUSH PRIVILEGES;

The uploaded file exceeds the upload_max_filesize directive in pnp.ini (wordpress)

Indra Wahyu — Wed, 01 May 2024 07:06:34 +0000

My Problem

I want to upload files in WordPress with large file size, but have error "The uploaded file exceeds the upload_max_filesize directive in pnp.ini"

My Solution

Go to wordpress directory. for e.g:

cd /var/www/html/wordpress

Open file .htaccess

nano .htaccess

Add the following line at the bottom of the file:

php_value upload_max_filesize 256M

Then Save the changes.

That’s it! Increasing the upload_max_filesize value should automatically fix the error.

if not work, try to restart your web server (e.g. apache/nginx)

Composer is operating significantly slower than normal because you do not have the PHP curl extension enabled.

Indra Wahyu — Fri, 19 Jan 2024 05:56:24 +0000

I want to run composer update but I have this problem

And I solved it with just install PHP curl extension.

sudo apt-get install php-curl

Port 5000 is in use by another program. Either identify and stop that program, or start the server with a different port.

Indra Wahyu — Mon, 02 Oct 2023 16:48:41 +0000

Problems

I accidentally pressed ctrl + z on the terminal so that the previously running flask stopped abnormally and the port was still used

I can't run flask again because the port is being used

Solution

Check what ports are being used

sudo ss -tulpn

Kill pid from the port being used

kill -9 4837

Try to run flask again

python3 app.py

Function to Create New Directory and Jump Into it Immediately

Indra Wahyu — Sun, 23 Apr 2023 11:58:25 +0000

I want to create command to create new directory and jump into it immediately and I found this solution. Just add md () { mkdir "$1" && cd "$1" ; } function to .bashrc. Oke this is my intruction.

Go to home directory

cd ~

Open and edit .bashrc file with vim or nano

nano .bashrc

Add function to end of command. Exit with ctrl+x y and enter

md () { mkdir "$1" && cd "$1" ; }

Reopen your terminal or restart it

exec bash -l

Now you can create new directory and jump into it immediately with

md directory_name
