Error masuk Phpmyadmin (UBUNTU 18.04)

Error access denied for user 'root'@'localhost'

Kemudian Ana mencoba dengan beberapa perintah di terminal:
sudo /etc/init.d/mysql stop
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
ana ketikan sudo phpmysql -u root
muncul error
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
penyelesaian :
ketikan di terminal sudo /etc/init.d/mysql start
kemudian ana coba lagi ketikan beberapa perintah

sudo mysql -u root 

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

sudo mysql -u root -p 

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

penyelesaian :
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt install mysql-server

errornya balik lagi ke awal #1698-access denied for user 'root@'localhost''.
Ana coba lagi
sudo service mysql stop
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
kemudian muncul error "Connection for controluser as defined in your configuration failed"
penyelesaian :
sudo gedit /etc/phpmyadmin/config.inc.php

kemudian cari //$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
hilangkan // dari script $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

kemudian simpan maka akan muncul seperti gambar dibawah ini, denga penambahan field didalamnya "server choice"

sudo service mysql stop
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
mysql -u root maka akan muncl error :
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
[5]   Exit 1                  sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking

ketika menggunakan sudo mysql -u root tetap error :
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

ketika ketik sudo service mysql start
kemudian sudo mysql -u root maka berhasil
