how to get database back while xampp is not working - database

I have created a database in MySQL using XAMPP But In Some How My XAMPP Server is Not Working Now I am trying to Get My data Back

It's in
xampp\mysql\data
folder. Or you can export the database in PHPmyadmin.

If you use Linux, you can install mysql-client and mysql-server:
sudo apt-get install mysql-client
sudo apt-get install mysql-server
and then access to phpMyAdmin with navigate to where you extract mysql. Then run this command:
php -S localhost:80
If you use windows, you can use an alternative software instead. I think Laragon is a good alternative software.

Accessing existing windows postgresql database in WSL

I already have postgresql installed (psql (PostgreSQL) 13.4) and the local server set-up on my windows machine (along with pgAdmin4), and already have some databases in it.
I've recently installed WSL and planning on using it instead of windows+bash going forward. Hence I'm installing postgresql 13 for WSL. I follow https://pgdash.io/blog/postgres-13-getting-started.html for the installation:
# add the repository
> sudo tee /etc/apt/sources.list.d/pgdg.list <<END
> deb http://apt.postgresql.org/pub/repos/apt/ focal-pgdg main
> END
# get the signing key and import it
> wget https://www.postgresql.org/media/keys/ACCC4CF8.asc sudo apt-key add
> ACCC4CF8.asc
# fetch the metadata from the new repo
> sudo apt-get update
> sudo apt-get install -y postgresql-13
It installed postgres with psql --version = psql (PostgreSQL) 13.4 (Ubuntu 13.4-1.pgdg20.04+1)
Then I start the service with
> sudo service postgresql start
> sudo -u postgres psql
My questions are:
When I check the list of databases I have using \l, I can't see my existing postgres database that I have in my windows machine, why? and how do I connect/import it to the wsl?
How do I make the WSL database/server appears in my existing pgAdmin4 GUI? I have already a server for my windows machine (localhost, port 5432). How can I add database from the WSL server, since it has the same settings? For example, I tried creating new database via WSL psql command line CREATE DATABASE ubuntu;, and the new database appears in the WSL postgres list in terminal, but the pgAdmin GUI only shows database from my windows server. How do I sync both databases in windows and WSL and show them both in pgAdmin?
database list in windows (from pgAdmin4)
database list in WSL
Thanks for the help

How to connect puckel/docker-airflow to local windows SQL Server?

So, I'm trying to connect to my local instance of SQL Server on windows from airflow dag.
The major error is that pyodbc or pymmssql libraries are not installed even after explicitly mentioning them in the docker file. I've followed the instructions from Microsoft ODBC Driver for SQL Server under Debian 9 and Medium as the image is built on it.
All the tasks in dag run fine except for the one I am trying to connect to the SQL Server with the error:
[2020-04-03 22:23:42,303] {{taskinstance.py:1128}} ERROR - No module
named 'pyodbc'
If I try pip install from the airflow container it is not installing in the /usr/lib/python3.7/site-packages and not able to import in the dag.
I have also included requirements.txt in the volume but had no luck.
Did anyone had a successful connection in this scenario?
I was able to solve this issue by building the airflow image form the Dockerfile. while building you need to add few dependencies.
sqlalchemy:
&& pip3 uninstall SQLAlchemy \
&& pip3 install SQLAlchemy==1.3.15 \
pyodbc:
&& apt-get install python3-dev -y\
&& apt-get install unixodbc-dev -y\
&& pip3 install pyodbc \
Another long way would be to change the USER as root and build the image and ap-get install from the container and change change the USER back to airflow but this is more efficient if you know what you are installing.

postgreSQL error initdb: command not found

i was installing postgresql on ubuntu using linuxbrew:
brew install postgresql
it seems to work fine but after that because i was installing PostgreSQL for the first time i tried creating a database:
initdb /usr/local/var/postgres -E utf8
but it returned as:
initdb: command not found
i tried running the command with sudo but that doesn't helped
run locate initdb it should give you the list to chose. smth like:
MacBook-Air:~ vao$ locate initdb
/usr/local/Cellar/postgresql/9.5.3/bin/initdb
/usr/local/Cellar/postgresql/9.5.3/share/doc/postgresql/html/app-initdb.html
/usr/local/Cellar/postgresql/9.5.3/share/man/man1/initdb.1
/usr/local/Cellar/postgresql/9.6.1/bin/initdb
/usr/local/Cellar/postgresql/9.6.1/share/doc/postgresql/html/app-initdb.html
/usr/local/Cellar/postgresql/9.6.1/share/man/man1/initdb.1
/usr/local/bin/initdb
/usr/local/share/man/man1/initdb.1
So in my case I want to run
/usr/local/Cellar/postgresql/9.6.1/bin/initdb
If you don't have mlocate installed, either install it or use
sudo find / -name initdb
There's a good answer to a similar question on SuperUser.
In short:
Postgres groups databases into "clusters", each of which is a named collection of databases sharing a configuration and data location, and running on a single server instance with its own TCP port.
If you only want a single instance of Postgres, the installation includes a cluster named "main", so you don't need to run initdb to create one.
If you do need multiple clusters, then the Postgres packages for Debian and Ubuntu provide a different command pg_createcluster to be used instead of initdb, with the latter not included in PATH so as to discourage end users from using it directly.
And if you're just trying to create a database, not a database cluster, use the createdb command instead.
I had the same problem and found the answer here.
Ubuntu path is
/usr/lib/postgresql/9.6/bin/initdb
Edit: Sorry, Ahmed asked about linuxbrew, I'm talking about Ubuntu.
I Hope this answer helps somebody.
I had a similar issue caused by the brew install postgresql not properly linking postgres. The solve for me was to run:
brew link --overwrite postgresql
you can add the PATH to run from any location
sudo nano ~/.profile
inside nano go to the end and add the following
# set PATH so it includes user's private bin if it exists
if [ -d "/usr/lib/postgresql/14/bin/" ] ; then
PATH="/usr/lib/postgresql/14/bin/:$PATH"
fi
and configure the alternative
sudo update-alternatives --install /usr/bin/initdb initdb /usr/lib/postgresql/14/bin/initdb 1

How do I install/update to Postgres 9.4?

I just installeed Postgres, but it seems to have installed 9.3 and I'd like to start with 9.4
I simply did apt-get install postgresql from a new Ubuntu 14.04.1 machine.
http://www.postgresql.org/download/linux/ubuntu/
says you can do:
apt-get install postgresql-9.4
but when I try that I get:
E: Couldn't find any package by regex 'postgresql-9.4
Okay, so I try the section below where you add the PostgreSQL Apt Repository but that can't find anything either.
Is 9.4 not in the package managers yet? Am I doing something horribly wrong?
You can add it from the instructions in the page
http://www.postgresql.org/download/linux/ubuntu/
Create the file /etc/apt/sources.list.d/pgdg.list, and add a line for the repository
deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main
Import the repository signing key, and update the package lists
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update && sudo apt-get install postgresql-9.4
postgresql-9.4 is not available in 14.04 "Trusty". It was added in 14.10 "Utopic". It may be back ported in the future.
The directions on the PostgreSQL Ubuntu Download page are missing a command. Their wiki guide has the correct procedure. You must run apt-get update before trying to install. This will cause the system to read changes to the sources.
If you're trying to install on Ubuntu 14.04 "Trusty", you can follow these steps:
To check your version:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty
1) Create new apt repo file for postgres
$ echo "deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main" > /etc/apt/sources.list.d/pgdg.list
2) Import repository signing key and update packages list
$ sudo wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
$ sudo apt-get update
3) Install Postgres
$ sudo apt-get install postgresql-9.4

Below are steps to install PostgreSQL 9.4 on Ubuntu 14.04.
Reference taken from this Article:
First, check the version of Ubuntu:
lsb_release -sc
You need to add the latest PostgreSQL repository for the latest version, otherwise It will install PostgreSQL 9.3. This is for trusty version.
sudo add-apt-repository "deb https://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main"
Update and Install PostgreSQL 9.4:
sudo apt-get update
sudo apt-get install postgresql-9.4
Default postgres super user and postgres database is created. You need to set a password for the postgres super user.
ubuntu#:~$ sudo passwd postgres
Enter new UNIX password:****
Retype new UNIX password:****
passwd: password updated successfully
If service is not started, you can start the PostgreSQL service.
sudo service postgresql start
Connect PostgreSQL server using postgres user:
ubuntu#:~$ su postgres
Password:****
Create a sample database:
createdb database_name
Connect to that database:
psql -d database_name
Follow these steps to install postgresql. Open the terminal (Ctrl + Alt + t) and then write down the following command line
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.6
If postgresql installed successfully then it will return this after writing this command
psql --version
psql (PostgreSQL) 9.6.3
PostgreSQL is an open source object-relational database system. It is one of leading database server used for production servers. PostgreSQL allows us to execute stored procedures in various programming languages, like PHP, C/C++, Python, Java, Perl, Ruby and its own PL/pgSQL, which is similar to Oracle’s PL/SQL.
Postgres database is used the persistent store of data
Install Postgres
yum install postgres
(Note : remember the password for the postgres user – you need it later)
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install postgresql-9.6
Setting up Postgres
Launch pgAdmin.
Connect to the local server. Use localhost for the server name, postgres for the username and the password you used when you installed Postgres.
You need to be root to perform this command.Note: If you did not set password during installation (sudo apt-get install postgresql), then you can set it as follows:

sudo -u postgres psql postgres
On the postgres client prompt, use the following command to set the password.
alter user postgres with password 'postgres';
Connect to PostgreSQL
After installing PostgreSQL database server, by default,, it creates a user ‘postgres’ with role ‘postgres’. It also creates a system account with same name ‘postgres’. So to connect to postgres server, log in to your system as user postgres and connect database.
$ sudo su - postgres
$ psql
Now you are logged in to PostgreSQL database server. To check login info use following command from database command prompt.
postgres-# \conninfo
To disconnect from PostgreSQL database command prompt just type below command and press enter. It will return you back to Ubuntu command prompt.
postgres-# \q

CakePHP 3.0 installation: intl extension missing from system

Using the CakePHP docs, I am trying to install 3.0-beta2 using composer but I got this error:
cakephp/cakephp 3.0.x-dev requires ext-intl * -> the requested PHP extension intl is missing from your system
However, I know for sure that intl is installed (it shows on phpinfo). I'm using PHP 5.4.33/Apache 2.4.10.1
I faced the same problem today. You need to enable the intl PHP extension in your PHP configuration (.ini).
Solution Xampp (Windows)
Open /xampp/php/php.ini
Change ;extension=php_intl.dll to extension=php_intl.dll (remove the semicolon)
Copy all the /xampp/php/ic*.dll files to /xampp/apache/bin
Restart apache in the Xampp control panel
Solution Linux (thanks to Annamalai Somasundaram)
Install the php5-intl extension sudo apt-get install php5-intl
1.1. Alternatively use sudo yum install php5-intl if you are on CentOS or Fedora.
Restart apache sudo service apache2 restart
Solution Mac/OSX (homebrew) (thanks to deizel)
Install the php5-intl extension brew install php56-intl
If you get No available formula for php56-intl follow these instructions.
Restart apache sudo apachectl restart
Eventually you can run composer install to check if it's working. It will give an error if it's not.
I faced the same issue in ubuntu 12.04
Installed: sudo apt-get install php5-intl
Restarted the Apache: sudo service apache2 restart
OS X Homebrew (May 2015):
The intl extension has been removed from the main php5x formulas, so you no longer compile with the --enable-intl flag.
If you can't find the new package:
$ brew install php56-intl
Error: No available formula for php56-intl
Follow these instructions: https://github.com/Homebrew/homebrew-php/issues/1701
$ brew install php56-intl
==> Installing php56-intl from homebrew/homebrew-php
When using MAMP
1 Go to terminal
vim ~/.bash_profile
i
export PATH=/Applications/MAMP/bin/php/php5.6.2/bin:$PATH
Change php5.6.2 to the php version you use with MAMP
Hit ESC,
Type :wq,
hit Enter
source ~/.bash_profile
which php
2 Install Mac Ports
https://www.macports.org/install.php
sudo port install php5-intl OR sudo port install php53-intl
cp /opt/local/lib/php/extensions/no-debug-non-zts-20090626/intl.so /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/
{take a good look at the folder names that u use the right ones}
3 Add extension
Now, add the extension to your php.ini file:
extension=intl.so
Usefull Link:
https://gist.github.com/irazasyed/5987693
The error message clearly states what the problem is. You need the intl extension installed.
Step 1: install PHP intl you comfortable version
$sudo apt-get install php-intl
step 2:
For XAMPP Server intl extension is already installed, you need to enable this extension to uncomment below the line in your php.ini file. Php.ini file is located at c:\xampp\php\php.ini or where you have installed XAMPP.
Before uncomment:
;extension=php_intl.dll ;extension=php_mbstring.dll
After uncommenting:
extension=php_intl.dll extension=php_mbstring.dll
Short answer: activate intl extension in php_cli.ini. Thanks to #ndm for his input.
If you are using latest version Ubuntu 16.04 or later just do
sudo apt-get install php-intl
Then restart your apache
sudo service apache2 restart
In my case I was not actually trying to run cakephp locally, I was just trying to get it to auto update locally using composer (because I am playing with writing plugins that you install with composer). Since I don't actually even run it locally I could simply ignore requirements by adding the --ignore-platform-reqs flag.
php composer.phar update --ignore-platform-reqs
In my case, my running php version is 7.1.x on mac OSX .
I installed intl command using brew install php71-intl.
Placing extension=intl.so inside php.ini was no effect at all. Finally i looked for extension installed directory and there i saw intl.so and placed that path (extension=/usr/local/Cellar/php71-intl/7.1.11_20/intl.so) to my php.ini file and it solved my problem.
In my case (xampp PHP 8.0)
Find ;extension=intl in /xampp/php/php.ini
Remove ; and Restart Apache
MAKE this
In XAMPP, intl extension is included but you have to uncomment extension=php_intl.dll in php.ini and restart the server through the XAMPP Control Panel.
In WAMP, the intl extension is “activated” by default but not working. To make it work you have to go to php folder (by default) C:\wamp\bin\php\php{version}, copy all the files that looks like icu*.dll and paste them into the apache bin directory C:\wamp\bin\apache\apache{version}\bin. Then restart all services and it should be OK.
if you use XAMPP do this
1. turn off XAMPP
2. Modifed the php.ini is located in c/:xampp/php/php.ini
3. intl extension is included but you have to uncomment extension=php_intl.dll in php.ini and restart the server through the XAMPP Control Panel.
For Ubuntu terminal:
Please follow the steps:
Step-1:
cd ~
Step -2: Run the following commands
sudo apt-get install php5-intl
Step -3: You then need to restart Apache
sudo service apache2 restart
For Windows(XAMPP) :
Find the Php.ini file:
/xampp/php/php.ini
Update the php.ini file with remove (;) semi colon like mentioned below:
;extension=php_intl.dll to extension=php_intl.dll
and save the php.ini file.
After that you need to
Restart the xampp using xampp control.
Intl Means :Internationalization extension which enables programmers to perform UCA-conformant collation and number,currency,date,time formatting in PHP scripts.
To enable PHP Intl with PECL can be used.
pecl install intl
On a plain RHEL/CentOS/Fedora, PHP Intl can be install using yum
yum install php-intl
On Ubuntu, PHP Intl can be install using apt-get
apt-get install php5-intl
Restart Apache service for the changes to take effect.
That's it
For those who get Package not found error try sudo apt-get install php7-intl then run composer install in your project directory.
I had the same problem in windows
The error was that I had installed several versions of PHP and the Environment Variables were routing to wrong Path of php see image example
I'm using Mac OS High Sierra and none of these worked for me. But after searching a lot I found one that worked!
This may seem trivial, but in fact about 2 months ago some clever guys made changes in brew repository, so doing just: brew install php71-intl will show you error with message that such recipe doesn’t exists.
Fortunately, there is. There is temporary fix in another brew repo, so all you have to do is:
brew tap kyslik/homebrew-php
brew install kyslik/php/php71-intl
SOURCE: http://blastar.biz/2018/04/14/how-to-enable-php-intl-extension-for-php-7-1-using-xampp-on-macos-high-sierra/
I use Linux Ubuntu 20, you can try this:
Check php installed modules:
php -m | grep intl
If there are no result(s) from this command, you should just go ahead and install the module:
sudo apt-get install php7.4-intl
you will need to change *php7.4 to your desired php version.
you should restart apache when you're done:
sudo service apache2 restart
