Mysql can't start

aaP_mutu_institute

when I execute mysql command, this error appear:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
How can I resolve this error?

I tried to start mysql but no response, it still stopped.

I tried to run : /etc/init.d/mysqld start , but this error appear.

I tried log:
cat /www/server/data/*.err|grep -i -C 10 error , this error appear

The first problem appear, when I change storage configuration session php 8.0 from file to memcached, but 30 minutes later suddenly appear 'error database connect ' , I tried to switch-back storage session php to 'files' again. But I can't start mysql.

How to fix this? please help. thankyou

Hello, there is no error in the mysql log information. Are there any other error logs

above is error in hostname.err

and then below is database empty, even there is database in directory /www/server/data ,
t

I also can't login to phpmyadmin, definitely because there is no mysql.sock inside /tmp/ folder. there is only mysql.sock.log

I've tried many way in tutorial & forums but still, mysql wouldn't start. turn website to database error connection on website
