Laravel 5.4 on PHP 7.0: PDO Exception - Could not

问题:

I have a Laravel 5.4 project on my Ubuntu 14.04 (VPS with Plesk 12.5.30). After creating the database and setted up the .env file with required information I ran php artisan migrate and exceptions were thrown:

[Illuminate\Database\QueryException]
could not find driver (SQL: select * from information_schema.tables where table_schema = pmaramaldb and table_name = migrations)

[PDOException]
could not find driver

My .env file has:

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=pmaramaldb

DB_USERNAME=user

DB_PASSWORD=password

I've followed most of the guides to solve this error and there wasn't any positive results:

Enabling Extension Solution:

PDO is enabled

The php.ini file is being generated automatically, I guess this is made by Plesk. At the start of the file it says:

; ATTENTION!
;
; DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
; SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.

So I've tried it anyway. After that I've restarted Apache and then tried again... Didn't work.

Installing php7.0-mysql Solution:

I've also tried to install MySQL in case is not:

user@server:/var/www/vhosts$ sudo apt-get install php7.0-mysql

php7.0-mysql is already the newest version.

0 actualizados, 0 se instalarán, 0 para eliminar y 67 no actualizados.

** SQL Lite Install Solution:**

I've also tried as question link says: sudo apt-get install php5-sqlite and the result was:

user@server:/var/www/vhosts/system/maramal.io/etc$ sudo apt-get install php5-sqlite

php5-sqlite is already the newest version.

Composer Dump-autoload Solution:

It didn't work either. I've tried composer dump-autoload and it didn't work.

After ran the command php -i:

PDO

PDO support => enabled

PDO drivers =>

...

PHP Version => 5.6.30-1+deb.sury.org~trusty+1

Well, I am not sure if this has anything to do with the error, but the version shown by running php -v is:

user@server: ~/path$ php -v

PHP 5.6.30-1+deb.sury.org~trusty+1 (cli)

There's a conflict between the PHP that is used by Apache and the PHP that is linked to the command line. (It happens more often that it should to be honest).

What is typically done is:

which php

This tells you which php will be expecuted when running in the command line. e.g. /usr/bin/php

mv /usr/bin/php /usr/bin/php.old

Then link or copy the correct PHP version to an executable path:

ln -s /path/to/php/bin/php /usr/bin/php

or the following should also work.

cp /path/to/php/bin/php /usr/bin/php

Also suggested if you want to be able to manually install mods:

ln -s /path/to/php/bin/phpize /usr/bin/phpize
ln -s /path/to/php/bin/php-config /usr/bin/php-config

This way your CLI will match your webserver.

As an alternative solution be sure you have installed php7-mysql

try to run command below

sudo apt install php7.0-mysql

回答3:

Same problem, ubuntu 17.10, Laravel 5.5.

$ sudo apt install php7.1-pdo php7.1-mysql

A nice quick fix, hope this helps

回答4:

I had the same scenario you have. I did resolve mine the following:

1) on your terminal, type

php --ini

this will output your current php.ini configuration file path.

2) edit php.ini using vim or your preferred editor.

vim /etc/php.ini

note that /etc/php.ini is your path file for your php.ini. it may be different on your machine.

3) find ;extension=php_pdo_mysql.dll and uncomment it by removing semicolon (;)

4) save your php.ini change/s

**5) restart the web server to apply the changes

sudo systemctl restart apache2

**6) Now run your command.

php artisan migrate

hope this helps for you.

回答5:

Your database driver is missing. To solve the probelem

First install the driver

For ubuntu: For mysql database.

sudo apt-get install php5.6-mysql/php7.2-mysql

You also can search for other database systems.

You also can search for the driver:

sudo apt-cache search drivername

回答6:

clear artisan cache

php artisan cache:clear

and

php artisan migrate:refresh

that's it

回答7:

You can try these following command

php artisan cache:clear
php artisan config:clear  

Then restart your apache server. After then reconfigure your .env file

Actually, I'm pretty sure that you are not aware of your PHP - versions and used the wrong paths:

For your vendor PHP version ( 5.6 by sury.org ), you would use PHP - commands as "/usr/bin/php", but when you use different PHP - versions, as for example the ones from Plesk, then you have different paths:

/opt/plesk/php/5.2/bin/php -v
/opt/plesk/php/5.3/bin/php -v
/opt/plesk/php/5.4/bin/php -v
/opt/plesk/php/5.5/bin/php -v
/opt/plesk/php/5.6/bin/php -v
/opt/plesk/php/7.0/bin/php -v
/opt/plesk/php/7.1/bin/php -v

Your PHP - commands for possible additional PHP versions ( 7.0 and 7.1 if you installed the sury.org MAIN ppa PHP versions from https://launchpad.net/~ondrej/+archive/ubuntu/php ) would be:

/usr/bin/php7.0 -v
/usr/bin/php7.1 -v

Show the installed modules for each PHP version with the "-m" option string and use the "-i" option string for informations ( example ):

/opt/plesk/php/7.0/bin/php -m
/opt/plesk/php/7.0/bin/php -i
or
/usr/bin/php7.0 -m
/usr/bin/php7.0 -i

To use the "composer", you would certainly as well use the FULL path of your PHP executable ( example ):

/opt/plesk/php/7.0/bin/php composer-setup.php
or
/usr/bin/php7.0 composer-setup.php

Additional "composer" - commands are then:

/opt/plesk/php/7.0/bin/php composer.phar AND-ADDITIONAL-STRINGS/OPTIONS-TO-BE-INCLUDED
or
/opt/plesk/php/7.0/bin/php composer.phar AND-ADDITIONAL-STRINGS/OPTIONS-TO-BE-INCLUDED
