i just started webdevelopment on ubuntu in core php and laravel Framework. I have installed php and all the dependencies but mysql is not working indiviually but its working inside lampp

so i began with giving the following command

mysql -u root -p

and the i get the following response(same for runing only 'mysql' and 'sudo mysql')

 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Also when i go to /var/run there is no folder with the name mysqld

cd /var/run/mysqld

bash: cd: /var/run/mysqld: No such file or directory

See this too

cd /var/run 

aq@DevilsBook:/var/run$ ls

acpid.pid     console-setup  dhclient-wlo1.pid  initctl      mount           rsyslogd.pid       sudo        user

acpid.socket  crond.pid      dmeventd-client    initramfs    network         sendsigs.omit.d    systemd     utmp

alsa          crond.reboot   dmeventd-server    lock         NetworkManager  shm                thermald    uuidd

apache2       cryptsetup     fsck               log          php             snapd-snap.socket  tmpfiles.d  wpa_supplicant

avahi-daemon  cups           gdm3               lvm          plymouth        snapd.socket       udev

blkid         dbus           gdm3.pid           lvmetad.pid  pppconfig       spice-vdagentd     udisks2

Other then That there is a folder named mysql and mysql-upgrade in /var/lib..

Then i tried the service mysql start command and it took so much time

sudo service mysql status

[sudo] password for aq: 

● mysql.service - MySQL Community Server

   Loaded: loaded (/lib/systemd/system/mysql.service; bad; vendor preset: enable

   Active: inactive (dead)



[1]+  Stopped                 sudo service mysql status

and run the same comand without sudo and i get

Job for mysql.service failed because the control process exited with error code.

See "systemctl status mysql.service" and "journalctl -xe" for details.

After that i see systemctl status mysql.service and the result was

Even though mysql is working in lamp see the result of lampp runing sudo /opt/lampp/lampp start

aq@DevilsBook:~$ sudo /opt/lampp/lampp start

[sudo] password for aq:

How do i locate the folder and the package to eliminiate this issue ??

Answer from ->> https://www.youtube.com/watch?v=qr-t8ksYO78

go to my.cnf file, note that you will find multiple my.cnf file, i had to look at all of them to find this->

# The MySQL server

[mysqld]

user = mysql

port=3306

socket      = /opt/lampp/var/mysql/mysql.sock

Copy the path and write it like ->

mysql -u root -p --socket=/opt/lampp/var/mysql/mysql.sock 

Thanks
